  • Patent number: 8778890
    Abstract: This invention provides compounds that are true antagonists of the leptin receptor, in the presence and the absence of native leptin or another leptin receptor binder. These compounds may be used to inhibit leptin receptor activity, promote growth arrest or death of leptin receptor-positive cancer cells, or monitor or detect a leptin receptor-positive cell, in vitro or in vivo. These compounds may also be used to treat a weight-loss nutritional disorder, osteoporosis, rheumatoid arthritis, osteoarthritis, or inflammatory bowel disease. Also included in the invention are methods for detecting leptin receptor-positive cells, for arresting cell growth or killing cancer cells in vivo, for monitoring or detecting a leptin receptor-positive cell in vitro or in vivo, for treating a weight-loss nutritional disorder, for treating osteoporosis, for treating rheumatoid arthritis, for treating osteoarthritis, or for treating inflammatory bowel disease.

  • Publication number: 20060240494
    Abstract: A method for identifying a compound that has a biocidal effect against a selected organism involves screening from among known or unknown peptide or non-peptide molecules, a test molecule that binds selectively to a target sequence of a multi-helical lid of a heat shock protein of the organism. The binding of the test compound inhibits the protein folding activity of the protein. A specific embodiment of such a method is useful for identifying or designing a pharmaceutical or veterinary biocidal or antibiotic compound, preferably a pathogen and/or strain-specific compound. For this purpose, the compound does not bind to a heat shock protein that is homologous to the mammalian subject to be treated with the compound. Screening methods can encompass direct binding or competitive assays. Molecules or compounds identified by these methods are employed as biocides for pharmaceutical, veterinary, pesticide, insecticide and rodenticide uses, among others.

  • Patent number: 7015309
    Abstract: Modifications of the peptide pyrrhocoricin permit the production of a variety of anti-bacterial or anti-fungal peptides having general formula R1-Asp-Lys-Gly-X-Y-Leu-Pro-Arg-Pro-Thr-Pro-Pro-Arg-Pro-Ile-Tyr-X?-Y?-R2 SEQ ID NO: 1 or multimeric compositions containing more than a single peptide of that formula. These peptides may be straight chain or cyclic peptides, and may contain one or more non-cleavable bonds. These peptides are characterized by anti-bacterial or anti-fungal activity and metabolic stability in mammalian serum. These peptides are useful in anti-bacterial or anti-fungal pharmaceutical compositions and for further drug development or identification of other antibiotic or anti-fungal compounds.
