hydroxy group was replaced by fluorine, or the bridging oxygen in the monophosphate was replaced by an alpha-monofluoromethylene (-CHF-) moiety. The sn-1 or sn-2 monofluorinated LPA analogues were enantiospecifically prepared from chiral protected glycerol synthons, and the alpha-monofluoromethylene-substituted LPA analogues were prepared from a racemic epoxide with use of a hydrolytic kinetic resolution
溶血磷脂酸(LPA,1-或2-酰基-sn-甘油3-磷酸)显示出令人着迷的细胞生物学特性,该生物学特性是通过与G蛋白偶联的七个跨膜受体以及核激素受体PPARγ的相互作用而介导的。LPA的氟化类似物的合成和生物学活性仍然相对未知。为了确定受体选择性LPA类似物并详细记录氟化LPA等位基因的构效关系,我们描述了一系列单氟化LPA类似物,其中sn-1或sn-2羟基被取代氟或单磷酸中的桥连氧被α-单氟亚甲基(-CHF-)部分取代。从手性保护的甘油合成子对映体特异性制备了sn-1或sn-2单氟LPA类似物,使用水解动力学拆分方法,由外消旋环氧化物制备α-单氟亚甲基取代的LPA类似物。sn-2和sn-1氟LPA类似物无法进行酰基迁移,分别以sn-1-O-酰基或sn-2-O-酰基形式有效地“冻结”它们。α-单氟亚甲基LPA类似物是独特的新型不可水解配体,具有令人惊讶的对映体特异性和受体特异性生物学读数,其
