摘要
To provide peptides having high affinity for hemagglutinin and peptides having high inhibitory activity against influenza virus infection, as well as pharmaceutical compositions containing the peptides, the polypeptides having any one of SEQ ID NOs: 2 to 7, 9 to 10, and 12 to 18 are obtained by introducing mutation into a peptide having the sequence of ARLSPTMVHPNGAQP (peptide A-1: SEQ ID NO: 1) and screening for peptides having higher affinity for hemagglutinin. Further, the inhibitory activity of the peptide of SEQ ID NO: 3 against influenza virus infection can be enhanced by truncating SEQ ID NO: 3 in its C-terminus region with leaving ARLPR or ARLP. In addition, an influenza virus-infection inhibitor and an influenza preventive/therapeutic agent can be prepared by formulating these influenza virus receptor-binding peptides.
