Abstract

A series of new ortho-phenylenediamine derivatives were designed. The crystal structure of the main protease monomer was used as a target protein for molecular docking of ortho- phenylenediamine derivatives and a protein-ligand interaction analysis was performed using Auto Dock 4.2 software. Based on the docking score and after additional three-dimensional similarity analysis, NHM7 [(10,10’-((1E,1’E)-(1,2-phenylenebis(azanylylidene))bis(methanylylidene))bis(anthracen-9(8aH)-one)] had the highest binding energy. The calculated binding energy of ortho- phenylenediamine indicated effective binding of the proposed inhibitors to COVID-19 proteinase.
