    摘要: New partially retro-inverted tuftsin analogues of general formula I
    wherein
    R represents the side-chain of the amino acids threonine, methionine or leucine
    R¹ represents the side-chain of the amino acids lysine or arginine
    R² is hydrogen or a metabolically labile acyl group,
    all the asymmetric carbon atoms are either of the S- or R-configuration, or, alternatively, the first, third, and fourth asymmetric carbons, starting from the N-terminal residue, are of the S-configuration while the second one is of the R- or (R,S)-configuration, and the corresponding pharmacologically acceptable salts, esters and amides.
    The new compounds which share the same pharmacological properties of tuftsin, are much more stable toward the enzymatic degradation than the parent molecule.

    摘要: The present invention refers to a new class of malonic acid derivatives of general formula I
    wherein R¹ and R², each independently, represent hydrogen or a carboxyl protecting group, and the residue R corresponds to the side-chain of the amino acids lysine, ornithine, tyrosine, cysteine, aspartic acid and glutamic acid wherein the additional functionalities are suitably protected.
    The new compounds of the present invention are useful for preparing analogues of biologically active peptides wherein the direction of some amide bonds in which the amino acids lysine, ornithine, tyrosine, cysteine, aspartic acid or glutamic acid are involved, has been reversed.
