(Science: chemical) Nucleosides that have two hydroxy groups removed from the sugar moiety. The majority of these compounds have broad-spectrum antiretroviral activity due to their action as antimetabolites.

Pharmacological action: antimetabolites, antiviral agents, reverse transcriptase inhibitors.
