electron-withdrawing groups. Finally, the enantiomers of 14 were resolved via the 1,1'-binaphthyl-2,2'-diyl hydrogen phosphate salts. Although both isomers were partial DA agonists, the (+)-enantiomer had higher intrinsic activity than the (-)-enantiomer. Syntheses were developed that allowed rapid preparation of analogues. An X-ray crystal structure determination of an intermediate identified the (+)-isomer of
新型多巴胺(DA)受体激动剂1,2,3,6-四氢-4-苯基-1-[(3-苯基-3-环己烯-1-基)甲基]吡啶(14)被鉴定。通过合成类似物并评估其多巴胺能,研究了该化合物周围的构效关系。环己烯的取代方式以及将1,2,3,6-四氢-4-苯基吡啶连接到环己烯的链的长度变化。具有1,3-取代模式和一条亚甲基链的化合物14是最有效的。1,2,3,6-四氢-4-苯基吡啶可被其他芳基环胺取代,但活性略有下降。环己烯环上的苯基可以被对位取代;给电子基团比吸电子基团更好的耐受性。最后,通过1,1'-萘基-2,2'-二基磷酸氢盐拆分14个对映体。尽管两种异构体均为部分DA激动剂,但(+)-对映体的固有活性高于(-)-对映体。已开发出允许快速制备类似物的合成物。中间体的X射线晶体结构测定确定14的(+)-异构体具有R构型。在行为测试中发现该化合物名为CI-1007(PD 143188)具有抗精神病样活性。特别
