Leupeptin hemisulfate is a reversible inhibitor of trypsin-like and cysteine proteases such as calpain.
Leupeptin hemisulfate is a reversible inhibitor of trypsin-like and cysteine proteases such as calpain which has been shown to inhibit cathepsins B, H, L, and S, calpain, and trypsin.
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。
