- Abstract
Piceatannol is a naturally occurring hydroxylated resveratrol analogue that can be found in a variety of fruits and vegetables. It has been documented to have a wide range of beneficial effects, including anti-inflammatory, antioxidant, anti-aging, anti-allergic, antidiabetic, neuroprotective, cardioprotective, and chemopreventive properties. Piceatannol has significantly higher antioxidant activity than resveratrol. Piceatannol has been shown in preclinical studies to have the ability to inhibit or reduce the growth of cancers in various organs such as the brain, breast, lung, colon, cervical, liver, prostate, and skin. However, the bioavailability of Piceatannol is comparatively lower than resveratrol and other stilbenes. Several approaches have been reported in recent years to enhance its bioavailability and biological activity, and clinical trials are required to validate these findings. This review focuses on several aspects of natural stilbene Piceatannol, its chemistry, and its mechanism of action, and its promising therapeutic potential for the prevention and treatment of a wide variety of complex human diseases.

- Abstract
The vagina is an essential part of the female reproductive system and offers many potential benefits over conventional drug delivery including a large surface area for drug absorption, relatively low enzymatic activity, avoids first-pass effects, and ease of administration. The vaginal mucosal cavity is an effective route for administering therapeutic agents that are intended both for local and systemic administration. The present review provides a comprehensive overview of recent trends and developments in vaginal drug delivery. Marketed formulations and products under clinical study are also reviewed. Various novel vaginal delivery systems have been studied in recent years as an effective tool for delivering a range of therapeutic agents to the vagina. These systems offer numerous benefits, including sustained delivery, improved bioavailability, effective permeation, and higher efficacy. The recent focus of the scientific community is on the development of safe and efficient drug delivery systems such as nanoparticles, microparticles, vesicular systems, vaginal rings, microneedles, etc. for vaginal application. Various factors such as the physicochemical properties of the drugs, the volume and composition of the vaginal fluid, the pH of the vaginal fluid, the thickness of the vaginal epithelium, and the influence of sexual intercourse may influence the release of drugs from the delivery system and subsequent absorption from the vaginal route. To date, only limited number of in vivo studies on novel vaginal DDS have been reported. Additionally, drug release kinetics under varying vaginal environments is also not well understood. More research is needed to ensure the suitability, biocompatibility, and therapeutic effectiveness of novel DDS for vaginal delivery. Although numerous strategies and interventions have been developed, clinical translation of these systems remains a challenge. The toxicity of the carrier system is also an important consideration for future

0601 Biochemistry and Cell Biology ,Toxicology - Abstract
Cancer continues to be one of the most challenging diseases to be treated and is one of the leading causes of deaths around the globe. Cancers account for 13% of all deaths each year, with cancer-related mortality expected to rise to 13.1 million by the year 2030. Although, we now have a large library of chemotherapeutic agents, the problem of non-selectivity remains the biggest drawback, as these substances are toxic not only to cancerous cells, but also to other healthy cells in the body. The limitations with chemotherapy and radiation have led to the discovery and development of novel strategies for safe and effective treatment strategies to manage the menace of cancer. Researchers have long justified and have shed light on the emergence of nanotechnology as a potential area for cancer therapy and diagnostics, whereby, nanomaterials are used primarily as nanocarriers or as delivery agents for anticancer drugs due to their tumor targeting properties. Furthermore, nanocarriers loaded with chemotherapeutic agents also overcome biological barriers such as renal and hepatic clearances, thus improving therapeutic efficacy with lowered morbidity. Theranostics, which is the combination of rationally designed nanomaterials with cancer-targeting moieties, along with protective polymers and imaging agents has become one of the core keywords in cancer research. In this review, we have highlighted the potential of various nanomaterials for their application in cancer therapy and imaging, including their current state and clinical prospects. Theranostics has successfully paved a path to a new era of drug design and development, in which nanomaterials and imaging contribute to a large variety of cancer therapies and provide a promising future in the effective management of various cancers. However, in order to meet the therapeutic needs, theranostic nanomaterials must be designed in such a way, that take into account the pharmacokinetic and pharmacodynamics properties of the drug for the development of effective carcinogenic therapy.

Pharmacology & Pharmacy ,1115 Pharmacology and Pharmaceutical Sciences - Abstract
Majority of the representative drugs customarily interact with multiple targets manifesting unintended side effects. In addition, drug resistance and over expression of the cellular efflux-pumps render certain classes of drugs ineffective. With only a few innovative formulations in development, it is necessary to identify pharmacophores and novel strategies for creating new drugs. The conjugation of dissimilar pharmacophoric moieties to design hybrid molecules with an attractive therapeutic profile is an emerging paradigm in the contemporary drug development regime. The recent decade witnessed the remarkable biological potential of 1,3,5-triazine framework in the development of various chemotherapeutics. The appending of the 1,3,5-triazine nucleus to biologically relevant moieties has delivered exciting results. The present review focuses on 1,3,5-triazine based hybrid molecules in the development of pharmaceuticals.

- Abstract
© 2020 Elsevier B.V. From nanopharmaceutics to renewable energy, silver nanoparticles (AgNPs) present innumerable applications in the contemporary era. However, the associated toxicity to the biosystems limits their application. Effective utilization of AgNPs, therefore, requires their surface conjugation with biologically benevolent moieties that enhance the bio-acceptability of silver-based nanosystems, and supplementary functionalities for further extension of their unique applications. The clinical importance of AgNPs was established long ago, but their clinical utilization has been explored only recently with the phenomenon of bio-conjugation. The biomolecule-conjugated AgNPs present operable solutions for tedious clinical complications of the present era, such as multidrug resistance, designing of pharmaceuticals with improved bioavailability, superior drug delivery vehicles and in situ bio imaging of important metabolites that utilize the biomolecule-anchored surface engineered AgNPs. This review epigrammatically discusses some interesting clinical applications of surface conjugated AgNPs with biomolecules such as peptides, nucleic acids, amino acids and antibodies in the current nanopharmaceutical paradigm.

- Abstract
Ganoderma lucidium extract powder (GLEP) contains various polysaccharides which are well known for their antioxidant and anti-inflammatory actions. Probiotics (PB) are well-established for providing a plethora of health benefits. Hence, use of mushroom polysaccharides and probiotics as carriers to solidify liquisolid formulation is anticipated to function as functional excipients i.e. as adsorbent that may provide therapeutic benefits. Quercetin (QUR) has been used as model lipophilic drug in this study. QUR loaded liquisolid compacts (LSCs) were formulated using Tween 80 as solvent. These were further solidified using a combination of PB and GLEP as carriers. Aerosil-200 (A-200) was used as coating agent. The formulation exhibited very good flow characteristics. Dissolution rate of raw QUR was found to be less than 10% in 60 min while in case of QUR loaded LSCs, more than 90% drug release was observed within 5 min. Absence of crystalline peaks of QUR in the DSC and PXRD reports of LSCs and their porous appearance in SEM micrographs indicate that QUR was successfully incorporated in the LSCs. The developed formulation was found to be stable on storage under accelerated stability conditions.

- Abstract
In patients with acute kidney injury progressively converting into chronic kidney disease (CKD), proteinuria and high blood pressure predict progression to end-stage renal disease (ESRD). Although, Renin-angiotensin-aldosterone system (RAAS) regulates blood pressure and kidney disease through both direct and indirect mechanisms. RAAS blockers that act at the level of angiotensin or lower in the cascade can cause compensatory increases in the plasma renin and angiotensin II level. Here, in this review article, we are exploring the evidence-based on RAAS blockade action releases of aldosterone and hypothesizing the molecular mechanism for converting the acute kidney injury into chronic kidney disease to end-stage renal disease.

- Abstract
Over the past two decades, polymersomes have been widely investigated for the delivery of diagnostic and therapeutic agents in cancer therapy. Polymersomes are stable polymeric vesicles, which are prepared using amphiphilic block polymers of different molecular weights. The use of high molecular weight amphiphilic copolymers allows for possible manipulation of membrane characteristics, which in turn enhances the efficiency of drug delivery. Polymersomes are more stable in comparison with liposomes and show less toxicity in vivo. Furthermore, their ability to encapsulate both hydrophilic and hydrophobic drugs, significant biocompatibility, robustness, high colloidal stability, and simple methods for ligands conjugation make polymersomes a promising candidate for therapeutic drug delivery in cancer therapy. This review is focused on current development in the application of polymersomes for cancer therapy and diagnosis. Graphical abstract.

- Abstract
Peutz-Jeghers syndrome (PJS) is a well-described inherited syndrome, characterized by the development of gastrointestinal polyps and characteristic mucocutaneous freckling. PJS is an autosomal prevailing disease, due to genetic mutation on chromosome 19p, manifested by restricted mucocutaneous melanosis in association with gastrointestinal (GI) polyposis. The gene for PJS has recently been shown to be a serine/threonine kinase, known as LKB1 or STK11, which maps to chromosome subband 19p13.3. This gene has a putative coding region of 1302 bp, divided into nine exons, and acts as a tumor suppressor in the hamartomatous polyps of PJS patients and in the other neoplasms that develop in PJS patients. It is probable that these neoplasms develop from hamartomas, but it remains possible that the LKB1 or STK11 locus plays a role in a different genetic pathway of tumor growth in the cancers of PJS patients. This article focuses on the role of LKB1 or STK11 gene expression in PJS and related cancers.

- Abstract
Piceatannol is a naturally occurring hydroxylated resveratrol analogue that can be found in a variety of fruits and vegetables. It has been documented to have a wide range of beneficial effects, including anti-inflammatory, antioxidant, anti-aging, anti-allergic, antidiabetic, neuroprotective, cardioprotective, and chemopreventive properties. Piceatannol has significantly higher antioxidant activity than resveratrol. Piceatannol has been shown in preclinical studies to have the ability to inhibit or reduce the growth of cancers in various organs such as the brain, breast, lung, colon, cervical, liver, prostate, and skin. However, the bioavailability of Piceatannol is comparatively lower than resveratrol and other stilbenes. Several approaches have been reported in recent years to enhance its bioavailability and biological activity, and clinical trials are required to validate these findings. This review focuses on several aspects of natural stilbene Piceatannol, its chemistry, and its mechanism of action, and its promising therapeutic potential for the prevention and treatment of a wide variety of complex human diseases., (© 2023 International Union of Biochemistry and Molecular Biology.)

- Abstract
Many of the infectious diseases are ubiquitous in nature and pose a threat to global and public health. The original cause for such type of serious maladies can be summarized as the scarcity of appropriate analysis and treatment methods. Pulmonary diseases are considered one of the life-threatening lung diseases that affect millions of people globally. It consists of several types, namely, asthma, lung cancer, tuberculosis, chronic obstructive pulmonary disease, and several respiratory-related infections. This is due to the limited access to well-equipped healthcare facilities for early disease diagnosis. This needs the availability of processes and technologies that can help to stop this harmful disease-diagnosing practice. Various approaches for diagnosing various lung diseases have been developed over time, namely, autopsy, chest X-rays, low-dose CT scans, and so forth. The need of the hour is to develop a rapid, simple, portable, and low-cost method for the diagnosis of pulmonary diseases. So nowadays, biosensors have been becoming one of the highest priority research areas as a potentially useful tool for the early diagnosis and detection of many pulmonary lung diseases. In this review article, various types of biosensors and their applications in the diagnosis of lung-related disorders are expansively explained., (© 2023 Wiley Periodicals LLC.)

- Abstract
One of the most prevalent cancers affecting women globally is cervical cancer. Cervical cancer is thought to cause 570 000 new cases annually, and standard treatments can have serious side effects. In this work, the main aim is to design, fabrication, and evaluation of carboplatin loaded chitosan coated liposomal formulation (CCLF-I) for vaginal delivery in the treatment of cervical cancer. The particle size and polydispersity index of the CCLF-1 were observed at 269.33 ± 1.15 and 0.40 ± 0.002 nm, respectively. The in vitro mucin binding studies showed good adhesiveness of CCLF-I as compared to plain liposomes (CPLF-I), which was found at 23.49 and 10.80%, respectively. The ex-vivo percent drug permeation from plain liposomal formulation (CPLF-I) was found to be higher in comparison to chitosan coated liposomal formulation which was 56.33% while in CCLF-I it was observed 47.32% this is due to, higher retainability of delivery system (CCLF-I) on targeted site attained by coating of mucoadhesive polymer on liposomes. Ex vivo tissue retention studies exhibited 24.2% of CCLF-I in comparison to 10.34% from plain drug formulation (CPLF-I). The in vivo vaginal retention studies exhibited 14% of drug retention after 24 h from the novel formulation in comparison to 6% from the plain formulation. The developed CCLF-I formulation would open a new avenue in the cervical treatment.

- Abstract
Carbon dots (CDs), which have particle size of less than 10 nm, are carbon-based nanomaterials that are used in a wide range of applications in the area of novel drug delivery in cancer, ocular diseases, infectious diseases, and brain disorders. CDs are biocompatible, eco-friendly, easy to synthesize, and less toxic with excellent chemical inertness, which makes them very good nanocarrier system to deliver multi-functional drugs effectively. A huge number of researchers worldwide are working on CDs-based drug delivery systems to evaluate their versatility and efficacy in the field of pharmaceuticals. As a result, there is a tremendous increase in our understanding of the physicochemical properties, diagnostic and drug delivery aspects of CDs, which consequently has led us to design and develop CDs-based theranostic system for the treatment of multiple disorders. In this review, we aim to summarize the advances in application of CDs as nanocarrier including gene delivery, vaccine delivery and antiviral delivery, that has been carried out in the last 5 years., Competing Interests: Author AB was employed by Perrigo Company Plc.

- Abstract
Viruses are being researched as cutting-edge therapeutic agents in cancer due to their selective oncolytic action against malignancies. Immuno-oncolytic viruses are a potential category of anticancer treatments because they have natural features that allow viruses to efficiently infect, replicate, and destroy cancer cells. Oncolytic viruses may be genetically modified; engineers can use them as a platform to develop additional therapy modalities that overcome the limitations of current treatment approaches. In recent years, researchers have made great strides in the understanding relationship between cancer and the immune system. An increasing corpus of research is functioning on the immunomodulatory functions of oncolytic virus (OVs). Several clinical studies are currently underway to determine the efficacy of these immuno-oncolytic viruses. These studies are exploring the design of these platforms to elicit the desired immune response and to supplement the available immunotherapeutic modalities to render immune-resistant malignancies amenable to treatment. This review will discuss current research and clinical developments on Vaxinia immuno-oncolytic virus., (© 2023.

- Abstract
Proteolysis-targeting chimeras (PROTACs) are being developed as an effective method for degrading cancer-related proteins by modifying the endogenous ubiquitin-proteasome system. To investigate the dynamics between an E3 ligase and target protein, researchers have developed a wide variety of bifunctional PROTACs by combining small molecule ligands. These PROTACs employ numerous ligands, some of which are reversible, some of which are irreversible, some attach to orthosteric sites, while others bind to allosteric sites. Some are agonists, while others are antagonists, and the target protein may be activated in either a positive or negative manner. A variety of targeted ligand approaches can be used to enhance PROTAC properties, including tumor selectivity and drug delivery, and to overcome drug resistance. The processes and behaviors of small molecule-based PROTACs and targeted proteolysis approaches as anticancer therapeutic molecules have been introduced in this mini-review., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2023 Elsevier B.V.

- Abstract
Nanomaterials have been the focus of intensive development and research in the medical and industrial sectors over the past several decades. Some studies have found that these compounds can have a detrimental impact on living organisms, including their cellular components. Despite the obvious advantages of using nanomaterials in a wide range of applications, there is sometimes skepticism caused by the lack of substantial proof that evaluates potential toxicities. The interactions of nanoparticles (NPs) with cells of the immune system and their biomolecule pathways are an area of interest for researchers. It is possible to modify NPs so that they are not recognized by the immune system or so that they suppress or stimulate the immune system in a targeted manner. In this review, we look at the literature on nanomaterials for immunostimulation and immunosuppression and their impact on how changing the physicochemical features of the particles could alter their interactions with immune cells for the better or for the worse (immunotoxicity). We also look into whether the NPs have a unique or unexpected (but desired) effect on the immune system, and whether the surface grafting of polymers or surface coatings makes stealth nanomaterials that the immune system cannot find and get rid of.

- Abstract
The vagina is an essential part of the female reproductive system and offers many potential benefits over conventional drug delivery, including a large surface area for drug absorption, relatively low enzymatic activity, avoiding first-pass effects, and ease of administration. The vaginal mucosal cavity is an effective route for administering therapeutic agents that are intended both for local and systemic administration. The present review provides a comprehensive overview of recent trends and developments in vaginal drug delivery. Marketed formulations and products under clinical study are also reviewed. Various novel vaginal delivery systems have been studied in recent years as effective tools for delivering a range of therapeutic agents to the vagina. These systems offer numerous benefits, including sustained delivery, improved bioavailability, effective permeation, and higher efficacy. The recent focus of the scientific community is on the development of safe and efficient drug delivery systems, such as nanoparticles, microparticles, vesicular systems, vaginal rings, microneedles, etc., for vaginal application. Various factors, such as the physicochemical properties of the drugs, the volume and composition of the vaginal fluid, the pH of the vaginal fluid, the thickness of the vaginal epithelium, and the influence of sexual intercourse may influence the release of drugs from the delivery system and subsequent absorption from the vaginal route. To date, only a limited number of in vivo studies on novel vaginal DDS have been reported. Additionally, drug release kinetics under varying vaginal environments is also not well understood. More research is needed to ensure the suitability, biocompatibility, and therapeutic effectiveness of novel DDS for vaginal delivery. Although numerous strategies and interventions have been developed, clinical translation of these systems remains a challenge. The toxicity of the carrier system is also an important consideration for future clinical applications., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Respiratory diseases (RDs), such as chronic obstructive pulmonary disease, cystic fibrosis, asthma, and pneumonia, are associated with significant morbidity and mortality. Treatment usually consists of antibiotics and steroids. Relevant published literature reviews, studies, and clinical trials were accessed from institutional and electronic databases. The keywords used were respiratory diseases, steroids, antibiotics, and combination of steroids and antibiotics. Selected articles and literature were carefully reviewed. Antibiotics are often prescribed as the standard therapy to manage RDs. Types of causative respiratory pathogens, spectrum of antibiotics activity, route of administration, and course of therapy determine the type of antibiotics that are prescribed. Despite being associated with good clinical outcome, treatment failure and recurrence rate are still high. In addition, antibiotic resistance has been widely reported due to bacterial mutations in response to the use of antibiotics, which render them ineffective. Nevertheless, there has been a growing demand for corticosteroids (CS) and antibiotics to treat a wide variety of diseases, including various airway diseases, due to their immunosuppressive and anti-inflammatory properties. The use of CS is well established and there are different formulations based on the diseases, such as topical administration, tablets, intravenous injections, and inhaled preparations. Both antibiotics and CS possess similar properties in terms of their anti-inflammatory effects, especially regulating cytokine release. Thus, the current review examines and discusses the different applications of antibiotics, CS, and their combination in managing various RDs. Drawbacks of these interventions are also discussed., (© 2022 Wiley Periodicals LLC.)

- Abstract
When DNA repair is inadequate it increases the chances of the genome becoming unstable and it undergoes a malignant mutation. The deficiency of DNA repair PARP proteins may be leveraged for cancer therapy by increasing genomic instability and causing massive DNA damage in cancer cells. DNA repair components are under increased demand in cancer cells because of the continuous replication of DNA. The oncogenic loss of BRCA and an inefficient DNA repair led to cancer cells being dependent on particular DNA repair pathways, like the Poly (ADP-ribose) polymerase pathway. Breast cancer gene 1 and 2 plays a crucial role in DNA repair and genome integrity explaining how BRCA1 and BRCA2 mutations raise the menace of cancer. PARP inhibitors inhibit the base exclusion repair pathway, resulting in the buildup of unrepaired single strand breaks, which cause inflated replication forks in the S phase and subsequently the development of damaging double stranded breaks. Cells having BRCA mutations are unable to repair DNA breaks, leading to apoptosis and eventually death of cancer cells. Numerous indicators, such as a lack of homologous recombination and a high degree of replication pressure, indicate that this therapy will be very effective. Combining PARP inhibitors with chemotherapy, an immune checkpoint inhibitor, and a targeted drug is an effective strategy for combating PARP inhibitors resistance. Several PARP-based combination approaches are in preclinical and clinical development. Various clinical trials are successfully completed and some are undergoing to evaluate the efficacy of these molecules. This review will describe the current views and clinical updates on PARP inhibitors., (© 2022.

- Abstract
The transport of drugs to the central nervous system is the most challenging task for conventional drug delivery systems. The reduced permeability of drugs through the blood-brain barrier is a major hurdle in delivering drugs to the brain. Hence, various strategies for improving drug delivery through the blood-brain barrier are being explored. Novel drug delivery systems (NDDS) offer several advantages, including high chemical and biological stability, suitability for both hydrophobic and hydrophilic drugs, and can be administered through different routes. Furthermore, the conjugation of suitable ligands with these carriers tends to potentiate targeting to the endothelium of the brain and could facilitate the internalization of drugs through endocytosis. Further, the intranasal route has also shown potential, as a promising alternate route, for the delivery of drugs to the brain. This can deliver the drugs directly to the brain through the olfactory pathway. In recent years, several advancements have been made to target and overcome the barriers of the brain. This article deals with a detailed overview of the diverse strategies and delivery systems to overcome the barriers of the brain for effective delivery of drugs., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
To achieve optimal immunogenicity, particulates present a promising vehicle for antigen delivery and have the potential to skew immune response. Particulate vaccine offers several advantages including targeting of antigen to sentinel cells, protection from degradation, sustained release, and itself acts an adjuvant mimics viral structure. Adjuvant presence is vital in overcoming the poor immunogenicity of vaccines, e.g., subunit vaccines. Adjuvants have antigen dose sparing potential and provide danger signals to alert the immune system. Various particulate carriers received attention in the delivery of vaccine antigens such as virus-like particles, liposomes, immunostimulating complexes, and polymeric particles. This review also discussed the properties of particles such as size, shape, and rigidity affecting the immunological outcome. It further highlights the cellular uptake of the particulate vaccine, antigen processing, and its presentation by antigen-presenting cells. For mass vaccination, especially in countries lacking resources, effect of storage temperature condition on stability of vaccine is pivotal. The current COVID-19 pandemic is not showing any signs of abatement and role of nanocarriers are highly relevant in SARS-CoV-2 pandemic as an effective immunization strategy. Eradication of pandemic demands the rapid evaluation of multiple approaches that can provides successful vaccination platform, enabling scalability and global distribution.

- Abstract
Ganoderma lucidium extract powder (GLEP) contains various polysaccharides which are well known for their antioxidant and anti-inflammatory actions. Probiotics (PB) are well-established for providing a plethora of health benefits. Hence, use of mushroom polysaccharides and probiotics as carriers to solidify liquisolid formulation is anticipated to function as functional excipients i.e. as adsorbent that may provide therapeutic benefits. Quercetin (QUR) has been used as model lipophilic drug in this study. QUR loaded liquisolid compacts (LSCs) were formulated using Tween 80 as solvent. These were further solidified using a combination of PB and GLEP as carriers. Aerosil-200 (A-200) was used as coating agent. The formulation exhibited very good flow characteristics. Dissolution rate of raw QUR was found to be less than 10% in 60 min while in case of QUR loaded LSCs, more than 90% drug release was observed within 5 min. Absence of crystalline peaks of QUR in the DSC and PXRD reports of LSCs and their porous appearance in SEM micrographs indicate that QUR was successfully incorporated in the LSCs. The developed formulation was found to be stable on storage under accelerated stability conditions., (Copyright © 2021 Elsevier B.V. All rights reserved.)

- Abstract
Immune-chromatographic kits are being used since several years in the rapid detection of infectious diseases. It is also called the lateral flow technique, and is used for antigen or antibody detection. There are a series of steps involved in the development of these immune-chromatographic test kits. Still, the preparation of gold nanoparticles (AuNPs) is an important quality variable for the immune-chromatographic test kit sensitivity. The immune chromatographic test must be specific in detection for specific antigen and antibody; this implies that the test kit should not show a false result. Secondly, the test kit should be sensitive enough to give a readable result, and the intensity of the test line should increase or decrease with the concentration of an analytic sample. Various factors can influence the performance of a test. Temperature differences in AuNPs preparation can alter the assay kinetics and contribute to assay variability. Other factors such as assay components, manufacturing processes and reagent variation also contribute to assay precision and accuracy. It is important to note that assay reproducibility is the combined effect of individual sources of variability. The authors have synthesized AuNPs by immediately controlling the reaction temperature. Different batches of Malaria rapid test kit were developed and the test kit sensitivity was analysed. It was found that test kits designed with temperature-controlled AuNPs sensor had reproducible uniformity in terms of batch to batch sensitivity than AuNPs synthesized by conventional Turkevich and Fern process., (© 2021 The Authors.

- Abstract
Majority of the representative drugs customarily interact with multiple targets manifesting unintended side effects. In addition, drug resistance and over expression of the cellular efflux-pumps render certain classes of drugs ineffective. With only a few innovative formulations in development, it is necessary to identify pharmacophores and novel strategies for creating new drugs. The conjugation of dissimilar pharmacophoric moieties to design hybrid molecules with an attractive therapeutic profile is an emerging paradigm in the contemporary drug development regime. The recent decade witnessed the remarkable biological potential of 1,3,5-triazine framework in the development of various chemotherapeutics. The appending of the 1,3,5-triazine nucleus to biologically relevant moieties has delivered exciting results. The present review focuses on 1,3,5-triazine based hybrid molecules in the development of pharmaceuticals., (© 2020 Wiley Periodicals, lnc.)
