Bisindolylmaleimide I (BIM I) is a highly selective, cell-permeable, and reversible protein kinase C (PKC) inhibitor (Ki = 14 nM) that is structurally similar to the poorly selective PKC inhibitor staurosporine.1 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.1 BIM I directly inhibits GSK3 in primary adipocyte lysates (IC50 = 360 nM) and in GSK3β immunoprecipitates derived from rat epididymal adipocytes (IC50 = 170 nM).2 This compound also competitively antagonizes the 5-HT3 receptor with a Ki value of 61 nM.3
