ABSTRACT
Synthesized 3-benzyl(phenethyl)benzo[g]quinazolines (1-17) were evaluated in vitro to determine their effects against the anti-hepatitis A virus (HAV) using a cytopathic effect inhibition assay. Of the synthesized compounds, 16 and 17 showed considerably high anti-HAV activity, as indicated by their EC50 values of 27.59 and 18⯵M, respectively, when compared to that of amantadine (37.3⯵M), the standard therapeutic agent. In addition, they exhibited low cytotoxicity as indicated by their CC50 values, 290.63 and 569.45⯵M, respectively. Compounds 1, 2, and 5 exhibited remarkable activity compared to the active compounds (16, 17) and amantadine. The selectivity index (SI) values were calculated and applied as a parameter for classifying the activity of the targets. In addition, molecular docking was performed to rationalize the SAR of the target compounds and analyze the binding modes between the docked-selected compounds and amino acid residues in the active site of the HAV-3C proteinase enzyme.
