Polymer/Protein Supramolecular Systems Useful In Anticancer Drug Delivery

Supramolecular techniques have been adapted to obtain innovative bioconjugates to deliver drugs with poor biopharmaceutical properties [1]. Proteins, which are naturalheteropolymers, have evolved to exhibit a staggering array of functions and capabilities, are playing an increasing role as adrug carrier in the clinical setting for targeted delivery [2]. These carriers improve the pharmacokinetic profile of the drug or to target the drug to the pathogenic site addressing diseaseswith unmet medical needs. The application of proteins as nano-carriers for the design of efficient, multifunctional drugcarrier represents a newly emerging research area with a high commercial potential. Herein is described a new class of injectable andbioabsorbable supramolecular systems formed from polymer and protein for controlled drug delivery. This approache can improve the therapeutic efficacy and to reduce the side effects of drugs incorporated in delivery carriers
