Zanamivir (GG167) is a guanido-neuraminic acid that is used to inhibit NEURAMINIDASE.

Zanamivir hydrate is neuraminidase inhibitors. It is used worldwide for the treatment and prophylaxis of influenza caused by influenza A and B viruses.

Zanamivir-13C,15N2 is intended for use as an internal standard for the quantification of zanamivir by GC- or LC-MS. Zanamivir (T2529) is a sialic acid analog that inhibits neuraminidase release of newly replicated influenza virus particles.1It has been shown to selectively inhibit the growth of influenza A and B viruses in plaque reduction assays with IC50values ranging from 5 to 14 nM and to directly inhibit influenza A and B virus neuraminidases with IC50values ranging from 0.6 to 7.9 nMin vitro. Intranasal zanamivir administration at 0.4 mg/kg twice daily reduces mortality and viral titers in lung homogenates of mice infected with influenza.
