Seven dinuclear platinum(II) complexes with a novel chiral tetradentate ligand, (1R,1′R,2R,2′R)-N1,N1′-(1,4-phenylenebis(methylene))dicyclohexane-1,2-diamine, were designed, synthesized and spectrally characterized. All the complexes were evaluated for their in vitro cytotoxicity against human HepG-2, A549, HCT-116 and MCF-7 cancer cell lines. The results indicated that all compounds showed positive biological activity against HepG-2, A549 and HCT-116 cancer cell lines. In particular, compounds D7 and D2 showed better activity than carboplatin against HepG-2 and A549 and compound D7 also showed an activity close to that of oxaliplatin.

Platinum-based anticancer drugs have been becoming one of the most effective drugs for clinical treatment of malignant tumors for its unique mechanism of action and broad range of anticancer spectrum. But, there are still several problems such as side effects, drug resistance/cross resistance and no-specific targeting, becoming obstacles to restrict its expanding of clinical application. In recent years, supramolecular chemistry drug delivery systems have been gradually concerned for their favorable safety and low toxicity. Supramolecular macrocycles-platinum complexes increased the water solubility, stability and safety of traditional platinum drugs, and have become hot focus of developing novel platinum-based anticancer drugs because of its potential targeting of tumor tissues/organs. This article concentrates in the research progress of the new drug delivery system between platinum-based anticancer drugs with three generations of macrocycles: crown ether, cyclodextrin, cucurbituril and calixarene.
