NS-398是一种COX-2抑制剂,抑制作用呈浓度依赖性。100μM NS-398不影响COX-1活性, 而抑制COX-2活性(IC50: 3.8 μM)。
NS-398, a COX-2 inhibitor, suppresses DOX-Induced Cytotoxicity and p53 Accumulation in U2OS and MCF-7 Cell Lines. NS-398 pre-treatment significantly reduces DOX-induced cytotoxicity in both cell lines. And on a line of human HSC, LI90, NS-398 demonstrated that alpha-smooth muscle actin (alpha-SMA) protein expression was inhibited in a dose-dependent manner.
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。
