    Description

    U0126 is a potent, non-ATP competitive and selective MEK1 and MEK2 inhibitor, with IC50s of 72 nM and 58 nM, respectively. U0126 is an autophagy and mitophagy inhibitor[1][2][3][4].

    IC50 & Target[1]

    MEK2

    60 nM (IC50)

    MEK1

    70 nM (IC50)

    In Vitro

    Treatment with U0126 efficiently reduces progeny virus titers of all tested strains in A549 cells. While nM concentrations of U0126 are efficient to reduce H1N1v and H5N1 (MB1), μM concentrations of U0126 are required to reduce the virus titer of H5N1 (GSB) and H7N7. The EC50 values for U0126-EtOH against H1N1v are 1.2±0.4 μM in A549 cells and 74.7±1.0 μM in MDCKII cells[2].
    Rat hepatocarcinoma cells (FAO) stimulated by fetal calf serum (FCS) exhibits a significant proportion in S phase (32.62%) whereas U0126 strongly decreases the proportion of cells in S phase (9.92%) and increases the proportion of cells in G0-G1 phase and to a lesser extent in G2/M[3].

    In Vivo

    Mice are treated daily with U0126-EtOH (U0126; i.p., 10.5 mg/kg). In control experiment, tumor sizes are constant or slightly increase all over the kinetic. At the opposite, in all U0126-EtOH experiments, engraftment and early tumor growth are significantly decreased. Furthermore, a 60-70% reduction in the volume of tumors treated with U0126-EtOH is obtained 9 days after injection and thereafter[3].
    Rats are subjected to 120 minutes transient middle cerebral artery occlusion (tMCAO) and thereafter treated with the U0126-EtOH (U0126; i.p., 30 mg/kg) at 0 and 24 hours of reperfusion. After treatment with U0126-EtOH, the vasoconstriction to S6c is markedly reduced[4].

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
