bis(pivaloyloxymethyl) ester prodrugs of Fosmidomycin and its acetyl analogue FR900098. The 3,4-dichlorobenzyl substituted derivative of Fosmidomycin proved to be about twice as active as the respective Fosmidomycin prodrug, however, less active than the corresponding FR900098 prodrug. Electron donating substituents as well as voluminous substituents led to a significant reduction of activity.
膦氧异羟肟酸膦酰胺霉素是治疗疟疾的候选药物,目前正在与克林霉素联合进行II期试验。为了获得更高的亲脂性化合物,我们最近合成了具有高抗疟活性的α-苯基取代的磷霉素衍生物。我们现在报告合成和体外抗疟原活性的膦酰胺霉素及其乙酰基类似物FR900098的芳基甲基取代的双(新戊酰氧基甲基)酯前药。证明磷霉素的3,4-二氯苄基取代的衍生物的活性约为相应的磷霉素前药的两倍,但是,其活性低于相应的FR900098前药。给电子取代基以及大量取代基导致活性的显着降低。
