Monoamine oxidase (MAO) was shown previously to undergo time-dependent inhibition by 5-(aminomethyl)-3-(4-methoxyphenyl)-2-oxazolidinone (3, X=N, Y=O, R=Me, R'=H), cis- and trans-5-(aminomethyl)-3-(4-methoxyphenyl)dihydrofuran-2(3H)-one (5, R=Me), and 4-(aminomethyl)-1-(4-methoxyphenyl)-2-pyrrolidinone (6, R=Me). Two approaches are taken in this article to test the hypothesis that the cause for this
先前显示单胺氧化酶 (MAO) 会受到 5-(氨基甲基)-3-(4-甲氧基苯基)-2-恶唑烷酮 (3, X=N, Y=O, R=Me, R'= H)、顺-和反-5-(氨基甲基)-3-(4-甲氧基苯基)二氢呋喃-2(3H)-酮(5,R=Me)和4-(氨基甲基)-1-(4-甲氧基苯基) )-2-吡咯烷酮 (6, R=Me)。本文采用两种方法来检验这种抑制的原因是杂环对酶加合物的吸电子稳定性的假设。首先,测量了被抑制酶的再激活率,它们与杂环的吸电子能力的强度定性相关
