|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.|
|In vitro||Go6976 have no effect on the kinase activity of the Ca(2+)-independent PKC subtypes delta, epsilon, and zeta.  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. Go 6976 potently inhibits HIV-1 induction by Bryostatin 1, tumor necrosis factor alpha, and interleukin 6. |
|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. |
|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 lines||Primary AML cells|
|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).
|Animal Models||LPS/D-GalN-challenged mice|

Erk5 activation depends on Mek5, classical PKC and Mek1/2. MOVAS cells were serum-starved overnight and then treated for 1 h if not indicated otherwise with inhibitors targeting Jnk (SP600125, 10 μM), p38 (SB203580, 10 μM), Mek1/2 (CI-1040, 3 μM), Jak2 (AG490, 10 μM), Src (SU6656, 0.5 μM), Go6983 (PKC, 1 μM), Gö6976 (classical PKC, 1 μM), proteasomes (MG132, 25 μM), TPA (100 ng/ml for 15 min to activate PKCs or overnight to inhibit) and Mek5 (BIX02189, 1 μM), as well as Ca2 + chelators (EDTA, 2 mM; BAPTA-AM, 10 μM; both with 30 min preincubation), followed by stimulation with 20 ng/ml PDGF-BB for 10 min. Total cell lysates (TCL) were prepared and subjected to SDS-PAGE. Erk5 and PDGFRβ activities were measured by band shift and Tyr857 phosphorylation, respectively, using immunoblotting. Panel E and G show representative immunoblots.

Inhibition of InlB-mediated entry by a chemical inhibitor of PKC-α. HeLa cells were treated with the indicated concentrations of the compound Go6976 699 or with the vehicle DMSO for 45 min before assessment of bacterial entry or cell viability. (i). The effect of Go6976 treatment on entry of Listeria expressing InlB is shown. Data are means +/- SEM from three experiments. *, P < 0.05 compared to the DMSO only (-) condition. (ii). Go6976 treatment did not affect viability of HeLa cells as measured with MTT assays. Results are mean +/- SEM values from three experiments. (iii). Go6976 treatment did not reduce entry of E. coli strain HB101 expressing the invasin protein of Yersinia enterocolitica (inv+ HB101). Data are mean +/- SEM values from three experiments.
