fty720 phosphate

FTY720 (S)-Phosphate is the active stereoisomeric phosphate derivative of FTY720 that acts as a potent modulator of sphingosine-1-phosphate (S1P) receptors. FTY720 (S)-Phosphate binds to S1P receptor subtypes S1P1, S1P3, S1P4, and S1P5 with Ki values of 2.1, 5.9, 23, and 2.2 nM respectively, causing receptor internalization on lymphocytes， preventing S1P-mediated lymphocyte egress from lymphoid tissues. FTY720 (S)-Phosphate also enhances endothelial barrier integrity, stimulates transporters such as Abcb1 and Abcc1, and inhibits cytosolic phospholipase A2 activity, highlighting its multifunctional pharmacological properties, making it an compound of interest in the research of diseases including multiple sclerosis, autoimmune diseases and cancer.

Fingolimod hydrochloride (FTY720) , a novel immune modulator, is a sphingosine 1-phosphate (S1P) antagonist (IC50: 0.033 nM in K562 and NK cells).

Azido-FTY720 (azido-Fingolimod) is an analogue of FTY720 featuring an azido group suitable for click chemistry reactions. FTY720 is an orally available S1P analogue and S1P1R modulator capable of crossing the blood-brain barrier (BBB), reducing neuroinflammation, and is indicated for multiple sclerosis (MS).

FTY720 (S)-Phosphate, an S1P receptor 1 (S1PR1) agonist, is utilized in studying acute inflammatory diseases, including acute lung injury.

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.
