Tenatoprazole sodium (TU-199 sodium) is a proton pump inhibitor; inhibits hog gastric H+/K+-ATPase with an IC50 of 6.2 μM. IC50: 6.2 μM (H+/K+-ATPase)[1]
Tenatoprazole inhibits hog gastric H+/K+-ATPase activity with almost equal potency to that of omeprazole (IC50=6.2 and 4.2 microM, respectively)[1]. Tenatoprazole is a prodrug of the proton pump inhibitor class. Tenatoprazole is converted to the active sulfenamide or sulfenic acid by acid in the secretory canaliculus of the stimulated parietal cell of the stomach. This active species binds to luminally accessible cysteines of the gastric H+/K+-ATPase resulting in disulfide formation and acid secretion inhibition. Tenatoprazole binds at the catalytic subunit of the gastric acid pump with a stoichiometry of 2.6 nmol/mg of the enzyme[2].
Tenatoprazole inhibits basal gastric acid secretion in pylorus-ligated rats in a dose-dependent manner (ED50=4.2 mg/kg p.o.). In gastric fistula rats, tenatoprazole (2.5 and 5 mg/kg i.d.) also inhibits gastric acid secretion stimulated by histamine, carbachol or tetragastrin. Furthermore, tenatoprazole prevents the formation of water-immersion restraint stress-, pylorus ligation- and indomethacin-induced gastric lesions, and mepirizole-induced duodenal ulcer in rats[1]. Maximum binding of tenatoprazole is 2.9 nmol/mg of the enzyme at 2 h after IV administration. The binding sites of tenatoprazole are in the TM5/6 region at Cys813 and Cys822. The bioavailability of tenatoprazole is two-fold greater in the (S)-tenatoprazole sodium salt hydrate form as compared to the free form in dogs[2].
