    摘要: α-Aminoamidine polymers and methods of preparing a-aminoamidine polymers by reacting by reacting one or more amines with one or more isocyanides and one or more aldehydes are described. Methods of preparing a-aminoamidine polymers from commercially available starting materials are also provided, wherein the starting materials are racemic or stereochemically pure. a-Aminoamidine polymers or salt forms thereof are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems and for other purposes as well such as, for example, coatings, additives, excipients, plastics, and materials, etc. Given the amino moiety of these α-aminoamidine polymers, they are particularly suited for the delivery of polynucleotides. Complexes, micelles, liposomes or particles containing the inventive α-aminoamidine polymers and polynucleotides can be prepared. The inventive α-aminoamidine polymers 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: Biomedical devices for implantation with decreased pericapsular fibrotic overgrowth are disclosed. The device includes biocompatible materials and has specific characteristics that allow the device to elicit less of a fibrotic reaction after implantation than the same device lacking one or more of these characteristic that are present on the device. Biocompatible hydrogel capsules encapsulating mammalian cells having a diameter of greater than 1 mm, and optionally a cell free core, are disclosed which have reduced fibrotic overgrowth after implantation in a subject. Methods of treating a disease in a subject are also disclosed that involve administering a therapeutically effective amount of the disclosed encapsulated cells to the subject.
