Abstract
The present invention relates to viral peptides referred to as "DP107- and DP178-like" peptides. Specifically, the invention relates to isolated influenza A DP107- and DP178-like peptides which are identified by sequence search motif algorithms. The peptides of the invention exhibit antiviral activity believed to result from inhibition of viral induced fusogenic events.
Claims5
An isolated peptide region of an influenza A virus protein, said region comprising an amino acid sequence identified by an ALLMOT15, 107.times.178.times.4, or PLZIP sequence search motif.
An isolated peptide of the formula
- X-QAAIDQINGKLNRVIEKTNEKFHQIEKEFSEVEGRIQDLEKYVEDTKIDLWSYNAELLVALENQHTI-Z (SEQ ID NO. 210);
- or
- X-AADLKSTQAAIDQINGKLNRVIEKTNEKFHQIEKEFSEVEGRIQDLEKYVEDTKIDLWSYNAELLVALENQHT IDLT-Z (SEQ ID NO. 211),
- in which:
- X comprises an amino group, an acetyl group, a 9-fluoroenylmethoxy-carbonyl group, a hydrophobic group, or a macromolecular carrier group;
- and
- Z comprises a carboxyl group, an amido group, a hydrophobic group, or a macromolecular carrier group.
