receptor antagonists (2-SORAs) has been hampered by the lack of orally bioavailable, highly selective small molecule probes. Herein, the discovery and optimization of a novel series of 2,5-diarylnicotinamides as potent and orally bioavailable orexin-2 receptor selective antagonists is described. A compound from this series demonstrated potent sleep promotion when dosed orally to EEG telemetrized rats
由于过去十年中发现的大量生物学和遗传数据,食欲素(或降血糖素)系统已被确定为治疗失眠的新靶标。最近,使用双重(OX 1 R / OX 2R)食欲素受体拮抗剂。但是,由于缺乏口服生物利用度高选择性小分子探针,阻碍了与选择性orexin-2受体拮抗剂(2-SORA)相关的药理学研究。在此,描述了发现和优化作为有效的和口服生物利用的orexin-2受体选择性拮抗剂的2,5-二芳基烟酰胺的新系列。当从脑电图遥测大鼠口服给药时,该系列化合物显示出有效的睡眠促进作用。
The present invention is directed to bipyridyl carboxamide compounds which are antagonists of orexin receptors, and which are useful in the treatment or prevention of neurological and psychiatric disorders and diseases in which orexin receptors are involved. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which orexin receptors are involved.
