New metallocene-bridged cyclodextrin dimer: A stable derivative of the antitumor drug titanocene dichloride and its potent cytotoxity against human breast cancer (MCF-7) cells

A novel cyclodextrin dimer bridged with titanocene moiety, titanocene di[mono[6-deoxy-6-(2-(thio-1,2-dicyane ethylenylthio)ethyl thio-1,2-dicyane ethylenylthio)]-β-cyclodextrin] (6), has been synthesized and characterized by IR spectroscopy, UV spectroscopy, thermogravimetry, MALDI-TOF MS spectrum, 1H and 13C NMR spectroscopy. Especially, its potent cytotoxity against Human Breast Cancer (MCF-7) has also been studied.

A novel cyclodextrin dimer bridged with titanocene moiety has been synthesized and characterized. The introduction of the cyclodextrin into the titanocene compound remarkably increased its soluble and stable ability in water and the new compound demonstrated much higher cytotoxity against human breast cancer cells than titanocene dichloride.Figure optionsDownload as PowerPoint slide
