Abstract
Wogonin, a flavonoid isolated from Scutellaria baicalensis, has attracted increasing scientific attention in recent years because of its potent anti-tumor activity. Its role during viral infection has largely been unexplored. Wogonin treatment effectively suppressed both influenza A and B virus replication in Madin-Darby Canine Kidney (MDCK) cells and human lung epithelial (A549) cells. In contrast, wogonin treatment following influenza A virus infection led to up-regulation of interferon (IFN)-induced antiviral signaling. Additionally, influenza A virus infection in A549 cells induced 5' adenosine monophosphate-activated protein kinase (AMPK) phosphorylation and activation in a time-dependent manner and wogonin treatment led to the suppression of AMPK phosphorylation. Furthermore, the treatment with AMPK-specific inhibitor (compound C; CC) attenuated influenza A virus replication. These data suggest that wogonin possesses a potent anti-influenza activity mediated by regulation of AMPK activation, suggesting that wogonin has the potential to be developed as an anti-influenza drug.
