QUICK LINKS

This compound falls under the category of triazole ribonucleosides and ribonucleotides, which are nucleoside derivatives featuring a ribose (or deoxyribose) unit glycosylated to a triazole. Nucleotides, on the other hand, possess a phosphate group connected to the C5 carbon of the ribose (or deoxyribose) moiety. Levovirin, a monocyclic L-nucleoside, possesses type 1 cytokine-inducing properties. It is the L-enantiomer of Ribavirin, exhibiting comparable immunomodulatory effects, yet lacking direct antiviral activity or causing hemolytic anemia.
