| | GF109203X Usage And Synthesis |
| Description | GF-109203X (133052-90-1) is a potent and selective protein kinase C inhibitor (IC50 = 10 nM; cAMP-dependent protein kinase IC50 = 2 μM and phosphorylase kinase IC50 = 0.7 μM). Inactive against the tyrosine kinases EGFR, PGDFR and Insulin receptor. Potent inhibitor of GSK-3β in cell lysates (IC50 = 360nM) and GSK-3β immunoprecipitates (IC50 = 170nM) derived from rat epididymal adipocytes.2 Cell permeable. | | Uses | Bisindolylmaleimide is used as a highly selective inhibitor of all PKC isoforms and slight inhibitor of GSK-3, used to selectively probe for PKC-mediated pathways for transduction of hormone, cytokine, and growth factor signals, very potent and selective inhibitor of protein kinase C. | | Biological Activity | Very potent and selective inhibitor of protein kinase C, selective for the α and β 1 isoforms (IC 50 values are 0.0084, 0.0180, 0.210, 0.132, and 5.8 μ M for α , β 1, δ , ε , and ζ isoforms respectively). Selective over MLCK, PKG and PKA (IC 50 values are 0.6, 4.6, and 33 μ M respectively). Potent antagonist at the 5-HT 3 receptor (K i = 29.5 nM). Anti-inflammatory in vivo . Also available as part of the Mixed Kinase Inhibitor Tocriset™ . | | Biochem/physiol Actions | A potent and selective competitive inhibitor of protein kinase C (PKC) and of glycogen synthase kinase-3 (GSK-3). Inhibits parathyroid hormone-induced Ca2+ resorption from isolated bone tissue, Staurosporine, another protein kinase inhibitor, actually enhanced Ca2+ resorption elicited by a number of agents, but GF109203X counteracted that enhancement. | | storage | Store at RT | | References | 1) Toullec, et al.
