[2H8]-Pantoprazole

Pantoprazole-d8 (BY1023-d8) is deuterium labeled Pantoprazole. Pantoprazole (BY10232) is an orally active and potent proton pump inhibitor (PPI)[1]. Pantoprazole, a substituted benzimidazole, is a potent H+/K+-ATPase inhibitor with an IC50 of 6.8 μM. Pantoprazole improves pH stability and has anti-secretory, anti-ulcer activities. Pantoprazole significantly increased tumor growth delay combined with Doxorubicin (HY-15142)[3][4].
