  • Publication number: 20110245458
    Abstract: Disclosed is a peptide nucleic acid monomer as well as a corresponding peptide nucleic acid molecule. The monomer comprises a terminal amino group and a terminal group A. The terminal amino group and the terminal group A are connected by an aliphatic moiety. The main chain of this aliphatic moiety is free of groups that are charged under physiological conditions. The terminal group A is one of —COOH, —COOR3, —COX, —COSR3, —CN, —CONH2, —CONHR3, —CONR3, R4, with R3 and R4 being H or an aliphatic, alicyclic, aromatic, arylaliphatic or arylalicyclic group, and X being a halogen atom. The terminal amino group is substituted by an aliphatic group with a main chain of at least two carbon atoms and optionally 0 to a bout 2 heteroatoms selected from the group N, O, S, Se and Si. The main chain has a polar head group Z.

  • Patent number: 7488590
    Abstract: Pharmacologically active compounds are prepared by (a) selecting at least one peptide that modulates the activity of AGP-3, (b) preparing a gene construct that comprises at least one said selected sequence, and (c) expressing the pharmacologically active compound in which an Fc domain is covalently linked to the selected peptide. The pharmacologic agent can be expressed in E. coli.

  • Publication number: 20070049532
    Abstract: 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.

  • Publication number: 20060234307
    Abstract: 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.
