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
研究了一系列 2-(3-氟-4-甲基磺酰基氨基苯基) 丙酰胺的 2-硫代吡啶 C 区类似物作为 hTRPV1 拮抗剂。其中,化合物24S对辣椒素诱导的活化显示出立体特异性和优异的TRPV1拮抗作用。此外,它在大鼠神经性疼痛模型中表现出强烈的抗异常性疼痛。与其通过 TRPV1 的体外作用一致,化合物 24S 可阻断辣椒素诱导的小鼠体温过低。对 24S 与我们的 hTRPV1 同源模型进行对接分析,以确定其结合模式。
