d-erythro/l-threo lysosphingomyelin

Lysosphingomyelin is an endogenous bioactive sphingolipid and a constituent of lipoproteins.1,2It is produced by the removal of the acyl group from sphingomyelin by a deacylase and acts as a precursor in the biosynthesis of sphingosine-1-phosphate . D-erythroLysosphingomyelin is an agonist of the S1P receptors S1P1, S1P2, and S1P3(EC50s = 167.7, 368.1, and 482.6 nM, respectively, for the human receptors).3It is also an agonist of the orphan receptor ovarian cancer G protein-coupled receptor 1 (ORG1) that induces calcium accumulation in cells overexpressing OGR1 (EC50= ~35 nM).4Levels of D-erythrolysosphingomyelin are increased in skin isolated from patients with atopic dermatitis, as well as postmortem brain from patients with Niemann-Pick disease type A, but not type B.2,5L-threolysosphingomyelin is also an S1P1-3agonist (EC50s = 19.3, 131.8, and 313.3 nM, respectively).3This product is a mixture of D-erythroand L-threolysosphingomyelin.
