5′-Deoxy-6-thioguanosine, 2′,5′-dideoxy-6-thioguanosine, 5′-deoxy-6-mercaptopurine riboside and 2′,5′-dideoxy-6-mercaptopurine riboside were synthesized enzymatically from thiopurine bases and corresponding ribosyl donors using nucleoside phosphorylase. This is the first report of trans-5′-deoxyribosylation to thiopurine bases by nucleoside phosphorylase. 5′-Deoxy-6-thioguanosine selectively blocked
