Nukleosider som förlorat två hydroxigrupper från sockerdelen. De flesta av dessa föreningar har bredspektrumverkan mot retrovirus tack vare sin antimetabola effekt. Nukleosiderna fosforyleras intracellulärt till 5'-trifosfat och hämmar omvänd transkription hos virus genom att bilda kedjeavslutningar.
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. The nucleosides are phosphorylated intracellularly to their 5'-triphosphates and act as chain-terminating inhibitors of viral reverse transcription.
