demonstrated that compounds with acyclic amide-containing sidechains displayed exceptional binding and functional potency, but negligible CNS penetration. Related analogs with acyclic benzylamine-containing sidechains showed greatly improved CNS exposure, but suffered in functional potency. In this report, we demonstrate that cyclization of these benzylic amine sidechains affords compounds that combine
先前对2-氨基-8-烷氧基喹啉MCHr1拮抗剂的SAR研究表明,具有无环酰胺基侧链的化合物显示出优异的结合力和功能效能,但CNS渗透率可忽略不计。具有无环苄基胺侧链的相关类似物显示大大改善了中枢神经系统的暴露,但功能效力受到影响。在这份报告中,我们证明了这些苄基胺侧链的环化作用提供了结合了这类拮抗剂中效价和CNS渗透力最佳元素的化合物。化合物21举例说明了这一点,该化合物具有亚纳摩尔级的MCHr1结合亲和力,良好的功能效能和24小时内出色的CNS暴露。
