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
在这项研究中,合成了几种新型的磺酰胺,并评估了它们的乙酰胆碱酯酶(AChE)和人碳酸酐酶I和II同工酶(hCA I和II)抑制谱。甲氧基苯乙酮的还原胺化用于胺的合成。在BnOH存在下,将胺与氯磺酰基异氰酸酯(CSI)转化为氨基磺酰基氨基甲酸酯。Pd-C催化氨磺酰氨基甲酸酯的氢解反应得到磺酰胺。这些新颖的化合物是细胞质hCA I和hCA II的良好抑制剂,hCA I的K i值为45.9±8.9–687.5±84.3 pM ,hCA II的K i值为48.80±8.2–672.2±71.9 pM。还研究了合成的新型化合物对AChE的抑制作用。该ķ我这些化合物的AChE值在4.52±0.61–38.28±6.84 pM范围内。这些结果表明,HCA I,II,和乙酰胆碱酯酶被有效利用新颖sulfamoylcarbamates抑制17 - 21个磺酰胺衍生物22 - 26。所有研究的化合物都停靠在相
