Pseudorabies (PR) is an acute infectious disease caused by pseudorabies virus (PRV). There are no available drugs due to the emergence of variant of PRV. Dihydromyricetin (DMY) is a flavonoid extracted from Ampelopsis grossedentata (A. grossedentata), which has a variety of pharmacological activities. In this study, we aim to investigate the in vitro anti-PRV activity of DMY extracted from A. grossedentata. MTT assay was used to detect the cytotoxicity and antiviral activity of DMY. The results

This suggested that anti-pyroptosis may be an important antiviral mechanism for DMY which is expected to be a potential anti-PRV drug.
