What is OSELTAMIVIR ACID?

Description

Oseltamivir (GS-4104) is an antiviral prodrug targeted against the influenza viruses. Oseltamivir acid is the active metabolite of oseltamivir. It acts as an inhibitor of influenza neuraminidases A and B (IC₅₀ = 0.1 to 4.9 nM for both enzymes), in this way preventing virus budding and release.

Definition

ChEBI: A cyclohexenecarboxylic acid that is cyclohex-1-ene-1-carboxylic acid which is substituted at positions 3, 4, and 5 by pentan-3-yloxy, acetamido, and amino groups, respectively (the 3R,4R,5S enantiomer). A antiviral drug, it is used as the corresponding ethyl ester prodrug, oseltamivir, to slow the spread of influenza.
