Özet

Here, we report the synthesis, characterization, and biological activities of a series of benzimidazolium salts bearing the trifluoromethylbenzyl group. All benzimidazolium salts were characterized by using nuclear magnetic resonance (NMR) (1H NMR and 13C NMR), Fourier transform-infrared spectroscopy, and elemental analysis techniques. The crystal structures of some of these compounds were obtained by the single-crystal X-ray diffraction method. Furthermore, the acetylcholinesterase (AChE) and α-glycosidase (α-Gly) enzyme inhibition activities of these compounds were investigated. The obtained results revealed that 2e, with Ki value of 1.36 ± 0.34 µM against AChE and 3d with Ki value of 91.37 ± 10.38 µM against α-Gly, were the most potent compounds against both assigned enzymes. It should be noted that most of the synthesized compounds were more potent than standard inhibitor tacrine (TAC) against AChE. In silico studies, we focused on compound 2e, 3d, 3e, and 3f as potent inhibitors of AChE and α-Gly, the compound 2e showed good binding energy (−10.23 kcal/mol), among the three selected compounds and positive control (−10.18, −10.08, and −7.37 kcal/mol for 3d, 3f, and TAC, respectively). Likewise, as a result of the same compounds against the α-Gly enzyme, the compound 3d had the highest binding affinity (−8.39 kcal/mol) between the four selected compounds and the positive control (−8.27, −8.10, −8.06, and −7.53 kcal/mol for 3f, 3e, 2e, and acarbose, respectively). From the absorption, distribution, metabolism, excretion, and toxicity analyses, it can be concluded that the compounds under consideration exhibited more drug-likeness properties in the prediction studies compared to positive controls.
