NK1 receptor antagonists a new series of suitably substituted C-phenylpiperazine derivatives was identified by an appropriate chemical exploration of related N-phenylpiperazine analogues, with the specific aim to maximize their in vitro affinity and optimize in parallel their pharmacokinetic profile. Among the compounds synthesized, 2-(S)-(4-fluoro-2-methylphenyl)piperazine-1-carboxylic acid [1-(R)-(3
为了发现新的类似药物的NK 1受体拮抗剂,通过对相关的N-苯基哌嗪类似物进行适当的化学探索,鉴定了一系列新的适当取代的C-苯基哌嗪衍生物,其具体目的是最大程度地提高它们的体外亲和力并同时优化其药代动力学概况。在合成的化合物中,鉴定出2-(S)-(4-氟-2-甲基苯基)哌嗪-1-甲酸[1-(R)-(3,5-双三氟甲基苯基)乙基]甲酰胺(vestipitant)作为最强效和选择性的NK 1之一有史以来发现过的受体拮抗剂,表现出适当的药代动力学性质和体内活性。根据其临床前概况,选择该化合物作为候选药物。
