Molecular docking of sucrase-isomaltase with ligand deacetylbisacodyl when subjected to docking analysis using docking server, predicted in-silico result with a free energy of -3.36 Kcal/mol which was agreed well with physiological range for protein-ligand interaction, making bisacodyl probable potent anti-isomaltase molecule. According to docking server Inhibition constant is 5.98Mm. which predicts that the ligand is going to inhibits enzyme and result in a clinically relevant drug interaction with a substrate for the enzyme. Hydrogen bond with bond length 3.45is formed between Pro 64 (A) of target and of ligand, which is again indicative of the docking between target and ligand. Excellent electrostatic interactions of polar, hydrophobic, pi-pi and Van der walls are observed. The proteinligand interaction study showed 6 amino acid residues interaction with the ligand.

Atrial fibrillation (AF) stands the most widely recognized kind of clinical arrhythmia. Right now accessible anti-Atrial Fibrillation drugs are restricted by just moderate adequacy and an unfavorable safety profile. There is a perceived requirement for enhanced antiarrhythmic agents including activities that are specific for the fibrillating atrium. Therefore, it is of interest to design an appropriate medication for the disease Atrial Fibrillation using Molecular Docking techniques through protein-ligand interaction analysis. Hence, we document the Molecular docking analysis of natriuretic peptide receptor-C towards the design of potential Atrial Fibrillation inhibitors (Aprindine, Inclacumab, and Budiodarone) with the most favorable binding features for further consideration. This study centers around the process for drug discovery finding appropriate medication for the disease Atrial Fibrillation by Molecular Docking technique through protein-ligand interaction. The examination uncovered that out of a couple of molecules that were chosen as target, three of them were seen as most reasonable having the least energies compared to the other molecules. Aprindine, which is utilized in arrhythmia patients as a cardiac depressant. Inclacumab, which is an investigational sedate utilized in trials to look at the treatment and evasion of Myocardial Infarction, Peripheral Arterial Disease (PAD), and Coronary Heart Disease. Budiodarone, which is an antiarrhythmic drug at present in clinical preliminaries identified with amiodarone.

Background: Recently novel corona virus disease, COVID-19 caused the outbreak situation of global public health. In this pandemic situation, all the people lives of 212 Countries and Territories have been affected due to partial or complete lockdown and also as a result of mandatory isolations or quarantines. This is due to the non-availability of any secure vaccine. Objective: The present study helps us to identify and screen best phytochemicals as potent inhibitors against COVID-19. Methods: In this paper we choose two standard drugs namely hamamelitannin and rosmarinic acid as a probable inhibitor of pandemic COVID-19 receptor as compared to antimalarial drug hydroxychloroquine, anti-viral drug remdesivir and also baricitinib. This study was done by taking into consideration of molecular docking study, performed with Auto Dock 4.0 (AD4.0). All chemical structures were optimized with Avogadro suite by applying MMFF94 force field and also hamamelitannin, rosmarinic acid were optimized using Gaussian G16 suite of UB3LYP/6-311++G(d,p) basis set. Protein-ligand interaction was visualized by PyMOL software. Results and Discussion: This work has provided an insightful understanding of protein-ligand interaction of hamamelitannin and rosmarinic acid showing comparable binding energies than that of clinically applying probable COVID-19 inhibitors hydroxychloroquine (an anti-malarial drug) and remdesivir (an anti-viral drug). Conclusions: We will expect that if its anti-SARS-CoV-2 activity is validated in human clinical trials, these two drugs may be developed as an effective antiviral therapeutics towards infected patients in this outbreak and pandemic situation of COVID-19.
