Abstract: The present work revealed that the praseodymium(Ⅲ) complex of 2-carboxyethylgermanium sesquioxide(Ge-132) promotes the hydrolysis of the phosphodiester linkages of 3',5'-cyclic adenosine monophosphate(cAMP), 3',5'-cyclic deoxyadenosine monophosphate(dcAMP), 5'-adenosine monophosphate(5'-AMP), 5'-deoxyadenosine monophosphate(5'-dAMP) under mild conditions. Both cAMP, dcAMP were hydrolyzed sitespecifically, yielding predominantly 3'-monophosphates, the main products of the cleavage of 5'-AMP, 5'-dAMP included adenosine(Ado), deoxyadenosine(dAdo), free phosphates respectively. A hydrolytic mechanism was proposed for cAMP, dcAMP, 5'-AMP, 5'-dAMP.
