A library of new aryl‐substituted naphthalene C8‐linked pyrrolo[2,1‐c][1,4]benzodiazepine (PBD) conjugates with various linker architectures were designed, synthesized, and evaluated for their anticancer activity against a panel of 11 human cancer cell lines. All 32 conjugates show anticancer potential, with some of them exhibiting particularly high activity (0.01–0.19 μM). Thermal denaturation studies
设计,合成并评估了具有各种接头结构的新型芳基取代萘C8连接的吡咯并[2,1– c ] [1,4]苯并二氮杂(PBD)共轭物对一组11人的抗癌活性癌细胞系。所有32个结合物显示出抗癌潜力,它们中的一些显示出特别高的活性(0.01-0.19μ中号)。热变性研究显示了相对于DC-81的有效DNA结合能力。在与细胞周期分布有关的生物学活性测定中,这些PBD结合物诱导G 0 / G 1阶段性停滞,也导致p53和caspase-9蛋白水平升高,随后凋亡的细胞死亡。特别地,一种缀合物是该系列中最有希望的候选物,有可能被单独或与现有抗癌疗法组合进行进一步研究。
