Multi-nuclear platinum complexes encapsulated in cucurbit[n]uril as an approach to reduce toxicity in cancer treatment

The dinuclear platinum complex trans-[{Pt(NH3)(2)Cl}(2)mudpzm](2+) (di-Pt) binds inside cucurbit[7]uril with slow exchange kinetics which does not significantly affect the cytotoxicity of the dinuclear complex but reactivity at the platinum centre is reduced.
