Bisindolylmaleimide VIII is a selective PKC (protein kinase C) inhibitor, with observed binding activity to dystrophia myotonica protein kinase (DMPK). Bisindolylmaleimide VIII is suggested as being slightly more specific for PKC alpha over PKC beta, PKC gamma, and PKC epsilon isozymes (IC50 = 53, 195, 213, and 275 respectively). The compound may act to improve DR5-mediated apoptosis through the MKK4/JNK/p38 kinase. When bisindolylmaleimide VIII is combined with TRA-8 it can activate c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase. Bisindolylmaleimide VIII enhance Fas-mediated apoptosis in both human astrocytoma 1321N1 cells and in Molt-4T cells.
