DL-threo dihydrosphingosine is a cell-permeable inhibitor of the extracellular signal-regulated kinase (ERK) signalling cassette in mammalian cells. DL-threo dihydrosphingosine is effective against both growth factor- and G-protein-dependent activation of
3-Keto Sphinganine (d12:0) is a short-chain analog of 3-keto sphinganine (d18:0), which typically possesses a C18 chain length. The latter is a lyso-sphingolipid synthesized through the condensation of L-serine and palmitoyl-CoA mediated by the enzyme serine palmitoyl transferase (SPT). A deficiency in Vitamin K deactivates SPT, leading to a reduced synthesis of 3-keto sphinganine among other sphingolipids. [Matreya, LLC. Catalog No. 1893]
A6770 is an inhibitor of sphingosine-1-phosphate (S1P) lyase.1It induces accumulation of [3H]sphinganine-1-phosphate ([3H]dhS1P), an S1P lyase substrate, in IT-79MTNC3 cells that endogenously express high levels of S1P lyase (EC50= <0.01 μM), an effect that is reduced in the presence of vitamin B6(EC50= <100 μM). 1.Ohtoyo, M., Tamura, M., Machinaga, N., et al.Scintillation proximity assay to detect the changes in cellular dihydrosphingosine 1-phosphate levelsLipids51(10)1207-1216(2016)
Sphingosine (d18:1), an amino alcohol, is chiefly recognized for its 18-carbon unsaturated hydrocarbon chain. Nevertheless, in mammalian tissues, both sphingosine and its variant, dihydrosphingosine, feature hydrocarbon chains ranging from 12 to 26 carbons. Sphingosine (d15:1) represents a naturally rare variant, serving as an internal standard for chromatographic or spectrometric analyses of sphingoid compounds.
