Abstract

A series of glycosyl triazol linked 18β-glycyrrhetinic acid (GA) derivatives have been synthesized using 1,3-dipolar cycloaddition reaction of per-O-acetylated glycosyl azide derivatives (4a–h) with propargyl ester of 18β-glycyrrhetinic acid (GA) (2 and 3) following the concept of ‘Click chemistry’. The synthesized triazole derivatives were de-O-acetylated to furnish compounds (7a–h and 8a–c) with free hydroxyl groups in the carbohydrate moieties, which were evaluated for their anticancer potential against human cervical cancer cells (HeLa) and normal kidney epithelial (NKE) cells. GA (1), compound 7d, compound 7g and compound 8c showed promising anticancer activities.
