  • Patent number: 7635480
    Abstract: The present invention provides a compound chosen from: a peptide represented by the sequence SEQ ID No: 1 below: SEQ ID No: 1 Lys-Ala-Lys-Pro-Val-Gln-Lys-Leu-Asp-Asp-Asp-Asp-Asp-Gly-Asp-Asp-Thr-Tyr-Lys-Glu-Glu-Arg-His-Asn-Lys and homologs of this peptide exhibiting at least 80% similarity with the sequence SEQ ID No: 1 and comprising from 20 to 30 amino acids. These compounds are useful in preventing, diagnosing and treating animal and/or human leptospirosis.

  • Publication number: 20070197432
    Abstract: Compounds (I) that are the peptide of sequence (1), its homologs with at least 60% homology, or their salts, functional fragments, chemical analogs and chemical derivatives, are new. Compounds (I) that are the peptide of sequence (1), its homologs with at least 60% homology, and their salts, functional fragments, chemical analogs and chemical derivatives are new. Chemical analogs have one or more amino acids (aa) replaced by the D-enantiomer or a non-natural aa or one or more peptide bonds replaced by isosteres such as CH2NH, CH2S, CH2CH2, CH?CH, COCH2, CH(OH)CH2 or CH2SO. Chemical derivatives are des-alpha amino peptides; N-alpha-acyl substituted by RCO; derivatives substituted at C-terminal carboxy by amino, OR, SR or NHR; derivatives containing a pharmacophore, and polymers of the peptides. R=1-50C alkyl, alkenyl, alkynyl, aryl or cyclic group.
