描述了一种新型c(RGDyK)靶向SN38前药的制备,该前药含有吲哚醌结构,用于生物还原触发药物释放。这种设计产生了一种靶向肿瘤细胞表面分子(αvβ3整合素)并在生物还原条件下释放药物的前药。前药设计有三个部分,即治疗药物SN38,作为药物释放触发器的吲哚醌结构和αvβ3整合素靶向肽c(RGDyK)。初步研究表明,SN38在一种生物还原酶(DT-diaphorase)的存在下释放。
Preparation of a novel c(RGDyK) targeted SN38 prodrug incorporating an indolequinone structure for bioreductively triggered drug release is described. This design yields a prodrug that targets surface molecules on tumor cells (αvβ3 integrins) and releases drug under bioreductive conditions. There are three moieties in the prodrug design, namely a therapeutic drug SN38, an indolequinone structure serving as a drug releasing trigger, and an αvβ3 integrin targeting peptide c(RGDyK). Preliminary studies showed that SN38 is released in the presence of a bioreductive enzyme (DT-diaphorase).
