Biological Activity

Description GDC-0623 (G-868) is a potent and ATP-uncompetitive MEK1 inhibitor with Ki of 0.13 nM. Phase 1.
Targets
MEK1 [1]
0.13 nM
In vitro
In vitro In a panel of mutant cancer cell lines, GDC-0623 inhibits cellular proliferation with EC50 of 4 nM, 53 nM, 11 nM, 18 nM and 94 nM for A375 (BRAFV600E), HCT116 (KRASG13D), COLO 205 (V600E), HT-29 (V600E), and HCT116 (G13D) cells, respectively. [1] In isogenic KRAS HCT116 and mutant KRAS SW620 colon cells, GDC-0623 upregulates BIM via its loss of phosphorylation at Ser69. GDC-0623 plus ABT-263 induces a synergistic cell apoptosis. [2]
Kinase Assay In vitro Kinase assays
0.14 μM of purified inactive recombinant MEK-1 (Upstate) protein is preincubated with inhibitors in 15 μL of kinase buffer including (20 mM MOPS pH7.2, 25 mM beta glycerol phosphate, 5 mM EGTA, 1 mM sodium orthovanadate, 1 mM DTT, 100 μM ATP, 15 mM MgCl2). After incubating 10 minutes at 30°C, 1 ng of BRAF, CRAF or BRAF V600E combined with 0.5 μg of inactive recombinant ERK2 is added to the reaction in total volume of 20 μL. After incubating 30 minutes at 30°C the reaction is stopped by adding Laemmle sample buffer. Enzyme activity is measured by determining level of phosphor-MEK by SDS-PAGE. Immunoreactive proteins are visualized with SuperSignal West Pico Chemiluminescent Substrate.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
