2-PPA
Based on 1 Customer Validation
2-PPA is a lysosomal potassium and proton channel TMEM175 pore blocker. 2-PPA binds at a TMEM175 pore site to occlude potassium and proton ion permeation pathways. 2-PPA increases lysosomal macromolecule catabolism, accelerates macropinocytosis. 2-PPA binds to hepatic protein in covalent. 2-PPA can be used for the research of Parkinson's disease.

2-PPA (1-1000 μM) potently inhibits human TMEM175-mediated K+ flux, with an IC50 of 31 μM[1].
2-PPA binds as a pore blocker to the cytosolic region of the open-state human TMEM175 pore, occluding the ion permeation pathway via specific interactions with channel residues Ser45 and Ala42[1].
2-PPA (3-1000 μM) potently and selectively inhibits human TMEM175-mediated Kv3.1 currents in HEK293T cells, with an IC50 of 32 μM[1].
2-PPA (3-1000 μM) inhibits human TMEM175-mediated proton flux in HEK293T cells with an IC50 of 30 μM at pH 4.5[1].
2-PPA (300 μM; 1 h) accelerates lysosomal catabolism and macropinocytosis in wild-type MEFs, MIA PaCa-2, SH-SY5Y, PANC-1, and HeLa cells via specific inhibition of TMEM175[1].
2-PPA (300 μM; 1 h) stimulates lysosomal cathepsin B activity in wild-type MEFs via indirect modulation of lysosomal function, without directly altering cathepsin enzymatic activity[1].

Solvent & Solubility
DMSO : ≥ 100 mg/mL (587.48 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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 (protect from light). 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 (14.69 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 (14.69 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 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.
