Cisapride-d6

Cisapride-d6 is intended for use as an internal standard for the quantification of cisapride (Cay-21657) by GC- or LC-MS. Cisapride is an agonist of serotonin (5-HT) receptor subtype 5-HT4 (IC50 = 0.483 µM in COS-7 cells expressing the human receptor). It induces relaxation of precontracted isolated rat esophageal thoracic muscularis mucosae preparations (EC50 = 102.33 nM). Cisapride (0.5 mg/kg) increases the rate of gastric emptying in rats. It is also a human ether-a-go-go related gene (hERG) channel blocker that binds to hERG channels with an IC50 value of less than 1 µM in a fluorescence polarization assay. Formulations containing cisapride have previously been used in the treatment of nocturnal heartburn associated with gastroesophageal reflux disease.Formal Name: rel-4-amino-5-chloro-N-[1-[(3R,4S)-3-(4-fluorophenoxy)propyl-d6]-3-methoxy-4-piperidinyl]-2-methoxy-benzamide.
