D-ERYTHRO-SPHINGOSINE Structural

What is D-ERYTHRO-SPHINGOSINE?

Description

Sphingosine (123-78-4) is an inhibitor of protein kinase C (IC50 = 1-3 μM).1 It is abundant in cell membranes and is an important mediator in various biochemical pathways.2-4

Chemical properties

White Crystalline Solid

The Uses of D-ERYTHRO-SPHINGOSINE

D-erythro-Sphingosine is used to inhibits protein kinase C and calmodulin-dependent enzymes, induces apoptosis. And also used to constituent of cell membranes.

The Uses of D-ERYTHRO-SPHINGOSINE

Selective inhibitor of protein kinase C activity and phorbol dibutyrate binding in vitro in human platelets; does not inhibit protein kinase A or myosin light chain kinase; inhibits calmodulin-dependent enzymes; natural isomer of sphingosine

The Uses of D-ERYTHRO-SPHINGOSINE

Sphingosine (d18:1) has been used:

  • for sphingosine inhalations studies in mice to evaluate its therapeutic potential in respiratory epithelial cells
  • to investigate its effect on Pseudomonas aeruginosa strains
  • as a standard in liquid chromatography tandem mass spectrophotometry for the quantification of epidermal ceramides

What are the applications of Application

D-erythro-Sphingosine is a potent, highly selective PKC inhibitor

Definition

cerebroside: Any one of a class ofglycolipids in which a single sugarunit is bound to a sphingolipid. The most commoncerebrosides are galactocerebrosides,containing the sugar group galactose;they are found in the plasma membranesof neural tissue and are abundantin the myelin sheaths ofneurones.

General Description

Sphingosine (d18:1) is a spingoid base present in plant and animals. It has 2-amino-1,3-diol functionality and its extraction from animal tissue is laborious. Sphingosine (d18:1) synthesis is performed by chirospecific method using D-galactose.

Biological Activity

Inhibitor of protein kinase C and calmodulin-dependent enzymes, but may stimulate mast cells by activation of protein kinase C.

Biochem/physiol Actions

A constituent of cell membranes. Precursor of ceramide. Selective inhibitor of protein kinase C, but does not inhibit protein kinase?A or myosin light chain kinase. Inhibitor of calmodulin-dependent enzymes.

Purification Methods

D-Sphingosine is purified by recrystallisation from EtOAc, Et2O or pet ether (60-80o). It is insoluble in H2O but is soluble in Me2CO, EtOH and MeOH. It has IR bands at 1590 and 875 cm-1, and is characterised as the tribenzoate m 122-123o (from 95% EtOH). [Tipton Biochemical Preparations 9 127 1962.]
