<p class="Abstract">The present study aimed at the evaluation of anti-hyperglycemic and hepatoprotective potential of a new drug candidate, 5-[(4-chlorophenoxy) methyl]-1,3,4-oxadiazole-2-thiol (OXCPM) through in vitro and in vivo assays, respectively. The compound displayed excellent dose-dependent ɑ-amylase (28.0-92.0%), ɑ-glucosidase (40.3-93.1%) and hemoglobin glycosylation (9.0%-54.9%) inhibitory effects and promoted the uptake of glucose by the yeast cells (0.2 to 26.3%). The treatment of the isoniazid- and rifampicin- (p.o., 50 mg/kg of each) intoxicated rats with OXCPM (100 mg/kg, p.o.) resulted in restoring the normal serum levels of the non-enzymatic (total bilirubin, total protein and albumin) and bringing about a remarkable decrease in the levels of enzymatic (alanine transaminases, aspartate transaminases and alkaline phosphatase) biomarkers. The molecular docking studies indicated high binding affinity of the compound for hyperglycemia-related protein targets; fructose-1,6-bisphosphatase, beta<sub>2</sub>-adrenergic receptors and glucokinase. The results indicate that OXCPM may not only reduce hyperglycemia by enzyme inhibition but also the disease complications through protection of hemoglobin glycosylation and hepatic injury.</p><p class="Abstract"><strong>Video Clip of Methodology:</strong></p><p class="Abstract">Glucose uptake by yeast cells:   4 min 51 sec   <a href="https://www.youtube.com/v/8cJkuMtV0Wc">Full Screen</a>   <a href="https://www.youtube.com/watch?v=8cJkuMtV0Wc">Alternate</a></p>

<p class="Abstract">Two new pharmacologically active series of tetrazolopyridine-acetohydrazide conjugates [9 (a-n), 10 (a-n)] were synthesized by reacting a variety of suitably substituted benzaldehydes and isomeric 2-(5-(pyridin-3/4-yl)-2H-tetrazol-2-yl)acetohydrazides (7, 8). The synthesized compounds were analyzed through FTIR, <sup>1</sup>H NMR, <sup>13</sup>C NMR and elemental techniques. These acetohydrazides were screened for their in vivo antidiabetic activity and molecular docking studies. An excellent agreement was obtained as the best docked poses show-ed important binding features mostly based on interactions due to an oxygen atom and aromatic moieties of the series. The compounds 9a, 9c and 10l were found to be the most active in lowering blood glucose, having the potential of being good antidiabetic agents.</p><p><strong>Video Clip of Methodology</strong>:</p><p>Synthesis of 3/4-(2H-tetrazole-5-yl)pyridine: 1 min 57 sec   <a href="https://www.youtube.com/v/CHp8HxlEa2M">Full Screen</a>   <a href="https://www.youtube.com/watch?v=CHp8HxlEa2M">Alternate</a></p>

Introduction: Feruloyl Sucrose Esters (FSEs) are a class of Phenylpropanoid Sucrose Esters (PSEs) widely distributed in plants. They were investigated as potential selective Alpha Glucosidase Inhibitors (AGIs) to eliminate the side effects associated with the current commercial AGIs. The latter effectively lowers blood glucose levels in diabetic patients but causes severe gastrointestinal side effects. Methods: Systematic structure-activity relationship (SAR) studies using in silico, in vitro and in vivo experiments were used to accomplish this aim. FSEs were evaluated for their in vitro inhibition of starch and oligosaccharide digesting enzymes α-glucosidase and α-amylase followed by in silico docking studies to identify the binding modes. A lead candidate, FSE 12 was investigated in an STZ mouse model. Results: All active FSEs showed desired higher % inhibition of α-glucosidase and desired lower inhibition of α-amylase in comparison to AGI gold standard acarbose. This suggests a greater selectivity of the FSEs towards α-glucosidase than α-amylase, which is proposed to eliminate the gastrointestinal side effects. From the in vitro studies, the position and number of the feruloyl substituents on the sucrose core, the aromatic ‘OH’ group, and the diisopropylidene bridges were key determinants of the % inhibition of α-glucosidase and α-amylase. In particular, the diisopropylidene bridges are critical for achieving inhibition selectivity. Molecular docking studies of the FSEs corroborates the in vitro results. The molecular docking studies further reveal that the presence of free aromatic ‘OH’ groups and the substitution at position 3 on the sucrose core are critical for the inhibition of both the enzymes. From the in vitro and molecular docking studies, FSE 12 was selected as a lead candidate for validation in vivo. The oral co-administration of FSE 12 with starch abrogated the increase in post-prandial glucose and significantly reduced blood glucose excursion in STZ-treated mice compared to control (starch only) mice. Conclusion: Our studies reveal the potential of FSEs as selective AGIs for the treatment of diabetes, with a hypothetical reduction of side effects associated with commercial AGIs.

Corona Virus Infectious Disease-2019 (COVID-19) outbreak originated recently at Wuhan, China in December 2019. It has already spread rapidly to more than 200 countries and has been declared a pandemic by WHO. It is caused by a beta-coronavirus named as SARS-CoV-2. There is no definitive cure, either drug or vaccine, to treat or prevent this viral disease. Recently, the crystal structure of the main protease Mpro has been determined. Mpro is responsible for the proteolytic maturation of the polyprotein essential for the viral replication and transcription, which makes it an important drug target. The discovery of new drug molecules may take years before getting to the clinics. So, considering urgency we performed molecular docking studies using FDA approved drugs to identify molecules that could potentially bind to the substrate-binding site and inhibit SARS-CoV-2 main protease (Mpro). We used the Glide module in Schrodinger software suite to perform molecular docking studies followed by MM-GBSA based energy calculations to score the hit molecules. Molecular docking and manual analysis suggest that several drugs may bind and potentially inhibit Mpro. We also performed molecular simulations studies for selected compounds to evaluate protein-drug interactions. Interestingly, we observed only one antiviral compound, Adefovir, in the top50 list of compounds. Considering bioavailability, lesser toxicity, route of administration some of the top-ranked drugs including lumefantrine (antimalarial), dipyridamole (coronary vasodilator), dihydroergotamine (used for treating migraine), hexoprenaline (anti- asthmatic), riboflavin (vitamin B2) and pantethine (vitamin B5) may be taken forward for further in vitro and in vivo experiments to investigate their therapeutic potential.

Toxicity Estimation

The Indian Traditional Medicines System has long used Siddha polyherbal formulations for different viral diseases. The ingredients of these formulas have been proven to be antiviral. The study focuses on in silico computational evaluation of phytoconstituents of the official Siddha formulation Kabasura, Thonthasura, and Vishasura Kudineer, which were widely used in treating viral fever and respiratory infections and may influence the current SARS-CoV-2 coronary virus pandemic. Maestro interface (Schrödinger Suite, LLC, NY) was used for molecular docking studies against MPro (PDB ID 5R82, 6Y2F, and 6LU7), Nsp15 endoribonuclease (6W01), RNA-dependent RNA polymerase (6M71), and spike protein (6VW1) of SARS-CoV-2. In addition, pharmacokinetics (ADME) and safety profile prediction studies were performed to identify the best drug candidates using Qikpro and Toxicity Estimation Software Tool (T.E.S.T). A total of 36 compounds were screened, of which nine displayed strong binding affinity and drug-likeness. Luteolin and chrysoeriol produced stronger results. These nine compounds were free of oral toxicity as evaluated by the Toxicity estimation software. Based on further in vitro, in vivo, and clinical effectiveness trials, these compounds may be used for the prevention or treatment as per the Indian system of traditional medicines.
