Bioactivity | ACT-777991 is an orally active and selective CXCR3 antagonist. ACT-777991 has microsomes and hepatocytes stability across animal models. ACT-777991 inhibits the migration of activated T cells toward CXCL11[1]. |
Invitro | ACT-777991 在 CHO 细胞中抑制 hEGR,IC50 值为 26 μM[1]。ACT-777991(1 μM;45 分钟)在人类、大鼠和狗的微粒体和肝细胞中稳定[1]。ACT-777991(0.01-1 μM)抑制人和小鼠激活的 T 细胞向 CXCL11 的迁移,IC50 范围分别为 3.2-64 nM 和 4.9-21 nM[1]。ACT-777991(1 nM、5 nM、20 nM 和 50 nM)抑制 CXCR3 介导的人和小鼠 T 细胞趋化性[1]。 |
In Vivo | ACT-777991(0.5 mg/kg,1 mg/kg;静脉注射;单次剂量)在雄性 Wistar 大鼠 (14/156) 或 Beagle 犬 (5/15) 中具有低体内血浆清除率[1]。ACT-777991(0.006-2 mg/g 食物;口服;在 LPS 处理前 3 天开始给药,LPS 处理后 72 小时结束)剂量依赖性地抑制小鼠模型体内 CXCR3+ T 细胞的趋化性[1]。 Animal Model: |
