Ponesimod

Description: Ponesimod, formerly known as ACT-128800, is a potent, and orally bioavailable selective S1P(1) agonist. Ponesimod activated S1P(1)-mediated signal transduction with high potency (EC(50) of 5.7 nM) and selectivity. Ponesimod prevented edema formation, inflammatory cell accumulation, and cytokine release in the skin of mice with delayed-type hypersensitivity. Ponesimod also prevented the increase in paw volume and joint inflammation in rats with adjuvant-induced arthritis. Ponesimod may represent a new therapeutic approach in lymphocyte-mediated autoimmune diseases. References: Juif PE, Hoch M, D'Ambrosio D, Dingemanse J.
