General description

Highly purified preparation of bovine brain sphingosine containing >99% of the erythro isomer.

Highly purified preparation of bovine brain sphingosine containing >99% of the erythro isomer. A potent, cell-permeable, reversible, and selective inhibitor of protein kinase C (PKC; IC₅₀ = 2.8 µM) and insulin receptor tyrosine kinase. PKC inhibition is competitive with respect to diacylglycerol, phorbol dibutyrate, and Ca²⁺. Does not affect the activity of myosin light chain kinase and protein kinase A. Induces apoptosis in human leukemia HL-60 cells. Note: This product is not to be used for animal treatment, in vivo research or in any other contact procedure with livestock.
