    PMID: 32579723 DOI: 10.1002/ddr.21704
    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.

    The highly contagious coronavirus, which had already affected more than 2 million people in 210 countries, triggered a colossal economic crisis consequently resulting from measures adopted by various goverments to limit transmission. This has placed the lives of many people infected worldwide at great risk. Currently there are no established or validated treatments for COVID-19, that is approved worldwide. Nanocarriers may offer a wide range of applications that could be developed into risk-free approaches for successful therapeutic strategies that may lead to immunisation against the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) which is the primary causative organism that had led to the current COVID-19 pandemic. We address existing as well as emerging therapeutic and prophylactic approaches that may enable us to effectively combat this pandemic, and also may help to identify the key areas where nano-scientists can step in.

    Chan Y, Ng SW, Mehta M, Anand K, Kumar Singh S, Gupta G, et al.
    Med Hypotheses, 2020 Nov;144:110298.
    PMID: 33254489 DOI: 10.1016/j.mehy.2020.110298
    Outbreaks of influenza infections in the past have severely impacted global health and socioeconomic growth. Antivirals and vaccines are remarkable medical innovations that have been successful in reducing the rates of morbidity and mortality from this disease. However, the relentless emergence of drug resistance has led to a worrisome increase in the trend of influenza outbreaks, characterized by worsened clinical outcomes as well as increased economic burden. This has prompted the need for breakthrough innovations that can effectively manage influenza outbreaks. This article provides an insight into a novel hypothesis that describes how the integration of nanomedicine, with the development of drugs and vaccines can potentially enhance body immune response and the efficacies of anti-viral therapeutics to combat influenza infections.

    PMID: 33352062 DOI: 10.1098/rsob.200286
    Excessive exposure to toxic substances or chemicals in the environment and various pathogens, including viruses and bacteria, is associated with the onset of numerous brain abnormalities. Among them, pathogens, specifically viruses, elicit persistent inflammation that plays a major role in Alzheimer's disease (AD) as well as dementia. AD is the most common brain disorder that affects thought, speech, memory and ability to execute daily routines. It is also manifested by progressive synaptic impairment and neurodegeneration, which eventually leads to dementia following the accumulation of Aβ and hyperphosphorylated Tau. Numerous factors contribute to the pathogenesis of AD, including neuroinflammation associated with pathogens, and specifically viruses. The human immunodeficiency virus (HIV) is often linked with HIV-associated neurocognitive disorders (HAND) following permeation through the blood-brain barrier (BBB) and induction of persistent neuroinflammation. Further, HIV infections also exhibited the ability to modulate numerous AD-associated factors such as BBB regulators, members of stress-related pathways as well as the amyloid and Tau pathways that lead to the formation of amyloid plaques or neurofibrillary tangles accumulation. Studies regarding the role of HIV in HAND and AD are still in infancy, and potential link or mechanism between both is not yet established. Thus, in the present article, we attempt to discuss various molecular mechanisms that contribute to the basic understanding of the role of HIV-associated neuroinflammation in AD and HAND. Further, using numerous growth factors and drugs, we also present possible therapeutic strategies to curb the neuroinflammatory changes and its associated sequels.

    Ng PQ, Ling LSC, Chellian J, Madheswaran T, Panneerselvam J, Kunnath AP, et al.
    Curr Pharm Des, 2020;26(36):4580-4590.
    PMID: 32520681 DOI: 10.2174/1381612826666200610111013
    Many plant-based bioactive compounds have been serving as the origin of drugs since long ago and many of them have been proven to have medicinal value against various chronic diseases, including, cancer, arthritis, hepatic diseases, type-2 diabetes and cardiovascular diseases. However, their clinical applications have been limited due to their poor water solubility, stability, low bioavailability and extensive transformation due to the first-pass metabolism. The applications of nanocarriers have been proven to be able to improve the delivery of bioactive phytoconstituents, resulting in the enhancement of various pharmacokinetic properties and thereby increasing the therapeutic value of phytoconstituents. These biocompatible nanocarriers also exert low toxicity to healthy cells. This review focuses on the uses and applications of different types of nanocarriers to enhance the delivery of phytoconstituents for the treatment of various chronic diseases, along with comparisons related to bioavailability and therapeutic efficacy of nano phytoconstituents with native phytoconstituents.

    BACKGROUND: The newly emerged coronavirus SARS-CoV-2, first reported in December 2019, has infected about five and a half million people globally and resulted in nearly 9063264 deaths until the 24th of June 2020. Nevertheless, the highly contagious virus has instigated an unimaginably rapid response from scientific and medical communities.

    OBJECTIVES: Pioneering research on molecular mechanisms underlying the viral transmission, molecular pathogenicity, and potential treatments will be highlighted in this review. The development of antiviral drugs specific to SARS-CoV-2 is a complicated and tedious process. To accelerate scientific discoveries and advancement, researchers are consolidating available data from associated coronaviruses into a single pipeline, which can be readily made available to vaccine developers.

    METHODS: In order to find studies evaluating the COVID-19 virus epidemiology, repurposed drugs and potential vaccines, web searches and bibliographical bases have been used with keywords that matches the content of this review.

    RESULTS: The published results of SARS-CoV-2 structures and interactomics have been used to identify potential therapeutic candidates. We illustrate recent publications on SARS-CoV-2, concerning its molecular, epidemiological, and clinical characteristics, and focus on innovative diagnostics technologies in the production pipeline. This objective of this review is to enhance the comprehension of the unique characteristics of SARS-CoV-2 and strengthen future control measures.

    Lay Summary: An innovative analysis is evaluating the nature of the COVID-19 pandemic. The aim is to increase knowledge of possible viral detection methods, which highlights several new technology limitations and advantages. We have assessed some drugs currently for patients (Lopinavir, Ritonavir, Anakinra and Interferon beta 1a), as the feasibility of COVID-19 specific antivirals is not presently known. The study explores the race toward vaccine development and highlights some significant trials and candidates in various clinical phases. This research addresses critical knowledge gaps by identifying repurposed drugs currently under clinical trials. Findings will be fed back rapidly to the researchers interested in COVID 19 and support the evidence and potential of possible therapeutics and small molecules with their mode of action.

  11. Role of the Serine/Threonine Kinase 11 (STK11) or Liver Kinase B1 (LKB1) Gene in Peutz-Jeghers Syndrome
    Altamish M, Dahiya R, Singh AK, Mishra A, Aljabali AAA, Satija S, et al.
    Crit Rev Eukaryot Gene Expr, 2020;30(3):245-252.
    PMID: 32749111 DOI: 10.1615/CritRevEukaryotGeneExpr.2020033451
    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.

    The application of medicinal plants has captured the interest of researchers in recent times due to their potent therapeutic properties and a better safety profile. The prominent role of herbal products in treating and preventing multiple diseases dates back to ancient history and most of the modern drugs today originated from their significant sources owing to their ability to control multiple targets via different signalling pathways. Among them, flavonoids consist of a large group of polyphenols, which are well known for their various therapeutic benefits. Rutin is considered one of the attractive phytochemicals and important flavonoids in the pharmaceutical industry due to its diverse pharmacological activities via various underlying molecular mechanisms. It is usually prescribed for various disease conditions such as varicosities, haemorrhoids and internal haemorrhage. In this review, we have discussed and highlighted the different molecular mechanisms attributed to the various pharmacological activities of rutin, such as antioxidant, anti-inflammatory, anticancer, anti-allergic and antidiabetic. This review will be beneficial to herbal, biological and molecular scientists in understanding the pharmacological relevance of rutin at the molecular level.
  13. MicroRNAs as Biomarker for Breast Cancer
    Aggarwal T, Wadhwa R, Gupta R, Paudel KR, Collet T, Chellappan DK, et al.
    Endocr Metab Immune Disord Drug Targets, 2020;20(10):1597-1610.

    Regardless of advances in detection and treatment, breast cancer affects about 1.5 million women all over the world. Since the last decade, genome-wide association studies (GWAS) have been extensively conducted for breast cancer to define the role of miRNA as a tool for diagnosis, prognosis and therapeutics. MicroRNAs are small, non-coding RNAs that are associated with the regulation of key cellular processes such as cell multiplication, differentiation, and death. They cause a disturbance in the cell physiology by interfering directly with the translation and stability of a targeted gene transcript. MicroRNAs (miRNAs) constitute a large family of non-coding RNAs, which regulate target gene expression and protein levels that affect several human diseases and are suggested as the novel markers or therapeutic targets, including breast cancer. MicroRNA (miRNA) alterations are not only associated with metastasis, tumor genesis but also used as biomarkers for breast cancer diagnosis or prognosis. These are explained in detail in the following review. This review will also provide an impetus to study the role of microRNAs in breast cancer.

    Tobacco smoke is not only a leading cause for chronic obstructive pulmonary disease, cardiovascular disorders, and lung and oral cancers, but also causes neurological disorders such as Alzheimer 's disease. Tobacco smoke consists of more than 4500 toxic chemicals, which form free radicals and can cross blood-brain barrier resulting in oxidative stress, an extracellular amyloid plaque from the aggregation of amyloid β (Aβ) peptide deposition in the brain. Further, respiratory infections such as Chlamydia pneumoniae, respiratory syncytial virus have also been involved in the induction and development of the disease. The necessary information collated on this review has been gathered from various literature published from 1995 to 2019. The review article sheds light on the role of smoking and respiratory infections in causing oxidative stress and neuroinflammation, resulting in Alzheimer's disease (AD). This review will be of interest to scientists and researchers from biological and medical science disciplines, including microbiology, pharmaceutical sciences and the translational researchers, etc. The increasing understanding of the relationship between chronic lung disease and neurological disease is two-fold. First, this would help to identify the risk factors and possible therapeutic interventions to reduce the development and progression of both diseases. Second, this would help to reduce the probable risk of development of AD in the population prone to chronic lung diseases.

    Biofilms are a collective of multiple types of bacteria that develop on a variety of surfaces. Biofilm development results in heightened resistance to antibiotics. Quorum sensing plays an important role in biofilm development as it is one of the common communication mechanisms within cells, which balances and stabilizes the environment, when the amount of bacteria increases. Because of the important implications of the roles biofilms play in infectious diseases, it is crucial to investigate natural antibacterial agents that are able to regulate biofilm formation and development. Various studies have suggested that natural plant products have the potential to suppress bacterial growth and exhibit chemopreventive traits in the modulation of biofilm development. In this review, we discuss and collate potential antibiofilm drugs and biological molecules from natural sources, along with their underlying mechanisms of action. In addition, we also discuss the antibiofilm drugs that are currently under clinical trials and highlight their potential future uses.
  17. Anti-inflammatory and anticancer activities of Naringenin-loaded liquid crystalline nanoparticles in vitro
    Wadhwa R, Paudel KR, Chin LH, Hon CM, Madheswaran T, Gupta G, et al.
    J Food Biochem, 2021 01;45(1):e13572.
    PMID: 33249629 DOI: 10.1111/jfbc.13572
    In this study, we had developed Naringenin-loaded liquid crystalline nanoparticles (LCNs) and investigated the anti-inflammatory and anticancer activities of Naringenin-LCNs against human airway epithelium-derived basal cells (BCi-NS1.1) and human lung epithelial carcinoma (A549) cell lines, respectively. The anti-inflammatory potential of Naringenin-LCNs evaluated by qPCR revealed a decreased expression of IL-6, IL-8, IL-1β, and TNF-α in lipopolysaccharide-induced BCi-NS1.1 cells. The activity of LCNs was comparable to the positive control drug Fluticasone propionate (10 nM). The anticancer activity was studied by evaluating the antiproliferative (MTT and trypan blue assays), antimigratory (scratch wound healing assay, modified Boyden chamber assay, and immunoblot), and anticolony formation activity in A549 cells. Naringenin LCNs showed promising antiproliferative, antimigratory, and anticolony formation activities in A549 cells, in vitro. Therefore, based on our observations and results, we conclude that Naringenin-LCNs may be employed as a potential therapy-based intervention to ameliorate airway inflammation and to inhibit the progression of lung cancer. PRACTICAL APPLICATIONS: Naringenin was encapsulated into liquid crystalline nanoparticles, thus, attributing to their sustained-release nature. In addition, Naringenin-loaded LCNs efficiently reduced the levels of pro-inflammatory markers, namely, IL-1β, IL-6, TNF-α, and IL-8. In addition, the Naringenin-loaded LCNs also possess potent anticancer activity, when tested in the A549 cell line, as revealed by the inhibition of proliferation and migration of cells. They also attenuated colony formation and induced apoptosis in the A549 cells. The findings from our study could form the basis for future research that may be translated into an in vivo model to validate the possible therapeutic alternative for lung cancer using Naringenin-loaded LCNs. In addition, the applications of Naringenin-loaded LCNs as an intervention would be of great interest to biological, formulation and respiratory scientists and clinicians.
  18. Fulltext Induction of Caspase-Mediated Apoptosis in HepG2 Liver Carcinoma Cells Using Mutagen-Antioxidant Conjugated Self-Assembled Novel Carbazole Nanoparticles and In Silico Modeling Studies
    Anand K, Abdul NS, Ghazi T, Ramesh M, Gupta G, Tambuwala MM, et al.
    ACS Omega, 2021 Jan 12;6(1):265-277.
    PMID: 33458478 DOI: 10.1021/acsomega.0c04461
    In this study, novel self-assembled carbazole-thiooctanoic acid nanoparticles (CTNs) were synthesized from amino carbazole (a mutagen) and thiooctanoic acid (an antioxidant). The nanoparticles were characterized using hyperspectral techniques. Then, the antiproliferative potential of CTNs was determined in HepG2 liver carcinoma cells. This study employed a solvent-antisolvent interaction method to synthesize a spherical CTN of size less than 50 nm. Moreover, CT was subsequently capped to gold nanoparticles (AuNPs) in the additional comparative studies. The CT derivative was synthesized from carbazole and lipoic acid by the amide bond formation reaction using a coupling agent. Furthermore, it was characterized using infrared (IR), 1H nuclear magnetic resonance, dynamic light scattering (DLS), and transmission electron microscopy techniques. The CT-capped gold nanoparticles (CTAuNPs) were prepared from CT, chloroauric acid, and NaBH4. The CTAuNPs were characterized using ultraviolet-visible, high-resolution TEM, DLS, and Fourier transform IR techniques. The cytotoxicity and apoptosis-inducing ability of both nanoparticles were determined in HepG2 cells. The results demonstrate that CTNs exhibit antiproliferative activity in the cancerous HepG2 cells. Moreover, molecular docking and molecular dynamics studies were conducted to explore the therapeutic potential of CT against human EGFR suppressor protein to gain more insights into the binding mode of the CT, which may show a significant role in anticancer therapy.

    ETHNOPHARMACOLOGICAL RELEVANCE: Blepharis is an Afro-Asiatic genus belonging to the family Acanthaceae. It comprises about 126 species that occur in arid and semi-arid habitats. Some species of Blepharis are used in traditional medicines in different countries mainly for their anti-inflammatory, wound healing activities along with treatment of gastrointestinal disorders and bone fractures.

    AIM OF THE REVIEW: The present review aims to collate and analyze the available data and information on distribution, traditional uses, chemical constituents and pharmacological activities of Blepharis.

    METHODS: Scientific information of genus Blepharis was retrieved from the online bibliographic databases such as MEDLINE/PubMed, SciFinder, Web of Science and Google Scholar and secondary resources including books and proceedings.

    RESULTS: Seven species of Blepharis were found to be reported frequently as useful in folklore in African and Asian countries. B. maderaspatensis was found to be widely used in Indian traditional medicines whereas the B. ciliaris and B. edulis were common in folklore of Egypt, Jordan, and Arabia. Active phytochemicals of Blepharis are flavonoids from B. ciliaris, alkaloids from B. sindica, phenolic acid derivatives, and phytosterols, and derivatives of hydroxamic acids from B. edulis resulted in possessing diverse biological properties such as anti-microbial, anti-inflammatory, and anti-cancer.

    CONCLUSIONS: Various species of Blepharis were found to be used in traditional medicine systems in African and Asian countries. Few of these species were studied for their bioactive chemical constituents however the activity guided isolation studies are not performed. Similarly, detailed pharmacological studies in animal models to explore their mechanism of action are also not reported. Future studies should focus on these aspects related to the medicinally used species of Blepharis. The detailed and comprehensive comparative analysis presented here gives valuable information of the currently used Blepharis species and pave the way to investigate other useful species of Blepharis pertaining to ethnobotany, phytochemistry and discovery of new drugs.

  20. Targeting eosinophils in respiratory diseases: Biological axis, emerging therapeutics and treatment modalities
    Lee LY, Hew GSY, Mehta M, Shukla SD, Satija S, Khurana N, et al.
    Life Sci, 2021 Feb 15;267:118973.
    PMID: 33400932 DOI: 10.1016/j.lfs.2020.118973
    Eosinophils are bi-lobed, multi-functional innate immune cells with diverse cell surface receptors that regulate local immune and inflammatory responses. Several inflammatory and infectious diseases are triggered with their build up in the blood and tissues. The mobilization of eosinophils into the lungs is regulated by a cascade of processes guided by Th2 cytokine generating T-cells. Recruitment of eosinophils essentially leads to a characteristic immune response followed by airway hyperresponsiveness and remodeling, which are hallmarks of chronic respiratory diseases. By analysing the dynamic interactions of eosinophils with their extracellular environment, which also involve signaling molecules and tissues, various therapies have been invented and developed to target respiratory diseases. Having entered clinical testing, several eosinophil targeting therapeutic agents have shown much promise and have further bridged the gap between theory and practice. Moreover, researchers now have a clearer understanding of the roles and mechanisms of eosinophils. These factors have successfully assisted molecular biologists to block specific pathways in the growth, migration and activation of eosinophils. The primary purpose of this review is to provide an overview of the eosinophil biology with a special emphasis on potential pharmacotherapeutic targets. The review also summarizes promising eosinophil-targeting agents, along with their mechanisms and rationale for use, including those in developmental pipeline, in clinical trials, or approved for other respiratory disorders.
