    • This invention firstly provides a method for purifying particular compounds of peptide or pseudo-peptide structure in which the number of protonable basic functions is greater than the number of acid functions and which have a molecular weight of less than 1000 daltons, by ion exchange displacement chromatography. In the method of the present invention the stationary phase used is a cationic exchange resin or a cross-linked polymer matrix activated with acid groups; the transporter solvent used is water if the compound to be purified already possesses at least one net positive charge, or aqueous dilute solutions of inorganic or strong organic acids which protonate the basic groups of the peptide or pseudo-peptide to be separated without modifying the structure of the peptide compound, such as acetic acid, trifluoroacetic acid, formic acid, hydrochloric acid or sulphuric acid; the displacer compound used is a triethylenetetraammonium salt.

    • A process for the solid-phase synthesis of a peptide containing at least one retro-inverso amide bond characterized in that :

      a) the C-terminal partial peptide sequence up to the bond which has to be retro-inverted is synthesized by stepwise condensation of the amino acids suitably protected at the amino group as well as at the side chain functional groups, on a solid support which is insoluble in the reaction medium,
      b) the dipeptide derivative of general formula (I) :
      wherein
      Fmoc is N-9-fluorenylmethoxycarbonyl, and
      R and R₁, each independently, represent the side-chain residues of natural amino acids wherein the functional groups, if any, are suitably protected,
      is coupled to the amino terminus of the partial peptide sequence covalently bound to the solid insoluble support,
      c) the Fmoc amino-protecting group is cleaved from the peptide bound to the solid insoluble support,
      d) the whole sequence of the desired retro-inverso peptide is then stepwise built up by conventional procedures
      e) the thus obtained retro-inverso peptide is detached from the solid insoluble support and purified.
