Vonoprazan fumarate CAS:1260141-27-2 is a novel P-CAB (potassium-competitive acid blocker) that reversibly inhibits H+/K+, ATPase with IC50 of 19 nM (pH 6.5), controls gastric acid secretion. Vonoprazan Fumarate has a novel mechanism of action called potassium-competitive acid blockers (P-CABs) which competitively inhibits the binding the potassium ions to H+, K+-ATPase (also known as the proton pump) in the final step of gastric acid secretion in gastric parietal cells. Vonoprazan provides a strong and sustained acid section inhibitory effect. It is indicated for the treatment of gastric ulcer, duodenal ulcer and reflux esophagitis.
Vonoprazan fumarate CAS:1260141-27-2, the fumarate salt form of vonoprazan, is a pyrrole derivative and reversible potassium-competitive acid blocker (P-CAB), with potential antacid activity. Upon administration, vonoprazan specifically and competitively binds to the gastric hydrogen-potassium ATPase (H+/K+ ATPase) proton pump at or, more likely, near its potassium ion (K+) binding site and sterically inhibits K+ binding. This blocks the activation of the H+/K+ ATPase by K+, inhibits the proton pump and prevents gastric acid secretion, thereby lowering gastric acid levels.
