General description

Tenatoprazole is a novel proton pump inhibitor with an imidazopyridine backbone. It has seven-fold longer plasma half-life. It is also called as 5-methoxy-2-(4-methoxy-3,5-dimethyl-pyridin-2-ylmethanesulfinyl)-1H-imidazo[4,5-b]pyridine.Tenatoprazole is a member of the class of covalent proton pump inhibitors.

Biochem/physiol Actions

Tenatoprazole is a proton pump inhibitor. Tenatoprazole is an acid-activated prodrug that binds covalently to gastric H,K-ATPase, resulting in acid secretion inhibition. Tenatoprazole has a different structural class from omeprazole and most other proton pump inhibitors, with an imidazopyridine backbone rather than benzimidazole, which results in slower metabolism. Tenatoprazole thus has a long plasma half-life as compared to omeprazole, resulting in prolonged inhibition of acid secretion.
Tenatoprazole is used to maintain high diurnal and nocturnal pH levels. It prevents gastric H+,K+-ATPase with potency similar to omeprazole.

There is mounting evidence supporting the role of tryptophan metabolism via the kynurenine pathway (KP) in the pathogenesis of primary brain tumors. Under normal physiological conditions, the KP is the major catabolic pathway for the essential amino acid tryptophan. However
