Gastroesophageal Reflux Disease

Cisapride (R 51619) is an orally active, selective 5-HT₄ receptor agonist with an EC₅₀ of 140 nM. Cisapride also acts as an hERG potassium channel blocker with an IC₅₀ of 9.4 nM. Cisapride exerts gastrointestinal prokinetic effects by activating 5-HT₄ receptors, but it also blocks the hERG potassium channel responsible for the repolarization phase of cardiac action potentials, delaying repolarization and thus prolonging the action potential duration. Cisapride can be used in research related to gastrointestinal dysfunction, gastroesophageal reflux disease, functional dyspepsia, chronic gastritis, gastroparesis, ulcerative colitis and necrotizing enterocolitis.

Vonoprazan Fumarate (TAK-438), a proton pump inhibitor (PPI), is a potent and orally active potassium-competitive acid blocker (P-CAB), with antisecretory activity. Vonoprazan Fumarate inhibits H⁺,K⁺-ATPase activity in porcine gastric microsomes with an IC₅₀ of 19 nM at pH 6.5. Vonoprazan Fumarate is developed for the research of acid-related diseases, such as gastroesophageal reflux disease and peptic ulcer disease.

Zastaprazan (JP-1366) citrate is a Proton pump inhibitor and potent potassium-competitive acid blocker. Zastaprazan citrate can be used in the research of gastrointestinal inflammatory diseases or gastric acid-related diseases such as gastroesophageal reflux disease.

Cisapride (R 51619) monohydrate is an orally active, selective 5-HT₄ receptor agonist with an EC₅₀ of 140 nM. Cisapride monohydrate also acts as an hERG potassium channel blocker with an IC₅₀ of 9.4 nM. Cisapride monohydrate exerts gastrointestinal prokinetic effects by activating 5-HT₄ receptors, but it also blocks the hERG potassium channel responsible for the repolarization phase of cardiac action potentials, delaying repolarization and thus prolonging the action potential duration. Cisapride monohydrate can be used in research related to gastrointestinal dysfunction, gastroesophageal reflux disease, functional dyspepsia, chronic gastritis, gastroparesis, ulcerative colitis and necrotizing enterocolitis.

Cisapride-d₆ (R51619-d₆) is the deuterated-labeled Cisapride (HY-14149). Cisapride (R 51619) is an orally active, selective 5-HT₄ receptor agonist with an EC₅₀ of 140 nM. Cisapride also acts as an hERG potassium channel blocker with an IC₅₀ of 9.4 nM. Cisapride exerts gastrointestinal prokinetic effects by activating 5-HT₄ receptors, but it also blocks the hERG potassium channel responsible for the repolarization phase of cardiac action potentials, delaying repolarization and thus prolonging the action potential duration. Cisapride can be used in research related to gastrointestinal dysfunction, gastroesophageal reflux disease, functional dyspepsia, chronic gastritis, gastroparesis, ulcerative colitis and necrotizing enterocolitis.

Cisapride-¹³C,d₃ (R 51619-¹³C,d₃) is the deuterated, ¹³C-labeled Cisapride (HY-14149). Cisapride (R 51619) is an orally active, selective 5-HT₄ receptor agonist with an EC₅₀ of 140 nM. Cisapride also acts as an hERG potassium channel blocker with an IC₅₀ of 9.4 nM. Cisapride exerts gastrointestinal prokinetic effects by activating 5-HT₄ receptors, but it also blocks the hERG potassium channel responsible for the repolarization phase of cardiac action potentials, delaying repolarization and thus prolonging the action potential duration. Cisapride can be used in research related to gastrointestinal dysfunction, gastroesophageal reflux disease, functional dyspepsia, chronic gastritis, gastroparesis, ulcerative colitis and necrotizing enterocolitis.

ONO-8539 is an orally active prostanoid EP1 receptor antagonist with competitive, insurmountable binding and slow receptor dissociation for long-duration inhibition. ONO-8539 modulates afferent nerve function related to bladder activity, inhibits detrusor overactivity-related contractions, decreases nonvoiding contractions and voiding duration, and increases uroflow rate with ATP (HY-B2176)-induced detrusor overactivity. ONO-8539 attenuates acid-induced heartburn symptoms, extends time to first heartburn sensation, and prevents primary hypersensitivity after distal esophageal acidification. ONO-8539 can be used for the research of overactive bladder and gastroesophageal reflux disease.
