Abstract

A series of 2-alkyl/alkenyl pyridine C-region derivatives of 2-(3-fluoro-4-methylsulfonylaminophenyl)propanamides were investigated as hTRPV1 antagonists. Multiple compounds showed excellent and stereospecific TRPV1 antagonism with better potency than previous lead 2. Among them, compound 15f demonstrated a strong analgesic profile in a rat neuropathic pain model and blocked capsaicin-induced hypothermia in a dose-dependent manner. Docking analysis of (S)-15f with our hTRPV1 homology model provided insight into its specific binding mode.

摘要

研究了一系列2-(3-氟-4-甲基磺酰氨基苯基)丙酰胺的2-烷基/烯基吡啶C区域衍生物作为hTRPV1拮抗剂。多种化合物表现出优异的、立体特异性的TRPV1拮抗作用,效力优于先前的先导化合物2。其中,化合物15f在大鼠神经性疼痛模型中表现出强烈的镇痛作用,并以剂量依赖的方式阻断辣椒素诱导的体温过低。(S)-15f与我们的hTRPV1同源模型的对接分析揭示了其特定的结合模式。
