Abstract
A series of substituted pyrazole compounds (1-8 and 9a, b) were synthesized and their structure was characterized by IR, NMR, and Mass analysis. These obtained novel pyrazole derivatives (1-8 and 9a, b) were emerged as effective inhibitors of the cytosolic carbonic anhydrase I and II isoforms (hCA I and II) and acetylcholinesterase (AChE) enzymes with Ki values in the range of 1.03 ± 0.23-22.65 ± 5.36 µM for hCA I, 1.82 ± 0.30-27.94 ± 4.74 µM for hCA II, and 48.94 ± 9.63-116.05 ± 14.95 µM for AChE, respectively. Docking studies were performed for the most active compounds, 2 and 5, and binding mode between the compounds and the receptors were determined.
