Yeni N-benzilbenzimidazol-gümüş(I) komplekslerinin sentezi, karakterizasyonu, karbonik anhidraz ve polifenol oksidaz enzimleri üzerindeki inhibitör özellikleri.

The biological properties of silver complexes are well known but the studies about the enzyme inhibitory properties of them are very rare. On the other hand, it is known that one of the anticancer mechanisms of action of benzimidazole derivatives is enzyme inhibition. Therefore, in this study, five novel N-benzylbenzimidazole-silver(I) complexes were synthesized and fully characterized by ¹H NMR, 13C NMR, IR, mass spectroscopic methods and elemental analyses. The inhibitory properties of the synthesized complexes were tested on the activity of human carbonic anhydrase I - II and polyphenol oxidase, and it was observed that the complexes inhibited the activity of these enzymes with the IC50 values of 29.58-32.65 μM, 21.05-23.65 μM and 30.38-44.45 μM, respectively. We suggest that by also considering the low toxicity of silver compounds to human body at low concentrations, the evaluated complexes in this study are promising agents in the treatment of glaucoma and hyperpigmentation as carbonic anhydrase and polyphenol oxidase inhibitors.
