action agent was N-(N, N-diethylcarbamoyl)-O-methylbenzenesulfohydroxamic acid (5c), which was postulated to release diethylcarbamoylnitroxyl (9), a highly potent diethylcarbamoylating/nitroxylating agent, following metabolic O-demethylation in vivo. The dual action inhibition of AlDH exhibited by 1d, and especially 9, constitutes a merger of the mechanism of action of the alcohol deterrent agents, disulfiram
在N,N-二乙基氨基甲酰基的羟基上官能化苯甲磺酸异羟肟酸(Piloty's acid),羟胺氮被乙酰基(1a),新戊酰基(1b),苯甲酰基(1c)和乙氧基羰基(1d)取代。只有化合物1d体外抑制了酵母醛脱氢酶(AlDH)(IC(50)169 microM)。当对大鼠给药时,1d乙醇攻击后1d会显着提高血液乙醛水平,因此在体内可作为AlDH的二乙基氨基甲酰化/亚硝酰化的双重作用抑制剂。一种更有效的双作用剂是N-(N,N-二乙基氨基甲酰基)-O-甲基苯磺基异羟肟酸(5c),假定它在体内代谢O-去甲基化后释放出二乙基氨基甲酰硝基氧(9),一种高效的二乙基氨基甲酰化/硝基氧化剂。 。
