Dihydro-D-erythro-Sphingosine is a biosynthetic precursor of sphingosine that inhibits PKC (protein kinase C) in Chinese hamster ovary cells (IC50 = 2.8 μM). Dihydro-D-erythro-Sphingosine also directly inhibits PLA2 (phospholipase A2) and PC-PLD (phospholipase D). Dihydro-D-erythro-Sphingosine is a substrate of SphK.
