New 1,2,3-triazole derivatives as acetylcholinesterase and carbonic anhydrase inhibitors: Synthesis, molecular docking, and solubility

Efeoglu, Cagla | Yabalak, Erdal | Nural, Yahya

In this study, a series of new 1,2,3-triazole derivatives were synthesized in 84-93 % yield using copper-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry and characterized by 1H/13C NMR, FT-IR, and HRMS analyses. The synthesized compounds (4a-h) were evaluated for their inhibitory activities against human carbonic anhydrase isoforms I and II (hCA I and hCA II) and acetylcholinesterase (AChE), which are clinically relevant targets in neurological and metabolic disorders. Among them, compounds 4f and 4g exhibited the most potent dual inhibitory activities. Compound 4f showed KI values of 144.30 nM for hCA II and 205.10 nM for AChE, while compound 4g exhibited KI values of 239.10 nM for hCA II and 125.90 nM for AChE. These values demonstrate that 4f and 4g are more effective than ...
