Following our discovery of the potent anti-varicella zoster virus action of lipophilic alkyl furano pyrimidine 2′-deoxynucleosides, we now report that 2′,3′-dideoxy sugar analogues are devoid of anti-VZV activity but are potent and selective inhibitors of human cytomegalovirus (HCMV). The present compounds are active in vitro at ca. 1 μM with cytotoxicity only above 200 μM. Importantly, we have discovered that the new agents do not act as nucleoside analogues, despite their nucleosidic structure, and time of addition studies revealed that the compounds may inhibit HCMV at an event in the replication cycle of the virus that precedes DNA synthesis. They represent new leads in the discovery of improved therapies for HCMV, particularly in view of their novel mechanism of action.
