  • Publication number: 20230346960
    Abstract: The present disclosure provides pro-angiogenic proteoglycan mimetics that can provide a provisional, pro-angiogenic scaffold to support tissue regeneration while limiting systemic exposure to VEGF activity. These mimetics can protect a collagen matrix from rapid degradation, and in conjunction with EPCs promote angiogenesis in order to accelerate ischemic wound healing. For example, the provided compounds can be delivered from the end of a catheter following balloon angioplasty to coat the collagen exposed areas, prevent platelet binding and thrombosis, support capture of EPCs from blood to facilitate reendothelialization, and reduce late-lumen loss (neointimal hyperplasia).

  • Publication number: 20220241227
    Abstract: The present invention provides compositions and methods comprising conjugates with a polymeric backbone, e.g., polyvinyl alcohol (PVA), covalently linked histone deacetylase (HDAC) inhibitors, such as butyrate or propionate, and covalently linked retinoids, such as all-trans retinoic acid (RA). The methods and compositions of the invention are useful for the treatment or prevention of cancer or metabolic diseases in tissues such as the colon or liver.

  • Publication number: 20210401993
    Abstract: The present invention provides methods of treating a subject having a primary inflammatory disease or disorder comprising administering to the subject a composition comprising a conjugate of an LLP2A peptidomimetic ligand and a bisphosphonate drug, wherein the composition comprising the LLP2A-bisphosphonate conjugate enhances the delivery of mesenchymal stem cells to a site of inflammation. Methods of enhancing an anti-inflammatory or immunomodulatory property of mesenchymal stem cells, comprising administering to a subject in need thereof the mesenchymal stem cells and a composition comprising a conjugate of an LLP2A peptidomimetic ligand and a bisphosphonate drug, are also provided.
