Abstract: The pseudorotaxane of cucurbituril(CB) with guest molecule 1,6-bis(imidazol-1-yl)hexane dihydrochloride(BIMH-Cl) made pBR322 DNA hydrolyzed efficiently in physiological environment. The cleavage mechanism was proposed that was a cooperation process of the CB molecule and the guest BIMH molecule. In this mechanism, the protonated imidazole might bind DNA via the electrostatic interactions and the CB glycoluril carbonyl oxygen atoms activated a water molecule to attack the phosphorus atom.

Key words: Cucurbituril, Pseudorotaxane, Crystal structure, DNA Cleavage
