Product Introduction

Bioactivity
Description
Vonoprazan Fumarate (TAK438) , a novel potassium-competitive acid blocker, inhibits gastric acid secretion. Vonoprazan Fumarate (TAK438) inhibited H+,K+-ATPase activity in porcine gastric microsomes with IC50 value of 19 nM at pH 6.5.
Targets&IC50
H+, K+-ATPase:19 nM
In vitro
The inhibitory activity of Vonoprazan Fumurate was unaffected by ambient pH. The inhibition by Vonoprazan Fumurate was reversible and achieved in a K(+)-competitive manner, quite different from that by lansoprazole. Vonoprazan Fumurate exhibits porcine gastric H+ ,K+-ATPase activity in a concentration-dependent manner[4].
In vivo
Vonoprazan Fumurate, at a dose of 4 mg/kg (as the free base) orally, completely inhibited basal and 2-deoxy-d-glucose-stimulated gastric acid secretion in rats, and its effect on both was stronger than that of lansoprazole. Vonoprazan Fumurate increased the pH of gastric perfusate to a higher value than did lansoprazole or SCH28080, and the effect of Vonoprazan Fumurate was sustained longer than that of lansoprazole or SCH28080[4].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
