STRUCTURE MODIFICATION: EFFECT OF LIPOPHILIC, ELECTRONIC, AND STERIC PARAMETERS OF N-BENZOYLN'-PHENYLTHIOUREA COMPOUNDS ON ANTIVIRAL ACTIVITY OF COVID-19 BY IN SILICO

N-benzoyl-N'-phenylthiourea (BFTU) compound is similar to amprenavir derivatives in the urea compound, chloroquine -NH group, and benzene ring, which a potent antiviral. This study evaluated effect of lipophilic, electronic, steric parameters BFTU on antiviral activity Covid-19. In silico docking using Autodock 4.2 confirm pkCSM webserver predict bioavailability toxicity. The SARS-CoV-2 receptor was binding pocket with Protein Data Bank (PDB) code 6LU7. Two three dimensions were generated Marvin Sketch 20.4 UCSF Chimera. Steric affected more than lipophilic electronic parameters. A linear relationship obtained steric, activity, non-linear best predicted for N-benzoyl-N'-2,4-dichloro-phenylthiourea score -9.12 kcal/mol. compounds are as Covid-19 compare reference drugs.
