Considering that the inhibitory dose of teicoplanin on the activity of cathepsin L is higher than that required for Ebola virus infection inhibition, a cell viability assay was performed to confirm that the inhibitory effect is not due to cytotoxicity (Fig. 6C) . Ebola trVLP system (28) , which can simulate the life cycle of wild-type Ebola viruses to a large extent, was applied to investigate whether teicoplanin and its glycopeptide antibiotic homologs dalbavancin, oritavancin, telavancin, and vancomycin can also inhibit the entry of Ebola trVLPs. Accordingly, the p4cis plasmid encoding Renilla luciferase, VP40, GP, and VP24 was transfected into HEK293T cells along with plasmids expressing T7 RNA polymerase, NP, VP35, VP30, and L viral proteins to produce Ebola trVLPs (Fig. 7A) . ./cache/cord-353012-rxhi8wd2.txt ./txt/cord-353012-rxhi8wd2.txt
