  摘要：

  Orexins play an important role in sleep/wake regulation, and orexin receptor antagonists are a focus of novel therapy for the treatment of insomnia. We identified 27e (TASP0428980) as a potent dual orexin receptor antagonist through the systematic modification of our original designed lead A. We demonstrated the potent sleep-promoting effects of 27e at ip dose of 3 mg/kg in a rat polysomnogram study. 27e exhibited relatively short half-life profiles in rats and dogs. Furthermore, accumulating evidence regarding ADME profiles indicates that the predicted human half-life of 27e should be 1.2-1.4 h. These data indicated that 27e has a short-acting hypnotic property, suggesting that 27e might be useful for treating primary insomnia while exhibiting a low risk of next-day residual somnolence. Thus, 27e and its related compounds should be further evaluated to enable advancement to clinical trials. (C) 2015 Elsevier Ltd. All rights reserved.
