摘要: The present invention relates to novel compositions comprising polymeric moieties covalently attached therapeutic agents, wherein the agent is moiety through a tether. By selecting from variety of tether groups and targeting ligands polymers methods for controlled delivery agents. also treating subjects with described herein. comprises self-cyclizing moiety, such as -S-CH2-CH2- CO-, -NR-CH2-CH2-NR-CO- -S-CH2-CH2-NR-CO-. drug conjugates cyclodextrin-based polymers.
