    Snippet: Previous investigations revealed that CR and berberine have inhibitory effects against respiratory syncytial virus, influenza virus, enterovirus 71, herpes simplex virus, coronavirus and cytomegalovirus. In addition, studies showed that the inhibitory effects of berberine were mediated by downregulating cellular Not mentioned (Dhamgaye et al. 2014) c-Jun N-terminal protein kinase (JNK) and NF-kappa B activation (Hayashi et al. 2007 ), suppressing.....
    Document: Previous investigations revealed that CR and berberine have inhibitory effects against respiratory syncytial virus, influenza virus, enterovirus 71, herpes simplex virus, coronavirus and cytomegalovirus. In addition, studies showed that the inhibitory effects of berberine were mediated by downregulating cellular Not mentioned (Dhamgaye et al. 2014) c-Jun N-terminal protein kinase (JNK) and NF-kappa B activation (Hayashi et al. 2007 ), suppressing mitogen-activated protein kinase (MAPK) or MAPK/ERK kinase 1 (MEK)/extracellular signal-regulated kinase (ERK) signalling (Shin et al. 2015; Varghese et al. 2016) . Furthermore, berberine could suppress the EV71induced autophagy by activating the AKT protein and inhibiting the phosphorylation of JNK and phosphatidylinositol-4,5bisphosphate 3-kinase III (PI3KIII) (Wang HQ et al. 2017) . H1N1 infection could be also suppressed by a water extract of CR, during which the main alkaloids served as neuraminidase inhibitors, and among them, palmatine was the most effective, with an IC 50 of 50.5 mM ). The specific inhibition of West Nile virus (WNV) NS2B-NS3 protease and viral propagation by palmatine, with an IC 50 of 96 mM, was investigated. Palmatine was also effective against dengue virus and yellow fever virus (Jia et al. 2010) .
