ranges of drug concentration in plasma. In vivo screening of PEG prodrugs was done using a M109 syngeneic solid mouse tumor model. One of the PEG-daunorubicin prodrugs, with a half-life of 2 h, was evaluated in an in vivo solid tumor panel and found to be more efficacious against ovarian tumors (SKOV3) than equivalent amounts of daunorubicin.
基于三甲基锁内酯化反应,已经开发了一种合成含氨基化合物的聚乙二醇(PEG)前药的新方法。这些PEG修饰的双前体药物是水溶性的,通过选择性修饰修饰剂或引发剂,可以随意调节血浆半衰期,以产生宽范围的数值。实现了酯,碳酸酯和氨基甲酸酯官能团的简便合成,并将其与间隔基或芳香族骨架中的空间位阻或多或少地结合在一起,以实现血浆中药物浓度的可预测范围。使用M109同系实体小鼠肿瘤模型对PEG前药进行体内筛选。一种PEG-柔红霉素前药,半衰期为2小时,
