The substituted benzamides are used clinically both as antipsychotics and as stimulants of gastric motility. The antipsychotic effects are considered to be a consequence of their central dopamine antagonist properties, but there is evidence that the gastric stimulatory effects may be mediated by other mechanisms. Clebopride (3) is a substituted benzamide that although marketed for its stimulatory effects
取代的苯甲酰胺在临床上既用作抗精神病药,又用作胃动力的兴奋剂。抗精神病作用被认为是其中央多巴胺拮抗剂特性的结果,但是有证据表明,胃刺激作用可能是由其他机制介导的。Clebopride(3)是一种取代的苯甲酰胺,尽管因其对胃蠕动的刺激作用而上市,但它也是有效的中枢多巴胺拮抗剂。已合成了酰胺键已被逆转的相应的苯胺化物BRL 20596(4a),发现其缺乏胃刺激活性。但是,有效的中枢多巴胺拮抗剂活性得以保留,表明苯甲酰胺和苯胺对中枢多巴胺受体具有相似的亲和力。讨论了在这些受体上苯甲酰胺和苯甲酰胺采用的构象的含义。也有证据表明,在这类受体上还有一个亲脂性结合位点,N-苄基最适合。
