to D(2)-like receptor binding of the 4,5-dihydrobenzo[g]indole portion of the molecule was examined. From these studies, compound 2k, 2-chloro-N-(1-ethyl-2-pyrrolidinylmethyl)-5,6-dihydro-4H-benzo[6,7]cyclohepta[b]pyrrole-3-carboxamide, was found to possess a potent affinity for D(2)-like receptors. Behavioural tests in rats have shown that this compound reduces the hyperactivity induced by amphetamine
N-(1-乙基-2-吡咯烷基甲基)-4,5-二氢-1H-苯并[g]吲哚-3-羧酰胺(2a)(一系列2-氨基甲基吡咯烷基的代表术语)的各种新衍生物和结构类似物合成具有良好的D(2)-样亲和力的4,5-二氢苯并[g]吲哚甲酰胺,并评估它们在体外与多巴胺D(2)-样受体结合的能力。检查了分子的4,5-二氢苯并[g]吲哚部分对D(2)样受体结合的结构贡献。从这些研究中,发现化合物2k 2-氯-N-(1-乙基-2-吡咯烷基甲基)-5,6-二氢-4H-苯并[6,7]环庚[b]吡咯-3-甲酰胺对D(2)样受体具有强大的亲和力。在大鼠中进行的行为测试表明,该化合物可减轻由苯丙胺引起的机能亢进,苯丙胺是所有抗精神病药物共有的特性,剂量不能诱发僵直性僵直,这种作用预示着人类锥体外系副作用。其他化合物表现出中等的(2c,2h和2j)或对D(2)样受体没有亲和力。
