|Description||VE-822 is an ATR inhibitor with IC50 of 19 nM in HT29 cells.|
|Features||The first ATR-targeted drug candidate with high selectivity for ATR.|
VE-822 (80 nM) attenuates ATR signaling pathway and reduces survival in tumor cells in response to XRT and gemcitabine. VE-822 (80 nM) attenuates ATR signaling in normal cells without enhancing radiation and gemcitabine killing in normal cells. VE-822 (80 nM) increases XRT-induced residual γH2AX and 53BP1 foci compared with XRT in MiaPaCa-2 and PSN-1 cells. VE-822 (80 nM) pre-treatment decreases Rad51 foci after XRT in MiaPaCa-2 and PSN-1 cells. VE-822 (80 nM) alone increases the G1-phase-fraction in MiaPaCa-2 and PSN-1 cells. VE-822 (80 nM) abrogates XRT enriched G2/M-phase-fraction in MiaPaCa-2 and PSN-1 cells. VE-822 has little effect alone, while VE-822 (80 nM) combined with XRT and/or gemcitabine enhances early and late apoptosis in PSN-1 cells that is strongest in the triple combination.  VE-822 increases tumor response to DNA damaging agents associated with blockade of pChk1 Ser345. 
|In vivo||VE-822 (60 mg/kg) inhibits phospho-Ser-345-Chk1 in mice bearing PSN-1 tumors after DNA-damaging agents. VE-822 (60 mg/kg) combined with XTR doubles the time for tumors to grow to 600 mm3 of XRT alone in mice bearing both PSN-1 and MiaPaCa-2 tumors. VE-822 (60 mg/kg) added to the combination of gemcitabine and XRT substantially prolongs the tumor growth delay compared with the Gem+XRT1 group n mice bearing both PSN-1 tumors. VE-822 (60 mg/kg) combined with XRT1 increases uptake in tumors by 44% compared with XRT1, suggesting that addition of VE-822 increased γH2AX phosphorylation and persistence of DNA damage caused by XRT. |
|In vitro||DMSO||36 mg/mL (77.66 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
5% DMSO+45% PEG 300+H2O
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.

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.
