A series of sulfonamides containing coumarin moieties had been prepared that showed a very interesting profile for the inhibition of two human carbonic anhydrase inhibitors. These compounds were evaluated for their ability to inhibit the enzymatic activity of the physiologically dominant isozymes hCA II and the tumor-associated isozyme hCA IX. The most potent inhibitor against hCA II and IX were compounds 5d (IC50 = 23 nM) and 51 (IC50 = 24 nM), respectively. These sulfonamides containing coumarin moieties may prove interesting lead candidates to target tumor-associated CA isozymes, wherein the CA domain is located extracellularly. Eighteen compounds were scrutinized by CoMFA and CoMSIA techniques of 3D quantitative structure activity relationship. Nine of the compounds were evaluated for cytotoxicity against human macrophage.
