A series of 2-thio pyridine C-region analogues of 2-(3-fluoro-4-methylsulfonylaminophenyl)propanamides were investigated as hTRPV1 antagonists. Among them, compound 24S showed stereospecific and excellent TRPV1 antagonism of capsaicin-induced activation. Further, it demonstrated strong anti-allodynic in a rat neuropathic pain model. Consistent with its action in vitro being through TRPV1, compound 24S blocked capsaicin-induced hypothermia in mice. Docking analysis of 24S with our hTRPV1 homology model was performed to identify its binding mode.
研究了一系列 2-(3-氟-4-甲磺酰氨基苯基)丙酰胺的 2-硫代吡啶 C-区域类似物,作为 hTRPV1 拮抗剂。其中,化合物 24S 对辣椒素诱导的激活表现出立体特异性和优异的 TRPV1 拮抗作用。此外,它在大鼠神经病理性疼痛模型中表现出强烈的抗痛觉过敏作用。与体外作用一致,化合物 24S 阻断了小鼠辣椒素诱导的体温过低。用我们的 hTRPV1 同源模型进行了 24S 的对接分析,以确定其结合模式。
