    摘要: Methods of synthesizing a substantially monodispersed mixture of polymers comprising polyethylene glycol moieties include: reacting a substantially monodispersed mixture of compounds having the structure of Formula I: R1(OC2H4)b—O−X+  (I) wherein R1 is H or a lipophilic moiety; n is from 1 to 25; and X+ is a positive ion, with a substantially monodispersed mixture of compounds having the structure of Formula II: R2(OC2H4)m—OMs   (II) wherein R2 is H or a lipophilic moiety; and m is from 1 to 25, under conditions sufficient to provide a substantially monodispersed mixture of polymers comprising polyethylene glycol moieties and having the structure of Formula III: R2(OC2H4)m+n—OR1   (III). Substantially monodispersed mixtures of polymers comprising polyethylene glycol moieties are also disclosed.

    摘要: A system for selectively delivering drugs to target tissues is provided. The system includes a drug-linker-saccharide-drug conjugate (D-L-A-D1). The linker includes a functional group that is recognized and cleaved by enzyme in the target phases. The recognition segment is preferably a malaria drugs. The carrier is preferably hydrophilic, biodegradable and biocompatible particle. Any drug may be delivered using a conjugate prepared according to the invention.
