    • The present invention is directed to double prodrugs containing polymeric-based transport forms. These polymeric compounds comprise the formula: wherein: B is H, OH, OSiR13, a residue of an amine-containing target moiety or a residue of a hydroxyl-containing moiety; L1 and L2 are bifunctional linking moieties; Y2is O or S; R2 is selected from the group consisting of C1-6 alkyls, C3-12 branched alkyls, C3-8 cycloalkyls, C1-6 substituted alkyls, C3-8 substituted cycloalkyls, aryls, substituted aryls, aralkyls, C1-6 heteroalkyls, substituted C1-6 heteroalkyls, C1-6 alkoxy, phenoxy, and C1-6 heteroalkoxy; R9, R10, R13 are independently one of hydrogen, C1-6 alkyls, C3-12 branched alkyls, C3-8 cycloalkyls, C1-6 substituted alkyls, C3 S substituted cycloalkyls, aryls, substituted aryls, aralkyls, C1-6 heteroalkyls, substituted C1-6 heteroalkyls, C1-6 alkoxy, phenoxy, and C1-6 heteroalkoxy; Ar is a moiety which when included in Formula (I) forms a multi-substituted aromatic hydrocarbon or a multi-substituted heterocyclic group; (m) is zero or one; and R11 is a polymer residue. The first prodrug is generated when the polymeric portion of the double prodrug is cleaved and the parent molecule is generated rapidly thereafter in vivo, as a result of a trialkyl lock type lactonization-type reaction.
