Monoamine oxidase B metabolizes 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP; 1) first to 1-methyl-4-phenyl-2,3-dihydropyridinium salt (MPDP+; 5), and then to 1-methyl-4-phenylphridinium salt (MPP+; 7). Chemical synthesis of MPDP+ and its 5-methyl analog 6 was accomplished from the N-oxides 3 and 4 of MPTP and its 5-methyl analog, respectively, by a Polonovski reaction. Oxidation of MPDP+ to
单胺氧化酶B首先将1-甲基-4-苯基-1,2,3,6-四氢吡啶(MPTP; 1)代谢为1-甲基-4-苯基-2,3-二氢吡啶鎓盐(MPDP + ; 5),然后然后制得1-甲基-4-苯基phr鎓盐(MPP +;7)。MPDP +及其5-甲基类似物6的化学合成分别通过Polonovski反应由MPTP及其5-甲基类似物的N-氧化物3和4完成。用空气将MPDP +氧化为MPPM +,并通过Pt催化剂大大加速了氧化。减少MPDP +用NaBH 4的MPP +提供了MPTP。
