As part of our efforts to characterize more fully the structural features of the monoamine oxidase (MAO) A and B active sites, we have examined the substrate and inhibitor properties of several 1-methyl- and 1-cyclopropyl-4-aryl-1,2,3,6-tetrahydropyridine derivatives with the human placental A and beef liver B forms of the enzyme. We find that the 4-(2-phenylphenyl) analog 23 exhibits a high activity
为了更全面地表征单胺氧化酶(MAO)A和B活性位点的结构特征,我们检查了几种1-甲基和1-环丙基-4-芳基-1的底物和抑制剂特性, 2,3,6-四氢吡啶衍生物具有人胎盘A和牛肝B形式的酶。我们发现4-(2-苯基苯基)类似物23对MAO-A表现出高活性和选择性,而4-(3-苯基苯基)类似物22仅对MAO-B表现出活性。用一系列基于N-环丙基机理的灭活剂观察到与N-甲基系列相似的选择性。
