Cyclodextrin functionalized polymers as drug delivery systems

Abstract

Cyclodextrins belong to the most important and promising macrocyclic hosts, since they are inexpensive, water-soluble natural products, non-toxic, readily functionalized and commercially available. Cyclodextrin chemistry creates lots of research areas. The present review focuses on investigations of cyclodextrins in polymer chemistry and their applications in drug delivery systems. Click reactions as a possibility to obtain polymer chains with covalently attached cyclodextrins are described, and examples for the application of such polymers in drug delivery are shown.
