AB 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 prepare purine 4'-thio
nucleosides. The compounds were tested against hepatitis B virus (HBV),
human cytomegalovirus (HCMV), herpes simplex virus (HSV-1 and HSV-2),
varicella zoster virus (VZV), and human immunodeficiency virus (HIV-1).
Cytotoxicity was determined in a number of cell lines. Several compounds
were extremely potent against HBV and HCMV and had moderate to severe
cytotoxicity in vitro. The lead compound from the series,
2-amino-6-(cyclopropylamino)purine 2'-deoxy-4'-thioriboside, was the
most potent and selective agent against HCMV and HBV replication in
vitro; however, this analogue was nephrotoxic when tested in vivo.
