The spread of novel coronavirus strain, Severe Acute Respiratory Syndrome 2 (SARS-CoV-2) causes Coronavirus disease (COVID-19) has now spread worldwide and effecting the entire human race. The viral genetic material is transcripted and replicated by 3 C-like protease, as a result, it is an important drug target for COVID-19. Hydroxychloroquine (HCQ) report promising results against this drug target so, we perform molecular docking followed by MD-simulation studies of HCQ and modelled some ligand (Mod-I and Mod-II) molecules with SARS-CoV-2-main protease which reveals the structural organization of the active site residues and presence of a conserve water-mediated catalytic triad that helps in the recognition of Mod-I/II ligand molecules. The study may be helpful to gain a detailed structural insight on the presence of water-mediated catalytic triad which could be useful for inhibitor modelling.
