Fe+3 (1,10-phenanthroline)3 as the electron acceptor] and HAT pathway (using the tert-butoxyl radical as the hydrogen atom acceptor). The rates of oxidation and deuterium isotope effects observed with these compounds were similar with the two model reactions. Consequently, unlike their utility in modeling the related cytochrome P450 catalyzed alpha-carbon oxidation of N,N-dimethylaniline derivatives
已经提出了MAO-B催化的胺的α-碳氧化可通过单电子转移(SET)或氢原子转移(HAT)途径进行。为了试图区分这些途径,我们使用化学模型检查了一系列4-取代的1-甲基-1,2,3,6-四氢吡啶衍生物(为MAO-B底物的化合物)的α-碳氧化SET途径[使用Fe + 3(1,10-菲咯啉)3的PF-6盐作为电子受体]和HAT途径(使用叔丁氧基作为氢原子受体)。用这些化合物观察到的氧化和氘同位素速率与两个模型反应相似。因此,与它们在建模相关细胞色素P450催化的N,N-二甲基苯胺衍生物的α-碳氧化中的用途不同,
