Described herein are biodegradable drug delivery conjugates for effectively delivering bioactive agents to a subject. The drug delivery conjugates comprise a water-soluble high molecular weight linear biodegradable polymer backbone comprising a plurality of linear water-soluble polymeric segments connected to one another by a first (main-chain) cleavable linker, wherein a bioactive agent is covalently bonded to at least one water-soluble polymeric segment, at least one cleavable linker, or a combination thereof. The conjugates possess numerous advantages over prior art delivery conjugates. Also described herein are methods for making and using the conjugates.
本文描述了一种可生物降解的药物传递共轭物,用于有效地将生物活性物质传递给受试者。药物传递共轭物包括水溶性高分子量线性可生物降解聚合物骨架,该骨架包括通过第一(主链)可断裂连接剂相互连接的多个线性水溶性聚合物段,其中生物活性物质与至少一个水溶性聚合物段,至少一个可断裂连接剂或其组合共价键合。与先前的传递共轭物相比,这些共轭物具有许多优点。本文还描述了制备和使用这些共轭物的方法。
