Mechanism  CP3, a cyclic peptide inhibitor, can inhibit Ebola virus budding by preventing the binding of UEV domain proteins to the P6 motif. CP3 forms hydrogen bonds with UEV domain proteins through its Tyr147 and Trp148 residues. Additionally, its Trp145, Tyr147, Ile146, and Trp148 residues engage in nonbonding interactions with UEV domain proteins. These interactions suggest that CP3 effectively disrupts the protein-protein interactions essential for the budding of both Ebola viruses.
