Abstract

A range of heterocycle fused azepines were synthesized in order to find a CNS penetrant, selective 5-HT(2C) agonist for the treatment of incontinence. The pyridazo-azepines such as compound 11 were shown to be potent 5-HT(2C) agonists and have potential for CNS penetration and good in vitro ADME properties but lacked selectivity against 5-HT(2B). Fusing a further heterocycle gave the selective triazolopyrimido-azepines. An example of this series, compound 36, was shown to be potent, selective, metabolically stable in vitro and efficacious in an in vivo model of stress urinary incontinence.

摘要

为了找到一种可穿透中枢神经系统的、选择性的5-HT(2C)激动剂用于治疗尿失禁,合成了一系列杂环稠合氮杂䓬。诸如化合物11的哒嗪并氮杂䓬被证明是强效的5-HT(2C)激动剂,具有穿透中枢神经系统的潜力和良好的体外吸收、分布、代谢和排泄(ADME)特性,但对5-HT(2B)缺乏选择性。进一步稠合一个杂环得到了选择性的三唑并嘧啶并氮杂䓬。该系列的一个例子,化合物36,被证明是强效的、选择性的,在体外代谢稳定,并且在压力性尿失禁的体内模型中有效。
