Description

S119-8 is a broad spectrum inhibitor of influenza A and B viruses, showing activity against multiple influenza B viruses and an oseltamivir-resistant influenza A virus, but does not inhibit a non-influenza virus, vesicular stomatitis nirus (VSV)[1].

IC50 & Target

Influenza A and B[1]
In Vitro

S119-8 is an analog of S119. S119-8 has acquired enhanced broad-spectrum activity with improved calculated physical properties, while maintaining significant potency (IC50=1.43 μM) at non-toxic (CC50=66.10 μM) concentrations, albeit somewhat higher (7-fold) than that of the parent S119 against influenza A/WSN/33 H1N1 (WSN) virus. S119-8 also shows activity against multiple influenza B viruses and an oseltamivir-resistant influenza A virus, but does not inhibit a non-influenza virus, vesicular stomatitis nirus (VSV). S119-8 has increased breadth of inhibition against influenza A and B viruses accompanied by only a small loss in potency. S119-8 inhibits influenza viruses A/Puerto Rico/8/1934 (H1N1) (PR8) with an IC50 of 6.05 μM. S119-8 inhibits influenza A/Vietnam/1203/2004 (H5N1) with an IC50 of 8.42 μM[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
