Based on the synthesis of curcumin and its derivatives from aromatic aldehydes, a novel series of palladium(II) complexes with curcumin (or its derivatives) and 2,2′-bipyridine have been synthesized through a directed self-assembly approach that involves spontaneous deprotonation of the curcuminoid ligands in H2O/acetone solution. These complexes have been characterized by 1H (13C) NMR, HRMS and elemental
基于从芳香醛合成姜黄素及其衍生物,通过涉及自发去质子化的定向自组装方法,合成了一系列新的钯(II)与姜黄素(或其衍生物)和2,2'-联吡啶的配合物H 2 O /丙酮溶液中的姜黄素配体的制备 这些配合物已通过1 H(13 C)NMR,HRMS和元素分析进行了表征。通过X射线衍射分析确定了3h的晶体结构。通过MTT测试它们的细胞毒性。初步结果表明,配合物3d,3f,3h对三种癌细胞(如MCF-7,HeLa和A549细胞)的增殖具有明显的抑制作用,它们的活性比顺铂高。进一步的机理研究表明,受试复合物3h使细胞周期停滞在S期,并可以通过依赖于活性氧(ROS)的途径破坏线粒体膜电位并诱导肿瘤细胞凋亡。
