By taking advantage of certain features in piperidine 4, we developed a novel series of cyclohexylamine- and piperidine-based benzenesulfonamides as potent and selective Nav1.7 inhibitors. However, compound 24, one of the early analogs, failed to reduce phase 2 flinching in the mouse formalin test even at a dose of 100 mpk PO due to insufficient dorsal root ganglion (DRG) exposure attributed to poor
通过利用
哌啶4中的某些功能,我们开发了一系列新型的基于
环己胺和
哌啶的苯磺酰胺,作为有效的和选择性的Na v 1.7
抑制剂。但是,化合物24是早期的类似物之一,即使在100 mgkPO PO的剂量下,也未能降低小鼠
福尔马林试验中的2期退缩,原因是由于膜通透性差而导致背根神经节(DRG)暴露不足。两种具有改善的膜通透性的类似物在30 mpk PO的剂量下显示出DRG浓度大大增加,但是,令人困惑的是,在
福尔马林试验中,只有其中一种有效。需要更多数据来了解功效和暴露关系之间的脱节。
