Discovery and biological evaluation of novel 4-amino-2-phenylpyrimidine derivatives as potent and orally active GPR119 agonists.

Abstract:

: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-ethylpyrimidin-4-yl]amino}propane-1,2-diol (24g) was found to improve glucose tolerance at 1mg/kg po in mice and to show excellent pharmacokinetic profiles in mice and monkeys. Compound 24g also showed an excellent antidiabetic effect in diabetic kk/Ay mice after one week of single daily treatment. These results demonstrate that novel GPR119 agonist 24g improves glucose tolerance not only by enhancing glucose-dependent insulin secretion but also by preserving pancreatic β-cell function.
