GDC-0623 (RG 7421) and G-573 are able to prevent MEK phosphorylation by CRAF in vitro, and able to block MEK phosphorylation by BRAF(V600E)[1]. GDC-0623 (RG 7421) is potent, ATP-uncompetitive inhibitors of MEK1 but shows distinct shifts in cellular activity compared with the other two inhibitors, only 6-fold half-maximum effective concentration (EC50) decreases[2].

Protokoll
Flag-MEK1 mutants, S212P and S212A, are generated using the QuickChange site directed mutagenesis kit. Mammalian expression vectors for N-terminal Flag tagged MEK-1 are expressed in HCT116 cells. 1.8×106 HCT116 cells are plated in 10 cm plate and transfected on the following day with 17 μg of expression constructs using lipofectamine 2000. After 48 hours cells are treated with inhibitors for the indicated times, harvested and lysed in 100 μL cell extraction buffer. Cell lysates from each sample are analyzed by SDS-PAGE. Membranes are incubated with phospho-MEK S221, phospho-ERK1/2 and MEK1 primary antibodies and immunoreactive proteins are analyzed by SuperSignal West Pico Chemiluminescent Substrate.

Colo205 xenografts are established by inoculating 5×106 cells resuspended in Hank's Balanced Salt Solution (HBSS) subcutaneously (s.c.) in the rear right flank of 6-8 week old female nude (nu/nu) mice. NCI-H2122 xenografts are established by inoculating 1×107 cells resuspended in Hank's Balanced Salt Solution (HBSS) plus matrigel (growth factor reduced) s.c. in the rear right flank of 6-8 week old female nu/nu mice. Both A375 and MiaPaca-2 xenografts are initiated by transplanting 1 mm3 tumor fragments from their respective passaged tumors s.c. into the flank of athymic nu/nu mice. When tumors reached appr 200 mm3, mice are randomized and treated with daily (QD) oral gavage (PO) with either vehicle [methylcellulose 0.1% tween 80 0.1% (MCT)], GDC-0973 (at 10 mg/kg), GDC-0623 (RG 7421) (40 mg/kg), or G-573 (100 mg/kg). All doses of MEK inhibitors represented maximal tolerated doses (MTDs), resulting in no more than 15-20% body weight loss. Tumor volumes are determined using digital calipers using the formula (L×W×W)/2. Tumor growth inhibition (%TGI) iscalculated as the percentage of the area under the fitted curve (AUC) for the respective dose group per day in relation to the vehicle. Animal weights are recorded twice per week and mice are removed from study if body weights dropped ≥20%. Partial responses (PRs) are defined as any tumor demonstrating a ≥ 50% decrease in tumor volume, whereas complete responses (CRs) are defined as any tumor demonstrating 100% reduction in tumor volume at any point during the study.
