Fig. 5. In vitro inhibitory activity of mTG-23 against influenza A virus infection. (A) Light microscopy observation of a dose-dependent reduction in virus-induced cytopathic effect in the presence of mTG-23 in A549 cells after 48 hours of infection. A549 cells were infected with X31 (H3N2) influenza virus in the absence and presence of increasing concentrations of mTG-23. (B) Reduction in HA titer after 48 hours of infection in the presence of mTG-23. See the hemagglutination assay section for details. VC and CC are samples from virus control and cell control, respectively.
