The binding ability properties of two β-cyclodextrin dimers linked through their secondary faces by short, rigid spacer arms towards the cancer chemotherapeutic agent methotrexate were studied by ITC and NMR (1D and ROESY) experiments. Both dimers are able to bind two molecules of methotrexate with a binding constant between 2.4 and 3.5 times higher than that for native β-cyclodextrin, the dimer having the shortest linker forming the most stable complex.
