产品描述: Ponesimod (ACT-128800) is a potent, selective and orally active agonist of S1P1, with an IC50 of 6 nM in a radioligand binding assay. Ponesimod activates S1P1-mediated signal transduction with high potency (EC50=5.7 nM). Ponesimod can protect against lymphocyte-mediated tissue inflammation |

体内研究:
Ponesimod (30 and 175 mg/kg; once daily p.o. for 8 d) prevents delayed-type hypersensitivity in mice. Ponesimod (30 mg/kg by gavage 3 h before and 6 h after adjuvant injection followed by 100 mg/kg/day by administration as food admix for 18 days) prevents adjuvant-induced arthritis in rats. Ponesimod (0.3-100 mg/kg; a single oral gavage) causes a dose-dependent reduction in lymphocyte count, with a plateau effect being reached at 3 mg/kg in rats. Ponesimod (100 mg/kg; once daily oral gavage for 7 d) results in a lymphocyte count reduction to 1900 lymphocytes/μL, and this effect is maintained over the entire 7 days studies. Lymphocyte count returned to baseline levels within 48 h after discontinuation of dosing. |
