    Probing the Mechanism of Bioactivation of MPTP Type Analogs by Monoamine Oxidase B: Structure-Activity Studies on Substituted 4-Phenoxy-, 4-Phenyl-, and 4-Thiophenoxy-1-cyclopropyl-1,2,3,6-tetrahydropyridines
    摘要:
    Previous studies have shown that 4-benzyl-1-cyclopropyl-1,2,3,6-tetrahydropyridine is an excellent monoamine oxidase B (MAO-B) substrate (k(cat)/K-M = 1538 min(-1) mM(-1)) although the corresponding 4-phenyl analog displays MAO-B inactivating properties only. This behavior led us to speculate that the pathway for the MAO-B catalyzed oxidation of these tetrahydropyridines may not necessarily proceed via an initial single electron transfer step as proposed by others but rather through an initial alpha-carbon hydrogen atom abstraction step. In the present studies we have examined the interactions of various 4-phenoxy-, 4-phenyl-, and 4-thiophenoxy-1-cyclopropyl-1,2,3,6-tetrahydropyridine derivatives, some of which bear substituents on the phenyl ring. The 4-thiophenoxy- and all of the 4-phenoxytetrahydropyridine derivatives proved to be substrates but not inactivators of MAO-B, while several of the 4-phenyltetrahydropyridine derivatives were inactivators but not substrates. A case of particular interest was 1-cyclopropyl-4-(2-methylphenyl)-1,2,3,6-tetrahydropyridine, which displayed only substrate properties. The results are discussed in terms of two catalytic pathways, one of which involves partitioning of the proposed cyclopropylaminyl radical cation intermediate between cyclopropyl ring opening and proton loss while the second involves partitioning of the parent amine between an initial single electron transfer step, leading to cyclopropylaminyl radical cation formation and enzyme inactivation, and an initial alpha-carbon hydrogen atom abstraction step, leading to an allylic radical and dihydropyridinium product formation.
