Abstract
The global spread of the COVID-19 pandemic caused by the etiological agent, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), triggered researchers to identify and develop novel antiviral therapeutics. Herein, we report a new molecule 2-hydroxy-1,2-diphenylethanone N(4)-methyl-N(4)-phenyl thiosemicarbazone (BMPTSC), as a potential inhibitor of SARS-CoV-2. BMPTSC was synthesized, characterized by IR and NMR studies, and the structural parameters were analyzed computationally by B3LYP/cc-pVDZ method. Molecular docking studies were performed to get insights into the energetics and compatibility of BMPTSC against various SARS-CoV-2 drug targets. The best docking poses of target protein-BMPTSC complex structures were further subjected to molecular dynamics (MD) simulations. Molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) calculations on the binding of BMPTSC with the target proteins viz. spike glycoprotein and ACE-2 protein showed energy values of -179.87 and -145.61 kJ/mol, respectively. Moreover, BMPTSC obeys Lipinski's rule, and further in silico assessment of oral bioavailability, bioactivity scores, ADME, drug-likeness, and medicinal chemistry friendliness suggests that this molecule is a promising candidate for the COVID-19 drug discovery process.
