Product Description
Potent inhibitor of protein phosphatases 1 (PP1) and 2A (PP2A) in numerous cell types. Does not affect activity of acid phosphatase, alkaline phosphatase and tyrosine phosphatase. Non-phorbol type tumor promoter. Induces apoptosis in human breast carcinoma cells (MB-231 and MCF-7) and in myeloid cells, but inhibits glucocorticoid-induced apoptosis in T cell hybridomas. Tumor promoter. Has shown contractile effect on smooth muscle and heart muscle. Significantly increases cyclin B1 expression in adult neurons.
