Application

N,N-Dimethylsphingosine has been used as an internal standard in liquid chromatography with tandem mass spectrometry (LC-MS-MS) for psychosine quantification in fibroblasts from twitcher (TWI) and wild type mice. It has also been used as an inhibitor of sphingosine kinase (SphK) to investigate the role of SphK in enhancing lipopolysaccharide (LPS)-mediated chemokine expression.

Biochem/physiol Actions

N,N-Dimethylsphingosine (DMS) is an endogenous metabolite of sphingosine produced in various tissues and tumor cell lines. N,N-Dimethylsphingosine is a potent inhbitor of sphingosine kinase. DMS levels are elevated in the spinal cord, and contributes to allodynia, in a transected-nerve model of neuropathic pain.

We showed previously that a new Pt complex containing an O,O'-chelated acetylacetonate ligand (acac) and a dimethylsulphide in the Pt coordination sphere, [Pt(O,O'-acac)(gamma-acac)(DMS)], induces apoptosis in HeLa cells. The objective of this study was to investigate the hypothesis that [Pt(O,O'-acac)(gamma-acac)(DMS)]

Sphingosine-1-phosphate (S1P) is a biologically active sphingolipid metabolite that exerts important effects on numerous cellular events via cell surface receptors, S1P(1-5). S1P influences differentiation, proliferation, and migration during vascular development. However, the effects of S1P signaling on early cardiac development

Sphingosine 1-phosphate receptors (S1PR) are G protein-coupled and compose a family with five subtypes, S1P1R-S1P5R. The drug Gilenya® (Novartis, Basel, Switzerland) (Fingolimod; FTY720) targets S1PRs and was the first oral therapy for patients with relapsing-remitting multiple sclerosis (MS). The phosphorylated

Neutrophils display three major functions: (i) oxidative burst, (ii) phagokinetic activity, and (iii) trans-endothelial migration. Sphingosine (SPN) is known to inhibit oxidative burst in human neutrophils via inhibition of protein kinase C (PKC). SPN is metabolically converted into N,N-dimethylsphingosine (DMS)

Sphingosine (SPN) has been claimed to be a negative modulator of transmembrane signaling through protein kinase C (PK-C) or some yet unidentified mechanism [for review see Y. A. Hannun and R. M. Bell, Science (Washington DC), 243: 500-507, 1989]. N,N-Dimethylsphingosine
