| Description | Cobimetinib (GDC-0973) is a MEK1 inhibitor (IC50=4.2 nM) with selective and oral activity. Cobimetinib exhibits antitumor activity, inhibiting tumor cell proliferation and inducing apoptosis. |
| Targets & IC50 | MEK:0.9 nM |
| In vitro | METHODS: A panel of BRAF-mutant, RAS-mutant, or wild-type cell lines were treated with Cobimetinib for 96 h and cell viability was measured by Cell Death Detection ELISA Plus kit. RESULTS: Cobimetinib showed potent cellular potency in multiple tumor types, particularly in BRAF or KRAS mutant cancer cell lines. In a subset of tumor cell lines, 80% of BRAF-mutant lines (both V600E and non-V600E mutations) were sensitive to Cobimetinib (EC50<1 µmol/L), 54% of lines harboring KRAS or NRAS-carrying mutations were sensitive, and the remaining 35% of lines were sensitive. [1] METHODS: NB cell lines IMR-32, SHEP, and IMR-5 were treated with Cobimetinib (1 µM) for 4 h, and target protein expression levels were measured by Western Blot. RESULTS: Cobimetinib treatment induced dephosphorylation of c-RAF and ERK and increased phosphorylation of MEK. [2] |
| In vivo | METHODS: To assay antitumor activity in vivo, Cobimetinib (1-10 mg/kg) was administered orally to mice bearing A375.X1 or NCI-H2122 xenografts once daily for 21 days. RESULTS: In the A375.X1 BRAFV600E mutant melanoma xenograft model, treatment with a dose of Cobimetinib greater than 3 mg/kg resulted in an intense TGI, and in the NCI-H2122 KRASG12C mutant NSCLC xenograft model, treatment with up to 5 mg/kg Cobimetinib resulted in a moderate TGI, and treatment with 10 mg/kg approached tumor arrest.

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
