Abstract

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.
