生物活性:
U0126 (U0126-EtOH) 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.

体内研究:
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. 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.Animal Model:Athymic female nude mice (SWISS, nu/nu).
Dosage:10.5 mg/kg.
Administration:Intraperitoneal injection daily.
Result:Inhibited tumor growth.
Animal Model:Twelve-week-old female Wistar rats (250 to 265 g).
Dosage:30 mg/kg.
Administration:Intraperitoneally.
Result:The vasoconstriction to S6c is markedly reduced.

体外研究:
Treatment with U0126-EtOH (U0126) efficiently reduces progeny virus titers of all tested strains in A549 cells. While nM concentrations of U0126-EtOH are efficient to reduce H1N1v and H5N1 (MB1), μM concentrations of U0126-EtOH 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.Rat hepatocarcinoma cells (FAO) stimulated by fetal calf serum (FCS) exhibits a significant proportion in S phase (32.62%) whereas U0126-EtOH (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.
