Tegoprazan, a potassium-competitive acid blocker, is a potent, oral active and highly selective inhibitor of gastric H/K-ATPase that could control gastric acid secretion and motility, with IC50 values ranging from 0.29-0.52 μM for porcine, canine, and human H/K-ATPases in vitro.
IC50&Target
IC50: 0.29-0.52 μM (H/K-ATPase).
体外研究
Tegoprazan inhibits porcine, canine, and human H/K-ATPase activity. Tegoprazan inhibits gastric H/K-ATPase in a potassium-competitive and reversible manner. Tegoprazan (3 μM) inhibits 86% of H/K-ATPase activity, whereas the inhibition is decreased to 34% after the dilution of Tegoprazan concentration to 0.15 μM.
体内研究
Tegoprazan (1.0 mg/kg, p.o.) potently and completely inhibits histamine-induced gastric acid secretion in dogs. Tegoprazan (1.0-3.0 mg/kg, p.o.) reverses the pentagastrin-induced acidified gastric pH to the neutral range. Tegoprazan (3 mg/kg, p.o.) immediately evokes a gastric phase III contraction of the migrating motor complex in pentagastrin-treated dogs.
