  • Patent number: 11789029
    Abstract: A unique pipeline is employed for biomarker discovery that entailed domain antibody phage display, next generation sequencing analysis, and nanotechnology strategies to generate antibody mimetics are disclosed. Also disclosed are the temporal biomarkers of traumatic brain injury and their methods of use. In some embodiments, the temporal biomarkers are synthetic peptides comprising the HCDR3 sequences identified using the disclosed pipeline. In some aspects, the synthetic peptides have less than 30 amino acid residues and comprise a biotin scaffold that is linked to the HCDR3 sequences.

  • Patent number: 11752195
    Abstract: Synthetic antimicrobial peptides, compositions comprising thereof, and methods of use for modulating one or more symptoms of an infection in a subject are disclosed. In some aspects, the infection is caused by mycobacteria, for example, a nontuberculous mycobacterium such as Mycobacterium abscessus. In other aspects, the infection is caused by Escherichia coli, Pseudomonas aeruginosa, or methicillin-resistant Staphylococcus aureus (MRSA). Also disclosed are methods of identifying synthetic antimicrobial peptides against a pathogen with no known effective treatment using a library of synthetic peptides.

  • Patent number: 10125167
    Abstract: Provided herein are compounds and compositions having antibiotic activity against methicillin resistant Staphylococcus aureus (MRSA). In particular, provided herein is a synbody that bactericidal against multiple strains of MRSA and that can be used in conjugation with currently approved ?-lactam antibiotics to treat MRSA strains having resistance to ?-lactam treatment. Also provided are methods of using the compounds and compositions for treating, preventing or reducing MRSA infections.

  • Patent number: 9757472
    Abstract: Improved peptide compositions and synbody compositions are disclosed that show improved stability and antibiotic activity. The new antibacterial peptides for S. aureus have particular D-amino acid substitutions in order to increase protease stability while also preserving marked antibiotic activity. Thus, compositions and methods for treating infections related to S. aureus also are disclosed.
