Cavitands formed with Cucurbit[6]uril have been described to host small molecules, transition metals and lanthanides, and intercalating Pt(II) complexes. Cucurbit[6]uril is also described to increase the cytotoxicity of some Pt(II)-based intercalators, and as Cucurbit[n]uril (n = 6, 7, 8) compounds were further shown to prevent metal complex degradation by glutathione, they have been indicated as potential drug delivery cavitands of interest. Cucurbit[6]uril has also been described to form highly symmetric columnar channels as hydrate crystals. A host molecule forming host-guest complexes
