Sphinganine (d18:0) is a precursor of ceramide and sphingosine as well as a substrate of sphingosine kinases, which generate sphinganine-1-phosphate. Sphinganine levels increase significantly in response to certain mycotoxins, including fumonisins, as well as in some cancers. Sphinganine can block protein kinase C...

D-erythro Lysosphingomyelin is a bioactive sphingolipid. It is an agonist of sphingosine-1-phosphate receptor 1 (S1P1), S1P2, and S1P3 (EC50s = 167.7, 368.1, and 482.6 nM, respectively, for the human receptors). D-erythro Lysosphingomyelin is also an agonist of the orphan receptor ovarian cancer G protein-coupled...

Sphingosine is an amino alcohol most commonly characterized by an 18-carbon unsaturated hydrocarbon chain (Sphingosine (d18:1), Cay-10007907). However, the hydrocarbon chain length of sphingosine, and the related dihydrosphingosine, can vary from 12-26 carbons in mammalian tissues. Sphingosine (d15:1) is a...

Ionomycin is a calcium ionophore originally isolated from S. conglobatus. It induces intracellular calcium mobilization in X. laevis oocytes when used at a concentration of 5 µM. Ionomycin (5 µM) induces the formation of neutrophil extracellular traps (NETs) in isolated human neutrophils. Ionomycin in combination...

Epoxyeicosatrienoic acids (EETs), lipid mediators synthesized from arachidonic acid by cytochrome P-450 epoxygenases, are converted by soluble epoxide hydrolase (sEH) to the corresponding dihydroxyeicosatrienoic acids (DHETs). N,N' Dicyclohexylurea (DCU) is a selective sEH inhibitor with IC50 values of 160 and 90 nM...
