Laquinimod是一种中枢神经系统(CNS)免疫调节剂。0.1-1 μM Laquinimod 处理不影响外周血单核细胞(PBMC)活性。通过在健康对象和复发缓解型多发性硬化症(RRMS)患者的PBMC中进行大规模基因表达芯片分析 ,显示 Laquinimod 抑制与抗原呈递及相应炎症通路相关的基因表达。Laquinimod作用于CD14+ 和 CD4+细胞,诱导Th2反应激活,作用于CD8+细胞,抑制增殖。
Laquinimod is a potent immunomodulator. Phase 3.
溶于PBS, ~1 μM
0.16, 1.6 和 16 mg/kg/day每天皮下注射
动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 A的Km系数 | |
例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
