Millions of people worldwide suffer from acute or chronic liver inflammation caused by the Hepatitis C virus (HCV). Some inhibitors with metal ion chelating structures have been proven to have good inhibitory activities on non-structural protein 5B (NS5B) polymerase. However, most of the reported metal ion chelators showed poor anti-HCV potency at the cellular level. Hence, authors designed and synthesized a series of 3-hydroxyquinazoline-2,4(1H,3H)-dione derivatives with novel metal ion chelating structures. Few compounds such as compound I, [R = 4-(trifluoromethyl)phenyl, 3-nitrophenyl, benzofuran-2-yl] showed better anti-HCV activities than ribavirin with EC50 values less than 10μM. Compound I [R = benzofuran-2-yl] is currently known as one of the metal ion chelators with the best anti-HCV potency (EC50 = 2.0μM) at the cellular level and has a better therapeutic index (TI > 25) as compared to ribavirin. In the thermal shift assay, the representative compounds 3-hydroxy-7-phenylquinazoline-2,4(1H,3H)-dione and 3-hydroxy-7-(3-nitrophenyl)quinazoline-2,4(1H,3H)-dione increased the melting temperature (Tm) of NS5B protein solution by 1.6°C and 2.1°C, resp., at the test concentration, indicating that these compounds may exert an anti-HCV effect by targeting NS5B. This speculation was also supported by mol. docking studies and UV-visible (UV-Vis) spectrophotometry assay, in which the possibility of binding of 3-hydroxyquinazoline-2,4(1H,3H)-diones with Mg2+ in the NS5B catalytic center was observed
