摘要: The present invention concerns fusion of Fc domains with biologically active peptides and a process for preparing pharmaceutical agents using biologically active peptides. In this invention, pharmacologically active compounds are prepared by selecting a peptide that modulates the activity of a protein of interest and preparing a pharmacologic agent having an Fc domain covalently linked to the peptide. Linkage to the Fc domain increases the half-life of the peptide, which otherwise would be quickly degraded in vivo. The peptide can be selected, for example, by phage display, E. coli display, ribosome display, RNA-peptide screening, yeast-based screening, chemical-peptide screening, rational design, or protein structural analysis.

摘要: The present invention concerns fusion of Fc domains with Ang-2 binding peptides and a process for preparing such molecules. In this invention, pharmacologically active compounds are prepared by a process comprising (a) selecting at least one random peptide that binds to Ang-2; and (b) preparing a pharmacologic agent comprising an Fc domain covalently linked to at least one amino acid of the selected peptide. Linkage to the vehicle increases the half-life of the peptide, which otherwise would be quickly degraded in vivo. The preferred vehicle is an Fc domain. The peptide can be selected, for example, by phage display, E. coli display, ribosome display, RNA-peptide screening, yeast-based screening, chemical-peptide screening, rational design, or protein structural analysis.
