The synthesis and dopamine agonist activity of some derivatives of trans-6-methyl-7a,8,9,10,11,11a-hexahydro-7H-pyrrolo[3,2,1-gh]- 4,7-phenanthroline (6a-c) are reported. These compounds can be regarded as analogues of ergoline derivatives with the indole nucleus replaced by indolizine. These congeners have been evaluated as inhibitors of prolactin release in vivo. trans-6-Methyl-8-ethyl-7a,8,9,10
反式-6-甲基-7a,8,9,10,11,11a-六氢-7H-吡咯并[3,2,1-gh]-4,7-菲咯啉(6a)的某些衍生物的合成和多巴胺激动剂活性-c)报告。这些化合物可以被认为是麦角灵衍生物的类似物,其中吲哚核被吲哚嗪取代。这些同类物已被评估为体内催乳激素释放的抑制剂。反式-6-甲基-8-乙基-7a,8,9,10,11,11a-六氢-7H-吡咯并[3,2,1-gh]-4,7-菲咯啉(6b)被证明产生剂量依赖的血清催乳素抑制作用在使用的最高剂量下几乎完全消失。尽管有效,但该化合物的功效远不如溴隐亭。8-丙基衍生物6c仅在非常高的剂量下才具有弱活性,而8-甲基衍生物6a被证明是完全无效的。反-4-丙基-1,2,3,4,4a,5,6,10b-八氢-4,7-菲咯啉(7)是六氢吡咯并4,7-菲咯啉的分子简化形式,被证明是新合成的化合物中最有效的。这些结果与先前的研究结果一起表明,在八氢-4,7-
