Abstract
Berbamine (BBM) is a bibenzyl isoquinoline present in the traditional Chinese herbal medicine Berberis amurensisis Rupr. The present study demonstrates that BBM exerts strong antiviral efficacy against influenza A virus (IAV) infection. We examined the anti-IAV effect of BBM using green fluorescent protein (GFP)-expressing influenza A and H1N1 IAV. The fluorescence microscopy, fluorescence-activated cell sorting analysis, and plaque assay showed that BBM significantly hinders IAV infection. The immunofluorescence analysis confirmed the anti-influenza activity of BBM. From the time-of-addition and hemagglutination inhibition results, it is elucidated that the antiviral effect of BBM is closely related to its inhibitory effect against viral binding and entry at an early infection stage. Our findings imply that BBM has the potential to be developed as a potent antiviral drug against influenza viral infection.
期刊介绍：
The International Journal of Molecular Sciences (ISSN 1422-0067) provides an advanced forum for chemistry, molecular physics (chemical physics and physical chemistry) and molecular biology. It publishes research articles, reviews, communications and short notes. Our aim is to encourage scientists to publish their theoretical and experimental results in as much detail as possible. Therefore, there is no restriction on the length of the papers or the number of electronics supplementary files. For articles with computational results, the full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material (including animated pictures, videos, interactive Excel sheets, software executables and others).
