OSELTAMIVIR ACID Chemical Properties,Usage,Production

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.

Chemical Properties

White Solid

Uses

Oseltamivir Acid is a metabolite of Oseltamivir (O701000).

Uses

Oseltamivir Acid (Oseltamivir EP Impurity C) is a metabolite of Oseltamivir (O701000). It is a COVID19-related research product.

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.

in vivo

Oseltamivir acid (0.1, 1, or 10 mg/kg/day, twice daily by oral gavage) produces a dose-dependent antiviral effect against Vietnam/1203/04 (VN1203/04) virus. The 5-day regimen at 10 mg/kg/day protects 50% of mice; deaths in this treatment group are delayed and indicated the replication of residual virus after the completion of treatment. Dosages of 1 and 10 mg/kg/day significantly reduced virus titers in organs and provided 60% and 80% survival rates, respectively[5].
