FTY720 Phosphate is a derivative of ISP-1 (myriocin) that is a fungal metabolite of the Chinese herb Iscaria sinclarii and a structural analog of sphingosine. FTY720 is a novel immune modulator that prolongs allograft transplant survival in numerous models by inhibiting lymphocyte emigration from lymphoid organs. It is phosphorylated by sphingosine kinase to the physiologically active phosphoric acid ester. FTY720 phosphate acts as a potent agonist at four of the sphingosine-1-phosphate (S1P) receptors (EDG-1, EDG-3, EDG-4, and EDG-5), with IC50 values of 0.2-6 nM.

Solubility in DMSO or in a solvent compatible for cell culture?

Asked by: JP_UCSF
Thank you for your question. FTY720 Phosphate is not very soluble in much at all, unfortunately. We found it to be insoluble in DMSO and soluble up to 0.5 mg/ml chloroform, but not in anything else we tried as a solvent. FTY720 phosphate is supplied as a crystalline solid. A stock solution may be made by dissolving the FTY720 phosphate in an organic solvent purged with an inert gas.
