Sirlei Daffre has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Antimicrobial peptide, compositions, and uses therefor
    Patent number: 7723468
    Abstract: The invention refers to small peptides with low hemolytic activity, presenting similar antiparasitic, antifungal and antibacterial activities. More specifically, it refers to a peptide called gomesin, with 18 amino acid residues, configured as a hairpin structure consisting of two anti-parallel beta-folded sheets joined by a beta turn, containing four invariable residues of cysteine forming two disulphide bridges, configurable as a cyclic chain with open or closed ends.
    Type: Grant

  • Antimicrobial peptide, process to obtain a peptide and uses therefor
    Publication number: 20030186854
    Abstract: The invention refers to small peptides with low hemolytic activity, presenting equal antiparasitic, antifungal and antibacterial activities. More specifically, it refers to a peptide called gomesin, with 18 amino acid residues, configured as a clamp-like structure consisting of two anti-parallel beta-folded sheets joined by a beta turn, containing four invariable residues of cystein forming two disulphide bridges, optionally configurable as a cyclic chain with closed edges.
