Synthesis, Characterization, and Carbonic Anhydrase Inhibitory Properties of Silver(I) Complexes of Benzimidazole Derivatives

Abstract

Abstract:The antimicrobial properties of silver compounds and biological properties ofbenzimidazole derivatives have been well known for many years. In the present study, in terms oftheir biological potential, six novel silver(I)-N-alkylbenzimidazole derivatives were synthesized inorder to examine their carbonic anhydrase (CA) inhibitory properties. All complexes werecharacterized by the combination of 1H NMR, 13C NMR, mass, FT-IR spectroscopic methods andelemental analyses. The inhibitory properties of all complexes were tested on the esterase activityof human CA I and II (hCA I and hCA II). Acetazolamide was used as a standard. All complexesinhibited the hCA I and hCA II activity in the range of 27.37-29.58 µM and 20.93-27.25 µM,respectively.
