Water-soluble polymeric bone-targeting drug delivery system

摘要

The present invention provides bone-targeting polymeric drug delivery systems based on HPMA and related copolymers and methods of making thereof. The water-soluble bone-targeting polymeric conjugates of the present invention comprise water-soluble copolymer backbones (P) which are linked, via a first spacer (S₁), with a bone-related therapeutic agents or drug (D) and, via a second spacer (S₂), with a bone-targeting moiety (T).
