A cell-permeable pyridyl methylsulfinyl benzimidazole compound that acts as selective proton pump inhibitor. Behaves as a prodrug by undergoing an acid-catalyzed rearrangement to a thiol-reactive cationic sulfenamide that inhibits (H+, K+)-ATPase in the gastric milieu. An aryl hydrocarbon-like inducer of cytochrome P450 secretion in human liver.

Studies both in vivo and in vitro have shown that substituted benzimidazoles inhibit the stimulation of acid secretion produced by dibutyryl cyclic AMP and histamine. Furthermore, the results differ from those produced by H2 antagonists and anticholinergic agents in that

The gastric H+,K+ ATPase--the gastric acid pump--is the molecular target for the class of antisecretory drugs called the proton-pump inhibitors (PPIs). These compounds--omeprazole, lansoprazole, and pantoprazole--contain, as their core structure, 2-pyridyl methylsulfinyl benzimidazole. The H+,K+ ATPase is a heterodimer composed

The vesicular gastric H,K-ATPase catalyzes an electroneutral H for K exchange allowing acidification of the intravesicular space. There is a total of 28 cysteines present in the alpha subunit of the gastric H,K-ATPase, of which 10 are found in the

The gastric H,K-ATPase is covalently inhibited by substituted pyridyl-methylsulfinyl-benzimidazoles, such as omeprazole, that convert to thiophilic probes of luminally accessible cysteines in the acid space. The K(+) competitive inhibitor, SCH28080, prevented inhibition of acid transport by omeprazole. In stably expressing
Omeprazole is a new drug used for its high efficiency as an inhibitor of gastric acid secretion. This substituted benzimidazole molecule had been shown to decrease several liver cytochrome P450-mediated monooxygenase activities both in vitro and in vivo. The present
