Elaiophylin大环内脂类抗菌素,作用于恶性疟原虫K1a 和布氏布锥虫GUTat 3.1 品系,具有抗原生动物活性,IC50分别为370 ng/mL和460 ng/mL。
Elaiophylin shows antiprotozoal activity against Plasmodium falciparum K1a and Trypanosoma brucei brucei GUTat 3.1 strains with IC50 of 0.36 μM and 0.45 μM, respectively. Elaiophylin shows shown cytotoxicity against mammalian tumor cells, protozoa, nematodes and antibacterial activity aganst gram-positive bacteria. The compound has also displayed immunosuppressive activity through inhibition of B-cell stimulation and inhibiting proliferation of lymphocytes stimulated by mitogens. Elaiophylin has been found to have antihelminthic to inhibit nitric oxide synthesis.
0 -10 μg/mL
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。
