Coronavirus Inhibitory Activity of Tamarind Indica

Abstract

SARS-COVID-19 is an infectious disease, the causative agent Caroni virus. WHO announced the pandemic on 3rd November 2020 to the whole world. Severe Acute Respiratory Syndrome COVID-19 is an infectious disease globally declared a pandemic by WHO. There is a need to find the proper medication for recovery. The study uses the molecular docking method to predict the anti-covid activity of plant phytoconstituents of Tamarind indica. Molecular docking techniques were accomplished to search the binding pattern of plant phytoconstituents of T. indica against the crystal structure SARS-CoV-2 enzyme (PDB ID: 6LU7) with the help of PyRx virtual screening software to study the amino acid interaction and inhibitory potential of phytoconstituents of T. indica. In addition, we performed a pharmacokinetic and toxicological study of plant phytoconstituents of T. indica using SwissADME and the pkCSM online server. The phytoconstituents of Plant T. indica docking results proposed that apigenin (-7.8 kcal/mol), epicatechin (-7.1 kcal/mol) and taxifolin (-7.5 kcal/mol) show the best binding energy as compared to favipiravir (-5.2 kcal/mol). The phytoconstituents exposed promising interaction with amino acid residue, leading to an inhibitory effect against the SARS-CoV-2 enzyme (PDB ID: 6LU7). Further, ADMET studies showed that pharmacokinetics and toxicological parameters are within acceptable limits. In silico study revealed that the phytochemicals of T.indica show promising inhibitory results against the SARS-CoV-2 enzyme (PDB ID: 6LU7). Moreover, the traditional benefits of T.indica were clinical treatment and drug discovery.
