Cat.No. 4640 - N,N-Dimethylsphingosine | C20H41NO2 | CAS No. 119567-63-4
Description: Sphingosine kinase inhibitor
Chemical Name: (2S,3R,4E)-2-(Dimethylamino)-4-octadecene-1,3-diol
Purity: ≥98% (HPLC)
Literature (2)

Biological Activity

Competitive sphingosine kinase (SphK) inhibitor. Exhibits inhibitory activity in platelets and in cytosolic extracts from U937, Swiss 3T3 and PC12 cells. Selectively inhibits sphingosine phosphorylation; does not inhibit N-acylation, and displays no inhibitory effect on protein kinase C at concentrations that inhibit SphK. Increases the release of IL-1β and MCP-1 in cultured astrocytes; thought to mediate mechanical allodynia via this mechanism.
