- Abstract
2H‐pyran compound 1 synthesized from 6‐methylpyridine‐2,4‐diol and citral, has been used for Cu‐catalyzed
N ‐arylation with a range of arylboric acids to obtain arylated pyranopyridine core structure derivatives (yield up to 77 %). Among them, compound3 h exhibited a much better inhibitory effect on HepG2 liver cancer cells compared to citral, and the IC50 value was 5.3 μM following exposure with the newly synthesized derivatives (herein named3 h for short in this paper), which was lower than that of the cisplatin (6.5 μM). Meanwhile, the cell‐cycle arrest of HepG2 cells occurred in the S phase, and the apoptosis of HepG2 cells was significantly increased with increasing drug concentration. In addition, real‐time fluorescence quantification PCR and Western blotting experiments showed that the expression of apoptotic protein BAX was increased, while the expression of anti‐apoptotic protein BCL2 was inhibited in a dose‐dependent fashion. The results of these experiments indicated that apoptosis was promoted in HepG2 cells via apoptotic signaling pathway activated by3 h . Furthermore,3 h effectively decreased the phosphorylation levels of PI3 K, ATK and ERK, resulting in the inhibitions of MAPK/ERK and PI3 K/ATK signaling pathways. Briefly,3 h has been found to show inhibitory effects on the survival of HepG2 liver cancer cells and may be used as anti‐cancer drug in the future. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Biofilms are notoriously difficult to eradicate and are a source of many recalcitrant infections. There is effective biofilm management with silver nanoparticles. However, silver nanoparticles that are chemically mediated are extremely harmful to ecosystems. The current study synthesized AgNPs using Cleome rutidosperma leaf extract (CrLE) and analyzed it in UV-VIS, FT-IR, XRD spectroscopy, and TEM for the physical formation and tested with Candida albicans, A431 (Epidermoid carcinoma) cells for its biological efficacy and molecular docking also done. The CrLF has significant phytochemicals such as flavonoids, tannins, terpenoids, and glycosides. The CrLE-AgNPs produced a surface plasmon resonance (SPR) peak at 450 nm in the UV-Vis spectrum and the FT-IR functional groups had -O-H, -N-H stretching at 3423.83 cm-1 due to hydroxyl and amino groups; C=C and C=O stretching at 1632.53 cm
-1 due to flavonoid; and C-H deformation at 1110.42 cm-1 due to AgO formation. The XRD peaks revealed the particle size as 14.07 nm. The TEM and SAED studies confirmed the development of spherical shaped AgNPs with agglomeration. During biological characterization, the synthesized AgNPs produced an inhibitory zone against Candida albicans and its biofilm between 30 μg/mL to 50 μg/mL concentrations and produced cytotoxicity against A431 (epidermoid carcinoma) cells (in vitro) at an IC50 value of 36.56 µg/ml. A molecular docking study revealed that a well-conserved binding region is present and predicted the best binding energy value between Als3 adhesin (PDB ID: 4LE8) and silver oxide nanoparticle is -9.60 kcal/mol. The results of this study show that AgNPs made from the leaf extract of Cleome rutidosperma could be used to treat infections caused by anti-candida. [ABSTRACT FROM AUTHOR]- Published

Introduction: The epidermal growth factor receptor (EGFR) presents a crucial target for combatting cancer mortality. Methods: This study employs a suite of computational techniques, including 3D-QSAR, ligand-based virtual screening, molecular docking, fingerprinting analysis, ADME, and DFT-based analyses (MESP, HOMO, LUMO), supplemented by molecular dynamics simulations and MMGB/PBSA free energy calculations, to explore the binding dynamics of quinazoline derivatives with EGFR. With strong q2 and r2 values from CoMFA and CoMSIA models, our 3D- QSAR models reliably predict EGFR inhibitors' efficacy. Results and Discussion: Utilizing a potent model compound as a reference, an E-pharmacophore model was developed to sift through the eMolecules database, identifying 19 virtual screening hits based on ShapeTanimoto, ColourTanimoto, and TanimotoCombo scores. These hits, assessed via 3D- QSAR, showed pIC
50 predictions consistent with experimental data. Our analyses elucidate key features essential for EGFR inhibition, reinforced by ADME studies that reveal favorable pharmacokinetic profiles for most compounds. Among the primary phytochemicals examined, potential EGFR inhibitors were identified. Detailed MD simulation analyses on three select ligands—1Q1, 2Q17, and VS1—demonstrated their stability and consistent interaction over 200 ns, with MM/GBSA values corroborating their docking scores and highlighting 1Q1 and VS1's superior EGFR1 affinity. These results position VS1 as an especially promising lead in EGFR1 inhibitor development, contributing valuable insights towards crafting novel, effective EGFR1 inhibitors.

Introduction: Phosphoinositide-3-kinase (PI3K) is overexpressed in many tumors and is, thus, an ideal target for cancer treatments. Accordingly, there is an urgent need for the development of PI3K inhibitors with high potency and low toxicity. Methods: In this study, we designed and synthesized a series of 2,4-dimorpholinopyrimidine-5-carbonitrile derivatives, which were evaluated for their PI3K inhibitory potency. Results and discussion: Compound 17p demonstrated comparable PI3Kα inhibitory activity (IC
50 : 31.8 ± 4.1 nM) to the positive control, BKM-120 (IC50 : 44.6 ± 3.6 nM). In addition, 17p showed significant inhibitory activity against PI3Kδ (IC50 : 15.4 ± 1.9 nM) and significant isoform selectivity against PI3Kβ, PI3Kγ, and mTOR. Furthermore, 17p exhibited good antiproliferative activities against cancer cell activity and good safety in the Ames and hERG tests while having outstanding liver microsomal stability in vitro , with half-lives of 38.5 min in rats and 127.9 min in humans. In addition, in an apoptosis assay, 17p could induce dose-dependent cytotoxicity in the ovarian cancer cell line A2780. In a pharmacokinetic study, 17p was stable (T½ : 2.03 h) and showed high bioavailability (46.2%). Collectively, these results indicate that 17p could be a promising PI3K agent for cancer treatment.

Fluorometric determination of different biologically, industrially, and environmentally important analytes is a powerful technique because this technique has excellent selectivity, high sensitivity, rapid photoluminescence response, low cost, applicability to bioimaging, and low detection limit. Fluorescence imaging is a powerful technique for screening different analytes in the living system. Heterocyclic organic compounds have been extensively used as a fluorescence chemosensor for the determination of different biologically important cations like Co2+, Zn2+, Cu2+, Hg2+, Ag+, Ni2+, Cr3+, Al3+, Pd2+, Fe3+ Pt2+, Mn2+, Sn2+, Pd2+, Au3+, Pd2+, Cd2+, Pb2+ and other ions in biological and environmental systems. These compounds also showed significant biological applications such as anti-cancer, anti-ulcerogenic, antifungal, anti-inflammatory, anti neuropathic, antihistaminic, antihypertensive, analgesic, antitubercular, antioxidant, antimalarial, antiparasitic, antiglycation, antiviral anti-obesity, and antibacterial potency. In this review, we summarize the heterocyclic organic compounds based on fluorescent chemosensors and their applications in bioimaging studies for the recognition of different biologically important metal ions.

Calotropis gigantea essential oil is utilized in outmoded medicine, therapeutics, and the cosmetic industries. However, the extreme volatility, oxidation susceptibility, and instability of this oil restricts its application. Thus, encapsulation is a more effective method of shielding this oil from unfavorable circumstances. The creation of oil/water (O/W) nanoemulsions based on Calotropis gigantea essential oil (CEO), known as CNE (Calotropis gigantea essential oil nanoemulsions), and an assessment of its biological potential were the goals of this work. UV, fluorescence, and FT-IR methods were used for physiological characterization. Biological activities, including anti-inflammatory, anti-diabetic, and anti-cancer effects. Studies on the pharmacokinetics of CNE were conducted. CNEs encapsulation efficiency was found to be 92%. The CNE nanoemulsions had a spherical shape with polydispersity index of 0.531, size of 200 nm, and a zeta potential of −35.9 mV. Even after being stored at various temperatures for 50 days, CNE nanoemulsions remained stable. Numerous tests were used to determine the antioxidant capacity of CNE, and the following IC50 values (µl/mL) were found: iron chelating assay: 18, hydroxyl radical scavenging: 37, and nitric oxide radical scavenging activity: 58. The percentage of HeLa cells that remained viable after being treated with CNE was 41% at a higher dose of 1 µl. CNE inhibited α-amylase in a dose-dependent manner, with 72% inhibition at its higher dose of 250 µL. Research on the kinetics of drugs showed that nanoemulsions showed Higuchi pattern. This research showed potential use of Calotropis gigantea oil-based nanoemulsions in the food, cosmetic, and pharmaceutical industries. [ABSTRACT FROM AUTHOR]

Novel compounds with pharmacological activity were synthesized from Pd (II), Fe (III), Cr (III), Ni (II), and Cu (II) ions with 4‐{2‐(3‐carboxy‐1‐cyclopropyl‐6‐fluoro‐7‐piperazin‐1‐yl‐2,3‐dihydro‐1H‐quinolin‐4‐ylideneamino)‐phenylimino}‐1‐cyclopropyl‐6‐fluoro‐7‐piperazin‐1‐yl‐1,4‐dihydro‐quinoline‐3‐carboxylic acid (CFPD). The newly synthesized compounds have been investigated by 1H‐ and 13C‐NMR spectra, Fourier transform infrared spectra, CHN analyses, ultraviolet‐visible spectra, mass spectra, molar conductivity, and magnetic moment measurements. In addition, the pH profile of the CFPD complexes showed remarkable stability, and their stability constant was identified in solution. To find out essential characteristics for CFPD and its complexes and to investigate the molecular geometry, computational analysis occurred. Through its nitrogen and OH of carboxylate groups, the ligand interacted with the metal ions to form CFPDPd complex with a square planar geometry and CFPDCu, CFPDCr, CFPDNi, and CFPDFe complexes with octahedral geometry. The M:L ratio of 1:1 was demonstrated by the molar ratio and sequence variation techniques' outcomes. The effect of the investigated CFPD imine ligand on bacterial community and its metal chelate was examined within vitro using a range of fungal and viral pathogens The findings showed that the effectiveness of antimicrobial went with the directive: CFPDPd complex when compared to the highly suppressor complex, fluconazol and ofloxacin as model medication. The novel ligand's and its complexes' in vitro cytotoxic potential against the Hep‐G2, MCF‐7, and HCT‐116 cell lines was also studied. The findings once more indicated that, when compared to vinblastine medication, the CFPDPd chelate is the most active agent. In addition, the complexes showed high reactivity in catching free radicals when their antioxidant activity was examined. By the application of viscosity, spectrum analysis, and gel electrophoreses, the interaction among metal chelates and DNA was determined. Studies on viscosity and spectrophotometric titration showed that every substance in test is a strong DNA binder. Increased hydrophobic and electrostatic interactions between aromatic rings could be the cause of this. In conclusion, these complexes have the potential to be effective bioactive agents.

Photo‐triggered ROS‐responsive supramolecular nanoprodrugs (BNN6@GBTC NPs) are constructed via supramolecular self‐assembly of amphiphilic prodrug molecule (GBTC) and NO donor (BNN6). BNN6@GBTC NPs possess good stability, ROS responsiveness, and selective HepG2 cells targetability via overexpressed galactose receptors on the cell membrane. When BNN6@GBTC NPs are taken up by HepG2 cells, they can generate ROS upon light irradiation, which can not only be used for photodynamic therapy, but also cleave the thioketal linkage to release camptothecin for chemotherapy. Meanwhile, BNN6 triggering release NO for gas therapy. BNN6@GBTC NPs enable targeted and synergistic chemo/photodynamic/gas therapy, which results in reduced damage to normal cells and enhanced anti‐cancer efficacy
in vitro . This work provides a novel approach for the design of nanoprodrugs based on supramolecular self‐assembly to achieve the multimodal synergistic anti‐cancer therapy. [ABSTRACT FROM AUTHOR]- Published

- Abstract
A new group of thiazolidine-2,4-dione derivatives of ciprofloxacin having butyryl linker 3a-l was synthesized via an alkylation of thiazolidine-2,4-diones with butyryl ciprofloxacin with yield range 48–77% andfully characterized by various spectroscopic and analytical tools. Anti-cancer screening outcomes indicated that 3a and 3i possess antiproliferative activities against human melanoma LOX IMVI cancer cell line with IC50 values of 26.7 ± 1.50 and 25.4 ± 1.43 µM, respectively, using doxorubicin and cisplatin as positive controls with an IC50 of 7.03 ± 0.40 and 5.07 ± 0.29 µM, respectively. Additionally, compound 3j showed promising anticancer activity against human renal cancer A498 cell line with IC50 value of 33.9 ± 1.91 µM while doxorubicin and cisplatin showed IC50 values of 3.59 ± 0.20 and 7.92 ± 0.45, respectively. On the other hand, compound 3i did not show considerable anti-bacterial activity against S. aureus, E. coli and P. aeruginosa, and only moderate activity against K. pneumoniae with only a tenth of the activity of ciprofloxacin, confirming the cytotoxicity observed. Mechanistically, compound 3i inhibited both topoisomerase I and II with IC50 of 4.77 ± 0.26 and 15 ± 0.81 µM. Furthermore, it induced cell cycle arrest at S phase in melanoma LOX IMVI cells. Moreover, 3i provoked substantial levels of early, late apoptosis and necrosis in melanoma LOX IMVI cell line comparable to that induced by doxorubicin. Furthermore, compound 3i increased the expression level of active caspase-3 by 49 folds higher in LOX IMVI cell, increased protein expression level of Bax more than the control by 3 folds and inhibited PARP-1by 33% in LOX IMVI. All results were supported by theoretical docking studies on both tested enzymes confirming potential cytotoxicity for the synthesized hybrids. [ABSTRACT FROM AUTHOR]

This study describes the synthesis of N5‐(4‐(1H‐benzo[d]imidazol‐2‐yl)phenyl)‐N2‐phenylpyridine‐2,5‐diamine derivatives from Orthophenylenediamine (1) and 4‐aminobenzoic acid (2) and all the synthesized chemical moieties screened against a panel of cancer cell lines resulted in the identification compound 6 a with good anti‐cancer potential and a GI50 of 2.95 μM, 3.35 μM, 2.27 μM, 8.46 nM and 1.56 μM against MDAMB‐231, MCF‐7, A‐549, NCI‐H23 and A‐498 respectively. As the second greatest cause of death globally, cancer continues to pose a serious threat to public health. An essential enzyme called aromatase catalyses the last, rate‐limiting step in the production of oestrogens. As a well‐researched endocrine therapeutic strategy, aromatase inhibitors (AIs) efficiently block the production of oestrogen, which is necessary for aromatase activity. [ABSTRACT FROM AUTHOR]

- Abstract
Seaweed endophytes are a rich source of microbial diversity and bioactive compounds. This review provides a comprehensive analysis of the microbial diversity associated with seaweeds and their interaction between them. These diverse bacteria and fungi have distinct metabolic pathways, which result in the synthesis of bioactive compounds with potential applications in a variety of health fields. We examine many types of seaweed-associated microorganisms, their bioactive metabolites, and their potential role in cancer treatment using a comprehensive literature review. By incorporating recent findings, we hope to highlight the importance of seaweed endophytes as a prospective source of novel anticancer drugs and promote additional studies in this area. We also investigate the pharmacokinetic and pharmacodynamic profiles of these bioactive compounds because understanding their absorption, distribution, metabolism, excretion (ADMET), and toxicity profiles is critical for developing bioactive compounds with anticancer potential into effective cancer drugs. This knowledge ensures the safety and efficacy of proposed medications prior to clinical trials. This study not only provides promise for novel and more effective treatments for cancer with fewer side effects, but it also emphasizes the necessity of sustainable harvesting procedures and ethical considerations for protecting the delicate marine ecology during bioprospecting activities.

Mahaveerchand, Harshika and Abdul Salam, Abdul Ajees
- Abstract
The rise of air, water, and soil pollution poses a significant threat to global health, leading to widespread disease and premature mortality. Soil health is vital, ensuring the production of safe food, but it is compromised by pollutants such as heavy metals, pesticides, plastics, and excessive fertilization, resulting in the depletion of beneficial microorganisms and subsequently groundwater contamination. Water bodies are polluted due to contamination from industrial effluents, domestic wastewater, agricultural runoff, and oil spillage, further intensifying environmental pollution. On the other hand, atmospheric pollution, characterized by high emissions of gases, volatile compounds, greenhouse gases, not only impacts the climate but also poses serious risks to human health, leading to respiratory diseases, cardiovascular issues, and increased cancer risks. Thus, the strategic utilization of traditional plants emerges as a potent tool for environmental restoration and improving human health. The plants possess natural filtering capabilities, absorbing pollutants from air, soil, and water, thus mitigating their adverse effects. Through phytoremediation, plants can be actively used to extract and remove contaminants, contributing to detoxification and improving water and soil quality. Additionally, plants offer various health benefits. Moringa oleifera or the drumstick plant belonging to the Moringaceae family is one such indigenous plant with wide applications, that can be grown in extreme arid conditions. Since ancient times, this plant has been used for treating skin infections, anaemia, and blood impurities. This plant thrives in diverse climates addressing over 300 different aliments. Rich in phytochemicals and bioactive compounds, M. oleifera serve as a superfood, offering high nutritional values and exhibiting potential for drug development with fewer side effects. Extensive research has elucidated the diverse properties and applications of M. oleifera, however, in-depth research is needed to identify bioactive molecules, phytochemicals, and protein compounds involved, which will aid in understanding of the mechanisms of action of the plant's diverse functions. Although studies have reported several of individual M. oleifera attributes, there is no comprehensive study available addressing its diverse applications. This review covers the findings of past three decades and provides a detailed outline of M. oleifera plant and its various parts, its applications in environmental, industrial, food and health aspects documented to date.

Featured Application: The application of this study is all computational studies considering venom peptides as potential sources of therapeutics. Animal venom has been gaining traction as a potential source of therapeutics for various diseases. Spiders encompass a wide variety of venom-producing species, of which tarantulas of the family Theraphosidae are widely known across the globe. Research towards tarantula venom therapeutics has led to its potential application as antinociceptives. Death receptors are cellular receptors that induce apoptosis—the body's natural suicide mechanism—to destroy malfunctioning cells. These are particularly of interest in cancer research, as this mechanism is tampered with, resulting in cancer cell proliferation. In this study, the viability of venom toxins from the Theraphosidae family of spiders to induce apoptosis by binding to human death receptors is investigated by carrying out anti-cancer screening, molecular docking, ADMET evaluation, then molecular dynamics and thermodynamic analysis twice, first to ascertain the best receptor–peptide systems per receptor, and secondly to more comprehensively describe binding stability and thermodynamics. Results point to favorable receptor–peptide interactions due to similarities in equilibrium behavior with the death ligand–death receptor systems, along with favorable end-state binding energies and ADMET analysis results. Further inquiry is recommended to assess the real-life efficacy and viability of theraphotoxins as apoptosis therapeutics and further improve on their ability to induce apoptosis.

Our study aimed to develop dicarboxylic acid-derivatized C60 fullerenes as a novel DTX delivery carrier. This study investigated the potential of water-soluble fullerenes to deliver the anti-cancer drug DTX through a hydrophilic linker. The synthesis was carried out using the Prato reaction. The spectroscopic analysis confirmed the successful conjugation of DTX molecules over fullerenes. The particle size of nanoconjugate was reported to be 122.13 ± 1.63 nm with a conjugation efficiency of 76.7 ± 0.14%. The designed conjugate offers pH-dependent release with significantly less plasma pH, ensuring maximum release at the target site. In-vitro cell viability studies demonstrated the enhanced cytotoxic nature of the developed nanoconjugate compared to DTX. These synthesized nanoscaffolds were highly compatible with erythrocytes, indicating the safer intravenous route administration. Pharmacokinetic studies confirmed the higher bioavailability (~ 6 times) and decreased drug clearance from the system vis-à-vis plain drug. The histological studies reveal that nanoconjugate-treated tumour cells exhibit similar morphology to normal cells. Therefore, it was concluded that this developed formulation would be a valuable option for clinical use. [ABSTRACT FROM AUTHOR]- Published

- Abstract
The use of drugs in chemotherapy poses numerous side effects. Hence the use of natural substances that can help in the prevention and cure of the disease is a dire necessity. Cancer is a deadly illness and combination of diseases, the menace of which is rising with every passing year. The research community and scientists from all over the world are working towards finding a cure of the disease. The use of polyphenols which are naturally derived from plants have a great potential to be used as anti-cancer drugs and also the use of fruits and vegetables which are rich in these polyphenols can also help in the prevention of diseases. The study aims to compile the available literature and research studies on the anti-cancer effects of polyphenols and the signaling pathways that are affected by them. To review the anti-cancer effects of polyphenols, Google Scholar, PubMed and ScienceDirect were used to study the literature available. The article that have been used for literature review were filtered using keywords including cancer, polyphenols and signaling pathways. Majorly articles from the last 10 years have been considered for the review but relevant articles from earlier than 10 years have also been considered. Almost 400 articles were studied for the review and 200 articles have been cited. The current review shows the potential of polyphenols as anti-cancer compounds and how the consumption of a diet rich in polyphenols can help in the prevention of cancer. Because of their capacity to affect a variety of oncogenic and oncosuppressive signaling pathways, phytochemicals derived from plants have been effectively introduced as an alternative anticarcinogenic medicines.

Background: Pancreatic and Gastric cancers are very aggressive and deadly types of cancer that require effective treatment strategies to stop their progression. Nano-drug delivery systems, like those using Auraptene-loaded GQD nanoparticles, play a crucial role in addressing this need by delivering targeted and controlled treatments to cancer cells, making treatment more effective, and reducing side effects. The study focused on investigating the effects of Auraptene, an efficient anticancer compound when loaded into Graphene Quantum Dots (GQDs) on types of human cancer cells. Methods: To create auraptene-loaded graphene quantum dot nanoparticles (AGQD-NP) (Unmodified and modified types) a combination of hydrothermal and high-energy homogenization methods was used. The nanoparticles were characterized by conducting DLS (Dynamic light scattering), FTIR (Fourier-transform infrared spectroscopy), FESEM (Field Emission Scanning Electron microscopy), and zeta potential analysis. bioactivity of AGQD-NP was assessed through tests, including antioxidant capacity measured by ABTS and DPPH scavenging abilities well as cytotoxicity tested using MTT assay on both human cancer cell lines and normal human vascular endothelial cells. Results: The modified AGQD-NP (M-AGQD-NP) demonstrated antioxidant properties by neutralizing free radicals. They also displayed selective toxicity, towards human gastric adenocarcinoma cell-line (AGS) and human pancreatic adenocarcinoma (PANC) cancer cells with IC50 values recorded at 78.8 µg/mL and 89.72 µg/mL respectively. The specific targeting of gastric cancer cells was evident from the differing IC
50 values compared to the Human breast adenocarcinoma cell line (MCF-7), Human hepatocellular carcinoma cell line (Hella), and normal vascular endothelial cells (Huvec). Additionally, the induced apoptotic death, in the human pancreatic adenocarcinoma (PANC) cancer cells was confirmed through AO/PI staining and Annexin-based flow cytometry revealing increased expression levels of P53, Caspase3, BAX, and Caspase8. Conclusion: In summary, the M-AGQD-NP have shown encouraging effects displaying antioxidant capabilities and a specific focus, on pancreatic and gastric cancer cells. These findings indicate uses for AGQD-NP as an efficient apoptosis inducer in cancer treatment. Additional In-vivo researches are required to validate their effectiveness, in living organisms.

- Abstract
The cAMP-responsive element binding protein (CREB) binding protein (CBP), a bromodomain-containing protein, engages with multiple transcription factors and enhances the activation of many genes. CBP bromodomain acts as an epigenetic reader and plays an important role in the CBP-chromatin interaction which makes it an important drug target for treating many diseases. Though inhibiting CBP bromodomain was reported to have great potential in cancer therapeutics, approved CBP bromodomain inhibitor is yet to come. We utilized various in silico approaches like molecular docking, ADMET, molecular dynamics (MD) simulations, MM-PBSA calculations, and in silico PASS predictions to identify potential CBP bromodomain inhibitors from marine natural compounds as they have been identified as having distinctive chemical structures and greater anticancer activities. To develop a marine natural compound library for this investigation, Lipinski’s rule of five was used. Sequential investigations utilizing molecular docking, ADMET studies, 100 ns MD simulations, and MM-PBSA calculations revealed that three marine compounds—ascididemin, neoamphimedine, and stelletin A—demonstrated superior binding affinity compared to the standard inhibitor, 69 A. These compounds also exhibited suitable drug-like properties, a favorable safety profile, and formed stable protein-ligand complexes. The in-silico PASS tool predicted that these compounds have significant potential for anticancer activity. Among them, ascididemin demonstrated the highest binding affinity in both molecular docking and MM-PBSA calculations, as well as a better stability profile in MD simulations. Hence, ascididemin can be a potential inhibitor of CBP bromodomain. However, in vitro and in vivo validation is required for further confirmation of these findings. [ABSTRACT FROM AUTHOR]

Simple Summary: Natural polyphenols are well-known dietary supplements that have been used for medical purposes for a long time. Consuming foods and beverages of plant origin, especially those rich in polyphenolic compounds, may have chemopreventive and therapeutic effects on cancer due to the health-promoting properties of these compounds. Polyphenols are characterized by high structural diversity, which contributes to their wide range of therapeutic effects, including anti-oxidant and anti-cancer activities. These compounds can modulate the expression and activity of many proteins, including enzymes, and regulate multiple cell signaling pathways. Among the molecular targets of anti-cancer agents are matrix metalloproteinases, particularly metalloproteinase-2 and metalloproteinase-9, and nuclear factor-kappa B. Matrix metalloproteinases can degrade the protein components of the extracellular matrix and play key roles in physiological processes such as tissue repair and morphogenesis, as well as in carcinogenesis and other pathological processes. The inhibition of their synthesis and activity is closely related to a reduction in the metastasis and invasion of cancer cells. This review discusses the current state of knowledge concerning the anti-invasive and anti-metastatic potential of selected polyphenols, with a focus on in vitro and in vivo evidence. Polyphenols are natural compounds found in many plants and their products. Their high structural diversity bestows upon them a range of anti-inflammatory, anti-oxidant, proapoptotic, anti-angiogenic, and anti-metastatic properties, and a growing body of research indicates that a polyphenol-rich diet can inhibit cancer development in humans. Polyphenolic compounds may modulate the expression, secretion, or activity of compounds that play a significant role in carcinogenesis, including type IV collagenases, such as matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9), by suppressing cellular signaling pathways such as nuclear factor-kappa B. These enzymes are responsible for the degradation of the extracellular matrix, thus promoting the progression of cancer. This review discusses the current state of knowledge concerning the anti-cancer activity of polyphenols, particularly curcumin, resveratrol, epigallocatechin-3-gallate, genistein, and quercetin, with a specific focus on their anti-invasive and anti-metastatic potential, based on the most recent in vitro and in vivo studies. It appears that polyphenols may be valuable options for the chemoprevention and treatment of cancer via the inhibition of MMP-2 and MMP-9 and the suppression of signaling pathways regulating their expression and activity.

Epithelial ovarian carcinoma poses a significant challenge due to its resistance to chemotherapy and propensity for metastasis, thereby reducing the effectiveness of conventional treatments. Hence, the identification of novel compounds capable of augmenting the anti-cancer efficacy of platinum-based chemotherapy is imperative. Oxyresveratrol (OXY), a derivative of resveratrol, has been demonstrated to possess antiproliferative and apoptosis-inducing effects across various cancer cell lines. Notably, OXY appears to exert its effects by inhibiting the PI3K/AKT/mTOR signaling pathway. However, the synergistic potential of OXY in combination with cisplatin against epithelial ovarian cancer has not yet been elucidated. The current study investigated the synergistic effects of OXY and cisplatin on the ovarian cancer cell lines SKOV3 and TOV21G. We found that OXY significantly enhanced cisplatin's ability to reduce cell viability, induce apoptosis, induce cell cycle arrest, and increase the proportion of cells in the sub-G1 phase. Furthermore, OXY treatment alone dose-dependently inhibited the production of anti-apoptotic proteins including Mcl-1, Bcl-xL, and XIAP under EGF activation. Mechanistically, OXY suppressed the PI3K/AKT/mTOR signaling pathway by reducing phosphorylated AKT, while having no discernible effect on the MAPK pathway. These findings highlight OXY's potential to enhance ovarian cancer cell sensitivity to chemotherapy, suggesting its development as a pharmaceutical adjunct for clinical use in combination therapies.

Skin cancer is threatening more and more people's health; its postoperative recurrence and wound infection are still critical challenges. Therefore, specialty wound dressings with multifunctional bioactivity are urgently desired. Emodin is a natural anthraquinone compound that has anti-cancer and anti-bacterial properties. Herein, we fabricated coaxial electrospinning nanofibers loaded with emodin to exploit a multifunctional wound dressing for skin cancer postoperative management, which encapsulated emodin in a polyvinylpyrrolidone core layer, combined with chitosan-polycaprolactone as a shell layer. The nanofibers were characterized via morphology, physicochemical nature, drug load efficiency, pH-dependent drug release profiles, and biocompatibility. Meanwhile, the anti-cancer and anti-bacterial effects were evaluated in vitro. The emodin-loaded nanofibers exhibited smooth surfaces with a relatively uniform diameter distribution and a clear shell-core structure; remarkably, emodin was evenly dispersed in the nanofibers with significantly enhanced dissolution of emodin. Furthermore, they not only display good wettability, high emodin entrapment efficiency, and biphasic release profile but also present superior biocompatibility and anti-cancer properties by increasing the levels of MDA and ROS in A-375 and HSC-1 cells via apoptosis-related pathway, and long-term anti-bacterial effects in a dose-independent manner. The findings indicate that the emodin-loaded nanofiber wound dressing can provide a potential treatment strategy for skin cancer postoperative management. [ABSTRACT FROM AUTHOR]

Ovarian cancer, a leading cause of cancer-related deaths in women, remains a formidable challenge, especially in the context of platinum-resistant disease. This study investigated the potential of the benzimidazole derivative BNZ-111 as a novel treatment strategy for platinum-resistant ovarian cancer. The human EOC cell lines A2780, HeyA8, SKOV3ip1, A2780-CP20, HeyA8-MDR, and SKOV3-TR were treated with BNZ-111, and cell proliferation, apoptosis, and cell cycle were assessed. It demonstrated strong cytotoxicity in both chemo-sensitive and chemo-resistant epithelial ovarian cancer cell lines, inducing apoptosis and G2/M cell cycle arrest. In vivo experiments using orthotopic and patient-derived xenograft models showed significant tumor growth inhibition without apparent toxicity to vital organs. Unlike paclitaxel, BNZ-111 proved effective in paclitaxel-resistant cells, potentially by bypassing interaction with MDR1 and modulating β-3 tubulin expression to suppress microtubule dynamics. BNZ-111, with favorable drug-like properties, holds promise as a therapeutic option for platinum-resistant ovarian cancer, addressing a critical clinical need in gynecologic oncology. [Display omitted] • The benzimidazole derivative BNZ-111 may be a novel treatment for ovarian cancer. • Disrupting tubulin polymerization is a mechanism of action through which BNZ-111 induces anti-cancer activity. • BNZ-111 demonstrates in vivo efficacy and potential for overcoming paclitaxel resistance.

- Abstract
The manipulation of the energy or source of food for cancer cells has attracted significant attention in oncology research. Metabolic reprogramming of the immune system allows for a deeper understanding of cancer cell mechanisms, thereby impeding their progression. A more targeted approach is the restriction of cancer cells through dietary restriction (CR), which deprives cancer cells of the preferred energy sources within the tumor microenvironment, thereby enhancing immune cell efficacy. Although there is a plethora of CR strategies that can be employed to impede cancer progression, there is currently no comprehensive review that delineates the specific dietary restrictions that target the diverse metabolic pathways of cancer cells. This mini-review introduces amino acids as anti-cancer agents and discusses the role of dietary interventions in cancer prevention and treatment. It highlights the potential of a ketogenic diet as a therapeutic approach for cancer, elucidating its distinct mechanisms of action in tumor progression. Additionally, the potential of plant-based diets as anti-cancer agents and the role of polyphenols and vitamins in anti-cancer therapy were also discussed, along with some prospective interventions for CR as anti-tumor progression.

DRUG therapy ,CANCER chemotherapy ,ANTINEOPLASTIC agents ,CANCER treatment ,CANCER patients - Abstract
Natural products have proven to be promising anti-cancer agents due to their diverse chemical structures and bioactivity. This review examines their central role in cancer treatment, focusing on their mechanisms of action and therapeutic benefits. Medicinal plants contain bioactive compounds, such as flavonoids, alkaloids, terpenoids and polyphenols, which exhibit various anticancer properties. These compounds induce apoptosis, inhibit cell proliferation and cell cycle progression, interfere with microtubule formation, act on topoisomerase targets, inhibit angiogenesis, modulate key signaling pathways, improve the tumor microenvironment, reverse drug resistance and activate immune cells. Herbal anti-cancer drugs offer therapeutic advantages, particularly selective toxicity against cancer cells, reducing the adverse side effects associated with conventional chemotherapy. Recent studies and clinical trials highlight the benefits of herbal medicines in alleviating side effects, improving tolerance to chemotherapy and the occurrence of synergistic effects with conventional treatments. For example, the herbal medicine SH003 was found to be safe and potentially effective in the treatment of solid cancers, while Fucoidan showed anti-inflammatory properties that are beneficial for patients with advanced cancer. The current research landscape on herbal anticancer agents is extensive. Numerous studies and clinical trials are investigating their efficacy, safety and mechanisms of action in various cancers such as lung, prostate, breast and hepatocellular carcinoma. Promising developments include the polypharmacological approach, combination therapies, immunomodulation and the improvement of quality of life. However, there are still challenges in the development and use of natural products as anti-cancer drugs, such as the need for further research into their mechanisms of action, possible drug interactions and optimal dosage. Standardizing herbal extracts, improving bioavailability and delivery, and overcoming regulatory and acceptance hurdles are critical issues that need to be addressed. Nonetheless, the promising anticancer effects and therapeutic benefits of natural products warrant further investigation and development. Multidisciplinary collaboration is essential to advance herbal cancer therapy and integrate these agents into mainstream cancer treatment. [ABSTRACT FROM AUTHOR]

- Abstract
Herein, we report the preparation of nickel oxide (NiO) nanosheets in a lyotropic liquid crystal (LLC) medium via a chemical reduction method. The LLC phase exhibiting a lamellar phase was formed using a binary mixture of triton X-100 (68 wt%) and water (32 wt%) at 4 °C. The nanomaterials were prepared in this medium by reducing NiCl
2 .6H2 O using a strong reducing agent, NaBH4 . The prepared nanomaterials were characterized through UV–Vis, SEM, FT-IR and XPS techniques. The NiO nanomaterials were found to exhibit good catalytic activity towards reduction and degradation reactions. An apparent rate constant (Kapp ) value of 1.4 × 10–2 min−1 was obtained for the reduction reaction of 4-nitrophenol to 4-aminophenol using NiO nanomaterials (300 μL of as-prepared 80 mM dispersion). The nanomaterials showed good recyclability with effective activity until 5th cycle. Further, Kapp of 0.5 × 10–2 min−1 was obtained for the degradation reaction of methylene blue. The anti-bacterial studies suggested that the NiO nanomaterials were effective against gram positive (S. aureus) bacteria and anti-cancer studies of the particles against breast cancer cells (MCF-7) showed an IC50 value of 78.93 μg/mL.

Objective: Phyto-oxylipins are lipid molecules produced in plants by the oxidative transformation of unsaturated fatty acids via diverse metabolic pathways. Recently, the chemical diversity and functional significance of oxylipins is gaining significant attention. However, the functional significance of these compounds as anti-cancer agents remains largely uncharacterized. The objective of this review is to provide a comprehensive synthesis and analysis of the functional significance of plant oxylipins as anti-cancer agents to facilitate their exploitation in drug discovery and development. Methods: This review was based on a thorough compilation and analysis of research work carried out on biological significance and implications of plant-derived anti-cancer oxylipins. Curation of data was based on several databases and resources such as Scopus, PubMed, DrugBank and PubChem. Within the context of the scope and subject matter as guided by the objective, no exclusion and inclusion criteria were necessarily employed in the screening of articles. Results: The present review explores the origins, anti-cancer properties and functional mechanisms of phyto-oxylipins. The potential functional significance of new and poorly characterized plant oxylipins have also been highlighted. The prospects of plant oxylipins in research, medicine and biotechnology that could optimize their potential are also explored. Insights into the promising avenues that may originate from innovative therapeutic approaches are also discussed. Conclusion: Despite the rich source of oxylipins in plants, much of their potential as therapeutic agents for cancer treatment remains to be fully established. Clinical investigations are also needed to determine safe doses and effective delivery methods. Research into phyto-oxylipins require significant attention due to the promise it may hold in addressing key challenges in biotechnology, health, and environmental sustainability.

There have been many studies reporting that the regular consumption of fruits and vegetables is associated with reduced risks of cancer and age-related chronic diseases. Recent studies have demonstrated that reducing reactive oxygen species and inflammation by phytochemicals derived from natural sources can extend lifespans in a range of model organisms. Phytochemicals derived from fruits and vegetables have been known to display both preventative and suppressive activities against various types of cancer via in vitro and in vivo research by interfering with cellular processes critical for tumor development. The current challenge lies in creating tailored supplements containing specific phytochemicals for individual needs. Achieving this goal requires a deeper understanding of the molecular mechanisms through which phytochemicals affect human health. In this review, we examine recently (from 2010 to 2024) reported plant extracts and phytochemicals with established anti-aging and anti-cancer effects via the activation of FOXO3 transcriptional factor. Additionally, we provide an overview of the cellular and molecular mechanisms by which these molecules exert their anti-aging and anti-cancer effects in specific model systems. Lastly, we discuss the limitations of the current research approach and outline for potential future directions in this field. [ABSTRACT FROM AUTHOR]

Previously, we synthesized over 30 analogs of α-GalCer and identified a compound, C34, which features two phenyl rings on the acyl chain. C34 exhibited the most potent NKT-stimulating activities, characterized by strong Th1-biased cytokines and potent anti-tumor effects in several murine tumor models. Importantly, unlike α-GalCer, C34 did not induce NKT cell anergy. Despite these promising results, the clinical application of C34 is limited by its poor aqueous solubility. PEGylation enhances the solubility of hydrophobic drugs, and numerous PEGylated drugs have received clinical approval. Consequently, we assessed the biological activity of PEGylated C34 in this study.Methods: Murine NK1.2 cells were cultured with A20-CD1d cells in the presence of either PEGylated lipid nanocarriers encapsulating C34 (PLN-C34) or C34 dissolved in DMSO to determine IL-2 production via ELISA. C57BL/6 mice were i.v. injected with C34 or PLN-C34 to examine cytokine profiles and immune cell populations using luminex and flow cytometry, respectively. The anticancer effects of C34 and PLN-C34 were evaluated in mice bearing TC-1 lung cancer and B16 melanoma tumors. Additionally, human PBMCs were cultured with C34 or PLN-C34 to measure cytokine production through luminex.Results: PLN-C34 demonstrated a comparable capacity to C34 in activating the NKT cell line in vitro and inducing various cytokines in vivo. Furthermore, treatment with either PLN-C34 or C34 significantly prolonged the survival of TC-1- and B16F10-bearing mice to a similar extent. Additionally, PLN-C34 effectively stimulated cytokine responses in human NKT cells, comparable to those induced by C34.Conclusion: These findings demonstrate that the newly formulated PLN-C34 retains NKT-stimulatory activity and anti-cancer efficacy of C34, supporting the potential of PLN as a solvent for C34 for further development in cancer therapy.Keywords: phenyl-glycolipid, NKT cells, PEGylated lipid nanocarrier, anti-cancer

Abstract Reactive oxygen species (ROS) are essential for cancer signalling pathways and tumour maintenance, making ROS targeting a promising anti-cancer strategy. Coenzyme Q10 (CoQ10) has been shown to be effective against various cancers, but its impact on retinoblastoma, alone or with trolox, remains unreported. Cytotoxicity of CoQ10 alone and with trolox was evaluated in normal human retinal pigment epithelium cells (ARPE-19) and Y79 retinoblastoma cells using CCK-8. Flow cytometry was used to assess apoptosis, cell cycle, ROS, and mitochondrial membrane potential (MMP). Anti-angiogenic potential was tested using human umbilical vein endothelial cells (HUVECs) and chick chorioallantoic membrane (CAM) assays. Mechanistic studies were conducted via RT-PCR and western blotting. CoQ10, alone and with trolox, reduced Y79 cell viability, induced apoptosis through excess ROS generation, and decreased MMP significantly. Both treatments caused G2/M phase cell arrest. The CAM assay showed a significant reduction in endothelial cell proliferation, evidenced by fewer number of co-cultured HUVECs when exposed to CoQ10 or CoQ10 with trolox. The combination of CoQ10 and trolox significantly reduced VEGF-A, ERK, and Akt receptor levels, while CoQ10 alone significantly inhibited ERK and Akt phosphorylation. Together, CoQ10 and trolox reduced protein expression of VEGFA. CoQ10 alone and with trolox, induces apoptosis in Y79 retinoblastoma cells by inhibiting the ERK/Akt pathway and downregulating VEGFA. This study is the first to report the in vitro and in-ovo anti-cancer potential of CoQ10 alone or when combined with trolox, on human retinoblastoma Y79 cells.

Abstract A new group of thiazolidine-2,4-dione derivatives of ciprofloxacin having butyryl linker 3a-l was synthesized via an alkylation of thiazolidine-2,4-diones with butyryl ciprofloxacin with yield range 48–77% andfully characterized by various spectroscopic and analytical tools. Anti-cancer screening outcomes indicated that 3a and 3i possess antiproliferative activities against human melanoma LOX IMVI cancer cell line with IC50 values of 26.7 ± 1.50 and 25.4 ± 1.43 µM, respectively, using doxorubicin and cisplatin as positive controls with an IC50 of 7.03 ± 0.40 and 5.07 ± 0.29 µM, respectively. Additionally, compound 3j showed promising anticancer activity against human renal cancer A498 cell line with IC50 value of 33.9 ± 1.91 µM while doxorubicin and cisplatin showed IC50 values of 3.59 ± 0.20 and 7.92 ± 0.45, respectively. On the other hand, compound 3i did not show considerable anti-bacterial activity against S. aureus, E. coli and P. aeruginosa, and only moderate activity against K. pneumoniae with only a tenth of the activity of ciprofloxacin, confirming the cytotoxicity observed. Mechanistically, compound 3i inhibited both topoisomerase I and II with IC50 of 4.77 ± 0.26 and 15 ± 0.81 µM. Furthermore, it induced cell cycle arrest at S phase in melanoma LOX IMVI cells. Moreover, 3i provoked substantial levels of early, late apoptosis and necrosis in melanoma LOX IMVI cell line comparable to that induced by doxorubicin. Furthermore, compound 3i increased the expression level of active caspase-3 by 49 folds higher in LOX IMVI cell, increased protein expression level of Bax more than the control by 3 folds and inhibited PARP-1by 33% in LOX IMVI. All results were supported by theoretical docking studies on both tested enzymes confirming potential cytotoxicity for the synthesized hybrids.

Abstract Background Pancreatic and Gastric cancers are very aggressive and deadly types of cancer that require effective treatment strategies to stop their progression. Nano-drug delivery systems, like those using Auraptene-loaded GQD nanoparticles, play a crucial role in addressing this need by delivering targeted and controlled treatments to cancer cells, making treatment more effective, and reducing side effects. The study focused on investigating the effects of Auraptene, an efficient anticancer compound when loaded into Graphene Quantum Dots (GQDs) on types of human cancer cells. Methods To create auraptene-loaded graphene quantum dot nanoparticles (AGQD-NP) (Unmodified and modified types) a combination of hydrothermal and high-energy homogenization methods was used. The nanoparticles were characterized by conducting DLS (Dynamic light scattering), FTIR (Fourier-transform infrared spectroscopy), FESEM (Field Emission Scanning Electron microscopy), and zeta potential analysis. bioactivity of AGQD-NP was assessed through tests, including antioxidant capacity measured by ABTS and DPPH scavenging abilities well as cytotoxicity tested using MTT assay on both human cancer cell lines and normal human vascular endothelial cells. Results The modified AGQD-NP (M-AGQD-NP) demonstrated antioxidant properties by neutralizing free radicals. They also displayed selective toxicity, towards human gastric adenocarcinoma cell-line (AGS) and human pancreatic adenocarcinoma (PANC) cancer cells with IC50 values recorded at 78.8 µg/mL and 89.72 µg/mL respectively. The specific targeting of gastric cancer cells was evident from the differing IC50 values compared to the Human breast adenocarcinoma cell line (MCF-7), Human hepatocellular carcinoma cell line (Hella), and normal vascular endothelial cells (Huvec). Additionally, the induced apoptotic death, in the human pancreatic adenocarcinoma (PANC) cancer cells was confirmed through AO/PI staining and Annexin-based flow cytometry revealing increased expression levels of P53, Caspase3, BAX, and Caspase8. Conclusion In summary, the M-AGQD-NP have shown encouraging effects displaying antioxidant capabilities and a specific focus, on pancreatic and gastric cancer cells. These findings indicate uses for AGQD-NP as an efficient apoptosis inducer in cancer treatment. Additional In-vivo researches are required to validate their effectiveness, in living organisms.

Background: Metformin is widely prescribed for type 2 diabetes mellitus and is recognized for its therapeutic benefits beyond glycemic control. This review summarizes current data on metformin's diverse roles in various therapeutic contexts, including treating polycystic ovarian syndrome (PCOS), anti-inflammatory effects, and cancer prevention. Method: This comprehensive examination highlights the multifaceted applications of metformin in modern medicine and its potential to enhance the treatment of inflammatory diseases, cancer, and reproductive disorders. Results and Discussion: Metformin's anti-inflammatory properties may benefit autoimmune disorders, neurological diseases, and cardiovascular illnesses. In women with PCOS, metformin aids in restoring menstrual regularity, inducing ovulation, and improving reproductive outcomes by enhancing insulin sensitivity, modulating ovarian function, and reducing hyperandrogenism. Additionally, emerging evidence suggests that metformin may reduce cancer incidence and mortality in diabetic individuals by modulating cellular metabolism, inducing apoptosis, and inhibiting tumor cell proliferation. Conclusion: Our review suggests promising evidence for metformin's role in cancer prevention, reducing inflammation, and managing PCOS. However, further research is required to identify patient subgroups that will benefit most from metformin therapy, elucidate its mechanisms of action, and optimize dosing regimens.

To circumvent these limitations, the strategic employment of nanocarriers and other drugs in combination with BBR is emerging as a focus to potentiate its anti-cancer efficacy. Nano-delivery systems increase drug concentration at the tumor site by improving pharmacological activity and tissue distribution, enhancing drug bioavailability. Organic nanocarriers have advantages for berberine delivery including biocompatibility, encapsulation, and controlled release of the drug. While the advantages of inorganic nanocarriers for berberine delivery mainly lie in their efficient loading ability of the drug and their slow release ability of the drug.

Abstract A very practical method for the synthesis of unsymmetrical carbamide derivatives in good to excellent yield was presented, without the need for any catalyst and at room temperature. Using a facile and robust protocol, fifteen unsymmetrical carbamide derivatives (9–23) bearing different aliphatic amine moieties were designed and synthesized by the reaction of secondary aliphatic amines with isocyanate derivatives in the presence of acetonitrile as an appropriate solvent in good to excellent yields. Trusted instruments like IR, mass spectrometry, NMR spectra, and elemental analyses were employed to validate the purity and chemical structures of the synthesized compounds. All the synthesized compounds were tested as antimicrobial agents against some clinically bacterial pathogens such as Salmonella typhimurium, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans. Compounds 15, 16, 17, 19 and 22 showed potent antimicrobial activity with promising MIC values compared to the positive controls. Moreover, compounds 15 and 22 provide a potent lipid peroxidation (LPO) of the bacterial cell wall. On the other hand, we investigated the anti-proliferative activity of compounds 9–23 against selected human cancerous cell lines of breast (MCF-7), colon (HCT-116), and lung (A549) relative to healthy noncancerous control skin fibroblast cells (BJ-1). The mechanism of their cytotoxic activity has been also examined by immunoassaying the levels of key anti- and pro-apoptotic protein markers. The results of MTT assay revealed that compounds 10, 13, 21, 22 and 23 possessed highly cytotoxic effects. Out of these, three synthesized compounds 13, 21 and 22 showed cytotoxicity with IC50 values (13, IC50 = 62.4 ± 0.128 and 22, IC50 = 91.6 ± 0.112 µM, respectively, on MCF-7), (13, IC50 = 43.5 ± 0.15 and 21, IC50 = 38.5 ± 0.17 µM, respectively, on HCT-116). Cell cycle and apoptosis/necrosis assays demonstrated that compounds 13 and 22 induced S and G2/M phase cell cycle arrest in MCF-7 cells, while only compound 13 had this effect on HCT-116 cells. Furthermore, compound 13 exhibited the greatest potency in inducing apoptosis in both cell lines compared to compounds 21 and 22. Docking studies indicated that compounds 10, 13, 21 and 23 could potentially inhibit enzymes and exert promising antimicrobial effects, as evidenced by their lower binding energies and various types of interactions observed at the active sites of key enzymes such as Sterol 14-demethylase of C. albicans, Dihydropteroate synthase of S. aureus, LasR of P. aeruginosa, Glucosamine-6-phosphate synthase of K. pneumenia and Gyrase B of B. subtilis. Moreover, 13, 21, and 22 demonstrated minimal binding energy and favorable affinity towards the active pocket of anticancer receptor proteins, including CDK2, EGFR, Erα, Topoisomerase II and VEGFFR. Physicochemical properties, drug-likeness, and ADME (absorption, distribution, metabolism, excretion, and toxicity) parameters of the selected compounds were also computed.

Objective(s): Breast cancer is an important women’s malignancy with high cancer-related deaths worldwide. Drug resistance lowers the treatment efficacy in this malignancy. This study aimed to explore the underlying mechanisms of histone deacetylase (HDAC) inhibitor trichostatin A (TSA) to overcome resistance to tamoxifen in breast cancer cells.Materials and Methods: Tamoxifen-resistance in MCF-7 breast cancer cells was simulated. MTT assay was used to detect the cytotoxic effects of HDAC inhibitor and PI3K inhibitor on the cancer cells. Trans-well assay was applied to evaluate the invasion and migration of the treated cancer cells. Flow cytometer assay was also applied to evaluate cell cycle phases in the treated cancer cells. Finally, expression of vascular endothelial growth factor (VEGF), E-cadherin, Vimentin, phosphorylated phosphatidylinositol kinase (p-PI3k), phosphorylated protein kinase B (p-AKT), and phosphorylated mammalian target protein of rapamycin (p-mTOR) was evaluated by western blotting.Results: The obtained results indicated that HDAC inhibitor treatments significantly decreased viability, migration, and invasion in the cancer cells. Furthermore, the frequency of the treated cancer cells significantly increased in the S phase as well as significantly decreasing in the G2/M phase of the cell cycle. Moreover, HDAC inhibitor modified levels of VEGF, E-cadherin, Vimentin, p-PI3k, p-AKT, and p-mTOR proteins. However, HDAC inhibitor combined with PI3K inhibitor exerts more profound effects on the cancer cells as compared to HDAC inhibitor monotherapy.Conclusion: HDAC inhibitors inhibited the survival of breast cancer drug-resistant cells, invasion, migration, and angiogenesis by inhibiting the PI3k/Akt/mTOR signaling pathway.

Abstract Crocin is a carotenoid compound in saffron with anti-cancer properties. However, its therapeutic application is limited by its low absorption, bioavailability, and stability, which can be overcome through nanocarrier delivery systems. This study used surface-modified Nano-crystalline cellulose (NCC) to deliver crocin to cancer cells. NCC modified with CTAB were loaded with crocin and then conjugated with folic acid (NCF-CR-NPs). The synthesized nanoparticles (NPs) were characterized using FTIR, XRD, DLS, and FESEM. The crystallinity index of NCC was 66.64%, higher than microcrystalline cellulose (61.4%). The crocin loading and encapsulation efficiency in NCF-CR-NPs were evaluated. Toxicity testing by MTT assay showed that NCF-CR-NPs had higher toxicity against various cancer cell lines, including colon cancer HT-29 cells (IC50 ~ 11.6 μg/ml), compared to free crocin. Fluorescent staining, flow cytometry, and molecular analysis confirmed that NCF-CR-NPs induced apoptosis in HT-29 cells by increasing p53 and caspase 8 expression. The antioxidant capacity of NCF-CR-NPs was also evaluated using ABTS and DPPH radical scavenging assays. NCF-CR-NPs exhibited high free radical scavenging ability, with an IC50 of ~ 46.5 μg/ml for ABTS. In conclusion, this study demonstrates the potential of NCF-CR-NPs to deliver crocin to cancer cells effectively. The NPs exhibited enhanced anti-cancer and antioxidant activities compared to free crocin, making them a promising nanocarrier system for crocin-based cancer therapy.

However, clinical trial information on these monomers is scarce, resulting in a lack of knowledge regarding the research progress, efficacy, and adverse reactions at the clinical stage. Therefore, this study systematically reviewed the clinical trials on the anti-cancer effect of TCM monomers registered in the Clinicaltrials.gov website before 2023.4.30, paying special attention to the trials on tumors, aiming to explore the research results and development prospects in this field. A total of 1982 trials were started using 69 of the 131 TCM monomers. The number of clinical trials performed each year showed an overall upward trend. However, only 26 monomers entered into 519 interventional anti-tumor trials, with vinblastine (194, 37.38%) and camptothecin (146, 28.13%) being the most used. A total of 45 tumors were studied in these 519 trials, with lymphoma (112, 21.58%) being the most frequently studied. Clinical trials are also unevenly distributed across locations and sponsors/collaborators. The location and the sponsor/collaborator with the highest number of performed trials were the United States (651,32.85%) and NIH (77). Therefore, China and its institutions still have large room for progress in promoting TCM monomers in anti-tumor clinical trials. In the next step, priority should be given to the improvement of the research and development ability of domestic enterprises, universities and other institutions, using modern scientific and technological means to solve the problems of poor water solubility and strong toxic and side effects of monomers, so as to promote the clinical research of TCM monomers.Keywords: traditional Chinese medicine monomers, anti-cancer, interventional clinical trials, research progress, adverse reactions

Fucoxanthin is a carotenoid, reddish-brown in color, which is mainly derived from marine organisms such as brown algae and diatoms, and has aroused extensive scientific interest due to its unique chemical structure and abundant biological activities. Studies have shown that fucoxanthin processes significant anti-inflammatory and anti-cancer activities. Its anti-inflammatory mechanisms primarily include inhibiting oxidative stress, regulating inflammatory factors, inducting cell autophagy, and resisting cell apoptosis, etc. The main mechanism of anti-cancer activity includes inducing cell autophagy and apoptosis mechanisms, regulating the cell cycle, inhibiting cell migration, and suppressing cell invasion, among other aspects. In this paper, the research progress of anti-inflammatory and anti-cancer activities and related mechanisms of action of fucoxanthin is briefly summarized, which provides the theoretical basis and reference for further research and development of fucoxanthin.

Colorectal carcinoma (CRC) is one of the most common malignancies, though there are no effective therapeutic regimens at present. This study aimed to investigate the inhibitory effects of mannooligosaccharides extracted from coconut meal (CMOSs) on the proliferation and migration of human colorectal cancer HCT116 cells in vitro. The results showed that CMOSs exhibited significant inhibitory activity against HCT116 cell proliferation in a concentration-dependent manner with less cytotoxic effects on the Vero normal cells. CMOSs displayed the ability to increase the activation of caspase-8, –9, and –3/7, as well as the generation of reactive oxygen species (ROS). Moreover, CMOSs suppressed HCT116 cell migration in vitro. Interestingly, treatment of human microvascular endothelial cells (HMVECs) with CMOSs resulted in the inhibition of cell proliferation, cell migration, and capillary-like tube formation, suggesting its anti-vascular angiogenesis. In summary, the results of this study indicate that CMOSs could be a valuable therapeutic candidate for CRC treatment.

Background: Several nano formulations of silver nanoparticles with bioconjugates, herbal extracts and anti-cancerous drug coating have been vividly studied to target cancer. Despite of such extensive studies, AgNPs (silver nanoparticles) have not reached the stage of clinical use. Out of all possible reasons for this failure, the unexplored effect on Cancer Stem Cell (CSC) population and mechanism of action of AgNPs, are the most plausible ones and are worked upon in this study. Methods: AgNPs were synthesized by chemical reduction method using sodium citrate and characterized by UV, FTIR, XRD and electron microscopy. CSC population was isolated from Cal33 cell line by MACS technique. MTT assay, trypan blue exclusion assay, Annexin V and PI based apoptosis assay and cell cycle assay were performed. Results: The results showed that synthesized AgNPs have cytotoxic activity on all cancer cell lines tested with the IC50 value of a wide range (1.5–49.21 µg/ml for cell lines and 0.0643–0.1211 µg/ml for splenocytes and thymocytes). CSCs Cal33 showed higher resistance to AgNP treatment and arrest in G1/G0 phase upon cell cycle analysis. Conclusion: AgNPs as an anti-cancer agent although have great potential but is limited by its off-target effects on normal cells and less effective on cancer stem cells at lower concentrations.
