Abstract

Drug resistance to chemotherapeutic agents paved the way to develop novel synthetic molecules which are active on MDR cancer cell lines. Regio-isomeric imidazo[4,5-b]pyridine analogues were synthesized and evaluated for their cytotoxic activity against a range of cancer cell lines. The structure-activity relationship (SAR) studies of the imidazopyridine analogues are also described. Analogue 6b displayed strong cytotoxicity and good microsomal stability.

Keywords: Chemotherapy; Cytotoxic studies; Imidazo[4,5-b]pyridine analogues; Suzuki coupling.
