Research Abstract

In the development of drug nanocarriers in drug delivery systems or recombinant protein medicines, rapid blood clearance of these is frequently problematic. To overcome this rapid clearance, we attemped to obtain petides having long circulating characteristic by use of phage-displayed peptide library that presenting 5 mer random peptides. After intravenous injection of the library, we selected long circulating phages and identified long circulating peptides. Unfortunately, the circulating characteristics of drug nanocarriers was not improved by modifying the surface of them with the peptides. However, since cloned phages presenting these peptids showed quite long circulation in the bloodsteam of mice, we believe that these peptides are useful for the development of DDS drugs or protein drugs.
