In this study, alkynyl–coumarinyl ethers were developed as inhibitors of human monoamine oxidase B (MAO-B). A series of 31 new, ether-connected coumarin derivatives was synthesized via hydroxycoumarins, whose phenolic group at position 6, 7 or 8 was converted by means of the Mitsunobu reaction. The majority of the final products were produced from primary alcohols with a terminal alkyne group. The
在这项研究中,开发了炔基-香豆基醚作为人单胺氧化酶B(MAO-B)的抑制剂。通过羟基香豆素合成了31种新的,与醚连接的香豆素衍生物,该羟基香豆素的6、7或8位酚基通过Mitsunobu反应转化。大多数最终产品是由带有末端炔基的伯醇生产的。就炔基氧基链的结构及其在稠合苯环上的位置以及吡喃-2 H-一部分的3位上的残基而言,对抑制剂进行了优化。发现在位置7的六-5-炔氧基链是特别有利的。在7-己-5-炔氧基香豆素中,3-甲氧基羰基衍生物36被表征为具有IC的双作用抑制剂对MAO-A和MAO-B的50个值小于10 nM,并且3-(4-甲氧基)苯基衍生物44被证明具有强大的抗MAO-B效力(IC 50 = 3.0 nM)和对MAO的选择性-B高于MAO-A(选择性> 3400倍)。
