A series of (beta-aminoethyl)indolones and related compounds was synthesized and evaluated in vitro as peripheral prejunctional dopaminergic agonists in the field-stimulated isolated perfused rabbit ear artery. 4-[2-(Di-n-propylamino)ethyl]-7-hydroxy-2(3H)-indolone was the most potent compound (ED50 = 2 +/- 0.3 nM) tested, while the related secondary amine 24 and the des-OH derivatives 28 and 34 were
合成了一系列(β-氨基乙基)吲哚酮和相关化合物,并在体外刺激的离体灌流兔耳动脉中作为外围结前多巴胺能激动剂进行了体外评估。4- [2-(二-正丙基氨基)乙基] -7-羟基-2(3H)-吲哚酮是测试的最有效化合物(ED50 = 2 +/- 0.3 nM),而相关的仲胺24和des-OH衍生物28和34的效力略低。使用4-甲氧基苯乙胺和2-甲基-3-硝基苯基乙酸作为合成4-(β-氨基乙基)吲哚酮的起始原料。通过硝化衍生自4-甲氧基苯基乙酸的苯乙胺43制备开环的3-酰基氨基类似物46和47。非活性异构体吲哚酮38、39和41衍生自4-硝基苯乙胺和吲哚酮-6-乙酸。
