| Bioactivity | ASP7663 is an orally active and selective TRPA1 agonist. ASP7663 exerts both anti-constipation and anti-abdominal pain actions[1][2]. | ||||||||||||
| Invitro | ASP7663 concentration dependently increases intracellular Ca2+ concentration in human, rat, and mouse TRPA1 expressed in HEK293 cells in a similar manner, with respective EC50 values (95% confidence interval [CI]) of 0.51 (0.40–0.66), 0.54 (0.41–0.72), and 0.50 (0.41–0.63) μmol/L[1].ASP7663 concentration-dependently stimulates 5-HT release from QGP-1 cells, a lineage of TRPA1-expressing EC cells, with an EC50 value of 72.5 (52.6–99.9) μmol/L[1]. | ||||||||||||
| In Vivo | ASP7663 significantly improves the loperamide-induced delay in colonic transit in mice[1]. ASP7663 (orally, 0.3 and 1 mg/kg) significantly shortens the prolonged bead expulsion time caused by loperamide[1].ASP7663 (orally, 1 and 3 mg/kg) exhibits inhibitory effects on colorectal distension in rat[1].
