Phosphonate analogues of phosphatidic acid (PA) were synthesized in which the bridging oxygen was replaced by an alpha-monofluoromethylene (-CHF-) or alpha-difluoromethylene (-CF(2)-) moiety using hydrolytic kinetic resolution (HKR) of a racemic epoxide as the key step. Since PA activates signaling in the mTOR (mammalian target of rapamycin) pathway, these metabolically stabilized PA analogues were evaluated
合成了磷脂酸(PA)的膦酸酯类似物,其中使用消旋体的水解动力学拆分(HKR)将桥联氧替换为α-单氟亚甲基(-CHF-)或α-二氟亚甲基(-CF(2)-)部分环氧是关键步骤。由于PA激活了mTOR(雷帕霉素的哺乳动物靶标)途径中的信号传导,因此在静止的HEK 293细胞中评估了这些代谢稳定的PA类似物。这些类似物中的大多数在激活S6激酶(mTOR信号的下游靶标)方面超过了PA。对于单-和二氟亚甲基膦酸酯,非天然(2R)类似物的活性均比天然(2S)对映异构体小。
