|Description||Osimertinib (AZD9291) is an oral, irreversible, and mutant-selective EGFR inhibitor with IC50 of 12.92, 11.44 and 493.8 nM for Exon 19 deletion EGFR, L858R/T790M EGFR, and WT EGFR in LoVo cells, respectively. Phase 3.|
|Features||Orally bioavailable mutant-selective EGFR inhibitor that has been tested in Phase III clinical trials for treatment of Non-Small Cell Lung Cancer.|
AZD9291 shows significantly more potent inhibition of proliferation in mutant EGFR cell lines compared to wild-type in vitro. 
|In vivo||AZD9291(5mg/kg p.o.) causes profound regression of tumors across EGFRm+ (PC9) and EGFRm+/T790M (H1975) tumor models with profound inhibition of EGFR phosphorylation and key downstream signaling pathways such as AKT and ERK in vivo. |
|In vitro||DMSO||99 mg/mL warmed (198.15 mM)|
|Ethanol||43 mg/mL warmed (86.06 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
