| Enzyme Assay |
After 30 minutes on ice, cells are suspended in hypotonic buffer (9 mM HEPES, pH 7.8, 4.5% (v/v) dextran, 4.5 mM MgCl2, and 5 mM DTT) at 1.5 × 107/mL. Subsequently, 9 vol of isotonic buffer (40 mM HEPES, pH 7.8, 130 mM KCl, 4% (v/v) dextran, 2 mM EGTA, 2.3 mM MgCl2, 225 mM sucrose, and 2.5 mM DTT) is added. 2 mL of ice-cold 10% (w/v) TCA + 10% (w/v) sodium pyrophosphate is added to end the reaction, which was initiated by adding 300 µL cells to 100 µL 300 µM NAD+ containing [32P]-NAD+. The 32P-labelled ADP-ribose polymers that precipitate after 30 minutes on ice are filtered, five times cleaned with 1% (v/v) TCA and 1% (v/v) sodium pyrophosphate, dried, and counted.

| Cell Assay |
The indicated doses of NU1025 are applied after the cells (D54 and U251 cells) are seeded at a density of 2,500 cells/well in 96-well plates. A dose of 0.5 Gy/min of 250 kVp X-rays is applied to the medium containing adherent cells. The control group consists of untreated cells. Cell proliferation is measured using the MTT assay after an incubation period of up to five days.

| Additional Infomation |
NU 1025 is a member of the class of quinazolines that is quinazolin-4(1H)-one substituted by a hydroxy group at position 8 and a methyl group at position 2. It has been shown to exhibit inhibitory activity against poly(ADP-ribose) polymerase. It has a role as an EC 2.4.2.30 (NAD(+) ADP-ribosyltransferase) inhibitor. It is a member of quinazolines and a member of phenols.
8-Hydroxy-2-methylquinazolin-4(3H)-one has been reported in Streptomyces with data available. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (11.81 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (11.81 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
