In this study, we synthesized a series of new benzimidazole-triazole (6a-6k) derivatives and characterized them by 1 H NMR, 13C NMR, and HRMS. These compounds were evaluated for their inhibitory activity against hCA-I and hCA-II. All the compounds exhibited good hCA-I and hCA-II inhibitory activities with IC50 values in the range of 1.158 µM to 3.48 µM. Among all these compounds, compound 6j, with an IC50 value of 1.288 µM and 1.6197 µM, is the most active against hCA-I and hCA-II, respectively. Compounds 6a-6k were also evaluated for their cytotoxic effects on the L929 mouse fibroblast (normal) cell line. Enzyme inhibition kinetics showed all compounds 6a-6k to inhibit the enzyme by non-competitive. The most active compound 6j was subjected to molecular docking, which revealed their binding interactions with the enzyme’s active site, confirming the experimental findings.
