Primary TargetPKC
Cell permeable: yes
General description
A highly selective cell-permeable protein kinase C (PKC) inhibitor (IC50 = 10 nM) that is structurally similar to staurosporine. Acts as a competitive inhibitor for the ATP-binding site of PKC. Shows high selectivity for PKCα, βI, βII, γ, δ, and ε isozymes. May inhibit protein kinase A at a much higher concentration (IC50 = 2 µM). Also inhibits telomerase activity in quercetin, H-89, or herbimycin A treated NPC-076 cells.
A highly selective, cell-permeable, and reversible protein kinase C (PKC) inhibitor (IC50 = 10 nM) that is structurally similar to staurosporine. Acts as a competitive inhibitor for the ATP-binding site of PKC. Shows high selectivity for PKCα-, βI-, βII-, γ-, δ-, and ε- isozymes. Potently inhibits GSK-3 in primary adipocyte lysates (IC50 = 360 nM) and in GSK-3β immunoprecipitates (IC50 = 170 nM). May inhibit protein kinase A at a much higher concentration (IC50 = 2 µM). A 1 mg/ml solution of Bisindolylmaleimide I (Cat. No. 203293) in anhydrous DMSO is also available.
