identify a series of potent, selective, orally active human Orexin-2 Receptor (OX2R) antagonists, we elucidated structure-activity relationship (SAR) on the 7-position of a benzoxazepine scaffold by utilizing Hammett σp and Hansch-Fujita π value as aromatic substituent constants. The attempts led to the discovery of compound 1m, possessing good in vitro potency with over 100-fold selectivity against OX1R,
在我们的努力,以确定一系列有效的,选择性的,口服活性的人类食欲素-2受体(OX 2 R)拮抗剂,我们通过利用哈米特σ阐明上的苯并氧氮杂骨架的7位上的结构-活性关系(SAR)p和Hansch-藤田的π值作为芳香族取代基常数。这些尝试导致了化合物1m的发现,该化合物具有良好的体外功效,对OX1R的选择性超过100倍,在人和大鼠肝微粒体中具有良好的代谢稳定性,在大鼠中具有良好的口服生物利用度,并且在口服给药时具有大鼠体内的拮抗活性。
