Description

Bisindolylmaleimide I (GF109203X) is a highly selective and potent protein kinase C (PKC) inhibitor, exhibiting a Ki of 14 nM. This cell-permeable compound is widely used in both in vitro and in vivo research to investigate PKC signaling pathways in cancer, neuroscience, and cardiovascular studies.

Bioactivity

• Target IC50:

• In Vivo:
  GF109203X (10 μg/mouse, i.pl.) dose-dependently inhibits BK-induced mechanical allodynia in Wistar rats.
• In Vitro:
  Bisindolylmaleimide I, as an ATP-competitive PKC inhibitor, prevents platelet aggregation induced by stimuli that activate PKC, and has the potential as a tool for studying the involvement of PKC in signal transduction pathways. GF 109203X produces reversal activity on P-glycoprotein and MRP -mediated multidrug resistance. PKC inhibition by Bisindolylmaleimide I significantly reduces carbachol-stimulated ERK1/2 activation and the subsequent proliferation of SNU-407 colon cancer cells.
• Cell Research:
  Cell proliferation is monitored by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Cells are seeded in 96-well plates and allowed to grow overnight. The cells are serum-starved for 18–24 hours and then treated with 1 mM carbachol for 48 hours in 100 μL serum-free RPMI 1640. Inhibitors are added 30 min prior to carbachol treatment. Following the treatment, 10 μL of MTT solution (5 mg/ml) is applied to each well, and the plates were incubated for 3 h at 37 °C. After the medium is removed, the formazan crystals formed are solubilized in 100 μL DMSO. The absorbance at 570 nm is measured using a microplate reader and the background absorbance at 690 nm is subtracted. Each assay is performed in triplicate. (Only for Reference)
