Biological Activity

Description Go6976 is a potent PKC inhibitor with IC50 of 7.9 nM, 2.3 nM, and 6.2 nM for PKC (Rat brain), PKCα, and PKCβ1, respectively. Also a potent inhibitor of JAK2 and Flt3.
Targets JAK2 [2] FLT3 [2] PKCα [1] PKCβ1 [1] PKC (Rat brain) [1]
IC50 2.3 nM 6.2 nM 7.9 nM
In vitro Go6976 have no effect on the kinase activity of the Ca(2+)-independent PKC subtypes delta, epsilon, and zeta. [1] Beside WT JAK2, Go6976 also inhibits the mutant forms (JAK2 V617F and TEL-JAK2) found in haematological malignancies, and has activity against mutant forms of FLT3. In AML cells, Go6976 reduces the survival to 55% of control in FLT3-ITD cases and to 69% in FLT3-WT samples.[2] Go 6976 potently inhibits HIV-1 induction by Bryostatin 1, tumor necrosis factor alpha, and interleukin 6. [3]
In vivo Go6976 (2.5 mg/kg i.p.), as a PKD inhibitor, effectively prevents LPS/D: -GalN-induced acute liver injury by inhibition of MAPKs activation to reduce TNF-α production, and significantly improves the survival of LPS/D-GalN-challenged mice. [4]

Protocol(Only for Reference)

Kinase Assay:


PKC Activity Assay In brief, for measuring PKCα, and PKCβ1 and PKC from rat brain, the assay mixture of 200 μl contains 50 mM HEPES (pH7.5), 5 mM MgCl2, 1 mM EDTA, 1.25 mM EGTA, 1.32 mM CaC12, 1 mM dithiothreitol, 1 μg of phosphatidylserine, 0.2 μg of diolein, 40 μg of histone Hi, 10 μM [γ-32P]ATP (1 μCi/ml), and 5-10 units (pmol of Pi/min) of PKC. Assays are started by the addition of [γ-32P]ATP, incubated for 5 min at 30 °C, stopped by the addition of 2 ml of 8.5% H3PO4, filtered through 0.45-μm nitrocellulose filters, and evaluated by scintillation counting.

Cell Assay:


Cell lines Primary AML cells
Concentrations 1 μM
Incubation Time 48 hours

Cells are suspended at 2 × 105 per point in 200 μl RPMI/10% FCS. The inhibitor under investigation is added at the appropriate concentration and the cells incubated for 48 h at 37°C, 5% CO2. MTS activity is measured by CellTiter kit according to the manufacturers instructions. Results are expressed as a percentage of control (cells without inhibitor).

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×  mouse Km(3)  = 11.2 mg/kg
