Bisindolylmaleimide I (BIM I) is a highly selective, cell-permeable, and reversible PKC inhibitor (K = 14 nM) that is structurally similar to the poorly selective PKC inhibitor staurosporine . It acts as a competitive inhibitor for the ATP binding site of PKC and shows high selectivity for PKCα, β1, β2, γ, δ, and ε isozymes. BIM I directly inhibits glycogen synthase kinase 3 (GSK3) in primary adipocyte lysates (IC = 360 nM) and in GSK3β immunoprecipitates derived from rat epididymal adipocytes (IC = 170 nM). It also competitively antagonizes the serotonin (5-HT) receptor subtype 5-HT with a K value of 61 nM.
Bisindolylmaleimide I (hydrochloride) is a cell-permeable and reversible PKC inhibitor (IC50 of 20 nM, 17 nM, 16 nM, and 20 nM for PKCα, PKCβI, PKCβII, and PKCγ. Bisindolylmaleimide I (hydrochloride) is also a GSK-3 inhibitor.
