    • The present invention relates to specific inhibitors of the cysteine protease dipeptidyl peptidase I (DP I)which can be used in the treatment of malignant cell degeneration, immune diseases impaired wound healing and metabolic diseases of humans and are represented by the general formula and the pharmaceutical salts thereof, in which R is a peptide or a branched or unbranched C1–C9 alkyl chain, a branched or unbranched C2–C9 alkenyl chain, a branched or unbranched C2–C9 alkynyl chain, a C3–C9 cycloalkyl, C4–C9 carbocyclic, C5–C14 aryl, C3–C9 heteroaryl, C3–C9 heterocyclic, all of the above residues optionally being substituted, the residue AS—AS is a dipeptide or a mimetic thereof, AS is an amino acid or a peptide mimetic thereof. The amino acid is peptide bound with R and R′ is a branched or unbranched C1–C9 alkyl chain, a branched or unbranched C2–C9 alkenyl chain, a branched or unbranched C2–C9 alkynyl chain, a C3–C9 cycloalkyl, C4–C9 cycloalkenyl, C2–C9 heterocycloalkyl, C3–C9 heterocycloalkenyl, C5–C14 aryl, C3–C9 heteroaryl, C3–C9 heterocyclic, whereas the heterocycloalkyl, heterocycloalkenyl, heteroaryl, heterocyclic residue can have up to 6 hetero ring atoms, an amino acid or a peptide mimetic thereof, all of the above residues may be optionally substituted, or is H.
