Background: Purine nucleoside phosphorylase (PNP) from Escherichia coli is a hexameric enzyme that catalyzes the reversible phosphorolysis of 6-amino and 6-oxopurine (2′-deoxy)ribonucleosides to the free base and (2′-deoxy)ribose-1-phosphate. In

A series of 2'-deoxy-4'-thioribo purine nucleosides was prepared by trans-N-deoxyribosylase-catalyzed reaction of 2'-deoxy-4'-thiouridine with a variety of purine bases. This synthetic procedure is an improvement over methods previously used to prepa

A series of α-L-2′,3′-dideoxy nucleosides was prepared as potential antiviral agents. The pyrimidine nucleosides were prepared by standard Vorbruggen coupling reactions. The purine analogues were prepared by enzymatic transfer of the dideoxy sug
