Patent number: 9683982Abstract: In a method for diagnosing and/or prognosis of cancers, diagnosing origin of tumor cells, optimizing cancer therapy, and screening active substances for oncology, the mechanical properties of tumor cells and reference cells are analyzed under mechanical load that causes linear or non-linear deformation of the loaded cell. The engineering strain of the cells caused by directed mechanical stress being introduced is used to determine metastasis risk and the presence of uncontrollably proliferating and/or invasive cells, or the origin of the tumor. The metastasis risk is determined based on the proportion of cells in the sample exhibiting engineering strain in a direction opposite to the stressing direction. The risk of the presence of uncontrollably proliferating cells for non-linear deformation of the cell is determined in the sample based on the mean value of the engineering strain in the direction of cell stressing.Type: GrantFiled: April 3, 2015Date of Patent: June 20, 2017Assignee: Universität LeipzigInventors: Josef Käs, Jochen Guck

Publication number: 20170088591Abstract: 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.Type: ApplicationFiled: July 11, 2016Publication date: March 30, 2017Applicant: UNIVERSITAT LEIPZIGInventors: Ralf HOFFMANN, Nicole BERTHOLD, Friederike NOLLMANN
