Biological Activity

Selective inhibitor of protein phosphatase (PP)1 (IC50 values are 1.6 and 62 nM for PP1 and PP2 respectively). Reduces PDGF-induced vascular smooth muscle cell and mesangial cell proliferation without affecting fibronectin secretion and cellular kinase activation in vivo. Immunosuppressive agent; inhibits proliferation and induces apoptosis in activated T cells.
