Abstract: A drug targeting system for administering a pharmacologically active substance to the central nervous system of a mammal across the animal's blood brain barrier. The drug targeting system comprises nanoparticles made of poly(DL-lactide) and/or poly(DL-lactide-co-glycolide), a pharmacologically active substance which is absorbed to, adsorbed to, and/or incorporated into the nanoparticles, and either contains TPGS or comprises a pluronic 188 surfactant coating deposited on the drug-loaded nanoparticles.

Abstract: Combination preparations comprising at least one apolipoprotein as one component, and a medicinal agent to be transported via the blood-brain barrier to the central nervous system as a further component. The components are administered simultaneously, separately or sequentially. A method for administering a medicinal agent to the central nervous system is also provided.

Abstract: Active agent-loaded nanoparticles that are based on a hydrophilic protein or a combination of hydrophilic proteins, and methods for producing the nanoparticles and the use thereof. Functional proteins or peptide fragments are bound to the nanoparticles via polyethylene glycol-?-maleimide-?-NHS esters.

Abstract: Nanoparticles, the particle matrix of which is based on at least one protein and has at least one active agent embedded therein and methods of producing the nanoparticles with at least one active agent embedded in the protein matrix are disclosed. The use of the nanoparticles for the treatment of tumours, in particular for the treatment of tumours which are resistant to chemical medicaments is also disclosed.

Abstract: A carrier system in the form of protein-based nanoparticles for the cell-specific, intracellular enrichment of at least one pharmacologically active substance. The system has structures that are coupled by reactive groups. The structures enable a cell-specific attachment and cellular absorption of the nanoparticles.

Abstract: The invention relates to a method for the simplified isolation in high yields of sponge collagen, especially from marine sponges, and to the production of collagen nanoparticles from collagen. The invention further relates to the use thereof for influencing cell-dependent processes in vitro and in vivo, especially when orally or topically administered to treat inflammatory, preferably cyclooxygenase-dependent diseases.

Abstract: The invention relates to medicament excipient particles which are suitable for tissue-specific application of a medicament, especially to the central nervous system (CNS). The invention particles can be loaded with or be free pf the active substance. At least one detection protein is bonded to the particle surface or alternatively, the particle surface is modified in such a way that a detection protein bonds with it on contact.

Abstract: The medicament in particulate form has one or more anionic or partially anionic active substances bound to a carrier material. The carrier material includes particulate copolymer or homopolymer of acrylic acid or acrylic acid ester or methacrylic acid esters. The carrier further includes oxygen in the ester group, a branched or unbranched alkyl chain with 2-10 carbon atoms, --NR.sub.2 where R represents H and lower alkyl chains in any combination, and H or a lower alkyl chain. The grain size distribution of the carrier is 10-1000 nm.

Abstract: A novel method of delivering drugs and diagnostics across the blood-brain barrier or blood-nerve barrier is disclosed. Drugs or diagnostic agents are incorporated into nanoparticles which have been fabricated in conventional ways. These nanoparticles are then coated with additional surfactant and given to the body of animals or humans. This allows drugs or diagnostic agents to cross the blood-brain barrier (bbb) to achieve one or more of the following benefits: (1) reducing the dose of a therapeutic drug or diagnostic agent which, when given peripherally, maintains the biological or diagnostic potency in the nervous system, (2) allowing drugs that normally do not cross the bbb to penetrate into the nervous system, and (3) reducing the peripheral side effects by increasing the relative amount of the drug reaching the brain.

Abstract: There are described processes for the preparation of submicroscopic particles of physiologically acceptable polymer associated with a biologically active material, by polymerizing a monomer in the presence of the biologically active material or by adsorbing the biologically active material upon preformed submicroscopic polymer particles. Where the biologically active material is an antigen, the particles are useful as constituents of injectable vaccines having an adjuvant effect.
