3-Benzamido, Ureido and Thioureidoimidazo[1,2-a]pyridine Derivatives as Potential Antiviral Agents

Abstract

This work reports the synthesis and the antiviral activities of 3-benzamido, 3-phenylureido and 3-phenyl-thioureido derivatives in the imidazo[1,2-a]pyridine series. The structure was proven by NMR spectroscopy. The synthesized compounds were evaluated against a large number of viruses. The 3-phenylthioureido derivative 7 showed moderate activity against human cytomegalovirus (HCMV) in vitro. The crystallographic data for 8 are also reported and explain the absence of activity against human immunodeficiency virus (HIV).
