Papaveroline
Based on 1 Customer Validation
Papaveroline is a Fyn tyrosine kinase inhibitor, Na+,K+-ATPase inhibitor with an IC50 of 0.20 mM, Mg2+-ATPase inhibitor, K+-activated pNPPase inhibitor with an IC50 of 1.51 mM, and apoptosis inducer. Papaveroline binds to the active site of Fyn tyrosine kinase and forms stable interactions with pocket amino acid residues. Papaveroline induces cell apoptosis, produces pycnotic and fragmented cell nuclei, and does not reduce intracellular ATP levels. Papaveroline is a dopamine-derived neurotoxin candidate associated with the pathogenesis of Parkinson's disease. Papaveroline can be used in the research of Alzheimer's disease and Parkinson's disease.

Descripciòn
IC50 & Target
|
Na+,K+-ATPase 0.2 mM (IC50, rat brain microsomal) |
K+-activated pNPPase 1.51 mM (IC50, rat brain microsomal) |
In Vitro
Papaveroline inhibits rat brain microsomal K+-activated pNPPase with an IC50 of 1.51 mM, which is less potent than its inhibition of rat brain microsomal Na+,K+-ATPase[2].
Papaveroline (75-100% inhibition; 10 min)-mediated inhibition of rat brain microsomal Na+,K+-ATPase is freely reversible, as enzyme activity returns to control levels following washing and resuspension of the enzyme[2].
Papaveroline (200-400 μM) acts as a simple linear noncompetitive inhibitor of rat brain microsomal Na+,K+-ATPase with respect to ATP, exhibiting an apparent Ki of 380.00 μM[2].
Papaveroline (300 μM) decreases the apparent affinity of rat brain microsomal Na+,K+-ATPase for Na+ by increasing the K0.5 by 65% without altering cooperative binding at the Na+ site or the enzyme's Vmax[2].
Papaveroline inhibits beef cardiac Na+,K+-ATPase with an IC50 of 0.76 mM, which is less potent than its inhibition of rat brain microsomal Na+,K+-ATPase[2].

Solvente y solubilidad
In Vitro:
DMSO : 100 mg/mL (353.01 mM; Need ultrasonic; 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.

In Vivo:
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 (8.83 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
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 (8.83 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
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.
