Technical Data

Formula

C16H14FIN4O3
Molecular Weight 456.21 CAS No. 1168091-68-6
Solubility (25°C)* In vitro DMSO 91 mg/mL (199.46 mM)
Ethanol 6 mg/mL (13.15 mM)
Water ˂1 mg/mL
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 45% PEG 300 ddH2O
1.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 20 mg/ml clarified DMSO stock solution to 450 μL PEG 300, mix evenly to clarify it; then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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 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]
In vivo In vivo, GDC-0623 (40 mg/kg, p.o.) causes potent tumor growth inhibition (TGI) in mouse MiaPaCa-2 (120%), A375 (102%) and HCT116 (115%) xenografts. [1]

Protocol (from reference)

Kinase Assay:[1]
  • 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.
Animal Study:[1]
  • Animal Models

    Mice bearing MiaPaCa-2, A375 and HCT116 xenografts

  • Dosages

    40 mg/kg daily

  • Administration

    p.o.
