Biological Activity for Ro 31-8220 mesylate

Ro 31-8220 mesylate is a protein kinase C inhibitor, with activity at other protein kinases (IC50 values are 33, 3, 8, 15 and 38 nM for PKCα, MAPKAP-K1b, MSK1, GSK3β and S6K1 respectively). Activates JNK and glycogen synthase, and inhibits MAPK and ERK2, in rat adipocytes and L6 myotubes. Also inhibits voltage-dependent Na+ channels in the micromolar range. Induces protein-protein interaction between mutant SMAD4R361H and SMAD3, leading to reactivation of dormant SMAD4R361H-mediated transcriptional activity and restoration of TGF-β-induced tumor suppression activity in SMAD4 mutant cancer cells.
