ASP7663 是具有口服活性的、选择性的TRPA1激动剂。ASP7663 具有抗便秘和抗腹痛的活性。
生物活性 | ASP7663 is an orally active and selectiveTRPA1agonist. ASP7663 exerts both anti-constipation and anti-abdominal pain actions[1][2]. |
体外研究 (In Vitro) | ASP7663 concentration dependently increases intracellular Ca2+concentration in human, rat, and mouse TRPA1 expressed in HEK293 cells in a similar manner, with respective EC50values (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].

体内研究 (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].
Animal Model: | CRD model (colorectal distension in rat)[1]. | Dosage: | 1 and 3 mg/kg. | Administration: | Orally. | Result: | Significantly reduced the number of abdominal contractions evoked during CRD at pressures of 30, 45, and 60 mmHg. ASP7663 also reduced the number of abdominal contractions by intravenous treatment. |
