Chemical Properties
White Crystalline Solid
Uses
A biologically active, cell permeable, but nonphysiologic ceramide analog. It inhibits cell proliferation and induces monocytic differentiation of HL-60 cells and induces apoptosis. It stimulates protein phosphatase 2A and activates MAP Kinase2
Biological Activity
A potent modulator of cell proliferation and differentiation. Activates protein phosphatase-1 (PP1) and -2A (PP2A), as well as ceramide-activated protein phosphatase (CAPP) in vitro .
Description
C2 ceramide is a cell-permeable analog of naturally occurring ceramides. It mediates many diverse biological activities, as do natural ceramides. These processes include differentiation of HL-60 cells, induction of apoptosis, activation of protein phosphatase 2A, and inhibition of the mitochondrial respiratory chain. C2 ceramide also enhances the expression of COX-2 in human dermal fibroblasts and stimulates the growth of bovine aortic smooth muscle cells. The ability of C2 ceramide to destabilize membranes may be responsible for its inhibition of platelet aggregation.
Definition
ChEBI: N-acetylsphingosine is a N-acylsphingosine that has an acetamido group at position 2.
Biochem/physiol Actions
Cell-permeable, biologically active ceramide. It induces differentiation and apoptosis in cells and has been shown to activate protein phosphatases.
storage
Desiccate at -20°C
