Bisindolylmaleimide VIII acetate (Ro 31-7549 acetate) 是一种有效的选择性蛋白激酶 C (PKC) 抑制剂，对大鼠脑 PKC 的IC50为 158 nM。Bisindolylmaleimide VIII acetate 对 PKC-α，PKC-βI，PKC-βII，PKC-γ，PKC-ε 的 IC50分别为 53、195、163、213 和 175 nM。Bisindolylmaleimide VIII acetate 促进 Fas 介导的细胞凋亡 (apoptosis)，并抑制 T 细胞介导的自身免疫性疾病。
| 生物活性 | Bisindolylmaleimide VIII acetate (Ro 31-7549 acetate) is a potent and selectiveprotein kinase C (PKC)inhibitor with anIC50of 158 nM for rat brainPKC. 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[1]. Bisindolylmaleimide VIII acetate facilitates Fas-mediatedapoptosisand inhibits T cell-mediated autoimmune diseases[2]. |

体外研究
(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[2].
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[2].

体内研究
(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[2].
