describe the favorable properties of 6‐(N,N‐dimethyl‐2‐aminoethoxy)‐11‐(3,4,5‐trimethoxyphenyl)pyrido[3,4‐c][1,9]phenanthroline (P8‐D6), a powerful inducer of apoptosis caused by an equipotent inhibition of human topoisomerase I and II activities. A broad‐spectrum effect against human tumor cell lines at nanomolar concentrations, as well as strong antileukemic effects, were shown to be superior to those
经典的细胞毒性药物由于其有效性和对肿瘤耐药机制的更普遍的不敏感性,仍然是抗肿瘤治疗中必不可少的工具。在这里,我们描述了6-(N,N-二甲基-2-氨基乙氧基)-11-(3,4,5-三甲氧基苯基)吡啶[3,4- c] [1,9]菲咯啉(P8-D6),一种强大的凋亡诱导物,由人类拓扑异构酶I和II活性的均等抑制作用引起。在临床试验中,在纳摩尔浓度下对人类肿瘤细胞系的广谱作用以及强大的抗白血病作用被证明优于市售的靶向拓扑异构酶的药物和双重拓扑异构酶抑制剂。简便的四步合成法,有利的药物特性和初步的体内数据鼓励P8-D6在适当的动物肿瘤模型中应用以及进一步的药物开发。
