Medicinal applications of coumarins bearing azetidinone and thiazolidinone moieties

Abstract

Coumarins (2 H-chromen-2-ones), also known as benzopyran-2-ones, are a family of naturally occurring heterocyclic ring systems that contain a lactone moiety. Coumarins exhibit a wide range of well-studied pharmacological properties. Over the last few decades, as a result of advances in diverse oriented synthetic routes, physicochemical properties and numerous biological activities, coumarins have become globally studied molecules from various synthetic and medicinal chemists. Recently, several bioactive coumarins bearing azetidinone and thiazolidinone moieties have been found to display a range of therapeutic characteristics, including antimicrobial, anticancer, antidiabetic and anti-inflammatory properties. This review offers a brief description of the synthetic methodologies, known bioactivity and structure–activity relationships of coumarins bearing azetidinones and thiazolidinones.
