Biological Activity

GDC-0879 is a potent and selective B-Raf kinase inhibitor with an EC50 of 0.75 µM. GDC-0879 has been used in various research studies for its anti-cancer properties. In GDC-0879-treated mice, both cell line- and patient-derived BRAFV600E tumors exhibited stronger and more sustained pharmacodynamic inhibition (>90% for 8 hours) and improved survival compared with mutant KRAS–expressing tumors.

Protocol
Cell Experiment
Cell lines A375 and Colo205 cells
Preparation method GDC-0879 in vitro IC50 estimates for pMEK inhibition were determined using A375 and Colo205 cells. In brief, A375 or Colo205 cells were incubated with a range of GDC-0879 concentrations (from 0.5 nM to 6.75 μM) for 25 min. Cells were lysed, and the lysates were subjected to centrifugation at 16,100g for 30 min, and the level of total protein was determined using the Bradford method (Bradford, 1976). Enzyme-linked immunosorbent assay kits were used to determine pMEK1 and total MEK1 protein levels in a 96-well format (Tago Biosource International, Camarillo, CA). Samples were analyzed in duplicate at 20 μg of protein per well according to the protocol of the supplier. The optical densities obtained at 450 nm were converted to units per milliliter (for pMEK1) or nanograms per milliliter (for total MEK1) using a standard curve determined with recombinant pMEK1 or MEK1. The pMEK1/total MEK1 ratios were then calculated as units per nanogram. The IC50 estimates for pMEK1 inhibition were estimated by nonlinear regression using GraphPad Prism version 4.02 (GraphPad Software Inc., San Diego, CA).

Formulation 0.5% methylcellulose/0.2% Tween-80 (MCT)
Dosages A375 xenograft: 50, 100, 200mg/kg once daily / Colo205 xenograft:50, 100 mg/kg once daily
Administration oral gavage

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.
