The present disclosure relates to the delivery of multiple copies of a payload molecule such as an active agent or a chelating agent capable of capturing an active agent, using as a carrier for their delivery a biocompatible copolymer comprising side chain-linked amino acids functionalized at their alpha-amino group by a reactive azide moiety by means of which the payload molecules are coupled to the copolymer. The copolymer is typically further functionalized to contain a single copy of a cell type- or tissue type-specific targeting moiety.
本公开涉及使用
生物相容性共聚物作为载体,传递多个剂量分子副本,如活性剂或能够捕获活性剂的
螯合剂。这些共聚物包含通过其α-
氨基团上的反应性
叠氮基团功能化的侧链连接
氨基酸,通过这种方式,荷载分子与共聚物耦合。通常,这种共聚物进一步功能化,以包含细胞类型或组织类型特异性靶向基团的单个副本。
