Analytics, Properties and Applications of Biologically Active Stilbene Derivatives.

Stilbene and its derivatives belong to the group of biologically active compounds. Some derivatives occur naturally in various plant species, while others are obtained by synthesis. Resveratrol is one of the best-known stilbene derivatives. Many stilbene derivatives exhibit antimicrobial, antifungal or anticancer properties. A thorough understanding of the properties of this group of biologically active compounds, and the development of their analytics from various matrices, will allow for a wider range of applications. This information is particularly important in the era of increasing incidence of various diseases hitherto unknown, including COVID-19, which is still present in our population. The purpose of this study was to summarize information on the qualitative and quantitative analysis of stilbene derivatives, their biological activity, potential applications as preservatives, antiseptics and disinfectants, and stability analysis in various matrices. Optimal conditions for the analysis of the stilbene derivatives in question were developed using the isotachophoresis technique.

Drug–Target Interaction Deep Learning-Based Model Identifies the Flavonoid Troxerutin as a Candidate TRPV1 Antagonist

Based on the advances made by artificial intelligence (AI) technologies in drug discovery, including target identification, hit molecule identification, and lead optimization, this study investigated natural compounds that could act as transient receptor potential vanilloid 1 (TRPV1) channel protein antagonists. Using a molecular transformer drug–target interaction (MT-DTI) model, troxerutin was predicted to be a TRPV1 antagonist at IC50 582.73 nM. In a TRPV1-overexpressing HEK293T cell line, we found that troxerutin antagonized the calcium influx induced by the TRPV1 agonist capsaicin in vitro. A structural modeling and docking experiment of troxerutin and human TRPV1 confirmed that troxerutin could be a TRPV1 antagonist. A small-scale clinical trial consisting of 29 participants was performed to examine the efficacy of troxerutin in humans. Compared to a vehicle lotion, both 1% and 10% w/v troxerutin lotions reduced skin irritation, as measured by skin redness induced by capsaicin, suggesting that troxerutin could ameliorate skin sensitivity in clinical practice. We concluded that troxerutin is a potential TRPV1 antagonist based on the deep learning MT-DTI model prediction. The present study provides a useful reference for target-based drug discovery using AI technology and may provide useful information for the integrated research field of AI technology and biology.

Ultra High-Throughput Screening Assays for Inhibitors of TMPRSS2 and SPIKE Interaction

SARS-CoV-2, the coronavirus that causes the disease COVID- 19, was identified over three years ago, yet current small molecule therapies have limited usefulness and resistance to therapies and vaccines is inevitable. Ultra high-throughput screening (uHTS) assays for novel and repurposed inhibitors of a protein-protein interaction in the viral life cycle could be used to screen a vast number of compounds with a specific target of action. In particular, the interaction between viral SPIKE protein and human TMPRSS2 is an understudied, yet critical step in viral entry. Thus, we aim to create uHTS assays to rapidly and affordably identify inhibitors of the TMPRSS2 and SPIKE interaction for further biochemical studies and therapeutic development for SARS-CoV-2.We first sought to create a Time Resolved-Forster/Fluorescence Energy Transfer (TR-FRET) assay which uses lysates of cells with overexpressed SPIKE and TMPRSS2 and fluorescently labeled antibodies to detect interactions between these proteins. Initially, we developed and optimized this TR-FRET assay in a 384-well plate then miniaturized to a 1536-well plate. We conducted a pilot screen of compounds with known biological activity to test this assay's screening capabilities. To further narrow the hits from this TR-FRET screen, we developed an orthogonal uHTS Nanoluciferase Binary Technology (NanoBiT) assay to detect the interaction between tagged SPIKE and TMPRSS2 in live cells.With these two assays in hand, we expanded our TR-FRET screen to over 100 000 compounds and identified several that were also positive in the orthogonal NanoBiT assay. Four of these compounds were found to potentially interact with either SPIKE or TMPRSS2 from thermal shift experiments, providing support for their action as SPIKE and TMPRSS2 interaction inhibitors. Thus, we have developed TR-FRET and NanoBiT orthogonal uHTS assays which have allowed for the discovery of several possible repurposed and novel inhibitors of the SPIKE/ TMPRSS2 interaction. These uHTS assays can be employed as a model for future drug discovery efforts and the compounds identified may be used as exciting starting points for development of inhibitors of SARS-CoV-2.

Modification of the Aeration-Supplied Configuration in the Biodrying Process for Refuse-Derived Fuel (RDF) Production

Biodrying is an essential part of the mechanical–biological treatment process that minimizes moisture content and simultaneously maximizes heating value for refuse-derived fuel (RDF) production. Although the mechanical separation process operates effectively in Thailand's RDF production, high organic content levels and their degradation cause moisture contamination in RDF, producing wet RDF. Aeration is essential for an effective biodrying process, and can reduce RDF's moisture content as well as increase its heating value. To maximize the biodrying effect, aeration should be optimized based on the waste conditions. This study proposes a modified aeration-supplied configuration for wet RDF biodrying. The aeration rate was modified based on the period within the biodrying operation;the first period is from the beginning until day 2.5, and the second period is from day 2.5 to day 5. The optimal aeration supply configuration was 0.5 m3/kg/day in the first period and then 0.3 m3/kg/day until the end of the process;this configuration yielded the greatest moisture content decrease of 35% and increased the low heating value of the biodried product by 11%. The final moisture content and low heating value were 24.07% and 4787 kcal/kg, respectively. Therefore, this optimal aeration-supplied configuration could be applied to meet the moisture content and low heating value requirements of the RDF production standard for Thailand's local cement industry.

A Review on Therapeutic Potential of Indian Herbal Plants to Counter Viral Infection and Disease Pathogenesis

Herbal plant extracts or purified phytocomponents have been extensively used to treat several diseases since ancient times. The Indian Ayurvedic system and Chinese traditional medicines have documented the medicinal properties of important herbs. In Ayurveda, the polyherbal formulation is known to exhibit better therapeutic efficacy compared to a single herb. This review focuses on six key ayurvedic herbal plants namely, Tinospora cordifolia, Withania somnifera, Glycyrrhiza glabra/Licorice, Zingiber officinale, Emblica officinalis and Ocimum sanctum. These plants possess specific phytocomponents that aid them in fighting infections and keeping body healthy and stress-free. Plants were selected due to their reported antimicrobial and anti-inflammatory effects in several diseases and effectiveness in controlling viral pathogenesis. An ad-vanced literature search was carried out using Pubmed and google scholar. Result(s): These medicinal plants are known to exhibit several protective features against various diseases or infections. Here we have particularly emphasized on antioxidant, anti-inflammatory, anti-microbial and immunomodulatory properties which are common in these six plants. Recent literature analysis has revealed Ashwagandha to be protective for Covid-19 too. The formulation from such herbs can exhibit synergism and hence better effectiveness against infection and related dis-eases. The importance of these medicinal herbs becomes highly prominent as it maintains the har-monious balance by way of boosting the immunity in a human body. Further, greater mechanistic analyses are required to prove their efficacy in fighting infectious diseases like Covid-19. It opens the arena for in-depth research of identifying and isolating the active components from these herbs and evaluating their potency to inhibit viral infections as polyherbal formulations.Copyright © 2023 Bentham Science Publishers.

Potentials for health and therapeutic benefits of garlic essential oils: Recent findings and future prospects

Garlic (Allium sativum) has been known for its potent medicinal activities and its interesting culinary role since ancient times. With over 200 phytochemicals and flavoring compounds elucidated and many others yet to, garlic promises to improve human health and vitality. Just like other phytochemical classes, essential oils for garlic have been reported to show interesting medical activities delving across diverse antimicrobial, cardio-protective, anti-cancer, anti-Alzheimer, anti-diabetic, and immunomodulatory activities. Garlic essential oils contain mainly volatile and non-volatile allyl-sulphur-based compounds, which are a product of the stream decomposition of Allicin (a major component of garlic extract). Although a lot of work has been done on Allicin, there is little substantive work on the bio-availability and toxicities of its essential oil. This study, however, reviewed the methods that in recent times have been used to extract essential oils from garlic, recent studies on composition and therapeutic activities of Garlic essential oils, and a predictive overview of their bioavailability and toxicity. Finally, recommendations for future studies and other interesting prospects of garlic were also highlighted.Copyright © 2022

Advancing global health with occupational epidemiology

This presentation will explore the essential role of occupational epidemiology in global health. Our field provides critical perspectives – relevant not only for the identification of health hazards at work but in global health more broadly – on the identification of risk factors for disease in populations, the weighing of evidence for causality, and the design and implementation of public health interventions. This presentation is informed by analyses of recent health crises including the COVID-19 pandemic, the epidemic of ‘deaths of despair' in the U.S. and the increasing toll of heat illnesses on a warming planet.In addition to study design and data analytic methods, occupational epidemiologists are trained to understand the physical and social environments in which work is conducted as well as the biological processes that link exposure to disease, and how all this impact population health. This multi-disciplinary training enables occupational epidemiologists to identify hazards and interventions that may be overlooked by other disciplines. Occupational epidemiologists learn that economic and political forces have powerful effects on the work environment, and this shapes their perspective on how evidence is weighed in public health decision-making. Rather than using rigid evidence to decision frameworks inspired by randomized controlled trials, evaluating evidence for action uses triangulation among diverse types and qualities of evidence to guide prevention. In occupational epidemiology, the precautionary principle can be understood as one aspect of the fundamental perspective that there is no pre-defined level of certainty that is needed before taking preventive action;instead, there are different amounts and qualities of evidence that are sufficient for each specific proposed intervention.A continuing supply of occupational epidemiologists is needed to respond to future global health challenges. Professional training programs are needed to ensure this workforce;training which includes epidemiology and biostatistics, physiology, occupational hygiene, engineering and the social and economic aspects of work and health. Occupational epidemiology should be core training in global health programs.

AIDrugApp: artificial intelligence-based Web-App for virtual screening of inhibitors against SARS-COV-2

Currently, there is no effective cure for SARS-COVID-19 diseases. The identification of novel therapeutic targets and drug-like compounds is required for the development of anti-COVID-19 drugs. Virtual screening is currently the most significant component for identifying drug-like molecules from large datasets for drug design and development. However, there are no effective easily available and user-friendly applications for virtual screening of drug leads against SARS-COV-2. Therefore, we have developed a user-friendly web-app named ‘AIDrugApp' for the virtual screening of inhibitor molecules against SARS-CoV-2. AIDrugApp is a novel open-access, deep learning AI-based inhibitory activity prediction and data statistics visualisation platform. Users can predict the inhibitory activities (Active/Inactive) and pIC-50 values of new compounds against SARS-CoV-2 replicase polyprotein, 3CLpro and human angiotensin-converting enzymes. It is also useful for virtual screening of chemical features of molecules towards SARS-COVID-19 clinical trial bioactivities. This paper presents the development and architecture of AIDrugApp. We also present two case studies where large sets of molecules were screened using the ‘Bioactivity Prediction' module of our app. Screened molecules were analysed further for validation by molecular docking and ADME analysis to identify the potential drug candidates.

Quantitative structure analysis of some molecules in drugs used in the treatment of COVID-19 with topological indices

COVID-19 is a disease caused by the new coronavirus, which has been spreading rapidly all over the world. There is no exact drug yet for the treatment of COVID-19 disease, and its treatment is tried to be provided with existing drugs. However, new drug research is being carried out to treat this disease. Topological indices are numerical descriptors based on the molecular graph of the molecular structure. Topological indices are used in modeling to predict the physicochemical properties and biological activities of molecules in the quantitative structure-property relationship (QSPR), quantitative structure-activity relationship (QSAR) studies. In this study, remdesivir, chloroquine, hydroxychloroquine, theaflavin, thalidomide, arbidol, lopinavir, ritonavir drugs used in the treatment of COVID-19 patients are studied. The QSPR model is designed using some degree-based indices, Mostar-type indices, and distance-based topological indices to predict the various physicochemical properties of these drugs. The relationship analyses between the physicochemical properties and the topological indices in the QSPR model are done by using the curvilinear regression method.

Method(s): A review of the literature was performed by screening different scientific databases to procure various immunomodulatory therapies for the treatment of SAR COV-2. Result(s): A comprehensive literature review indicated that different foods rich in vitamins (A-D), selenium and iron can enhance immunological response against various deleterious infections, whereas different nutritious drinks that include hydrogen-enriched water and green tea alleviate inflammation and elicit wound healing properties. Black cumin seeds and Garlic have a myriad of biological activities due to abundant bioactive phytochemicals that play an important role in the elimination of various bacterial and viral infections. Conclusion(s): These foods/supplements are relatively safe to consume and possess high toxicity profile and could be a potential nutritional intervention in order to create adequate immunity within a population to fight against this prevailing infection.Copyright © 2021 Bentham Science Publishers.

Molecular Docking Studies of Ocimum Americanum Secondary Metabolites Against SARS-Cov-2 Spike Protein

Introduction and Aim: The outbreak of Covid-19 pandemic since December 2019 has raised serious global health concern. Because of rapid human to human transmission and non-availability of clinically proven drugs or vaccines, this Covid-19 pandemic has created a great threat to mankind. Many naturally derived molecules are being investigated for the treatment of Covid-19. Ocimum americanum is one such significant medicinal plant possessing a variety of biological activities. Material(s) and Method(s): In the present study, seven phytochemicals were selected from O. americanum and were docked against SARS-CoV-2 spike protein which is an important site for virus to enter the host cell. Docking was performed using Autodock Vina and the ADME properties of all these seven ligands were predicted using the Swiss-ADME tool. The bioactivity score was also predicted using the Molinspiration tool. Besides the secondary metabolites, all these analyses were also performed for well-known antiviral drugs namely lopinavir and ritonavir. Result(s): The binding energy obtained from the docking studies of SARS-CoV-2 spike protein with Lopinavir, Ritonavir, Alpha-farnesene, Beta-farnesene, Eugenol, Linalool, Estragole, Limonene and 1,8-Cineole was found to be-5.2,-5.1,-4.7,-4.5,-4.3,-4.1,-4,-3.9 and-3.8 Kcal/Mol respectively. Swiss-ADME results also suggest that all the selected ligands follow the drug likeness properties and hence they could be taken for further drug discovery process. Conclusion(s): From the present in silico study, it can be concluded that secondary metabolites of O. americanum have potential inhibiting activity against spike protein of SARS-CoV-2. Isolation and efficacy studies in vitro may provide an insight into the drug discovery to fight Covid-19.Copyright © 2023, Indian Association of Biomedical Scientists. All rights reserved.

The Role of Aquatic Plants in Natural Products and Drug Discovery

Background: Phytochemicals and their derivatives/analogues represent over 50% of the current medicines worldwide in clinical use. Despite a significant contribution to the total bioactive natural plant products, aquatic plants are underestimated, and several species are extinct and in the endangered list. Objective(s): The aim of this review article is to draw the attention of common people and scientists toward a few important contributions of the aquatic plants to natural product chemistry and drug discovery by highlighting the chemical and pharmaceutical aspects of the same. Method(s): The presented data were collected and selected from the literature obtained by an online search for the ethnomedicinal properties, biological activities and bioactive chemical constituents of aquatic plants using Google Scholar, PubMed and Scifinder chemical abstract service. Result(s): The selected literature data revealed that the extract and compounds isolated from several aquatic plants possess significant biological/pharmaceutical properties. For example, the alpha-asarone (24) and asiatic acid (33) isolated from Acorus calamus and Centella asiatica, respectively, exhibited significant neuroprotective effects in vitro and in vivo. The cripowellin A (59), cripowellin C (60), cripowellin B (61) and cripowellin D (62), isolated from Crinum erubescens, exhibited potent antiplasmodial and antiproliferative activities with half maximal inhibitory concentration (IC50) in nanomolar range (11-260 nM). Several other alkaloids from different Crinum species have also shown anticancer properties against different cancer cell lines with IC50 value <5 microM. Alkaloids and resin glycosides, isolated from different Ipomoea species, have displayed significant psychotropic, psychotomimetic, anticancer, and antibacterial activities with IC50 value <5 microM. Conclusion(s): The aquatic plants play a significant role in the discovery of bioactive natural products. Although several biological activities and bioactive compounds have been reported from these plants, further assessment and scientific validation of most of their traditional usages still need to be done. There are several other similar species that are underestimated and not much explored. Many aquatic plants, such as Ipomoea carnea Jacq., Juncus lomatophyllus Spreng., Commelina benghalensis Linn, Gunnera perpensa L., Scirpus maritimus L. and Mentha longifolia (L.) L., may be considered for further evaluation. In addition to these, one should not undermine the potential of Crinum macowanii for COVID-19 pathogenesis, as its chemical constituent lycorine has shown significant SARS-CoV-2 inhibitory potential (EC50, 0.3 muM;SI >129). Furthermore, most rural communities are still using the wetland resources for their cultural, medicinal, economic, domestic, and agricultural needs. Hence, the conservation of aquatic plants and wetlands is an issue of great concern.Copyright © 2023 Bentham Science Publishers.

Pyrrole-Imidazole Polyamides - A Frontrunner in Nucleic Acid-Based Small Molecule Drugs

The remarkable success of messenger RNA vaccines against the ongoing coronavirus-2019 (COVID-19) pandemic renews attention toward nucleic acid therapeutics. While nucleic acid therapy using unmodified DNA or RNA is the primary focus in disease treatment, there is growing need to develop nucleic acid-based small molecules owing to their potential clinical benefits as drugs in terms of cost and scalability. While small molecules targeting protein-protein interactions are known to alter the transcriptional status of a cell, they can result in a transient effect and variation of bio-efficacy among patients. Small molecules targeting DNA and/or RNA are in demand in the precision medicine approach as they have consistent bioactivity among patients. This review details the progress of sequence-specific DNA-binding pyrrole-imidazole polyamides (PIPs) in modulating the transcriptional status of target gene(s) without altering the underlying DNA sequence. Here, the different versions of PIPs are listed, and also, how conjugating them with DNA alkylating agents, epigenetic modulators, and other drugs can improve their clinical utility as targeted transcription therapeutics. Owing to their specificity, functional diversity, and limited toxicity, PIP technology holds enormous promise as frontrunner in small-molecule-based nucleic acid drugs to precisely regulate therapeutically important genes on demand and treat intractable diseases.Copyright © 2023 Wiley-VCH GmbH.

A brief review on the medicinal uses of Cordyceps militaris

Introduction: Cordyceps, a popular Chinese medication, is made by drying caterpillar-borne Cordyceps fungus. The parasite needs an insect host or larvae host to survive. To strengthen those who were lacking in vitality, it was administered in tonic form. The biological effects of Cordyceps species are well documented. Its medicinal properties are because of the chemical constituents present in the mushroom namely cordycepin, cordymin, polysaccharides, glycoprotein, ergosterol, and other extracts. Material(s) and Method(s): Some of the biological activities of C.militaris are anti-cancer, anti-oxidant, anti-inflammatory, anti-aging, immunomodulatory, antimicrobials, immunosuppressive, hypolipidemic, hypoglycemic, neuroprotective, and fertility enhancer. Because of their bioactive compounds, edible fungus like C. militaris is a multifunctional food supplement. Many mushroom species can be grown on domestic refuse, popularizing the mushroom industry in sustainable economies worldwide. Conclusion(s): C. militaris extract can improve health when added to the diet. Further, the complexity of clinical investigations and the challenges of developing therapies using mushroom extracts are both exacerbated by the abundance of bioactive chemicals present in mushrooms. Cordycepin has the most therapeutic potential of all the bioactive compounds described in the studies. Recent studies indicate that cordycepin may be effective against COVID-19's SARS-CoV-2 strain. Therefore, this review lays the groundwork for clinical use and examines the research program for the near future.Copyright © 2023 The Author(s)
