We report the synthesis of a series of novel diphenylcarbazoles designed to interact with DNA. The compounds bearing two or three dimethylaminoalkyloxy side chains were found to bind much more tightly to DNA, preferentially at AT-rich sites, than the corresponding hydroxy compounds. The DNA binding compounds exhibit potent cytotoxic activity toward P388 leukemia cells. The 3,6-diphenylcarbazole thus represent an interesting scaffold to develop antitumor agents interacting with nucleic acids.
我们报道了一系列新型二苯基氮杂环的合成,这些化合物旨在与DNA相互作用。含有两个或三个二甲氨基烷氧基侧链的化合物被发现比相应的羟基化合物与DNA的结合更为紧密,尤其是在富含AT的位点。DNA结合化合物对P388白血病细胞表现出强效的细胞毒活性。因此,3,6-二苯基氮杂环代表了一种有趣的骨架,可用于开发与核酸相互作用的抗肿瘤药物。
