compounds potentially capable of releasing both aspirin and nitric oxide in vivo. A series of nitrate-bearing alkyl esters of aspirin were prepared based on the choline ester template preferred by human plasma butyrylcholinesterase. The degradation kinetics of the compounds were followed in human plasma solution. All compounds underwent hydrolysis rapidly (t(1/2) approximately 1min) but generating
本文中,我们探讨了硝基阿司匹林的一些设计,这些化合物可能在体内释放阿司匹林和一氧化氮。基于人血浆丁酰胆碱酯酶优选的胆碱酯模板,制备了一系列阿司匹林的含硝酸烷基酯。在人血浆溶液中跟踪化合物的降解动力学。所有化合物均迅速水解(t(1/2)约1分钟),但仅生成相应的水杨酸硝基酯。一个例外是,N-丙基,N-硝基氧乙基氨基乙醇酯以摩尔计产生9.2%的阿司匹林,表明如果可以对活化酶的要求进行适当的认知,就可以实现硝基阿司匹林的目标。即使阿司匹林的释放量很低,
