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

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。
