sphinganine-1-phosphate

Sphinganine-1-phosphate (d17:0) is a sphingolipid analog of sphinganine-1-phosphate (d18:0) and sphingosine-1-phosphate (d18:1) that has a 17-carbon base. Sphinganine-1-phosphate (d17:0) levels are lower in surgical and cadaver trabecular meshwork samples isolated from patients with primary open angle glaucoma compared with control samples.

Sphinganine 1-phosphate (鞘氨醇-1-磷酸）是sphingolipid代谢途径中的一个中间产物，结构上和sphingosine相似。D-erythro-Dihydrosphingosine 1-phosphate在小鼠中通过激活S1P1受体对肾脏和肝脏具有保护作用。在智人（Homo sapiens）中作为S1P4的激动剂，并且可能激活GPR63（G蛋白偶联受体），主要用于研究Fabry病，Gaucher病，Krabbe疾病和脑白质营养不良（Leukodystrophy）。

D-erythro-Sphingosine (trans-4-Sphingenine) 是一种非常有效的p32激酶活化剂，EC50为 8 μM。它也是一种PP2A 激活剂，抑制蛋白激酶 C (PKC)。

Sphinganine (d20:0) is a natural isomer of dihydro-D-erythro-sphinganine (sphinganine (d18:0); that is a precursor of ceramide and sphingosine as well as a substrate for sphingosine kinases, which generate sphingosine-1-phosphate (d18:1) . In S. cerevisiae, the amount of sphinganine (d20:0) increases 10.8-fold in response to heat stress, indicating it is involved in heat stress adaptation. Sphinganine levels increase significantly in response to certain mycotoxins, including fumonisins as well as in some cancers. Sphinganine can block protein kinase C activation in some cases but not others.

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)
