The extract of Elaeocarpus sylvestris inhibits human cytomegalovirus immediate early gene expression and replication in vitro

초록

Human cytomegalovirus (HCMV) is a major cause of morbidity and mortality in newborn infants, immunocompromised individuals with HIV/AIDS and organ transplant recipients. In order to identify a novel antiviral candidate for HCMV-related diseases, crude ethanol extracts from plants were screened for their potential inhibitory activity on HCMV replication in vitro. Ethanol (70%) extract of Elaeocarpus sylvestris leaves (ESE) markedly inhibited the replication of the HCMV Towne strain without exhibiting any significant adverse effects on the viability of human foreskin fibroblasts (HFF). In addition, ESE significantly downregulated HCMV immediate early (IE) gene expression. Taken together, this is the first study, to the best of our knowledge, demonstrating that ESE has a potent antiviral activity against HCMV by downregulating HCMV IE gene expression and replication.
