Biological Activity

FTY720 (Fingolimod) Hydrochloride is a potent immunomodulatory agent and sphingosine-1-phosphate receptor agonist upon phosphorylation to FTY720-phosphate. It promotes lymphocyte sequestration within lymph nodes, blocking auto-reactive immune cell trafficking. Additionally, FTY720 activates the tumor suppressor protein phosphatase 2A (PP2A), downregulating downstream oncogenic signaling pathways and suppressing cell proliferation in leukemia and hepatocellular carcinoma models.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
