A series of analogues of N,N-di-n-propyldopamine (DPDA) in which the 3-hydroxyl group was replaced by bioisosteric groups was prepared and evaluated for D1- and D2-receptor affinity. The 3-methane-sulfonamide analogue (18) had a higher affinity for the D2 receptor than DPDA and was more selective for the D2 receptor. The 3-formamide derivative (15) also retained significant D2 affinity. Both of these
制备了一系列N,N-二-正丙基多巴胺(DPDA)的类似物,其中3-羟基被生物等位基团取代,并评估了D1-和D2-受体亲和力。3-甲烷-磺酰胺类似物(18)对D2受体的亲和力高于DPDA,对D2受体的选择性更高。3-甲酰胺衍生物(15)也保留了显着的D2亲和力。这两种化合物在麻醉的大鼠模型中均表现出体内心血管和肾脏特征,与选择性D2受体激动作用相一致。
