Preparation and properties of N6-monobutyryl adenosine 5'-monophosphate. A major hepatic metabolite of N6,O2'-dibutyryl cyclic adenosine 3':5'-monophosphate.

The synthesis and properties of N6-monobutyryl adenosine 5'-monophosphate are described. The properties of synthesized monobutyryl nucleotide have been compared to those of a metabolite recognized in previous studies (Castagna, M. C., Palmer, W.K., and Walsh, D.A. (1977) Arch. Biochem. Biophys. 181, 46-60) as the major radioactive product produced in the liver upon perfusion with N6,O2'-dibutyryl cyclic [3H]adenosine 3':5'-monophosphate. By the criteria of cochromatography on DEAE-cellulose and in three thin layer chromatographic systems and from equivalent rates of alkaline hydrolysis, N6-monobutyryl adenosine 5'-monophosphate has been identified as a major hepatic metabolite of N6,O2'-dibutyryl cyclic adenosine 3':5'-monophosphate.
