Özet

In this study, novel dithiocarbamate-sulfonamide derivatives (3a-3k) were synthesized to investigate their inhibitory activity on purified human carbonic anhydrase (hCA) I and II. The IC50 and Ki values of the compounds were calculated to compare their inhibition profiles on hCA I and II isoenzymes. Acetazolamide was used as the standard inhibitor in the enzyme inhibition assay. Compounds 3a, 3e, 3g, 3h, 3j and 3k showed notable inhibitory effects against hCA I and II. Among these compounds, compound 3h was found to be the most active derivate against both the hCA I and II enzymes with Ki values of 0.032 ± 0.001 μM and 0.013 ± 0.0005 μM, respectively. The cytotoxicity of compounds 3a, 3e, 3g, 3h, 3j and 3k toward NIH/3T3 (mouse embryonic fibroblast cell line) was observed and the compounds were found to be non-cytotoxic. Furthermore, molecular docking studies were performed to investigate the interaction types between compound 3h and the hCA I and II enzymes. As a result of this study a novel and potent class of CA inhibitors with good activity potential were identified.
