Oseltamivir is an antiviral for systemic use, a neuraminidase inhibitor.It is administrated as a phosphate derivate that is a prodrug of the active metabolite (oseltamivir carboxylate). The active metabolite is a selective inhibitor of influenza virus neuraminidase enzymes, which are virion surface glycoproteins.
The functional groups of oseltamivir is a cyclohexene which is composed of four ramifications:
*Ethyl Methanoate (Ethyl Formate), which will be converted to a methanoate.
*Amino group.
*Acetamido group (Acetyl + amine).
*And an ether pentane.
Shikimic acid is the basis (precursor) of the manufacture of oseltamivir (Tamiflu), one of the best non-vaccine influenza chemotherapy.
Its functional groups are:
*Three hydroxyl group that will be replaced by an ether group, acetamido group, an amino group to form oseltamivir.
*A carboxylic group which will be transformed into an ester group to form oseltamivir.
