A macromolecule includes i) a dendrimer with a core and at least one generation of lysine residue building units, the outermost generation of building units having surface amino groups, ii) a first terminal group covalently attached to a first surface amino group of a building unit, which includes a residue of docetaxel (DTX), and iii) a second terminal group covalently attached to a second surface amino group of a building unit, which includes a pharmacokinetic modifying agent. The pharmacokinetic modifying agent can be a polyethylene glycol (PEG). The first terminal group can be covalently attached to the surface amino group of the dendrimer through a diacid linker. The diacid linker can include a 2,2′-thiodiacetic acid residue. The diacid linker can form an ester bond with a hydroxyl group of the DTX and an amide bond with the surface amino group. A pharmaceutically acceptable salt of the macromolecule can be prepared.
一种大分子包括 i) 树枝状聚合物,具有核心和至少一代赖氨酸残基构建单元,最外层的构建单元具有表面氨基;ii) 与构建单元的第一表面氨基共价连接的第一末端基团,其中包括多西他赛(DTX)残基;iii) 与构建单元的第二表面氨基共价连接的第二末端基团,其中包括药代动力学修饰剂。药代动力学修饰剂可以是聚乙二醇(PEG)。第一末端基团可通过二酸连接剂共价连接到树枝状聚合物的表面氨基上。二酸连接体可包括 2,2′-硫代乙酸残基。二酸连接体可与 DTX 的羟基形成酯键,与表面氨基形成酰胺键。可以制备大分子的药学上可接受的盐。
