AU-461

AU-461 is an orally active and reversible inhibitor of the gastric H⁺/K⁺ ATPase with IC₅₀ values for rabbit-derived and pig-derived enzymes are 12.15 μM and 4.20 μM respectively. AU-461 competes with activated cationic K⁺ (Kᵢ = 1.64 μM). AU-461 reduces both histamine-stimulated gastric acid secretion and basal gastric acid secretion in rats. AU-461 inhibits ulcer formation caused by ethanol or sodium hydroxide, and restores the plasma gastrin level to normal. AU-461 can be used for the study of peptic ulcers.
