生物活性

产品描述	一种质子泵抑制剂;抑制猪胃H+/K+-ATPase酶活性的IC50值为6.2μM。
靶点	IC50:6.2μM (H+/K+-ATPase)
体外研究	Tenatoprazole inhibits hog gastric H+/K+-ATPase activity with almost equal potency to that of omeprazole (IC50=6.2 and 4.2 microM,respectively).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 2.6nmol/mg of the enzyme.
体内研究	Tenatoprazole inhibits basal gastric acid secretion in pylorus-ligated rats in a dose-dependent manner (ED50=4.2mg/kg p.o.).In gastric fistula rats, tenatoprazole (2.5 and 5mg/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.Maximum binding of tenatoprazole is 2.9nmol/mg of the enzyme at 2h 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.

推荐实验方法(仅供参考)

激酶实验：

The enzyme suspension (20mg/mL) is incubated at 37℃ in a buffer composed of 5mM Pipes/Tris (pH 6.95),2mM MgCl2,150mM KCl,3mg/mL of valinomycin,1mM acridine orange,in the presence of 0.1mM glutathione,in a SPEX spectrofluorometer for 5 min.Inhibitor (20mM),omeprazole or tenatoprazole,is added and fluorescence is measured by excitation at 490nm and emission at 530nm.After 60 s,ATP (2mM) is added to initiate acridine orange uptake as a measure of intra-vesicular acidification.

动物实验:

Rats:(R,S)-Tenatoprazole free form (50mg/kg) or (S)-tenatoprazole sodium salt hydrate (50mg/kg) is orally administered to dogs and the plasma level of tenatoprazole is measured as a function of time course.Similarly,(S)-tenatoprazole free form (100mg/kg) or (S)-tenatoprazole sodium salt hydrate (100mg/kg) is orally administered to dogs and the plasma level of tenatoprazole is measured as a function of time.
