  • Patent number: 11857679
    Abstract: The subject invention pertains to polyacrylate homopolymers produced from acrylolated drug monomers. The homopolymers can be produced in the form of nanoparticles. The nanoparticles comprising the homopolymers can be produced via a free radical-induced emulsion polymerization of the acrylolated drug monomers to produce an aqueous emulsion of uniformly sized nanoparticles. The homopolymers of the invention containing acrylolated antibiotic monomers can be active against Gram-positive and Gram-negative bacteria, such as Staphylococcus aureus and Escherichia coli. Accordingly, methods are provided of treating a disease, for example, an infection, by administering to a subject the homopolymers, homopolymeric nanoparticles, or emulsions containing homopolymeric nanoparticles of the invention.

  • Patent number: 10588860
    Abstract: The present invention comprises poly(vinyl benzoate) nanoparticle suspensions as molecular carriers. These nanoparticles can be formed by nanoprecipitation of poly(vinyl benzoate) in water using Pluronic F68 as surfactant, to create spherical nanostructures measuring about 200-250 nm in diameter which are stable in phosphate buffer and blood serum, and only slowly degrade in the presence of esterases. Kinetics experiments in phosphate buffer indicate that 78% of the coumarin-6 was encapsulated within the polymer matrix of the nanoparticle, and the residual 22% of coumarin-6 was surface-bound and quickly released. The nanoparticles are non-toxic in vitro towards human epithelial cells (IC50>1000 ?g/mL) and primary bovine primary aortic endothelial cells (IC50>500 ?g/mL), and exert non-observable bactericidal activity against a selection of representative test microbes (MIC>250 ?g/mL).

  • Patent number: 9149440
    Abstract: This invention relates to polymeric nanoparticles useful for drug delivery with target molecules bonded to the surface of the particles and having sizes of up to 1000 nm, preferably 1 nm to 400 nm, more preferably 1 nm to 200 nm, that are dispersed homogeneously in aqueous solution. The target drug/target substance is covalently bonded to the novel polymeric nanoparticles to secure them from outer intervention in vivo or cell culture in vitro until they are exposed at the target site within the cell. This invention also relates to microemulsion polymerization techniques useful for preparing the novel nanoparticles.
