Abstract: Viral infection has become one of the worst human lethal diseases. In recent years,
major gains have been made in the research of peptide-based antiviral agents on account of the
mechanism of viral membrane fusion, among which the peptide Enfuvirtide has been listed for the
treatment of AIDS. This paper reviewed a new way to design peptide-based antiviral agents by
"bundling" superhelix with isopeptide bonds to construct the active advanced structure. It can
solve the problem that peptide precursor compounds derived from the natural sequence of viral
envelope protein tend to aggregate and precipitate under physiological conditions and low activity
and endow the peptide agents with the feature of thermal stability, protease stability and in vitro
metabolic stability. This approach is also providing a new way of thinking for the research and
development of broad-spectrum peptide-based antiviral agents.
