Аннотация
In the current study, a series of pyrazole-sulfonamide derivatives (2-14) were synthesized, characterized, and the inhibition effects of the derivatives on human carbonic anhydrases (hCA I and hCA II) were investigated as in vitro. Structures of these sulfonamides were confirmed by FT-IR, (1)H NMR, (13)C NMR and LC-MS analysis. (1)H NMR and (13)C NMR revealed the tautomeric structures. hCA I and hCA II isozymes were purified from human erythrocytes and inhibitory effects of newly synthesized sulfonamides on esterase activities of these isoenzymes have been studied. The K(i) values of compounds were 0.062-1.278 μM for hCA I and 0.012-0.379 μM for hCA II. The inhibition effects of 7 for hCA I and 4 for hCA II isozymes were almost in nanomolar concentration range.
