Go 6983
Go 6983 (CAS 133053-19-7) is a selective inhibitor of protein kinase C isoforms PKCα, PKCβ, PKCγ, PKCδ, and PKCμ, with reported IC50 values of approximately 7 nM, 7 nM, 6 nM, 10 nM, and 20 mM, respectively. Protein kinase C (PKC) isoforms act as receptors for tumor-promoting phorbol ester, mediating various downstream cellular functions. In cancer cell models, Go 6983 suppresses PKCα and PKCδ activation induced by phorbol esters and reduces PKCη expression, inhibiting cell survival pathways. It is frequently employed in biomedical studies examining PKC-dependent signaling in cancer progression and epithelial-to-mesenchymal transition (EMT).

Kinase experiment [1]: | |
Binding assay |
Phosphorylation reactions were carried out in a total volume of 100 μL, containing buffer C (50 mM Tris-HC1, pH 7.5, 10 mM β-mercaptoethanol), 4 mM MgCl2, 10 μg PS, 100 nM TPA, 5 μL of a Sf158 cell extract as a source of recombinant PKCμ or of Sf9 cell extracts as a source of other recombinant PKC isoenzymes, 10 μg of syntide 2 as substrate, and 35 μM ATP containing 1 μCi [γ-32P]ATP. In some experiments PS and TPA were omitted or various inhibitors at concentrations indicated in the text were added. After incubation for 10 mins at 30 °C, the reaction was terminated by transferring 50 μL of the assay mixture onto a 20-mm square piece of phosphocellulose paper, which was washed 3 times in deionized water and twice in acetone. The radioactivity on each paper was determined by liquid scintillation counting. |
Cell experiment [2]: | |
Cell lines |
ARCcPE cells |
Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20 °C for several months. |
Reaction Conditions |
200 and 1000 nM; 48 hrs |
Applications |
In ARCaPE cells, Go 6983 at the dose of 200 nM significantly inhibited the up-regulation of PKCs(PKCα, PKCβ and PKCγ) stimulated by the PMA treatment. In addition, Go 6983 showed complete inhibition at the dose of 1000 nM. |
Animal experiment [3]: | |
Animal models |
Mice bearing B16BL6 tumors |
Dosage form |
22 μg/mouse, i.v. |
Applications |
In a mouse pulmonary B16BL6 tumor model, Go6983 at the dose of 22.0 μg/mouse significantly inhibited tumor metastasis by 51.2 %. |
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
