Synthesis and Biological Properties of Some 3‐Heterocyclic Substituted Coumarins

Abstract

Abstract 2‐Mercaptobenzimidazoles and 3‐phenyl‐5‐mercapto‐ s ‐triazoles have been reacted with 3‐(bromoacetyl)coumarin to get the fused thiazoles. Antiinflammatory studies indicate that the introduction of a nitro group at the para position of the phenyl ring enhances the activity to a great extent. Antibacterial and antifungal activities were also tested.
