Fase 3. \ n Atividade biológica AZD9291 mostra inibição significativamente mais potente da proliferação em linhas de células EGFR mutantes em comparação com o tipo selvagem in vitro. AZD9291 (5 mg / kg po) causa regressão profunda de tumores em modelos de tumor EGFRm + (PC9) e EGFRm + / T790M (H1975) com inibição profunda da fosforilação de EGFR e vias de sinalização a jusante chave, como AKT e ERK in vivo.

Cells are seeded (10000 cells/well) in growth medium in Corning black, clear- bottomed 384-well plates and incubated at 37°C with 5% CO2 overnight. Cells are acoustically dosed using an Echo 555, with compounds serially diluted in 100% DMSO. Plates are incubated for a further 2h, then following aspiration of medium, 40μL lx lysis buffer is added to each well. Greiner black high bind 384-well plates are coated with capture antibody and then blocked with 3% BSA. Following removal of block, 15μL of lysate are transferred to the Greiner black high bind 384-well plates and incubated for 2 hours. Following aspiration and washing of the plates with PBS, 20μL, of detection antibody were added and incubated for 2 hours. Following aspiration and washing of the plates with PBS, 20μL of QuantaBlu fluorogenic peroxidase substrate are added and incubated for 1 hour. 20μL QuantaBlu stop solution are added to plates and fluorescence read on an Envision plate reader using Excitation 352nm wavelength and emission 460nm wavelength. The data obtained with each compound is exported into a suitable software package to perform curve fitting analysis. From this data an IC50 value is determined by calculation of the concentration of compound that is required to give a 50% effect.

Por exemplo, para modificar a dose de resveratrol usada para um camundongo (22,4 mg / kg) para uma dose baseada na BSA para um rato, multiplique 22,4 mg / kg pelo fator Km para um camundongo e, em seguida, divida pelo fator Km para um rato. Este cálculo resulta em uma dose equivalente de rato para o resveratrol de 11,2 mg / kg.
