The first enantioselective synthesis of chiral isosteric phosphonate analogues of FTY720 is described. One of these analogues, FTY720-(E)-vinylphosphonate (S)-5, but not its R enantiomer, elicited a potent antiapoptotic effect in intestinal epithelial cells, suggesting that it exerts its action via the enantioselective activation of a receptor. (S)-5 failed to activate the sphingosine 1-phosphate type 1 (S1P(1)) receptor.
描述了FTY720手性等排膦酸酯类似物的首次对映选择性合成。这些类似物之一,FTY720-(E)-乙烯基膦酸酯(S)-5,而非其R对映体,在肠上皮细胞中引发了强大的抗凋亡作用,表明它通过对受体的对映选择性激活发挥作用。(S)-5未能激活1型鞘氨醇-1-磷酸(S1P(1))受体。
