Cancer is one of the main causes of death worldwide. Chemotherapy, despite its severe sides effect, is to date one of the leading strategies against cancer. Metal-based drugs present several potential advantages when compared to organic ones and gained trust from the scientific community after the approval on the market of the drug cisplatin. Recently, we reported a ruthenium complex ( [Ru(DIP) 2 (sq)](PF 6 ) where DIP is 4,7-diphenyl-1,10-phenantroline and sq is the semiquinonate), with a remarkable potential as chemotherapeutic agent against cancer, both in vitro and in vivo . In this work, we analyse a structurally similar compound, namely [Ru(DIP) 2 (mal)](PF 6 ) , carrying the flavour-enhancing agent approved by the FDA, maltol (mal). To possess an FDA approved ligand is crucial for a complex, whose mechanism of action might include ligand exchange. Herein, we describe the synthesis and characterisation of [Ru(DIP) 2 (mal)](PF 6 ) , its stability in solutions and in conditions which resemble the physiological ones, and its in-depth biological investigation. Cytotoxicity tests on different cell lines in 2D model and on HeLa MultiCellular Tumour Spheroids (MCTS) demonstrated that our compound has higher activity compared to the approved drug cisplatin, inspiring further tests. [Ru(DIP) 2 (mal)](PF 6 ) was efficiently internalised by HeLa cells through a passive transport mechanism and severely affected the mitochondrial metabolism.

含麦芽酚的钌多吡啶基复合物,作为潜在的抗癌剂。

癌症是全世界主要的死亡原因之一。尽管有严重的副作用,化学疗法仍是迄今为止抗癌的主要策略之一。金属基药物与有机基药物相比具有几个潜在的优势,并且在顺铂市场上获得批准后获得了科学界的信任。最近,我们报道了一种钌络合物([Ru(DIP)2(sq)](PF 6,其中DIP为4,7-二苯基-1,10-菲咯啉,sq为半奎宁酸盐),具有显着的化学治疗潜力在体外和体内抗癌。在这项工作中,我们分析了结构相似的化合物,即[Ru(DIP)2(mal)](PF 6),该化合物带有FDA批准的增味剂麦芽酚(mal)。拥有FDA批准的配体对于复合物至关重要,其作用机理可能包括配体交换。在这里,我们描述[Ru(DIP)2(mal)](PF 6)的合成和表征,其在溶液和类似于生理条件的条件下的稳定性,以及深入的生物学研究。在2D模型中的不同细胞系和HeLa多细胞肿瘤球体(MCTS)上的细胞毒性测试表明,与批准的顺铂药物相比,我们的化合物具有更高的活性,从而激发了进一步的测试方法。[Ru(DIP)2(mal)](PF 6)被HeLa细胞通过被动转运机制有效内在化,并严重影响线粒体的代谢。及其深入的生物学研究。在2D模型中的不同细胞系和HeLa多细胞肿瘤球体(MCTS)上的细胞毒性测试表明,与批准的顺铂药物相比,我们的化合物具有更高的活性,从而激发了进一步的测试方法。[Ru(DIP)2(mal)](PF 6)被HeLa细胞通过被动转运机制有效内在化,并严重影响线粒体的代谢。及其深入的生物学研究。在2D模型中的不同细胞系和HeLa多细胞肿瘤球体(MCTS)上的细胞毒性测试表明,与批准的顺铂药物相比,我们的化合物具有更高的活性,从而激发了进一步的测试方法。[Ru(DIP)2(mal)](PF 6)被HeLa细胞通过被动转运机制有效内在化,并严重影响线粒体的代谢。
