Biological Activity

In vitro: EGF816 is a novel, covalent, mutant-selective EGFR inhibitor with nearly equipotent activity on both oncogenic (L858R and ex19del) and T790M-resistant mutations and good selectivity over WT EGFR. EGF816 potently inhibits the most common EGFR mutations L858R, Ex19del, and T790M in vitro. The cellular activity of EGF816 on EGFR mutants are assessed using three well-characterized cell lines, H3255, HCC827, and H1975, which harbor the L858R, Ex19del, and L858R/T790M mutations, respectively. After incubation with cells for 3 hours, EGF816 shows potent inhibition of pEGFR levels in H3255, HCC827, and H1975 with EC50 values of 5, 1, and 3 nmol/L, respectively. Cellular-based assays shows that EGF816 is selective toward mutant over WT EGFR. In vivo: EGF816 is well tolerated and possesses favorable physicochemical properties and good oral bioavailability in mice. It shows moderate volume of distribution and low to moderate clearance in rodents (30% and 35% of rat and mouse liver blood flow, respectively). In the dog, EGF816 shows high clearance and high volume of distribution. EGF816 also demonstrates antitumor activity in an exon 20 insertion mutant model. At levels above efficacious doses, EGF816 treatment leads to minimal inhibition of WT EGFR and is well tolerated. In single-dose studies, EGF816 provides sustained inhibition of EGFR phosphorylation, consistent with its ability for irreversible binding. EGF816 has a longer half-life in human than mouse and is currently being evaluated in phase I/II clinical trials in patients harboring EGFR mutations, including T790M.

Protocol
Cell Experiment
Cell lines H1975, H3255, HCC827, A431, and HaCaT cells
Preparation method H1975, H3255, HCC827, A431, and HaCaT cells are maintained in RPMI media supplemented with antibiotics and 10% FBS, maintained in a 37°C, 5% CO2 humidified incubator. After an overnight incubation in 384-well plates, serial diluted compounds are transferred to cells and incubated for 3 hours. HaCaT cells are stimulated with 10 ng/mL EGF (50 ng/mL EGF for A431) for 5 minutes. Cells are lysed in 1% Triton X-100 buffer containing protease and phosphatase inhibitors. Lysates are analyzed by sandwich ELISA utilizing goat anti-EGFR capture antibody, anti-phospho-EGFR(Y1173), and anti-rabbit HRP. Signal is measured by chemiluminescent detection.

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.
