10(-8) M. Selectivity for the A and B form of MAO was found to depend on the nature of aromatic ring substitution. In general, hydroxyl substitution favored the inactivation of the A form of MAO, while very selective B inhibitors were obtained when the aromatic ring was substituted with a 4-methoxy group. (E)-2-(4-Methoxyphenyl)-3-fluoroallylamine and (E)-2-(3,4-dimethoxyphenyl)-3-fluoroallylamine proved
制备了十七种2-芳基-3-卤代烯丙胺衍生物,并作为单胺氧化酶的抑制剂进行了评估(MAO,EC 1.4.3.4)。这些化合物的合成是由α-甲基苯乙烯或环取代的苯基乙酸衍生物完成的。除了一个例外,发现这些2-芳基烯丙基胺是酶激活的,不可逆的MAO抑制剂。最有效的抑制剂是(E)-2-苯基-3-氟烯丙胺的环取代衍生物,IC50值在10(-6)到10(-8)M之间。发现对A和B形式的MAO有选择性取决于芳环取代的性质。通常,羟基取代有利于MA形式的A形式的失活,而当芳环被4-甲氧基取代时,获得的选择性非常强。
