Amelparib
Based on 1 Customer Validation
Amelparib (JPI-289 free base) is a potent, orally active, and water-soluble inhibitor of PARP-1. Amelparib inhibits PARP-1 activity (IC50=18.5 nM) and cellular PAR formation (IC50=10.7 nM) in the nanomolar range. Amelparib is a potential neuroprotective agent. Amelparib has the potential for the research of acute ischaemic stroke.

Biological Activity
IC50: 18.5 nM (PARP-1)[1].
Amelparib (0.001 mM-1 mM; 2 h) dose-dependently reduces the number of apoptotic cells in cortical neurons induced by hypoxia for 24 h and 48 h[1]. Amelparib (0, 0.01, 0.1 and 1 mM; 2 h) dose-dependently reduces the increased PARP activity in cortical neurons, the expression of cleaved caspase-3 in cortical neurons subjected to 6 h of hypoxia, and the levels of HIF-1α and PAR in cortical neurons subjected to 2 h of hypoxia[1].

-
Cell Line:PCCNs
-
Concentration:0, 0.01, 0.1 and 1 mM
-
Incubation Time:2 h
-
Result:Decreased the levels of HIF-1α, PAR, AIF, and cytochrome c at 2 h of administration dose-dependently.
Reduced the expression of cleaved caspase-3 in the case of 6 h administration dose-dependently.
Amelparib (10 mg/kg, i.v.; single dose 2 or 8 h after MCAO) reduces mean infarct size and alleviates brain swelling in male SD rats[2].
Amelparib (10 mg/kg, i.v.; single dose 2 h after MCAO) reduces apoptosis of penumbra cells in male SD rats[2].

Solvent & Solubility
DMSO : 100 mg/mL (291.19 mM; ultrasonic and adjust pH to 2 with 1M HCl; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (7.28 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.5 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (7.28 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.5 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
