A series of fused-pyrimidine derivatives have been discovered as potent and orally active GPR119 agonists. A combination of the fused-pyrimidine structure and 4-chloro-2,5-difluorophenyl group provided the 5,7-dihydrothieno[3,4-d]pyrimidine 6,6-dioxide derivative 14a as a highly potent GPR119 agonist. Further optimization of the amino group at the 4-position in the pyrimidine ring led to the identification
已经发现一系列稠合的嘧啶衍生物作为有效和口服活性的GPR119激动剂。稠合的嘧啶结构和4-氯-2,5-二氟苯基的组合提供了5,7-二氢噻吩并[3,4- d ]嘧啶6,6-二氧化物衍生物14a,作为高效的GPR119激动剂。嘧啶环中4位氨基的进一步优化导致鉴定出2- 1- [2-(4-氯-2,5-二氟苯基)-6,6-dioxido-5,7-作为高级类似物的二氢噻吩并[3,4- d ]嘧啶-4-基]哌啶-4-基}乙酰胺(16b)。发现化合物16b在小鼠中具有极强的激动活性,并在0.1 mg / kg po时具有改善的葡萄糖耐量。我们考虑化合物16b 及其类似物在探索GPR119激动剂作为治疗2型糖尿病的潜在治疗剂的实用性方面具有明显的实用性。
