D-erythro-Sphingosine-1-phosphate-13C2,D2

A labelled putative lipid second messenger; found to inhibit cellular mobility of melanoma cells at very low concentrations with no toxic effects thereby making it a possible agent for prevention of tumor cell metastasis and inflammatory processes; mobilizes intracellular calcium stores; decreases cellular cAMP; activates phospholipase D; does not inhibitprotein kinase C.
