Enantioselective synthesis of the phosphate esters of the immunosuppressive lipid FTY720
摘要:
The enantiomers of FTY720-phosphate (3) were synthesized via 2-methylene-4-(4-octylphenyl)butan-1-ol (7), 2,3-epoxy alcohol 8, and Delta(2)-oxazoline 10. These compounds have potential use in the treatment of autoimmune diseases and prevention of kidney transplant rejection. (c) 2005 Elsevier Ltd. All rights reserved.

The first enantioselective synthesis of chiral isostericphosphonateanalogues 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。
