Novel 4-amino-2-phenylpyrimidine derivatives were synthesized and evaluated as GPR119 agonists. Optimization of the substituents on the phenyl ring at the 2-position and the amino group at the 4-position led to the identification of 3,4-dihalogenated and 2,4,5-trihalogenated phenyl derivatives showing potent GPR119 agonistic activity. The advanced analog (2R)-3-[2-(4-chloro-2,5-difluorophenyl)-6-
合成了新型的4-氨基-2-苯基嘧啶衍生物,并将其评估为GPR119激动剂。优化2-位苯环上的取代基和4-位氨基上的取代基,可以鉴定出显示出强效GPR119激动活性的3,4-二卤代和2,4,5-三卤代苯基衍生物。发现高级类似物(2 R)-3-[2-(4-氯-2,5-二氟苯基)-6-乙基嘧啶-4-基]氨基}丙烷-1,2-二醇(24g)可以改善在小鼠中口服1 mg / kg的葡萄糖耐量,并在小鼠和猴子中表现出出色的药代动力学特征。在单日治疗一周后,化合物24g在糖尿病kk / Ay小鼠中也显示出优异的抗糖尿病作用。这些结果表明,新型GPR119激动剂24g 不仅可以通过增强葡萄糖依赖性胰岛素的分泌来改善葡萄糖耐受性,还可以通过保留胰腺β细胞功能来改善葡萄糖耐受性。
