Herein, we disclose the discovery and optimization of 2-piperidin-4-yl-acetamide derivatives as MCH-R1 antagonists. Structural investigation of piperidin-4-yl-amide and piperidin-4-yl-ureas identified 2-piperidin-4-yl-acetamide-based MCH-R1 antagonists with outstanding in vivo efficacy but flawed with high affinity towards the hERG potassium channel. While existing hERG SAR information was employed to discover
在这里,我们公开了2-哌啶-4-基-乙酰胺衍生物作为MCH-R1拮抗剂的发现和优化。哌啶-4-基-酰胺和哌啶-4-基-尿素的结构研究确定了基于2-哌啶-4-基-乙酰胺的MCH-R1拮抗剂,具有出色的体内功效,但对hERG钾通道具有高亲和力。尽管利用现有的hERG SAR信息发现了hERG抑制作用最小的高效MCH-R1拮抗剂,但其他障碍阻碍了其后续的临床探索。
