Zanamivir 生物活性

描述 Zanamivir is a potent competitive inhibitor of viral neuraminidase, and inhibits a wide range of influenza A and B types in vitro . The drug is selective for the viral form of the neuraminidase enzyme and does not interact to any significant extent with its human lysosomal equivalent[3]. In Madin-Darby canine kidney (MDCK) cell cultures, IC50 values for zanamivir (i.e. the drug concentration required to inhibit plaque formation of influenza A and B viruses by 50%) in laboratory passaged isolates (0.004 to 0.014 μmol/L) and clinical isolates (0.002 to 16 μmol/L) were largely lower than values for amantadine >25 μmol/L), rimantadine (<0.27 to >25 μmol/L) and ribavirin (6.1 to 54 μmol/L)[4]. Zanamivir was also effective in the inhibition of influenza A [A/Virginia/88 (H3N2) and A/Texas/36/91 (H1N1)] and B (B/Hong Kong/5/72) strains in yield reduction assays in human respiratory epithelium, with concentrations required for 90% inhibition of viral replication (IC90) of <0.03 and 0.75 μmol/L, respectively[5]. In MDCK cell cultures,IC50 values for zanamivir ranged from <0.01 to >100 μmol/L and <0.01 to 21 μmol/L against influenza A strains, from 0.03 to 1.3 μmol/L against influenza B strains[6]. Intranasal zanamivir was 100 to 1000 times more active against influenza A [A/Singapore/1/57(H2N2) and A/Mississippi/1/85 (H3N3)] and B(B/Victoria/102/85) than were amantadine and ribavirin in animal studies. In addition, delayed administration of the drug (for up to 22 hours postinfection) reduced viral replication in ferrets[5].
