GPR103拮抗剂表现出体内的厌食活性:模仿QRFP26的C端Arg-Phe基序的吡咯并[2,3- c ]吡啶的设计与开发。
摘要:
据报道,GPR103是一种G蛋白偶联受体,通过内源性神经肽配体QRFP26和QRFP43的激活而具有致癌作用。认识到QRFP26和QRFP43的中央给药可增加大鼠的高脂肪食物摄入量,因此我们决定研究GPR103的拮抗剂是否可以在控制喂养行为中发挥作用。在这里,我们介绍了作为GPR103小分子拮抗剂的吡咯并[2,3- c ]吡啶新系列的开发,这些拮抗剂具有GPR103亲和力,药物代谢和药代动力学以及适合药物开发的安全性参数。在测量食物摄入量的临床前肥胖模型中,吡咯并[2,3- c证明了吡啶吡啶GPR103拮抗剂。此外,使用NMR确定了内源性激动剂QRFP26 (20–26)的C端七肽的动态3D溶液结构。将合成的吡咯并[2,3- c ]吡啶拮抗剂与该实验结构进行了比较,该实验结构显示了可能的药效团特征重叠,为进一步设计GPR103拮抗剂提供了支持。
