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
描述了 FTY720 的手性等排膦酸酯类似物的第一个对映选择性合成。其中一个类似物 FTY720-( E )-乙烯基膦酸酯 ( S )- 5,而不是它的R对映异构体,在肠上皮细胞中引起有效的抗凋亡作用,表明它通过受体的对映选择性激活发挥作用。( S ) -5未能激活 1-磷酸鞘氨醇 1 型 (S1P 1 ) 受体。
