描述 | Ozanimod is a specific modulator of S1P1 and S1P5 receptors. It can inhibit the generation of cAMP induced by forskolin, and GTP-binding with EC50 values of 0.16 nM and 0.41 nM, respectively. The induction of S1P1 receptor sustained internalization and degradation could be observed post one-hour treatment with 1 μM Ozanimod in transfected HEK293T cells expressing S1P1 receptors. Oral dose of 1 mg/kg Ozanimod in mice, or 0.5 mg/kg in rat, induced dose-dependent, selective lymphopenia and rapid lymphocyte repopulation kinetics, with reduction of CD4+CCR7+, and CD8+CCR7+ T cells. Administration of 0.6 mg/kg Ozanimod for 14 days reduced ongoing disease symptoms in EAE model induced by immunization with MOG35–55 peptide. Also, a significant reduction of disease activity in TNBS-induced colitis could be achieved in rats dosed 0.3 or 1 mg/kg Ozanimod. Histological disease severity and inflammatory cytokine expression were both reduced in a naïve T-cell adoptive transfer model of colitis after therapeutic administration[1]. |
