    摘要: The present invention provides novel PAR 1 derived cytoprotective oligopeptides or polypeptides which typically contain at least the first 4 N-terminal residues that are substantially identical to the corresponding N-terminal residues of Met1-Arg46 deleted human PAR 1 sequence. These cytoprotective oligopeptides or polypeptides are capable of activating PAR 1 and promoting PAR 1 cytoprotective signaling activities. The invention also provides engineered cells or transgenic non-human animals which harbor in their genome an altered PAR 1 gene that is resistant to cleavage at Arg41 and/or Arg46 residues. Additionally provided in the invention are methods of screening candidate compounds to identity additional cytoprotective compounds or cytoprotective proteases. The invention further provides therapeutic use or methods of employing a PAR 1 derived cytoprotective oligopeptide or polypeptide to treat conditions associated with tissue injuries or undesired apoptosis.

    摘要: Arylomycin analogs are provided, wherein the analogs can have broad spectrum bioactivity. Resistance to the antibiotic bioactivity of natural product arylomycin in a range of pathogenic bacterial species has been found to depend upon single amino acid mutations at defined positions of bacterial Signal Peptidases (SPases), wherein the presence of a proline residue confers arylomycin resistance. Arylomycin analogs are provided herein that can overcome that resistance and provide for a broader spectrum of antibiotic bioactivity than can natural product arylomycins such as arylomycin A2. Methods for determining if a bacterial strain is susceptible to narrow spectrum arylomycin antibiotics, or if a broad spectrum analog is required for treatment, is provided. Pharmaceutical compositions and methods of treatment of bacterial infections, and methods of synthesis of arylomycin analogs, are provided.
