Hydrolytic decomposition of four 5-azacytosine acyclic nucleoside phosphonates was studied. Products of the decomposition are carbamoylguanidine derivatives. Stability and decomposition products of HPMP-5-azaC (a 5-azacytosine derivative with strong antiviral activity) differ from the other derivatives. The reaction pathway of HPMP-5-azaC involves a formyl derivative formed by intramolecular transformylation reaction. (c) 2008 Elsevier Ltd. All rights reserved.
