The discovery and optimization of piperidin-4-yl-urea derivatives as MCH-R1 antagonists is herein described. Previous work around the piperidin-4-yl-amides led to the discovery of potent MCH-R1 antagonists. However, high affinity towards the hERG potassium channel proved to be an issue. Different strategies to increase hERG selectivity were implemented and resulted in the identification of piperidin-4-yl-urea
本文描述了作为MCH-R1拮抗剂的哌啶-4-基-脲衍生物的发现和优化。以前关于哌啶丁-4-基-酰胺的研究导致发现了有效的MCH-R1拮抗剂。然而,对hERG钾通道的高亲和力被证明是一个问题。实施了提高hERG选择性的不同策略,并导致鉴定出哌啶-4-基-脲化合物为有效的MCH-R1拮抗剂,且对hERG的抑制作用最小。
