The synthesis of 2-(4-fluoro-3-hydroxyphenyl)ethylamine (26) and of some N,N-dialkyl derivatives (27-30) starting from 4-fluoro-3-hydroxytoluene and their in vitro binding affinities for dopamine (DA) receptor are reported. The amine 26 can be regarded as a molecular modification of DA in which the para hydroxyl group is replaced by fluorine. The new compounds 26-30 were evaluated for their affinity
从4-氟-3-羟基甲苯开始合成2-(4-氟-3-羟基苯基)乙胺(26)和一些N,N-二烷基衍生物(27-30)及其对多巴胺的体外结合亲和力(报道了DA)受体。胺26可以被认为是DA的分子修饰,其中对羟基被氟取代。通过置换[3H] SCH 23390(D-1选择性)和[3H]哌酮(D-2选择性),评估了新化合物26-30对D-1和D-2 DA受体亚型的亲和力。胺26对D-1和D-2结合位点的亲和力比DA低约2倍。氨基被乙基,正丙基和2-苯基乙基取代会降低对D-1结合位点的亲和力,但会大大增强D-2结合位点的有效性。N-乙基-(28)和Nn-丙基-N-(2-苯基乙基)-2-(4-氟-3-羟基苯基)乙胺(30)是该系列中最有效的成员,对D-具有高选择性2个结合位点。Nn-丙基-N-(2-苯基乙基)-2-(3-氟-4-羟基苯基)乙胺异构体(31)观察到类似的效果,其对D-2位点的选择性是对D-1位
