A series of 6-substituted 3-(pyrrolidin-1-ylmethyl)chromen-2-ones (coumarins) have been synthesized and their inhibitory activity to human monoamine oxidase A (MAO A) and B (MAO B) determined. Incorporation of a basic amino function in the C3 position together with substitution at the C6 position produced novel coumarin compounds with selectivity for the MAO A subtype. Substitution in the C6 position
已经合成了一系列的6-取代的3-(吡咯烷-1-基甲基)铬-2-酮(香豆素),并确定了它们对人单胺氧化酶A(MAO A)和B(MAO B)的抑制活性。在C3位上结合基本氨基官能团以及在C6位上取代产生了对MAOA A亚型具有选择性的新型香豆素化合物。在C6位置被较小的亲水基团取代,例如羟基(19,IC 50 = 1.46μM)或氨基(18,IC 50 = 3.77μM),是MAO A最有效和最具选择性的化合物。这些化合物还显示出优异的水溶性特性。给予化合物18 [6-氨基-3-(吡咯烷-1-基甲基)铬-2--2-]体内在大鼠脑中诱导的典型MAO A抑制神经递质代谢产物特征:3,4-二羟基苯基乙酸(DOPAC)和5-羟基吲哚乙酸(5-HIAA)降低,但3-甲氧基酪胺(3-MT)水平升高。
