U0126-EtOH is a non-ATP competitive and selective inhibitor of MEK1 and MEK2 with IC50 values of 72nM and 58nM, respectively[1]. U0126-EtOH inhibits the activity of the ERK signaling pathway, thereby decreasing progesterone production and the expression of steroidogenic enzymes and steroidogenic factor 1 (SF1)[2]. U0126-EtOH has been widely used in parasitological research to inhibit the growth of Echinococcus granulosus in mice[3].
In vitro, U0126-EtOH treatment (0.5μM) for 24 hours led to a decrease in the phosphorylation level of ERK1/2 and the expression of cyclin D1 in H520 cells[4]. Treatment with 10μM U0126-EtOH in combination with 1μM Purmorphamine for 48 hours inhibited the activity of Rheumatoid arthritis (RA)-fibroblast-like synoviocytes (FLS) cells and altered the distribution of the cell cycle[5]. Treatment with 10μM U0126-EtOH for 8 hours significantly suppressed the invasion of A375 cells and reduced the secretion of uPA and MMP-9[6].
In vivo, U0126-EtOH treatment via a single tail vein injection of 10mg/kg alleviated acute renal failure induced by cisplatin in mice and reduced renal cell apoptosis[7]. Intraperitoneal injection of U0126-EtOH (30mg/kg) at 0 hour and 24 hours after reperfusion improved long-term neurological function in female rats following experimental stroke[8].

Protocol
| Cell experiment [1]: | |
|
Cell lines |
A375 cells |
|
Preparation Method |
A375 cells were cultured in minimal essential medium supplemented with 10% fetal bovine serum, sodium pyruvate, non-essential amino acids, 2mM l-glutamine, 60IU/ml penicillin, and 100IU/ml streptomycin at 37°C with 5% ambient CO2. The in vitro invasion assay was performed in a 24-well trans-well plate with 8μm pore size filter inserts coated with growth factor reduced Matrigel. Cells (5×104) in 500μl minimal essential medium in the absence or presence of different concentrations of U0126-EtOH (0, 1, 5, and 10μM) were plated into Matrigel-coated filter insert. A volume of 800μl of minimal essential medium in the absence or presence of different concentrations of U0126-EtOH (0, 1, 5, and 10μM) was added to the lower compartment of the invasion chamber. The chamber was incubated at 37°C for 8 h in 5% CO2. After incubation, the cells on the upper side of the insert filter were removed using cotton swabs. Invasion of A375 cells was measured. |

Reaction Conditions |
0, 1, 5, and 10μM; 8h |
|
Applications |
U0126-EtOH treatment reduced invasion of A375 cells in a dose-dependent manner. |
| Animal experiment [2]: | |
|
Animal models |
Male balb/c mice |
|
Preparation Method |
Male balb/c mice (6-week-old) were housed on a 12h light/dark cycle and had free access to food and water at 22°C. Cisplatin was dissolved in normal saline at a concentration of 2mg/ml and mice were given a single intraperitoneal injection of 20mg/kg cisplatin and control animals received same volume of normal saline. One hour before cisplatin administration, either vehicle (0.1% DMSO in normal saline) or U0126-EtOH (10mg/kg) was injected intravenously via tail vein. Mice were sacrificed at 24, 48, and 72 hours after cisplatin administration. Kidneys were collected and processed for histology. |
|
Dosage form |
10mg/kg; once; tail vein injection |
|
Applications |
U0126-EtOH treatment markedly alleviated acute renal failure induced by cisplatin in mice and reduced renal cell apoptosis. |
