Two of the WS phytoconstituents viz. withanolides A and B showing significant binding to selected viral target proteins were subjected to molecular dynamics simulation studies with SARS CoV-2 spike receptor binding domain (PDB ID: 6M0J) and SARS CoV-2 papain like protease (PDB ID: 6W9C), respectively. The playmolecule web platform (https://www.playmolecule.com/SimpleRun/) is publicly available at www.playmolecule.org and uses high-throughput molecular dynamics (HTMD), a python-based framework in order to perform simple molecular-simulation-based drug discovery (Raimondas et al., 2019; Rossell et al., 2017). The MD simulation was run for 3 ns for both SARS-Cov-2 glycoprotein–withanolide A complex and SARS CoV-2 papain like protease-withanolide B complex at 300 K.
