Background:
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[1].
Felcisetrag (0.03~3 mg/kg; s.c.) increases the colonic transit of carmine red dye, reducing the time taken for its excretion[1].Felcisetrag (0.03~10 mg/kg; intraduodenal administration) evokes a dose-dependent relaxation of the esophagus[1].Felcisetrag (10 and 30 μg/kg; p.o) produces an increase in contractility of the antrum, duodenum, and jejunum[1].
