In various aspects, embodiments of the present invention are directed to a series of multivalent dendrons containing a bioactive peptide domain and surface-binding catechol domains. In some embodiments, these multivalent dendrons were obtained through solid phase synthesis and have a strong binding affinity to metal oxide surfaces such as, TiO2, ZrO2, CeO2, and Fe3O4, SiO2, as well as other inorganic surfaces such as hydroxyapatite, silver, fluorapatite, calcium carbonate and gold. These catechol-bearing dendrons provide a fast and efficient method to functionalize a wide range of inorganic materials with bioactive peptides and have the potential to be used in coating orthopaedic implants and fixation devices.
在各个方面,本发明的实施例涉及一系列包含生物活性肽结构域和表面结合儿茶酚结构域的多价树状分子。在某些实施例中,这些多价树状分子是通过固相合成获得的,并且对金属氧化物表面(如TiO2、ZrO2、CeO2和Fe3O4、SiO2)以及其他无机表面(如羟基磷灰石、银、氟磷灰石、碳酸钙和金)具有很强的结合亲和力。这些含有儿茶酚的树状分子提供了一种快速高效的方法,可以将生物活性肽功能化到各种无机材料上,并有潜力用于包覆骨科植入物和固定装置。
