Reported herein is the design, synthesis, and pharmacologic evaluation of a class of TRPV1 antagonists constructed on a N1-(isoquinolin-5-yl)-N2-phenylpyrrolidine-1,2-dicarboxamide platform that evolved from a 5-aminoisoquinoline urea lead. Advancing the SAR of this series led to the eventual identification of 3b, comprising a p-Br substituted phenyl. In a TRPV1 functional assay, using cells expressing
本文报道的是从5-氨基异喹啉尿素演变而来的N 1-(异喹啉-5-基)-N 2-苯基吡咯烷-1,2-二甲酰胺平台上构建的一类TRPV1拮抗剂的设计,合成和药理学评估。带领。推进该系列的SAR,最终鉴定出了3b,其包含对-Br取代的苯基。在TRPV1功能测定中,使用表达重组人TRPV1通道的细胞,3b显示了由辣椒素(IC 50 = 0.084μM)和质子(IC 50 = 0.313μM)激活的强烈拮抗作用。在初步的镇痛药和体温测试中,3b在辣椒素引起的和热引起的疼痛模型中显示出良好的疗效,并且没有热疗的副作用。基于其优越的特性,3b可被认为是抗伤害性药物进一步开发的主要候选药物。
