摘要: The present invention provides lipidoids that can be used to modulate the immune response in a subject. Lipidoids are prepared by the conjugate addition of an amine to an acrylate to acrylamide. The lipidoids form complexes or particles with an immunostimulatory polynucleotide, which are then administerd to a subject. Such compositions have been found to stimulate the production of cytokines and increase both humoral and cell-mediate immune response. The invention also provides pharmaceuti-cal compositions thereof and methods for using the same.

摘要: This invention relates generally to composites comprising a plurality of nanostructures, and methods of making the same. In some embodiments, the composites further comprise a polymer. In some embodiments, the composites may have desirable properties such as, for example, biodegradability, biocompatibility, and/or high tensile strength. In one embodiment, the plurality of nanostructures comprises carbon nanotubes, and the polymer comprises a poly(beta-amino ester). Various methods are provided for preparing the composites. For example, the polymer and the plurality of nanostructures may, in some embodiments, be combined in a layer-by-layer process to form the composite. High throughput methods for preparing composites having different compositions also are provided for screening composites for desirable properties.

摘要: Aminoalcohol lipidoids are prepared by reacting an amine with an epoxide-terminated compound are described. Methods of preparing aminoalcohol lipidoids from commercially available starting materials are also provided. Aminoalcohol lipidoids may be prepared from racemic or stereochemically pure epoxides. Aminoalcohol lipidoids or salts forms thereof are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems. Given the amino moiety of these aminoalcohol lipidoid compounds, they are particularly suited for the delivery of polynucleotides. Complexes, micelles, liposomes or particles containing the inventive lipidoids and polynucleotide have been prepared. The inventive lipidoids may also be used in preparing microparticles for drug delivery. They are particularly useful in delivering labile agents given their ability to buffer the pH of their surroundings.

摘要: Described herein are inventive compositions and methods relating to polymer conjugates and, in particular, to polymer conjugates having pendant side groups comprising ring moieties. In one aspect, embodiments are generally related to compositions that mimic naturally-occurring polyphenol compounds. The compositions comprise, in some embodiments, a polymer backbone having a plurality of hydroxyaromatic pendant side groups or derivatives thereof. For example, in some cases, a pendant side group may be a phenol or a substituted derivative thereof. In some cases, the pendant side group may be an oxidized hydroxyaromatic group, such as a quinone. In some embodiments, self-assembled structures comprising one or more of the polymer conjugates are provided. For example, the polymer conjugates may be combined with a complexing agent to form a particle. In some cases, a polymer conjugate may form a hydrogel. In some embodiments, the self-assembled structures may contain an agent, such as a pharmaceutically active agent. Also provided are methods and kits for forming the compositions, methods of using the compositions, and the like.
