A graft copolymer having drug-containing side chains is described. The graft copolymer can be prepared, for example, by directly polymerizing a drug- containing monomer on multiple sites of a linear copolymer. When exposed to water, the graft copolymer can form uniform nanocarriers, e.g., nanomicelles, optionally encapsulating additional drugs, e.g., non-covalently in the interior of the nanocarriers, for coordinated drug delivery of a plurality of drugs. Also described herein is the use of the nanocarriers for delivery of therapeutic agents, particularly the dual delivery of chemotherapeutic agents to treat tumors.
一种具有含药侧链的嫁接共聚物被描述。该嫁接共聚物可以通过在线性共聚物的多个位点上直接聚合含药单体来制备。当暴露在
水中时,该嫁接共聚物可以形成均匀的纳米载体,例如纳米胶束,可选择地在纳米载体的内部非共价地封装额外的药物,以协调输送多种药物的药物传递。本文还描述了利用这些纳米载体输送治疗剂,特别是双重输送化疗剂以治疗肿瘤。
