dose-dependently blocks icilin-triggered shaking behaviors in mice. Upon local administration, compound 14 dose dependently inhibits cold allodynia evoked by the chemotherapy oxaliplatin in a murine model of peripheral neuropathy at microgram doses. Our findings suggest that 14 and other biphenyl amide analogues within our series can find utility as potent antagonist chemical probes derived from (-)-menthol
报道的基于薄荷醇的瞬时受体潜在阳离子通道亚家族M成员8通道(TRPM8)拮抗剂的结构活性关系研究,在计算模拟和基于结构的设计的指导下,发现了一系列新的TRPM8拮抗剂,其选择性> 10倍。相关的TRP亚型。Spiro [4.5] decan-8-yl类似物14抑制伊西林诱发的Ca2 +进入稳定表达人TRPM8(hTRPM8)的HEK-293细胞,IC50为2.4±1.0 nM,而在全细胞膜片钳记录中,该类似物抑制薄荷醇诱发的电流,hTRPM8 IC50为64±2 nM。在我们的hTRPM8同源模型中,化合物14的分子动力学(MD)模拟表明,该拮抗剂在正构位点内形成广泛的疏水性接触。在湿狗摇(WDS)分析中,化合物14剂量依赖性地阻断了西西林触发的小鼠摇动行为。局部给药后,化合物14剂量依赖性地抑制微克剂量的周围神经病的鼠模型中由化学疗法奥沙利铂引起的感性异常性疼痛。我们的发现表明,我们系列
