4LSC3318 Sphingosine (d18:1) CAS# 123-78-4

Catalog Number: 4LSC3318
CAS #: 123-78-4
Name: D-erythro-Sphingosine C-18 base, Sphingosine (d18:1)


Sphingosine (d18:1) is formed primarily from the breakdown of ceramide. Sphingosine inhibits protein kinase C and phosphatidic acid phosphohydrolase, whereas it activates phospholipase D and diacylglycerol (DAG) kinase. Phosphorylation of sphingosine by sphingosine kinases 1 and 2 (SPHK 1, SPHK 2) produces sphingosine-1-phosphate, a potent bioactive lipid that exhibits a broad spectrum of biological activities including cell proliferation, survival, migration, cytoskeletal organization, and morphogenesis.

Major activities:

  • Apoptosis induction
  • Mitogenic
  • Involved in cell proliferation
  • Invovlved in Gene expression
