Some pyrazoles derivatives: Potent carbonic anhydrase, α-glycosidase, and cholinesterase enzymes inhibitors

Abstract

A series of substituteed pyrazol-4-yl-diazene derivatives were found to be effective inhibitors against α-glycosidase, cytosolic carbonic anhydrase I and II isoforms (hCA I and II), butyrylcholinesterase (BChE), and acetylcholinesterase (AChE) with Ki values in the range of 33.72 ± 7.93 to 90.56 ± 27.52 nM for α-glycosidase, 1.06 ± 0.16 to 9.83 ± 0.74 nM for hCA I, 0.68 ± 0.12 to 7.16 ± 1.14 nM for hCA II, 44.66 ± 10.06 to 78.34 ± 17.83 nM for AChE, and 50.36 ± 13.88 to 88.36 ± 20.03 nM for BChE, respectively. Recently, inhibition of these metabolic enzymes has been considered as a promising factor for pharmacologic intervention in a diversity of disturbances, such as diabetes, glaucoma, obesity, epilepsy, cancer, and neurodegenerative diseases.
