  • 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).

  • Patent number: 11219692
    Abstract: The present invention provides amphiphilic telodendrimers that aggregate to form nanocarriers characterized by a hydrophobic core and a hydrophilic exterior. The nanocarrier core may include amphiphilic functionality such as cholic acid or cholic acid derivatives, and the exterior may include branched or linear poly(ethylene glycol) segments. Nanocarrier cargo such as hydrophobic drugs and other materials may be sequester in the core via non-covalent means or may be covalently bound to the telodendrimer building blocks. Telodendrimer structure may be tailored to alter loading properties, interactions with materials such as biological membranes, and other characteristics.
