|Description||Sapitinib (AZD8931) is a reversible, ATP competitive inhibitor of EGFR, ErbB2 and ErbB3 with IC50 of 4 nM, 3 nM and 4 nM in cell-free assays, more potent than Gefitinib or Lapatinib against NSCLC cell, 100-fold more selective for the ErbB family than MNK1 and Flt. Phase 2.|
AZD8931 shows different potency to NSCLC and SCCHN cell lines. AZD8931 has high sensitivity to PC-9 cells (EGFR activating mutation) with GI50 of 0.1 nM and low activity to NCI-1437 cells with GI50 above 10 μM. AZD8931 exhibits more potency against phospho-EGFR, phospho-erbB2 and phospho-erbB3 than either lapatinib or gefitinib in PE/CA-PJ41, PE/CA-PJ49, DOK and FaDu cells. 
|In vivo||AZD8931 reveals antitumor activity in BT474c, Calu-3, LoVo, FaDu and PC-9 xenografts. AZD8931 could reduce p-Akt, Ki67 expression and p-ERK in BT474c xenografts following acute treatment. AZD8931 also causes induction of the M30 apoptosis marker. Furthermore, AZD8931 shows greater proapoptotic effect compared with gefitinib and lapatinib in LoVo xenografts. |
Isolated kinase assays:The intracellular kinase domains of human EGFR and erbB2 are cloned and expressed in the baculovirus/Sf21 system. The inhibitory activity of AZD8931 is determined with ATP at Km concentrations (0.4 mM for erbB2 and 2 mM for EGFR) using the ELISA method.
|In vitro||DMSO||40 mg/mL (84.4 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
30% PEG400+0.5% Tween80+5% propylene glycol
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.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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.
