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。
