Siponimod is a potent and selective S1P1 receptor agonist with EC50 of 0.4 nM; >10,000 fold potency for S1P3.
Siponimod is extensively bound to rat, dog, monkey, and human plasma proteins (>99.9%). It shows high and passive permeability in a Caco-2 human cell permeability assay with no transporter-mediated efflux observed at the test concentrations of 0.5–50 μM.
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。
