  • Patent number: 10960054
    Abstract: Disclosed herein includes a drug delivery system comprising at least one peptide and a targeting ligand for bone fracture and/or for bone healing. Some embodiments include a peptide delivery system comprising at least an acidic, basic, hydrophilic, hydrophobic or neutral peptide linked to an acidic peptide or nonpeptidic polyanion for use in targeting the aforementioned attached peptide to a bone fracture surface. In some embodiments, a conjugated peptide expresses an anabolic function that acts through PTH receptor 1, and various formats of targeting ligands guide the drug to raw hydroxyapatite.

  • Publication number: 20210000962
    Abstract: Aspects of the present disclosure generally relate to compounds for targeting and healing bone fractures. Some of these compounds include a negatively charged oligopeptide comprising an acidic oligopeptide, a linker, which may be hydrolyzable or may be a substrate for the protease cathepsin K, and at least one molecule that promotes bone healing. In some compounds the molecule that promotes bone healing is an anabolic compound that inhibits GSK3?, in some compounds the molecule that promotes the healing of bone fracture is a pro-inflammatory agent such as PGE1. Other embodiments include methods of treating a bone fracture comprising administering a therapeutic amount of any one of the compounds disclosed herein.
