Abstract:Cyclodextrins form complexes with lanthanide ions in basic aqueous solutions. This complex formation in basic solution dramatically enhances the solubility of lanthanide ions, which are otherwise insoluble due to the formation of hydroxide gels. Solutions of the gamma-cyclodextrin-Ce3+ complex effectively hydrolyze 2prime-deoxyadenosine-5prime-monophosphate to 2prime-deoxyadenosine.
Keywords:Lanthanide ion  Pr3+ ion  cyclodextrin  DNA hydrolysis
