临床候选4- [2-(5-氨基-1 H-吡唑-4-基)-4-氯苯氧基] -5-氯-2-氟-N -1,3-噻唑-4-基苯磺酰胺(PF)的发现-05089771):作为Na V 1.7选择性抑制剂的二芳基醚芳基磺酰胺的设计和优化
摘要:
描述了一系列酸性二芳基醚杂环磺酰胺,它们是有效的亚型选择性Na V 1.7抑制剂。早期铅物质的优化集中在消除结构警报,改善代谢稳定性和减少细胞色素P450抑制性驱动的药物相互作用方面,以实现临床前体外特性的理想平衡。由于对非代谢途径的清除,临床前物种中的清除程度可变以及随后的低置信度人类药代动力学预测的担忧,导致决定进行人类微剂量研究以确定临床药代动力学。描述了临床前PK和临床人微剂量PK数据的设计策略和结果,从而发现了第一个亚型选择性Na V1.7抑制剂临床候选物PF-05089771(34),其与电压感测域中的位点结合。
