design, synthesis, and SAR of dual orexin 1 and 2 receptor antagonists, which were optimized by balancing the antagonistic activity for orexin receptors and lipophilicity. Based on the prototype compound 1, ring construction and the insertion of an additional heteroatom into the resulting ring led to the discovery of orexin 1 and 2 receptor antagonists, which were 3-benzoyl-1,3-oxazinane derivatives. Within
在这里,我们介绍了双orexin 1和2受体拮抗剂的设计,合成和SAR,这些受体拮抗剂通过平衡对orexin受体的拮抗活性和亲脂性进行了优化。基于原型化合物1,环的构建以及在所得环中插入一个额外的杂原子导致发现orexin 1和2受体拮抗剂,它们是3-苯甲酰基-1,3-恶嗪烷衍生物。在这些衍生物中,(-)- 3h具有很高的双重orexin受体拮抗活性和低亲脂性。在大鼠多导睡眠图研究中,化合物(-)- 3h在po剂量为1 mg / kg时表现出有效的促睡眠作用,并具有最佳的PK特性和快速的T max观察到大鼠和狗的半衰期短,表明人的半衰期预计为0.9-2.0 h。因此,(-)- 3h(ORN0829;研究代号TS-142)被选为可行的候选药物,目前正处于临床研究中,以治疗失眠症。
