    摘要: Polysaccharides comprising at least 5 sialic acid residues per molecule are used to increase the circulation time of an active ingredient, for instance by decreasing the immunogenicity and/or increasing the stability in vivo of pharmaceutically active compounds. The pharmaceutically active compound may be a foreign protein which is covalently bound to the polysaccharide. Alternatively, the active compound may be associated with a drug delivery system (DDS), for instance a macro-molecular DDS or a particulate DDS, such as liposomes. The polysaccharide is usually a bacterial polysaccharide, e.g., a glycolipid or a derivative thereof, for instance polysaccharide B or E. Coli K1, N. meningitidis, Moraxella liquifaciens or Pasteurella aeroginosis, or K92 of E. Coli K92 strain.

    摘要: A method of producing microparticles having a median diameter up to 100 μm and the microparticles so produced are described. The method includes the steps of providing a solvent having a bioactive dispersed or dissolved therein and a vehicle dissolved therein, carrying out an emulsification in a non-solvent phase to produce an emulsion containing the bioactive and the vehicle in a solvent phase, and evaporating the solvent to leave the microparticles, wherein a mixture of at least two surfactants is employed to stabilize the emulsion and wherein the mixture has a hydrophilic-lipophilic balance (HLB) of up to 8.

    摘要: Synthetic peptides are widely used to generate antibodies. To induce high antibody response, it is known to conjugate the peptide to a carrier protein (e.g. KLH, BSA) or to incorporate it into polylysine to form a multiple antigenic peptide. Anchors may be built in which are based on fatty acids. According to the invention there is provided a novel lipidic amino acid based anchor system which can maximally enhance the antigenicity of a short synthetic peptide. These novel compounds are entirely peptide-based and may therefore be produced automatically by some step wise peptide synthesis, preferably solid phase step wise peptide synthesis. According to the invention there is also provided such a process.
