Synthesis and Anti‐Hepatitis B Virus Activity of a Novel Class of Thiazolylbenzimidazole Derivatives

Abstract

Recently, heterocyclic benzimidazole derivatives have been investigated and validated as a promising class of antiviral agents. In this paper, a series of novel thiazolylbenzimidazole derivatives was synthesized and evaluated for their anti-hepatitis B virus (HBV) activity and cytotoxicity on the HepG2.2.15 cell line. Afterwards, the preliminary structure-activity relationship (SAR) was discussed. Compound 8b, with IC(50) = 1.1 µM and SI > 90.9, was the most promising compound and could be selected as a benchmark compound for further investigation.
