Merck, 376650-5MG, D-erythro-Sphingosine, N-Hexanoyl-

General description
Biologically active, cell-permeable, non-physiological ceramide analog. Induces a dramatic arrest in the G₀/G₁ phase of the cell cycle. Activates MAP kinase. Activates protein phosphatase 2A (PP2A) at 10 nM. Inhibits diacylglycerol accumulation and phospholipase D (PLD) activation in fibroblasts. Induces apoptosis in MOLT-4 leukemia cells.
Biologically active, cell-permeable, nonphysiological ceramide analog. Stimulates cytosolic serine/threonine protein phosphatase in T9 cells and induces phosphorylation on Thr-669 in A-431 cells by stimulation of ceramide-activated protein kinase. Induces a dramatic arrest in the Go/G₁ phase of the cell cycle. Activates MAP kinase. Activates protein phosphatase 2A (PP2A) at 10 nM. Inhibits diacylglycerol accumulation and phospholipase D activation in fibroblasts. Induces apoptosis in Molt-4 leukemia cells.
