| Description | NU 7026 is a novel specific DNA-PK inhibitor with IC50 of 0.23±0.01 μM, also inhibits PI3K with IC50 of 13±3 μM. |
| Target | DNA-PK:0.23 μM (IC50) PI3K:13 μM (IC50) |
| In Vitro | NU7026 (10 μM) potentiates ionizing radiation (IR) cytotoxicity [potentiation factor at 90% cell kill (PF90)=1.51±0.04] in exponentially growing DNA-PK proficient but not deficient cells[1]. NU7026 synergistically sensitizes I83 cells to Chlorambucil (CLB) 3.5-fold[2].NU7026, a novel inhibitor of the DNA repair enzyme DNA-dependent protein kinase (DNA-PK). At a dose of 10 μM, which is nontoxic to cells per se, a minimum NU7026 exposure of 4 h in combination with 3 Gy radiation is required for a significant radiosensitisation effect in CH1 human ovarian cancer cells[3]. |
| In Vivo | NU7026, a novel inhibitor of the DNA repair enzyme DNA-dependent protein kinase (DNA-PK). Following intravenous administration to mice at 5 mg/kg, NU7026 underwent rapid plasma clearance (0.108 L/h) and this is largely attributed to extensive metabolism. Bioavailability following interperitoneal (i.p.) and p.o. administration at 20 mg/kg is 20 and 15%, respectively[3]. |
| Cell Assay | I83 cells are plated in RPMI 1640 medium with 10% FBS (1.5×105 cells/mL) and treated with vehicle (DMSO), 5 μM CLB, CLB IC50, 10 μM NU7026, or the combination of both drugs for 0, 6, 24, and 48 h. Cell cycle distribution, apoptosis, DNA-PK phosphorylation, and γH2AX determination are determined, and they are expressed as a percentage of cells in each phase of the cycle. DNA content is analyzed with a FACSCalibur flow cytometer equipped with CellQuest software[2]. |
| Animal Admin | Mice[3] Female BALB/c mice are used. NU7026 is formulated in 10% DMSO and 5% Tween 20 in saline for i.p. and perorally (p.o.) administration at 20 and 50 mg/kg, respectively. For i.v. dosing at 5 mg/kg, NU7026 is formulated in 10% ethanol, 25% PEG 200 and 5% Tween 20 in saline. Control animals receive the vehicle alone. Groups of three mice are injected per time point. Blood is collected by cardiac puncture following transient anaesthesia with halothane at 0.083, 0.25, 0.5, 1, 2, 4, 6, and 24 h post administration. Following centrifugation at 1500 g for 2 min to obtain plasma, samples are stored at −20°C until analysis. For urinary excretion studies, NU7026 is administered at 5 mg/kg i.v. Urine is collected over 24 h in metabolic cages, and stored at −20°C until required. |
