|Description||NU7026 (LY293646) is a potent DNA-PK inhibitor with IC50 of 0.23 μM in cell-free assays, 60-fold selective for DNA-PK than PI3K and inactive against both ATM and ATR. NU7026 enhances G2/M cell arrest and apoptosis.|
NU7026 potentiates ionizing radiation induced cytotoxicity in a concentration-dependent manner in V3YAC and PARP-1+/+ cells. NU7026 completely abolishes potentially lethal damage recovery in growth-arrested cells. NU7026 inhibits DNA DSB repair by 56% in the V3YAC cell line.  NU7026 (10 μM) potentiates the growth inhibitory effects of idarubicin, daunorubicin, doxorubicin, etoposide, mAMSA, and mitoxantrone with PF50 values ranging from approximately 19 for mAMSA to approximately 2 for idarubicin in K562 cells. NU7026 (10 μM) also potentiates the growth inhibitory effect of etoposide in this leukemia cell line with a PF50 value of 10.53. NU7026 (10 μM) enhances the etoposide-induced cell cycle G2 blockade in K562 cells. NU7026 potentiates topo II poisons involves inhibition of nonhomologous end joining and a G2/M checkpoint arrest.  NU7026 (10 μM) exposure of 4 h in combination with 3 Gy radiation is required for a significant radiosensitisation effect in CH1 human ovarian cancer cells.  NU7026 (< 10 μM) plus chlorambucil has synergistic cytotoxic activity at nontoxic doses of NU7026 in a CLL cell line (I83) and in primary CLL-lymphocytes. NU7026 (10 μM) increases chlorambucil-induced G(2)/M arrest in I83 cells. NU7026 (10 μM) enhances chlorambucil -induced γH2AX throughout the cell cycle in the I83 cell line. NU7026 (10 μM) Increases chlorambucil-Induced apoptosis in the I83 cell line.  NU7026 (55 μM) results in a dramatic induction of telomere fusion in p53 null MEFs and significantly fewer telomere fusions in p53 and ligase IV double null MEFs. 
|In vivo||NU7026 (20mg/kg, i.v.) undergoes rapid plasma clearance (0.108/hour) in mice and this is largely attributed to extensive metabolism. Bioavailability following interperitoneal (i.p.) and p.o. administration of NU7026 at dose of 20 mg/kg is 20 and 15%, respectively. |

|In vitro||DMSO||1 mg/mL (3.55 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
1% DMSO+30% polyethylene glycol+1% Tween 80
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.
