Sphingosylphosphorylcholine	1670-26-4	99.50%
Sphingosylphosphorylcholine is a bioactive lipid and a major component of plasma high-density lipoprotein that binds to OGR1 with a K_d of 33.3 nM. Sphingosylphosphorylcholine triggers delayed phosphorylation of Smad2, upregulates α-SMA expression, and activates TRPM3. Sphingosylphosphorylcholine reduces Apoptosis and upregulates the expression of uPA and its receptor uPA-R. Sphingosylphosphorylcholine exerts anti-apoptotic, anti-cardiac hypertrophy and pro-wound healing effects. Sphingosylphosphorylcholine induces scratching behavior in mice. Sphingosylphosphorylcholine is used in studies related to atopic dermatitis, promyelocytic leukemia, heart failure, myocardial ischemia/reperfusion injury, ovarian cancer, breast cancer, pancreatic cancer, and skin wound healing disorders in genetically impaired healing diabetes.

N,N-Dimethylsphingosine	119567-63-4	99.93%
N,N-Dimethylsphingosine is a sphingosine kinase inhibitor. N,N-Dimethylsphingosine binds competitively to sphingosine kinase and blocks the conversion of sphingosine to sphingosine-1-phosphate. N,N-Dimethylsphingosine inhibits sphingosine-1-phosphate release and aggregation of platelets, and also exerts pro-apoptotic effects by resetting ceramide/sphingosine-1-phosphate homeostasis. N,N-Dimethylsphingosine can be used in cancer-related research.

Fumonisin B2 is a selective ceramide synthase inhibitor and carcinogenic mycotoxin with toxicity comparable to that of Fumonisin B1 (HY-N6719). Fumonisin B2 inhibits de novo sphingolipid biosynthesis by blocking the amide bond formation between fatty acids and dihydrosphingosine, which leads to a massive intracellular accumulation of free dihydrosphingosine, altered sphingosine levels, subsequent inhibition of cell proliferation, and induction of cell death. Fumonisin B2 is used to investigate the pathogenesis of diseases associated with Fusarium verticillioides contamination, including equine leukoencephalomalacia, porcine pulmonary edema syndrome, human esophageal cancer, and rat hepatocellular carcinoma.
