Certain (arylsulfonyl)urea hypoglycemic drugs exemplified by chlorpropamide (CP) are known to interact pharmacologically with alcohol (ethanol) to elicit a chlorpropamide-alcohol flushing (CPAF) reaction that is reminiscent of the disulfiram-ethanol reaction (DER). In the present structure-activity study, designed to elucidate the mechanism of inhibition of aldehyde dehydrogenase (AlDH) by CP, we discovered
已知某些以氯丙酰胺(CP)为例的(芳基磺酰基)脲降糖药在药理上与酒精(乙醇)相互作用,以引起氯丙酰胺-酒精冲洗(CPAF)反应,让人联想到二硫仑-乙醇反应(DER)。在本结构活性研究中,旨在阐明CP抑制醛脱氢酶(AlDH)的机制,我们发现CP 2a的N1-甲氧基衍生物是体内AlDH的强效抑制剂,其活性与C2a的活性相似。 N1-乙基衍生物2b。2a和2b都可以非酶释放正丙基异氰酸酯(一种已知的AlDH抑制剂)。但是,在结构上类似于2a的(芳基磺酰基)氨基甲酸酯也是AlDH的活性抑制剂,而相应的2b(芳基磺酰基)氨基甲酸酯类似物却没有活性。
