A series of 2-aryl pyridine C-region derivatives of 2-(3-fluoro-4-methylsulfonylaminophenyl)propanamides were investigated as hTRPV1 antagonists. Multiple compounds showed highly potent TRPV1 antagonism toward capsaicin comparable to previous lead 7. Among them, compound 9 demonstrated anti-allodynia in a mouse neuropathic pain model and blocked capsaicin-induced hypothermia in a dose-dependent manner
研究了一系列 2-(3-氟-4-甲基磺酰基氨基苯基) 丙酰胺的 2-芳基吡啶 C 区衍生物作为 hTRPV1 拮抗剂。多种化合物显示出与之前的铅 7 相当的对辣椒素的强效 TRPV1 拮抗作用。其中,化合物 9 在小鼠神经性疼痛模型中表现出抗异常性疼痛,并以剂量依赖性方式阻断辣椒素诱导的体温过低。9 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。
