Several 3-carbonyl (1–26), 3-acyl (27–52), and 3-carboxyhydrazido (53–58) coumarins have been synthesized in high yields (72–99%) and tested in vitro for their human monoamine oxidase A and B (hMAO-A and hMAO-B) inhibitory activity. Different substituents on the coumarin nucleus were evaluated for their effect on biological activity and isoform selectivity. Substitution at position C7 of the 3-ethyl
几个-3-羰基(1 - 26),3-酰基(27 - 52),和3- carboxyhydrazido(53 - 58)香豆素已经以高收率(72-99%)合成并测试在体外对它们的人类单胺氧化酶A和B(hMAO-A和hMAO-B)的抑制活性。评价了香豆素核上的不同取代基对生物活性和同工型选择性的影响。对于使用IC 50获得高效且选择性的hMAO-B抑制剂而言,在3-乙酯香豆素环的C7位取代或在C3引入肼基取代基很重要。值在纳摩尔范围内。一些衍生物也进行了稳定性测试,在体外没有化学裂解。
