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.
