PR-619是一种非选择性的,可逆的DUBs(去泛素化酶)抑制剂,EC50为1-20 μM。
(2,6-diamino-5-thiocyanatopyridin-3-yl) thiocyanate, also designated as PR-619, is a broad-range reversible and cell-permeable inhibitor of deubiquitylating enzyme (DUB), potently suppresses the activity of almost all cysteine protease DUBs, but shows selectivity toward DUBs over other proteases, such as calpain 1, or cathepsins. PR-619 induces (tumor) cell death with EC50 values in the low micromolar range .
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。
