Rabeprazole-d3 sodium the deuterium labeled Rabeprazole sodium. Rabeprazole sodium (LY307640 sodium) is a second-generation proton pump inhibitor (PPI) that irreversibly inactivates gastric H+/K+-ATPase. Rabeprazole sodium induces apoptosis. Rabeprazole sodium acts as an uridine nucleoside ribohydrolase (UNH) inhibitor with an b>IC50 of 0.3 μM. Rabeprazole sodium can be used for the research of gastric ulcerations and gastroesophageal reflux[1][2][3].
