Zanamivir 是一种高效、广谱的流感病毒神经氨酸酶 (NA) 抑制剂，对甲型流感和乙型流感的 IC50 值分别为 0.95 nM 和 2.7 nM。

Zanamivir is a hihly potent, broad-spetrum influenza viral neuraminidase (NA) inhibitor with IC50 of 0.95 nM and 2.7 nM for influenza A and B, respectively; inhibits plaque formation by laboratory-passaged strains of influenza A and B viruses,IC50 ranging from 0.005 to 0.014 uM; interacts with a group of amino acids in the active site of neuraminidase, which are conserved in all influenza A and B strains. Zanamivir blocks the action of neuraminidase, which prevents the cleavage of sialic acid on the cell receptors, thus preventing release and spread of the newly formed virions.Influenza Approved(In Vitro):Zanamivir interacts with a group of amino acids in the active site of neuraminidase, which are conserved in all influenza A and B strains. Zanamivir blocks the action of neuraminidase, which prevents the cleavage of sialic acid on the cell receptors, thus preventing release and spread of the newly formed virions.(In Vivo):Zanamivir has a poor bioavailability in oral administration, with only 4–17% of the agent. Oral delivery of zanamivir has been a problem due to its strong hydrophilic nature that limits its transport across the intestinal epithelium. Permeation enhancers such as sodium cholate, hydroxypropyl β-cyclodextrin could be used with zanamivir to enhance the intestinal permeability.
