  • Publication number: 20170107256
    Abstract: This invention relates to modified antibiotic peptides, particularly for use in medicine. The invention further relates to composite and methods for destroying microorganisms, such as bacteria, viruses or fungi, and to methods for treating microbial infections. The object of the invention is to develop novel antibiotic peptides, particularly having enhanced antibiotic activity and an expanded spectrum of activity against other strains of bacteria, particularly gram-positive bacteria such as Staphylococcus aureus. According to the invention, the object is attained in a first aspect by a peptide according to claim 1.

  • Publication number: 20170088591
    Abstract: The invention relates to modified antibiotic peptides, in particular derivatives of apidaecin and oncocin, preferably having increased stability, reduced immunoreaction, and improved pharmacokinetics. In the invention, the peptide antibiotics are reversibly protected by means of a linker having the polymer polyethylene glycol (PEG). The peptide linker contains a recognition sequence for trypsin-like serum proteases. In the apidaecin derivatives, the linker and the PEG are bonded to a side chain. In the serum, the linker is cut by serum proteases and PEG is separated off. The released peptide still contains remnants of the linker, which are still bonded to the amino group in the side chain. Astonishingly, said remaining remnants of the linker impair the activity of the antimicrobial peptide only a little or not at all.

  • Patent number: 8946580
    Abstract: The present invention relates to contactors for unidirectional DC operation with permanent magnetic arc extinguishing. In addition to the blow magnets, the contactors are equipped with compensatory permanent magnets for compensating the magnetic field in the vicinity of the contact bridge in order to prevent contact levitation, i.e., an uncontrolled opening of the contacts that is due to a magnetic force generated by a strong current flowing through the contact bridge. To this end, the compensatory permanent magnets are arranged in the vicinity of the contact bridge and polarized in the opposite direction of the blow magnets. The magnetic field of the compensatory magnets and the current flowing through the contact bridge are generating a magnetic force that acts on the contact bridge and tends to keep the electrical contacts closed.
