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.

摘要:
Methods of treating diabetes mellitus in a patient in need of such treatment include administering an effective amount of an insulin drug to the patient in order to treat diabetes mellitus in the patient. Methods according to the present invention may “activate” the liver, potentially restoring normal glucose homeostasis to individuals suffering from diabetes mellitus.
摘要:
A mixture of conjugates in which each conjugate in the mixture comprises an insulin drug coupled to an oligomer that includes a polyalkylene glycol moiety is disclosed. The mixture may exhibit higher in vivo activity than a polydispersed mixture of similar conjugates. The mixture may also be more effective at surviving an in vitro model of intestinal digestion than polydispersed mixtures of similar conjugates. The mixture may also result in less inter-subject variability than polydispersed mixtures of similar conjugates.
