Vonoprazan Fumarate
Based on 6 publication(s) in Google Scholar
Vonoprazan Fumarate (TAK-438), a proton pump inhibitor (PPI), is a potent and orally active potassium-competitive acid blocker (P-CAB), with antisecretory activity. Vonoprazan Fumarate inhibits H+,K+-ATPase activity in porcine gastric microsomes with an IC50 of 19 nM at pH 6.5. Vonoprazan Fumarate is developed for the research of acid-related diseases, such as gastroesophageal reflux disease and peptic ulcer disease.

Biological Activity
IC50: 19 nM (porcine gastric H+,K+-ATPase, at pH 6.5)[2]
Vonoprazan (0.1 nM-10 μM; 30 minutes) exhibits porcine gastric H+ ,K+-ATPase activity in a concentration-dependent manner[2].
Vonoprazan does not inhibit Na+,K+-ATPase activity, even at concentrations 500 times higher than their IC50 values against gastric H+,K+-ATPase activity[2].

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 (5.42 mM); Clear solution
