Product Description

Osimertinib (formerly AZD-9291 and mereletinib; trade name Tagrisso) is an oral bioavailable, irreversible/covalent, and mutant-selective EGFR inhibitor with potential antineoplastic activity. In LoVo cells, it inhibits WT EGFR, L858R/T790M EGFR, and Exon 19 deletion EGFR with IC50 values of 493.8 nM, 11.44, and 12.92 nM, respectively. Both the FDA and the European Commission approved it in 2017 for the treatment of cancer.

Biological Activity I Assay Protocols (From Reference)

Targets

EGFR^L858R (IC50 = 12 nM); EGFR^L858R/T790M (IC50 = 1 nM)

ln Vitro

AZD9291 exhibits a noticeably stronger suppression of proliferation in mutant EGFR cell lines when compared to wild-type in vitro. [2]

ln Vivo

AZD9291 (5 mg/kg p.o.) significantly inhibits EGFR phosphorylation and important downstream signaling pathways like AKT and ERK, leading to a significant regression of tumors in EGFRm+ (PC9) and EGFRm+/T790M (H1975) tumor models in vivo.

Enzyme Assay

In Corning black, clear-bottomed 384-well plates, 10,000 cells are seeded per well in growth medium, and the plates are then incubated for an entire night at 37°C with 5% CO2. Compounds are serially diluted in 100% DMSO and used to acoustically dose cells using an Echo 555. After aspirating the medium and incubating the plates for an additional two hours, 40μL of lysis buffer is added to each well. Greiner black high bind 384-well plates are blocked with 3% BSA after being coated with capture antibody. After the block is removed, 15μL of lysate is added to the Greiner black high bind 384-well plates, and the plates are incubated for two hours. Detection antibody (20μL) was added and the plates were incubated for two hours after aspiration and PBS washing. Aspiration and PBS washing are followed by the addition of 20μL of QuantaBlu fluorogenic peroxidase substrate and an hour of incubation. Add 20μL of QuantaBlu stop solution to each plate, and use an Envision plate reader to read the fluorescence at 352 nm for excitation and 460 nm for emission. A suitable software program is used to export the data obtained with each compound and perform curve fitting analysis. By calculating the compound concentration necessary to produce a 50% effect, an IC50 value is obtained from this data.

Cell Assay

In vitro, AZD9291 shows significant suppression of EGFR phosphorylation in EGFRm+ (e.g., PC9; < 25 nM) and EGFR m+/T790M (e.g., H1975; < 25 nM) cell lines, but much less activity against wild-type EGFR lines (e.g., LoVo; > 500 nM). In vitro, AZD9291 continuously demonstrated a much more powerful suppression of proliferation in mutant EGFR cell lines when compared to wild-type.

Animal Protocol

5 mg/kg; p.o

EGFRm+ and EGFRm+/T790M transgenic mice

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
