s Drug Re-purposing from SARS-CoV Led the Identification of Potential Candidate Drug Target and Alternate Drug Molecules Against SARSCoV- 2

Background: SARS-CoV-2 causes COVID19 disease where there are no suitable drugs available. Objective: The objective of the work is to repurpose the drugs prescribed for SARS-CoV as the drugs for the control of SARS-CoV-2. Methods: In this work, we have used homology searches and docking methods for understanding the mechanism of the drugs prescribed for the control of SARS-CoV on SARS-CoV-2. Results: In our analysis, we found that the drugs Benzyl (2-Oxopropyl)carbamate, 2-[(2,4-Dichloro- 5-methyl phenyl)sulfonyl]-1,3-dinitro-5-(trifluoromethyl)benzene, S-[5-(Trifluoromethyl)-4H-1,2,4- triazol-3-YL] 5-(phenylethynyl)furan-2-carbothioate, 4-(Dimethylamino)benzoic acid, which are capable of inhibition of the activity of 3CLPro and prevent the progression of SARS-CoV. Conclusion: In this letter, we describe the findings of the protein ligand interactions between 3CLPro of SARS-CoV, SARS-CoV-2 with Benzyl (2-oxopropyl) carbamate.
