The synthesis of original imidazo[1,2-a]pyridines bearing a thioether side chain at the 3 position and their antiviral activity are reported. From the synthesized compounds, 4, 15, and 21 were highly active against human cytomegalovirus with a therapeutic index superior to 150. These compounds also showed pronounced activity against varicella-zoster virus. Their structure-activity relationship is discussed.
