Felcisetrag

Research use only, not for human use.

Felcisetrag (TD-8954) is a potent and selective orally active 5-HT4 agonist with gastrointestinal prokinetic properties.

Felcisetrag (TD-8954) is an orally active, potent and selective 5-HT4 receptor agonist with gastrointestinal prokinetic properties. Felcisetrag has high affinity (pKi =9.4) for human 5-HT4(c) receptors.

Felcisetrag produces an elevation of cAMP in HEK-293 cells expressing the h5-HT4(c) receptor (pEC50?=?9.3), and contracts the guinea pig colonic longitudinal muscle/myenteric plexus preparation (pEC50?=?8.6). Felcisetrag has moderate intrinsic activity in the vitro assays.

Felcisetrag (0.03~3?mg/kg; s.c.) increases the colonic transit of carmine red dye, reducing the time taken for its excretion.Felcisetrag (0.03~10?mg/kg; intraduodenal administration) evokes a dose-dependent relaxation of the esophagus.Felcisetrag (10 and 30?μg/kg; p.o) produces an increase in contractility of the antrum, duodenum, and jejunum.Animal Model:Guinea pigsDosage:0.03~3?mg/kg Administration:S.c.Result:Increased the colonic transit of carmine red dye, reducing the time taken for its excretion.Animal Model:Rats Dosage:0.03~10?mg/kg Administration:Intraduodenal administration Result:Evoked a dose-dependent relaxation of the esophagus.Animal Model:Dogs Dosage:10 and 30?μg/kg Administration:P.o Result:Produced an increase in contractility of the antrum, duodenum, and jejunum.
