Go6976 (also known as PD-40697) is a novel, potent and selective inhibitor of PKC (Protein Kinase C)with potential antitumor activity. It inhibits PKC, PKCα, and PKCβ1 with IC50s of 7.9 nM, 2.3 nM, and 6.2 nM, respectively. In T cell lines ACH-2 and U1 infected with HIV-1, Go 6976 treatment effectively blocked viral transcription induced by Bryostain 1 or tumor necrosis factor α which lead to the inhibition of intracellular viral protein synthesis and viral shedding and also blocked IL-6 mediated posttranscriptional inducetion of viral protein.

Go6976 is a highly effective PKC inhibitor in vitro (IC50 = 20 nM). Its structural similarity to staurosporine makes it the most potent PKC inhibitor[1]. Interestingly, Go6976 is also found to abrogate S and G2 arrest. Dose-response studies show that 30 nM Go6976 is sufficient to abrogate S-phase arrest in 6 hours and complete abrogation of G2 arrest followed by lethal mitosis in 24 hours. Incubation of cells with 100 nM Go6976 is sufficient to completely abrogate S and G2 arrest at 6 and 24 hours, respectively, and is only slightly less potent than in bovine serum. At the concentrations used, incubation of cells with UCN-01 or Go6976 alone does not reduce viability in comparison to control. Incubation of cells with 5 ng/mL SN38 leads to

Solubility in Formulation 1: ≥ 3.25 mg/mL (8.59 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 32.5 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. Solubility in Formulation 2: 1.39 mg/mL (3.67 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 13.9 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
