Biological Activity

GDC-0973 is a potent and selective mitogen-activated protein (MAP)/extracellular signal-regulated kinase (ERK) kinase (MEK) inhibitor. GDC-0973 is known as mitogen activated protein kinase kinase (MAPKK). GDC-0973 is a key component of the RAS/RAF/MEK/ERK pathway, which is frequently activated in human tumors.

Cell Experiment
Cell lines Human 888MEL (BRAFV600E) mutant melanoma cell lines
Preparation method Plating cells in quadruplicate at a density of 3,000 per well in 384-well plates in normal growth medium and allowing to adhere overnight. Adding compounds in 10 concentrations based on a 3-fold dilution series. Using the CellTiter-Glo Luminescent Cell Viability Assay to measure cell viability 72 h later.
Concentrations ~10 μM
Incubation time 4 days
Animal Experiment
Animal models Human A375.X1 BRAFV600E mutant melanoma xenograft
Dosages 5 mg/kg/day
Administration orally daily (QD) for 2 1 consecutive days
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
