Description:
IC50 Value: 5, 24, 14, 27, and 24 nM (PKC α, PKC βI, PKC βII, PKC γ, and PKC) [1]
Ro 31-8220, a staurosporine (sc-3510) analog, is a cell-permeable inhibitor of PKC (protein kinase C) isoforms PKC α, PKC βI, PKC βII, PKC γ, and PKC ε (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-3β, MSK1, Pim-3, Polycystin-1, PRK2, Rsk-1 and Rsk-2 and an activator of JNK1.
Ro 31-8220 antagonized (IC50, 1.0 microM) the effect of the activator of protein kinase C,12-O-tetradecanoylphorbol 13-acetate (TPA), on histamine-stimulated aminopyrine accumulation. Ro 31-8220 (0.1-2.14 microM) inhibited the aminopyrine response to 0.1 mM carbachol (IC50, 0.78 microM; 49% inhibition at 2.14 microM Ro 31-8220) and shifted
