- Abstract
Solid dispersion is a unique and promising approach for improving the oral absorption and oral bioavailability of BCS class II drugs. Modified gum karaya a recently developed excipient was evaluated as a carrier for solubility and dissolution enhancement of poorly water soluble drug atorvastatin calcium. Physical mixtures along with solid dispersions of drug and polymer was prepared using three methods kneading, solvent evaporation and solvent wetting method in 5 different ratios (1:1,1:3,1:5,1:7,1:9). Among the three methods used atorvastatin calcium solid dispersions prepared by kneading method in 1:3 ratio showed most promising results in terms of percent yield, percent drug content, solubility of solid dispersions in phosphate buffer pH 6.8, XRD, DSC, SEM and In vitro release studies. These solid dispersions were selected to prepare tablets using Ac-di-sol as superdisintegrant (T1, T2, T3, T4 and T5). Tablets were characterized for hardness, friability, disintegration time, percent drug content, drug release studies and stability studies. Tablets T5 showed highest dissolution rate and best dissolution efficiency at (DE30) and (DE120) minutes. Release data of T5 tablet was subjected to various release kinetics models to know the type and order of drug release. Order was found to be Korsemeyer–Peppas>Hixson–Crowell cube root law >zero-order >first-order >Higuchi. The similarity factor was calculated for comparison of the dissolution profile before and after stability studies. The f2 value was found to be more than 50 (~ 90.9) thereby indicating a close similarity between both the dissolution profiles. In vivo studies was conducted on healthy albino rats and formulation given by oral route showed that at the end of 14 days solid dispersion 1:3 performed better than pure atorvastatin calcium in reducing total cholesterol and TG level and increasing HDL- cholesterol levels.

- Abstract
Introduction: Autism is a neurodevelopmental disorder associated with mitochondrial dysfunction, apoptosis, and neuroinflammation. These factors can lead to the overactivation of c-JNK and p38MAPK., Methods: In rats, stereotactic intracerebroventricular (ICV) injection of propionic acid (PPA) results in autistic-like characteristics such as poor social interaction, repetitive behaviours, and restricted communication. Research has demonstrated the beneficial effects of phytochemicals derived from plants in treating neurological disorders. Tanshinone-IIA (Tan-IIA) is a chemical found in the root of Salvia miltiorrhiza. It has neuroprotective potential by inhibiting c-JNK and p38MAPK against behavioral and neurochemical alterations in PPA-induced autistic rats. We observe behavioral changes, alterations in apoptotic markers, myelin basic protein (MBP), neurofilament-Light (NEFL), inflammatory cytokines, brain-derived neurotrophic factor (BDNF), and neurotransmitter imbalances using different brain regions (cerebral cortex, hippocampus, striatum), as well as biological samples, cerebrospinal fluid (CSF), and blood plasma., Results: Persistent administration of 30 mg/kg and 60 mg/kg Tan-IIA via intraperitoneal injection reduced these alterations dose-dependently. Anisomycin (3 mg/kg.,i.p.) as a SAPK (c-JNK and p38MAPK) agonist was administered to assess the neuroprotective effect of Tan-IIA in autistic rats. Tan- IIA's molecular interactions with c-JNK and p38MAPK were confirmed using silico analysis. We also observed gross morphological, histopathological, and Luxol Fast Blue (LFB) myelin straining changes in whole and coronal brain sections., Conclusion: Thus, Tan-IIA has a neuroprotective potential by inhibiting the c-JNK and p38MAPK signalling pathways, which reduces the behavioral and neurochemical abnormalities induced by PPA in adult Wistar rats, indicating that current results should be studied further for the diagnosis and treatment of autism., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Background: Cardiac arrhythmia, is a medical condition that reduces the heart's efficiency in pumping blood, and can be fatal, requires long-term management with conventional drugs, despite their limited efficacy. Diltiazem hydrochloride, chosen as a model drug, has a short biological half-life and extensive metabolism. Administering drug through skin is challenging, particularly due to the penetration via stratum corneum. However, solid lipid nanoparticles as a particulate carrier system can enhance its permeation and bioavailability., Objective: The study aimed to develop a matrix type transdermal patch with diltiazem hydrochloride encapsulated in solid lipid nanoparticles Methods: The study used the solvent diffusion technique to prepare SLNs by mixing the drug and solid lipid in an organic phase at 80°C, then slowly adding it to an aqueous phase with continuous stirring for 45 minutes. The resulting nanodispersion was freeze-dried and analyzed for morphological studies, encapsulation efficiency & drug content. A patch was formulated using solvent evaporation technique, incorporating HPMC E50 (2% w/v), propylene glycol, and ethanolic oleic acid (1.5% v/v). SLNs loaded with diltiazem hydrochloride taken equivalent to diltiazem hydrochloride dose in the transdermal patch. The patch was then evaluated for In vitro and skin permeation studies., Results: The result showed a positive correlation between lipid concentration and particle size. Probe sonication and homogenization increased particle size, while stirring speed reduced it. SEM and TEM images confirmed spherical particles with a size of 488.1±4.01nm and an entrapment efficiency of 55.03±1.99%. Drug release studies demonstrated 70.7% drug release from lipid matrix over 24 hrs. The formulated patch with uniform SLN distribution, had a drug content 89.37 ± 0.04% with a surface pH of 6.1 ± 0.53, close to skin pH. The uniformity of content in 3x3 patch estimated to be 14.587 ± 1.404 mg, close to the theoretical content 16.318 ± 1.08 mg, confirmed homogenous distribution of diltiazem hydrochloride SLNs throughout the patch diameter. Cumulative amount released from patch formulation at pH 5.6 and pH 7.4 was 518.1414μg/cm2 and 404.4466 μg/cm2. Synergistic flux enhancement was observed with oleic acid propylene glycol blend. Ex vivo study of the patch showed steady-state flux of 6.9 μg/cm2/hr, permeability coefficient 0.00362 cm/hr, diffusion coefficient 0.000103 cm/hr, cumulative drug permeation (Dmax) 814.885 μg after 24 hrs, and followed a Higuchi-matrix release model., Conclusion: The developed patch possessed improved bioavailability with reduced dosing and enhanced patient compliance., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Neuropathological diseases involve the death of neurons and the aggregation of proteins with altered properties in the brain. Proteins are used at the molecular level to categorize neurodegenerative disorders, emphasizing the importance of protein-processing mechanisms in their development. Natural herbal phytoconstituents, such as icariin, have addressed these neurological complications. Icariin, the principal compound in Epimedium, has been studied for its antineuroinflammatory, anti-oxidative, and antiapoptotic properties. Recent scientific investigations have shown that icariin exhibits promising therapeutic and preventive properties for mental and neurodegenerative disorders. In preclinical, icariin has been shown to inhibit amyloid development and reduce the expression of APP and BACE-1. Previous preclinical studies have demonstrated that icariin can regulate proinflammatory responses in neurological conditions like Parkinson's disease, depression, cerebral ischemia, ALS, and multiple sclerosis. Studies have shown that icariin possesses neuroprotective properties by modulating signaling pathways and crossing the blood-brain barrier, suggesting its potential to address various neurocomplications. This review aims to establish a foundation for future clinical investigations by examining the existing literature on icariin and exploring its potential therapeutic implications in treating neurodegenerative disorders and neuropsychiatric conditions. Future research may address numerous concerns and yield captivating findings with far-reaching implications for various aspects of icariin., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Sharma T, Mehan S, Tiwari A, Khan Z, Gupta GD, and Narula AS
- Abstract
Multiple sclerosis [MS] is a progressive autoimmune condition that primarily affects young people and is characterized by demyelination and neurodegeneration of the central nervous system [CNS]. This in-depth review explores the complex involvement of oligodendrocytes, the primary myelin- producing cells in the CNS, in the pathophysiology of MS. It discusses the biochemical processes and signalling pathways required for oligodendrocytes to function and remain alive, as well as how they might fail and cause demyelination to occur. We investigate developing therapeutic options that target remyelination, a fundamental component of MS treatment. Remyelination approaches promote the survival and differentiation of oligodendrocyte precursor cells [OPCs], restoring myelin sheaths. This improves nerve fibre function and may prevent MS from worsening. We examine crucial parameters influencing remyelination success, such as OPC density, ageing, and signalling pathway regulation [e.g., Retinoid X receptor, LINGO-1, Notch]. The review also examines existing neuroprotective and antiinflammatory medications being studied to see if they can assist oligodendrocytes in surviving and reducing the severity of MS symptoms. The review focuses on medicines that target the myelin metabolism in oligodendrocytes. Altering oligodendrocyte metabolism has been linked to reversing demyelination and improving MS patient outcomes through various mechanisms. We also explore potential breakthroughs, including innovative antisense technologies, deep brain stimulation, and the impact of gut health and exercise on MS development. The article discusses the possibility of personalized medicine in MS therapy, emphasizing the importance of specific medicines based on individual molecular profiles. The study emphasizes the need for reliable biomarkers and improved imaging tools for monitoring disease progression and therapy response. Finally, this review focuses on the importance of oligodendrocytes in MS and the potential for remyelination therapy. It also underlines the importance of continued research to develop more effective treatment regimens, taking into account the complexities of MS pathology and the different factors that influence disease progression and treatment., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Nesmith T, Vieira C, Rackus DG, and Gupta GD
- Abstract
Electric fields are used in biology to address a broad range of questions and through a variety of techniques, including electroporation, gene electrotransfer (GET), electrostimulation (ES), and electrochemotherapy. Each of these modalities requires specific conditions and has drastically different target outcomes on the cell. ES has demonstrated that non-pore forming electric fields alter cell cycle progression. However, pore forming electric fields such as with GET have not been as widely explored despite major clinical advancements. Additionally, the real-time visual analysis of electrical field effects on mammalian cell culture is currently lacking among most commercial systems. To facilitate investigations into these research areas, an electroporation cytometry system was developed including a custom chamber compatible with live cell imaging and exponential decay pulse generator for live cell analysis. The functionality of the system was demonstrated using a recombinant cell line using U-2 OS cells and FUCCI(CA)5 cell cycle reporter. The exposure of the cells to a 180 V pulse in both unsynchronized and synchronized populations revealed an effect on the cell cycle., Competing Interests: D.G.R. is on the Scientific Advisory Board for World Precision Instruments, Inc., for which he receives compensation.

- Abstract
The Nucleocapsid (N) protein of SARS-CoV-2 plays a crucial role in viral replication and pathogenesis, making it an attractive target for developing antiviral therapeutics. In this study, we used differential scanning fluorimetry to establish a high-throughput screening method for identifying high-affinity ligands of N-terminal domain of the N protein (N-NTD). We screened an FDA-approved drug library of 1813 compounds and identified 102 compounds interacting with N-NTD. The screened compounds were further investigated for their ability to inhibit the nucleic-acid binding activity of the N protein using electrophoretic mobility-shift assays. We have identified three inhibitors, Ceftazidime, Sennoside A, and Tannic acid, that disrupt the N protein's interaction with RNA probe. Ceftazidime and Sennoside A exhibited nano-molar range binding affinities with N protein, determined through surface plasmon resonance. The binding sites of Ceftazidime and Sennoside A were investigated using [
1 H,15 N]-heteronuclear single quantum coherence (HSQC) NMR spectroscopy. Ceftazidime and Sennoside A bind to the putative RNA binding site of the N protein, thus providing insights into the inhibitory mechanism of these compounds. These findings will contribute to the development of novel antiviral agents targeting the N protein of SARS-CoV-2., Competing Interests: Declaration of competing interest None., (Copyright © 2024.

- Abstract
Multiple sclerosis (MS), a prevalent neurological disorder, predominantly affects young adults and is characterized by chronic autoimmune activity. The study explores the immune system dysregulation in MS, highlighting the crucial roles of immune and non-neuronal cells in the disease's progression. This review examines the dual role of cytokines, with some like IL-6, TNF-α, and interferon-gamma (IFN-γ) promoting inflammation and CNS tissue injury, and others such as IL-4, IL-10, IL-37, and TGF-β fostering remyelination and protecting against MS. Elevated chemokine levels in the cerebrospinal fluid (CSF), including CCL2, CCL5, CXCL10, CXCL13, and fractalkine, are analyzed for their role in facilitating immune cell migration across the blood-brain barrier (BBB), worsening inflammation and neurodegeneration. The study also delves into the impact of auto-antibodies targeting myelin components like MOG and AQP4, which activate complement cascades leading to further myelin destruction. The article discusses how compromised BBB integrity allows immune cells and inflammatory mediators to infiltrate the CNS, intensifying MS symptoms. It also examines the involvement of astrocytes, microglia, and oligodendrocytes in the disease's progression. Additionally, the effectiveness of immunomodulatory drugs such as IFN-β and CD20-targeting monoclonal antibodies (e.g., rituximab) in modulating immune responses is reviewed, highlighting their potential to reduce relapse rates and delaying MS progression. These insights emphasize the importance of immune system dysfunction in MS development and progression, guiding the development of new therapeutic strategies. The study underscores recent advancements in understanding MS's molecular pathways, opening avenues for more targeted and effective treatments., (Copyright © 2024 IBRO. Published by Elsevier Inc.

- Abstract
Aptamers, a novel type of targeted ligand used in drug delivery, have quickly gained popularity due to their high target specificity and affinity. Different aptamer-mediated drug delivery systems, such as aptamer-drug conjugate (ApDC), aptamer-siRNA, and aptamer-functionalised nanoparticle systems, are currently being developed for the successful treatment of cancer based on the excellent properties of aptamers. These systems can decrease potential toxicity and enhance therapeutic efficacy by targeting the drug moiety. In this review, we provide an overview of recent developments in aptamer-mediated delivery systems for cancer therapy, specifically for breast cancer, and talk about the potential applications and current issues of novel aptamer-based techniques. This study in aptamer technology for breast cancer therapy highlights key aptamers targeting well-established biomarkers such as HER2, oestrogen receptor, and progesterone receptor. Additionally, we explore the potential of aptamers in overcoming various challenges such as drug resistance and improving the delivery of therapeutic agents. This review aims to provide a deeper understanding of the present aptamer-based targeted delivery applications through in-depth analysis to increase efficacy and create new therapeutic approaches that may ultimately lead to better treatment outcomes for cancer patients.

- Abstract
The purpose of this study was to enhance the topical delivery of 5-Fluorouracil (5-FU), a cancer treatment, by developing a nanoemulgel formulation. Glycyrrhizin (GLY), a natural penetration enhancer has been investigated to exhibit synergistic effects with 5-FU in inhibiting melanoma cell proliferation and inducing apoptosis, Hence, GLY, along with suitable lipids was utilized to create an optimized nanoemulsion (NE) based gel. Solubility studies and ternary phase diagram revealed isopropyl myristate (IPM), Span 80, Tween 80 as S
mix and Transcutol P as co-surfactant. IPM demonstrates excellent solubilizing properties facilitates higher drug loading, ensuring efficient delivery to the target site.,The optimized formulation consisting of 40 % IPM, 30 % of mixture of Tween80: Span80 (Smix ) and 15 % Transcutol P provides with a nanometric size of 64.1 ± 5.13 nm and drug loading of 97.3 ± 5.83 %. The optimized formulation observed with no creaming and breakeing of NE and found thermodynamically stable during different stress conditions (temperatures of 4.0 °C and 45.0 °C) and physical thawing (-21.0 ± 0.50 °C to 20.0 ± 0.50 °C). The NE was then transformed into a nanoemulgel (NEG) using 1.5 % w/w Carbopol base and 0.1 % w/w glycyrrhizin. The ex vivo permeability studies showed significant enhancements in drug permeability with the GLY-based 5-FU-NEG formulation compared to pure 5-FU gel in excised pig skin upto1440 min in PBS 7.4 as receptor media.

- Abstract
Fyn, Blk, and Lyn are part of a group of proteins called Src family kinases. They are crucial in controlling cell communication and their response to the growth, changes, and immune system. Blocking these proteins with inhibitors can be a way to treat diseases where these proteins are too active. The primary mode of action of these inhibitors is to inhibit the phosphorylation of Fyn, Blk, and Lyn receptors, which in turn affects how signals pass within the cells. This review shows the structural and functional aspects of Fyn, Blk, and Lyn kinases, highlighting the significance of their dysregulation in diseases such as cancer and autoimmune disorders. The discussion encompasses the design strategies, SAR analysis, and chemical characteristics of effective inhibitors, shedding light on their specificity and potency. Furthermore, it explores the progress of clinical trials of these inhibitors, emphasizing their potential therapeutic applications., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
Cancer stands as one of the deadliest diseases, ranking second in terms of its global impact. Despite the presence of numerous compelling theories concerning its origins, none have succeeded in fully elucidating the intricate nature of this ailment. Among the prevailing concerns in today's world, breast cancer proliferation remains a significant issue, particularly affecting females. The abnormal proliferation of the PI3K pathway emerges as a prominent driver of breast cancer, underscoring its role in cellular survival and proliferation. Consequently, targeting this pathway has emerged as a leading strategy in breast cancer therapeutics. Within this context, the present article explores the current landscape of anti-tumour drug development, focusing on structural activity relationships (SAR) in PI3K targeting breast cancer treatment. Notably, certain moieties like triazines, pyrimidine, quinazoline, quinoline, and pyridoxine have been explored as potential PI3K inhibitors for combating breast cancer. Various heterocyclic small molecules are undergoing clinical trials, such as Alpelisib, the first orally available FDA-approved drug targeting PI3K; others include buparlisib, pictilisib, and taselisib, which inhibit class I PI3K. These drugs are used for the treatment of breast cancer but still have various side effects with their high cost. Therefore, the primary goal of this review is to include all current advances in the development of anticancer medicines that target PI3K over-activation in the treatment of breast cancer., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr Vivek Asati reports was provided by ISF College of Pharmacy.

- Abstract
Cancer is indeed considered a hazardous and potentially life-threatening disorder. The JAK/STAT pathway is an important intracellular signaling cascade essential for many physiological functions, such as immune response, cell proliferation, and differentiation. Dysregulation of this pathway aids in the progression and development of cancer. The downstream JAK2/STAT3 signaling cascades are legitimate targets against which newer anticancer drugs can be developed to prevent and treat cancer. Understanding the mechanisms behind JAK2/STAT3 participation in cancer has paved the way for developing innovative targeted medicines with the potential to improve cancer treatment outcomes. This article provides information on the current scenario and recent advancements in the design and development of anticancer drugs targeting JAK2/STAT3, including structural analysis and SAR investigations of synthesized molecules. Numerous preclinical and clinical trials are ongoing on these inhibitors, which are highlighted to gain more insight into the broader development prospects of inhibitors of JAK2/STAT3., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

- Abstract
It is now well understood that many signaling pathways are vital in carrying out and controlling essential pro-survival and pro-growth cellular functions. The NOTCH signaling pathway, a highly conserved evolutionary signaling pathway, has been thoroughly studied since the discovery of NOTCH phenotypes about 100 years ago in Drosophila melanogaster . Abnormal NOTCH signaling has been linked to the pathophysiology of several diseases, notably cancer. In tumorigenesis, NOTCH plays the role of a "double-edged sword," that is, it may act as an oncogene or as a tumor suppressor gene depending on the nature of the context. However, its involvement in several cancers and inhibition of the same provides targeted therapy for the management of cancer. The use of gamma (γ)-secretase inhibitors and monoclonal antibodies for cancer treatment involved NOTCH receptors inhibition, leading to the possibility of a targeted approach for cancer treatment. Likewise, several natural compounds, including curcumin, resveratrol, diallyl sulfide, and genistein, also play a dynamic role in the management of cancer by inhibition of NOTCH receptors. This review outlines the functions and structure of NOTCH receptors and their associated ligands with the mechanism of the signaling pathway. In addition, it also emphasizes the role of NOTCH-targeted nanomedicine in various cancer treatment strategies.

38. Icariin prevents methylmercury-induced experimental neurotoxicity: Evidence from cerebrospinal fluid, blood plasma, brain samples, and in-silico investigations.
- Author

Sharma S, Mehan S, Khan Z, Gupta GD, and Narula AS
- Abstract
Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease that causes significant neurodegeneration. Methylmercury (MeHg+) is a neurotoxin that induces axonal neurodegeneration and motor nerve degeneration by destroying oligodendrocytes, degenerating white matter, inducing apoptosis, excitotoxicity, and reducing myelin basic protein (MBP). This study examines the inhibition of SIRT-1 (silence information regulator 1), Nrf-2 (nuclear factor E2-related factor 2), HO-1 (heme oxygenase 1), and TDP-43 (TAR-DNA-binding protein 43) accumulation in the context of ALS, as well as the modulation of these proteins by icariin (15 and 30 mg/kg, orally), a glycoside flavonoid with neuroprotective properties. Neuroprotective icariin activates SIRT-1, Nrf-2, and HO-1, mitigating inflammation and neuronal injury in neurodegenerative disorders. In-vivo and in-silico testing of experimental ALS models confirmed icariin efficacy in modulating these cellular targets. The addition of sirtinol 10 mg/kg, an inhibitor of SIRT-1, helps determine the effectiveness of icariin. In this study, we also examined neurobehavioral, neurochemical, histopathological, and LFB (Luxol fast blue) markers in various biological samples, including Cerebrospinal fluid (CSF), blood plasma, and brain homogenates (Cerebral Cortex, Hippocampus, Striatum, mid-brain, and Cerebellum). These results demonstrate that the administration of icariin ameliorates experimental ALS and that the mechanism underlying these benefits is likely related to regulating the SIRT-1, Nrf-2, and HO-1 signaling pathways., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Author(s).)

- Abstract
Magnesium (Mg
2+ ) is a crucial mineral involved in numerous cellular processes critical for neuronal health and function. This review explores the multifaceted roles of Mg2+ , from its biochemical interactions at the cellular level to its impact on cognitive health and behavioral regulation. Mg2+ acts as a cofactor for over 300 enzymatic reactions, including those involved in ATP synthesis, nucleic acid stability, and neurotransmitter release. It regulates ion channels, modulates synaptic plasticity, and maintains the structural integrity of cell membranes, which are essential for proper neuronal signaling and synaptic transmission. Recent studies have highlighted the significance of Mg2+ in neuroprotection, showing its ability to attenuate oxidative stress, reduce inflammation, and mitigate excitotoxicity, thereby safeguarding neuronal health. Furthermore, Mg2+ deficiency has been linked to a range of neuropsychiatric disorders, including depression, anxiety, and cognitive decline. Supplementation with Mg2+ , particularly in the form of bioavailable compounds such as Magnesium-L-Threonate (MgLT), Magnesium-Acetyl-Taurate (MgAT), and other Magnesium salts, has shown some promising results in enhancing synaptic density, improving memory function, and alleviating symptoms of mental health disorders. This review highlights significant current findings on the cellular mechanisms by which Mg2+ exerts its neuroprotective effects and evaluates clinical and preclinical evidence supporting its therapeutic potential. By elucidating the comprehensive role of Mg2+ in neuronal health, this review aims to underscore the importance of maintaining optimal Mg2+ levels for cognitive function and behavioral regulation, advocating for further research into Mg2+ supplementation as a viable intervention for neuropsychiatric and neurodegenerative conditions., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)- Published

- Abstract
Cardiovascular complications and renal disease is the growing cause of mortality in patients with diabetes. The subversive complications of diabetes such as hyperglycemia, hyperlipidemia and insulin resistance lead to an increase in the risk of myocardial infarction (MI), stroke, heart failure (HF) as well as chronic kidney disease (CKD). Among the commercially available anti-hyperglycemic agents, incretin-based medications appear to be safe and effective in the treatment of type 2 diabetes mellitus (T2DM) and associated cardiovascular and renal disease. Glucagon-like peptide 1 receptor agonists (GLP-1RAs) have been shown to be fruitful in reducing HbA1c, blood glucose, lipid profile, and body weight in diabetic patients. Several preclinical and clinical studies revealed the safety, efficacy, and preventive advantages of GLP-1RAs against diabetes- induced cardiovascular and kidney disease. Data from cardio-renal outcome trials had highlighted that GLP-1RAs protected people with established CKD from significant cardiovascular disease, lowered the likelihood of hospitalization for heart failure (HHF), and lowered all-cause mortality. They also had a positive effect on people with end-stage renal disease (ESRD) and CKD. Beside clinical outcomes, GLP-1RAs reduced oxidative stress, inflammation, fibrosis, and improved lipid profile pre-clinically in diabetic models of cardiomyopathy and nephropathy that demonstrated the cardio-protective and reno-protective effect of GLP-1RAs. In this review, we have focused on the recent clinical and preclinical outcomes of GLP-1RAs as cardio-protective and reno-protective agents as GLP-1RAs medications have been demonstrated to be more effective in treating T2DM and diabetes-induced cardiovascular and renal disease than currently available treatments in clinics, without inducing hypoglycemia or weight gain., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Neuroblastoma, the most common childhood solid tumor, originates from primitive sympathetic nervous system cells. Epoxyazadiradione (EAD) is a limonoid derived from Azadirachta indica , belonging to the family Meliaceae. In this study, we isolated the EAD from Azadirachta indica seed and studied the anti-cancer potential against neuroblastoma. Herein, EAD demonstrated significant efficacy against neuroblastoma by suppressing cell proliferation, enhancing the rate of apoptosis and cycle arrest at the SubG
0 and G2 /M phases. EAD enhanced the pro-apoptotic Caspase 3 and Caspase 9 and inhibited the NF-kβ translocation in a dose-dependent manner. In order to identify the specific EAD target, a gel-free quantitative proteomics study on SH-SY5Y cells using Liquid Chromatography with tandem mass spectrometry was done in a dose-dependent manner, followed by detailed bioinformatics analysis to identify effects on protein. Proteomics data identified that Enolase1 and HSP90 were up-regulated in neuroblastoma. EAD inhibited the expression of Enolase1 and HSP90, validated by mRNA expression, immunoblotting, Enolase1 and HSP90 kit and flow-cytometry based bioassay. Molecular docking study, Molecular dynamic simulation, and along with molecular mechanics/Poisson-Boltzmann surface area analysis also suggested that EAD binds at the active site of the proteins and were stable throughout the 100 ns Molecular dynamic simulation study. Overall, this study suggested EAD exhibited anti-cancer activity against neuroblastoma by targeting Enolase1 and HSP90 pathways.Communicated by Ramaswamy H. Sarma.- Published

- Abstract
The primary cilium is a highly conserved microtubule-based organelle present in most vertebrate cell types. Mutations in ciliary protein genes can lead to dysfunctional or absent cilia and are the cause of a large group of heterogeneous diseases known as ciliopathies. ARL13B is a member of the ARF family of regulatory GTPases and is highly enriched on the ciliary membrane. The absence of ARL13B disrupts cilia architecture and mutations have been linked to several diseases; yet there remain major gaps in our understanding of the role that ARL13B plays in primary cilia function. Here, we demonstrate how in cellulo proximity-dependent biotinylation (BioID) can be used to generate a comprehensive protein proximity map of ciliary proteins by performing BioID on N- and C-terminally BirA*-tagged ARL13B. This method can theoretically provide insight into any cilia protein, identifying key interactors that play a critical role in ciliary biology., (© 2024.

- Abstract
The development of an efficient and innovative drug delivery system is essential to improve the pharmacological parameters of the medicinal compound or drug. The technique or manner used to improve the pharmacological parameters plays a crucial role in the delivery system. In the current scenario, various drug delivery systems are available where nanotechnology has firmly established itself in the field of drug delivery. One of the most prevalent elements is carbon with its allotropic modifications such as graphene-based nanomaterials, carbon nanotubes, carbon dots, and carbon fullerenes, these nanomaterials offer notable physiochemical and biochemical properties for the delivery applications due to their smaller size, surface area, and ability to interact with the cells or tissues. The exceptional physicochemical properties of carbon-based 2D nanomaterials, such as graphene and carbon nanotubes, make them attractive candidates for drug delivery systems. These nanomaterials offer a large surface area, high drug loading capacity, and tunable surface chemistry, enabling efficient encapsulation, controlled release, and targeted delivery of therapeutic agents. These properties of the nanomaterials can be exploited for drug delivery applications, like assisting the target delivery of drugs and aiding combination molecular imaging. This review emphasizes on the recent patents on 2D carbon-based nanomaterial and their role in drug delivery systems. Carbon-based 2D nanomaterials present a wealth of opportunities for advanced drug delivery systems. Their exceptional properties and versatility offers great potential in improving therapeutic efficacy, minimizing side effects, and enabling personalized medicine and the recent patents on 2D nanomaterial., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Dementia, an international health issue distinguished by the impairment of daily functioning due to cognitive decline, currently affects more than 55 million people worldwide, with the majority residing in low-income and middle-income countries. Globally, dementia entails significant economic burdens in 2019, amounting to a cost of 1.3 trillion US dollars. Informal caregivers devote considerable hours to providing care for those affected. Dementia imposes a greater caregiving and disability-adjusted life-year burden on women. A recent study has established a correlation between prolonged Proton Pump Inhibitor (PPI) usage and dementia, in addition to other neurodegenerative conditions. PPIs are frequently prescribed to treat peptic ulcers and GERD (gastroesophageal reflux disease) by decreasing stomach acid secretion. They alleviate acid-related symptoms through the inhibition of acid-secreting H
+ -K+ ATPase. In a number of observational studies, cognitive decline and dementia in the elderly have been linked to the use of PPIs. The precise mechanism underlying this relationship is unknown. These drugs might also alter the pH of brain cells, resulting in the accumulation of amyloid-beta (Aβ) peptides and the development of Alzheimer's disease (AD). Despite the compelling evidence supporting the association of PPIs with dementia, the results of studies remain inconsistent. The absence of a correlation between PPI use and cognitive decline in some studies emphasizes the need for additional research. Chronic PPI use can conceal underlying conditions, including cancer, celiac disease, vitamin B12 deficiency, and renal injury, highlighting dementia risk and the need for further investigations on cognitive health., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)- Published

- Abstract
Triple-negative breast cancer (TNBC), a subtype of breast cancer that lacks expression of oestrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2), has clinical features including a high degree of invasiveness, an elevated risk of metastasis, tendency to relapse, and poor prognosis. It constitutes around 10-15% of all breast cancer, and having heredity of BRCA1 mutated breast cancer could be a reason for the occurrence of TNBC in women. Overexpression of cellular and molecular targets, i.e. CD44 receptor, EGFR receptor, Folate receptor, Transferrin receptor, VEGF receptor, and Androgen receptor, have emerged as promising targets for treating TNBC. Signalling pathways such as Notch signalling and PI3K/AKT/mTOR also play a significant role in carrying out and managing crucial pro-survival and pro-growth cellular processes that can be utilised for targeted therapy against triple-negative breast cancer. This review sheds light on various targeting strategies, including cellular and molecular targets, signalling pathways, poly (ADP-ribose) polymerase inhibitors, antibody-drug conjugates, and immune checkpoint inhibitors PARP, immunotherapy, ADCs have all found a place in the current TNBC therapeutic paradigm. The role of photothermal therapy (PTT) and photodynamic therapy (PDT) has also been explored briefly.

- Abstract
Mutations in the unique ATP-binding cassette anion channel, the cystic fibrosis conductance regulator (CFTR), lead to the inherited fatal disease known as cystic fibrosis (CF). Ivacaftor enhances channel gating of CFTR by stabilizing its open state and has been approved as monotherapy for CF patients with CFTR gating mutations (e.g., G551D) and as part of combination therapy with lumacaftor for CFTR folding mutations (e.g., ΔF508). However, in the latter context, ivacaftor may destabilize folding-rescued ΔF508-CFTR and membrane-associated proteins and attenuate lumacaftor pharmacotherapy. Here, we tested the hypothesis that the high lipophilicity of ivacaftor may contribute to this effect. We describe the synthesis of three glutamic acid ivacaftor derivatives with reduced lipophilicity that bear different charges at neutral pH (compounds 2 , 3 , 4 ). In a cellular ion flux assay, all three restored G551D-CFTR channel activity at comparable or better levels than ivacaftor. Furthermore, unlike ivacaftor, compound 3 did not attenuate levels of folding-rescued ΔF508 at the cell surface. Molecular modeling predicts that the increased polarity of compound 3 allows engagement with polar amino acids present in the binding pocket with hydrogen bonding and ionic interactions, which are collectively higher in strength as compared to hydrophobic interactions that stabilize ivacaftor. Overall, the data suggests that reduced lipophilicity may improve the efficacy of this class of CFTR potentiators when used for folding-rescued ΔF508-CFTR., Competing Interests: The authors declare no competing financial interest., (© 2023 The Authors.
