Transient receptor potential melastatin 8 (TRPM8), a temperature-sensitive ion channel responsible for detecting cold, is an attractive molecular target for the treatment of pain and other disorders. We have previously discovered a selective TRPM8 antagonist, KPR-2579, which inhibited bladder afferent hyperactivity induced by acetic acid instillation into the bladder. However, additional studies have
瞬态受体电位褪黑素 8 (TRPM8) 是一种负责检测寒冷的温度敏感离子通道,是治疗疼痛和其他疾病的有吸引力的分子靶标。我们之前已经发现了一种选择性 TRPM8 拮抗剂 KPR-2579,它可以抑制由醋酸注入膀胱引起的膀胱传入过度活跃。然而,其他研究揭示了 KPR-2579 的潜在副作用,例如反应性代谢物的形成、CYP3A4 诱导和抽搐。在本报告中,我们描述了 α-苯基甘氨酰胺衍生物的优化,以减轻这些不利影响的风险。最佳化合物13x 对 icilin 诱导的湿狗颤抖和寒冷诱导的大鼠频繁排尿表现出有效的抑制作用,对潜在的副作用具有广泛的安全范围。
