Patent ID: 7270808

Claim:
A compound represented by Formula I: wherein P represents a linear polymer chain; CD represents a cyclodextrin moiety; L 1 , L 2 and L 3 , independently for each occurrence, may be absent or represent a linker group; D, independently for each occurrence, represents a therapeutic agent or a prodrug thereof, T, independently for each occurrence, represents a targeting ligand or precursor thereof; a, m and v, independently for each occurrence, represent integers in the range of 1 to 10; n and w, independently for each occurrence, represent an integer in the range of 0 to about 30,000; and b represents an integer in the range of 1 to about 30,000; and wherein either P comprises cyclodextrin moieties in the polymer chain or n is at least 1, and wherein a plurality of therapeutic agents or prodrugs thereof are covalently attached to the polymer chain through attachments that are cleaved under biological conditions.
