Abstract

In this study, several novel sulfamides were synthesized and evaluated for their acetylcholine esterase (AChE) and human carbonic anhydrase I, and II isoenzymes (hCA I and II) inhibition profiles. Reductive amination of methoxyacetophenones was used for the synthesis of amines. Amines were converted to sulfamoylcarbamates with chlorosulfonyl isocyanate (CSI) in the presence of BnOH. Pd-C catalyzed hydrogenolysis of sulfamoylcarbamates afforded sulfamides. These novel compounds were good inhibitors of the cytosolic hCA I, and hCA II with Ki values in the range of 45.9±8.9-687.5±84.3 pM for hCA I, and 48.80±8.2-672.2±71.9pM for hCA II. The inhibitory effects of the synthesized novel compounds on AChE were also investigated. The Ki values of these compounds were in the range of 4.52±0.61-38.28±6.84pM for AChE. These results show that hCA I, II, and AChE were effectively inhibited by the novel sulfamoylcarbamates 17-21 and sulfamide derivatives 22-26. All investigated compounds were docked within the active sites of the corresponding enzymes revealing the reasons of the effective inhibitory activity.
