  • Publication number: 20120309694
    Abstract: The invention provides synthetic heparin-binding growth factor analogs having two peptide chains each branched from a branch moiety, such as trifunctional amino acid residues, the branch moieties separated by a first linker of from 3 to about 20 backbone atoms, which peptide chains bind a heparin-binding growth factor receptor and are covalently bound to a non-signaling peptide that includes a heparin-binding domain, preferably by a second linker, which may be a hydrophobic second linker. The synthetic heparin-binding growth factor analogs are useful as pharmaceutical agents, soluble biologics or as surface coatings for medical devices.

  • Patent number: 8101570
    Abstract: A heparin-binding growth factor (HBGF) analog having two substantially similar sequences (homodimeric sequences) branched from a single amino acid residue, where the sequences are analogs of a particular HBGF that binds to a heparin-binding growth factor receptor (HBGFR), or alternatively that bind to a HBGFR without being an analog of any particular HBGF. The homodimeric sequences may be derived from any portion of a HBGF. The synthetic HBGF analog may be an analog of a hormone, a cytokine, a lymphokine, a chemokine or an interleukin, and may bind to any HBGFR. Further provided are preparations for medical devices, pharmaceutical compositions and methods of using the same.
