QUICK LINKS

Ro 31-8220, a staurosporine (sc-3510) analog, is a cell-permeable inhibitor of PKC (protein kinase C) isoforms PKC alpha, PKC betaI, PKC betaII, PKC gamma, and PKC epsilon (IC50 = 5, 24, 14, 27, and 24 nM, respectively). Ro 31-8220 has also been shown to induce apoptosis in various cell lines, independent of its PKC activity, and to inhibit GSK 3 (IC50 = 6.8nM). Ro 31-8220 is an inhibitor of Cdk2, cyclin A, GSK-3beta, MSK1, Pim-3, Polycystin-1, PRK2, Rsk-1 and Rsk-2 and an activator of JNK1.
