Many ruthenium(II) complexes show high antitumor activities, and the in vitro antitumor activities are usually related to DNA binding. We designed and synthesized two RuII polypyridyl complexes, [Ru(dmp)2(fpp)]2+ (dmp=2,9‐dimethyl‐1,10‐phenanthroline; fpp=2‐[3,4‐(difluoromethylenedioxy)phenyl]imidazo[4,5‐f] [1,10]phenanthroline and [Ru(phen)2(fpp)]2+ (phen=1,10‐phenanthroline). The DNA‐binding properties
许多钌(II)配合物显示出很高的抗肿瘤活性,体外抗肿瘤活性通常与DNA结合有关。我们设计并合成了两种 RuII 多吡啶配合物,[Ru(dmp)2(fpp)]2+ (dmp=2,9-二甲基-1,10-菲咯啉;fpp=2-[3,4-(二氟亚甲基二氧基)苯基]咪唑并[4,5-f] [1,10]菲咯啉和[Ru(phen)2(fpp)]2+ (phen=1,10-菲咯啉)。已经通过光谱研究了这些复合物的DNA结合特性滴定、DNA 熔解实验、粘度测量和光活化裂解。光裂解机理研究表明单线态氧 (1O2) 和超氧阴离子自由基 (O$\rm_2}^^\cdot} -}} }$) 可能在光裂解中起重要作用。复合物 1 和 2 的细胞毒性已通过 MTT (3-(4,5-二甲基噻唑-2-yl)-2, 5-二苯基-2H-溴化四唑)法;复合物 2 对所有筛选的细胞系显示出略高于 1 的抗癌效力。
