Sildenafil is a Phosphodiesterase 5 Inhibitor with IC50 of 5.22 nM.
Sildenafil is a selective inhibitor of PDE5A (the type 5 cGMP phosphodiesterase) which catalyzes the hydrolysis of 3',5'-cyclic guanosine monophosphate (cGMP). As a PDE5 inhibitor, Sildenafil has been reported to enhance neuro-, synapto- and angiogenesis in rat models of stroke and also is reported to be a mild vasodilator. Sildenafil has also been shown to prevent indomethacin-induced small intestinal ulceration formation through an NO/cGMP- dependent mechanism.
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。
