We describe the discovery and optimization of a novel series of furo[3,2-d]pyrimidines as G protein-coupled receptor 119 agonists. Agonistic activity of 4 (EC50 = 129 nM) was improved by replacing the intramolecular hydrogen bond between the fluorine atom and the aniline hydrogen in the head moiety with a covalent C-C bond to enhance conformational restriction, which consequently gave a lead compound
我们描述了作为G蛋白偶联受体119激动剂的呋喃[3,2- d ]嘧啶系列的发现和优化。的激动活性4(EC 50 = 129纳米)通过更换氟原子和在用共价CC键的头部部分中的苯胺氢之间的分子内氢键,以提高构象的限制,因此这给了铅化合物改善12(EC 50 = 53 nM)。通过进一步优化12而确定的优化化合物26表现出强大的活性(EC 50 在C57BL / 6N小鼠的口服葡萄糖耐量试验中,以10 mg / kg的剂量在肝脏微粒体中的清除率提高了(= 42 nM),并且曲线下的血糖面积降低了33%。
