fty720p

FTY720 (S)-Phosphate is an S1P receptor 1 (S1PR1) agonist. It is used in the research of acute inflammatory diseases such as acute lung injury.

FTY720 (S)-Phosphate，作为S1P受体1 (S1PR1) 激动剂，可用于研究急性肺损伤等急性炎症。

FTY720, an immune modulator, down-regulates sphingosine-1-phosphate (S1P) receptors, enhances the activity of sphingosine transporter Abcb1 and leukotriene C4 transporter Abcc1, and inhibits cytosolic phospholipase A2 activity. Its efficacy relies on in vivo phosphorylation by sphingosine kinases, resulting in FTY720-phosphate which also down-regulates S1P receptors. NBD-FTY720, a fluorescently-labeled analog of FTY720, retains the hydroxy methyl side chain targeted for phosphorylation, suggesting potential phosphorylation in vivo.
