Pharmacological modulation of the transient receptor potential melastatin type 8 (TRPM8) is currently under investigation as a new approach for the treatment of pain and other diseases. In this study, a series of N-substituted tryptamines was prepared to explore the structural requirements determining TRPM8 modulation. Using a fluorescence-based screening assay, we identified two compounds acting as
目前正在研究8型瞬时受体电位褪黑素(TRPM8)的药理学调节,作为治疗疼痛和其他疾病的新方法。在这项研究中,准备了一系列的N-取代的色胺,以探索确定TRPM8调节的结构要求。使用基于荧光的筛选分析,我们确定了两种化合物作为激活剂(2-(1 H-吲哚-3-基)-N-(4-苯氧基苄基)乙胺,21)或抑制剂(N,N-二苄基-2-(1 H-吲哚-3-基)乙胺,12)的钙流入HEK293细胞。在膜片钳录音中,化合物21与薄荷醇相比,显示出显着更高的效力(EC 50 = 40±4μM)和相似的功效;相反,化合物12对薄荷醇诱导的TRPM8电流产生浓度依赖性抑制(IC 50 = 367±24 nM)。使用单个大鼠TRPM8亚基的同源性模型进行的分子建模研究确定了位于VSD和TRP盒之间的推定结合位点,揭示了激动剂和拮抗剂的结合方式不同。
