Abstract: Disclosed are nanoparticles for the delivery of a therapeutic agent or a diagnostic agent to a subject that include a chitosan and a polyphosphate, wherein the weight ratio of the chitosan to the polyphosphate is about 1.0 or greater and the weight ratio of the polyphosphate to the therapeutic agent or diagnostic agent is about 15.0 or less. Also disclosed are nanoparticles that include a chitosan and an inhibitor of enhancer of Zeste homologue 2 (EZH2). Methods of delivering a therapeutic agent or a diagnostic agent to a subject for the treatment or prevention of a disease and methods of predicting prognosis of ovarian cancer in a subject that involve determining the expression and/or function of EZH2 in the subject are also disclosed.

Abstract: This application describes a novel technology in drug discovery and drug-based imaging/detection: the wrapping technology. This technology is based on identified singularities in the structure of soluble proteins. In contrast with drug-design approaches based on standard structural considerations, the packing of a protein, or more precisely, its dehydron pattern, may be used as a selectivity filter to design small-molecule inhibitors. The wrapping technology described herein is a novel form of rational drug design for avoiding side effects in drug therapy and sharpening the inhibitory impact of drugs on the oncokinome.
