OpenAlex İngilizce

Abstract The present study focused on the synthesis and characterization of novel pyrazole carboxamide derivatives ( SA1‐12 ). The inhibitory effect of the compounds on cholinesterases (ChEs; AChE and BChE) and carbonic anhydrases ( h CAs; h CA I and h CA II) isoenzymes were screened as in vitro . These series compounds have been identified as potential inhibitors with a K I values in the range of 10.69±1.27–70.87±8.11 nM for hCA I, 20.01±3.48–56.63±6.41 nM for hCA II, 6.60±0.62‐14.15±1.09 nM for acetylcholinesterase (AChE) and 54.87±7.76–137.20 ±9.61 nM for butyrylcholinesterase (BChE). These compounds have a more effective inhibition effect when compared to the reference compounds. In addition, the potential binding positions of the compounds with high affinity for ChE and hCAs were demonstrated by in silico methods. The results of in silico and in vitro studies support each other. As a result of the present study, the compounds with high inhibitory activity for metabolic enzymes, such as ChE and hCA were designed. The compounds may be potential alternative agents used as selective ChE and hCA inhibitors in the treatment of Alzheimer′s disease and glaucoma.
