Synthesis of different thio-scaffolds bearing sulfonamide with subnanomolar carbonic anhydrase II and IX inhibitory properties and X-ray investigations for their inhibitory mechanism.Bioorg Chem. 2018 12; 81:642-648.BC
Several new molecules with different thio-scaffolds were designed, synthesised, and evaluated biologically as inhibitors of Carbonic Anhydrases (CAIs). The structure-activity relationship analysis identified thioether derivatives, here reported, as a potent and selective CAIs against hCA II and hCA IX. High resolution X-ray structure of inhibitor bound hCA II revealed extensive interactions with the hydrophobic pocket of active site and provided molecular insight into the binding properties of these new inhibitors.
