PEPTIDE ANALOGUES, AND THEIR USES IN PARTICULAR IN PHARMACEUTICAL COMPOSITIONS AND FOR DIAGNOSIS

摘要

The invention concerns the use of parent peptide analogues, characterised in that they correspond to said parent peptide in which: at least a peptide bond -CO-NH- of the peptide chain, is modified, except for retro or retro-inverso type modifications; or at least an amino acid of the peptide chain, is substituted by a non-proteinogenic amino acid; or at least a peptide bond -CO-NH- of the peptide chain is substituted by a non proteinogenic amino acid. Said peptide analogues are used for: preparing medicines for preventing or treating the pathologies mentioned in the description; or preparing a composition for diagnosing said pathologies, or for assessing in vivo the immune response concerning said pathologies, using a hypersensitivity cutaneous reaction by intradermal injection of said composition; or implementing an in vitro diagnostic method of said pathologies.
