生物活性
MDL-860 is a 5-nitro-2-phenoxybenzonitrile that exerts broad-spectrum antipicornaviral activity (MIC50 from 0.1-1.5 μg/mL in HeLa cultures) by acting as an irreversible inhibitor against host phosphatidylinositol-4 kinase beta (PI4KB; PtdIns 4-kinase beta; PI4Kbeta; NPIK; PI4K92) via covalent modification of Cys646 located at the bottom of a surface pocket apart from the PI4KB active site. MCL-860 (MIC50 from 0.1-1.5 μg/mL in HeLa cultures). A pleconaril/MDL-860/oxoglaucine consecutive alternating administration (CAA), but not simultaneous daily treatment, is reported to be effective against coxsackievirus B1 infection without the development of drug resistance in newborn mice (75 mg/kg MDL-860 via s.c. every third day on the day following pleconaril and prior to oxoglaucine).

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
