or 2 deficient tumours, we designed a series of molecules containing a 1,2,3-triazene moiety tethered to a PARP targeting scaffold. A cell-based selectivity assay involving a BRCA2-deficient Chinese hamster cell line and its corresponding BRCA2 wild type transfectant, was used to predict the PARP targeting potential of the latter agents. The results showed that adding a DNA damaging function to the PARP
为了增强BRCA1或2型缺乏肿瘤中聚(ADP-核糖)聚合酶(PARP)抑制剂的细胞毒性潜能,我们设计了一系列分子,这些分子包含与PARP靶向支架相连的1,2,3-三氮烯部分。基于细胞的选择性测定涉及BRCA2缺陷型中国仓鼠细胞系及其对应的BRCA2野生型转染子,用于预测后一种药物的PARP靶向潜力。结果表明,向PARP抑制剂中添加DNA破坏功能有所降低,但并未消除BRCA2缺陷型细胞的选择性靶向作用。DNA损伤部分增强了BRCA2的效力细胞缺陷减少2–20倍。发现最具选择性的双重PARP-DNA靶向剂14b具有双重DNA和PARP靶向特性。
