Bisindolylmaleimide VIII acetate

Bisindolylmaleimide VIII acetate (Ro 31-7549 acetate) is a potent and selective protein kinase C (PKC) inhibitor with an IC50 of 158 nM for rat brain PKC. Bisindolylmaleimide VIII acetate has IC50s of 53, 195, 163, 213, and 175 nM for PKC-α, PKC-βI, PKC-βII, PKC-γ, PKC-ε, respectively. Bisindolylmaleimide VIII acetate facilitates Fas-mediated apoptosis and inhibits T cell-mediated autoimmune diseases.

How to use

In Vitro:

Bisindolylmaleimide VIII acetate (Ro 31-7549 acetate; 5 μM; 8, 12 hours) dramatically increases TRA-8-induced cell death in time-dependent and TRA-8 dose-dependent manners. Bisindolylmaleimide VIII acetate (5 μM; 6 hours) significantly decreases procaspase-8 at 4 h and completely disappeares at 6 h after the combined treatment with TRA-8.

In Vivo:

Bisindolylmaleimide VIII acetate (Ro 31-7549 acetate; 100 μg; IP; every other day for three doses) results in nearly complete tumor regression combined toTRA-8. The treatment with Bisindolylmaleimide VIII acetate alone does not induce significant tumor regression.
