A variety of novel aromatic and heterocyclicaromatic curcuminoids were synthesised, characterised and their anti-inflammatory activities (AIA) determined in vivo. Some of these compounds also were tested for inflammatory mediator production. The AIA of the main representatives of these compounds were assessed by oral administration to female Wistar rats using (a) acute carrageenan-induced paw oedema
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。
