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
研究了一系列 2-(3-fluoro-4-methylsulfonylaminophenyl)propanamides 的 2-烷基/烯基吡啶 C 区衍生物作为 hTRPV1 拮抗剂。多种化合物显示出优异的立体特异性 TRPV1 拮抗作用,其效力优于先前的铅 2。其中,化合物 15f 在大鼠神经性疼痛模型中表现出强大的镇痛作用,并以剂量依赖性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提供了对其特定结合模式的深入了解。
