A series of nitrobenzyl- and nitroimidazolylmethyl carbamate prodrugs of doxorubicin were prepared and evaluated for their potential use in nitroreductase (NTR) mediated gene-directed enzyme prodrug therapy (GDEPT). The carbamate prodrugs and doxorubicin were tested in a cell line panel comprising parental and NTR transfected human (SKOV3/SKOV3-NTR(neo), WiDr/WiDr-NTR(neo)), Chinese hamster (V79/V79-NTR(puro))
制备了阿霉素的一系列硝基苄基和硝基咪唑基甲基氨基甲酸酯前药,并评估了它们在硝基还原酶(NTR)介导的基因导向酶前药治疗(GDEPT)中的潜在用途。在包含亲本和NTR转染的人(SKOV3 / SKOV3-NTR(neo),WiDr / WiDr-NTR(neo)),中国仓鼠(V79 / V79-NTR(puro))的细胞系面板中测试了氨基甲酸酯前药和阿霉素的细胞系和鼠(EMT6 / EMT6-NTR(puro))细胞系对,并与已建立的NTR底物CB 1954(叠氮基二硝基苯甲酰胺)和类似的dibromomustard SN 29427比较。前药的低溶解度(3至39 microM )排除了在某些情况下针对亲本细胞系确定IC(50)值的可能性。在24小时内,添加了5%胎牛血清的培养基中,所有前药均不稳定,尽管未观察到阿霉素的释放。在人细胞系SKOV3和WiDr中,前药的毒性比阿霉素低20-> 336倍,而在V79细胞系(11->
