Abstract

The invention relates to a method for inhibiting the DNA synthesis of human fibroblasts that is necessary for proliferation, by the individual or combined action of inhibitors of alanyl-aminopeptidase (APN) and dipeptidylpeptidase IV (DP IV) that is expressed by said cells. The DNA synthesis (proliferation) of human fibroblasts is inhibited by a dosage-dependent administration of the APN and/or the DP IV. According to the invention, the application of inhibitors of the aforementioned enzyme or of preparations and administrable forms containing said inhibitors is eminently suitable for the treatment and prevention of dermatological diseases involving fibroblastic hyperproliferation and modified differentiation conditions of fibroblasts.

Description

Use of the inhibitors of enzymes with activities of the aminopeptidase N and / or the dipeptidyl peptidase IV and pharmaceutical preparations therefrom for the therapy and prevention of dermatological diseases with hyperproliferation and changed differentiation states of fibroblasts

description

The invention describes the inhibition of the DNA synthesis of fibroblasts necessary for the proliferation and differentiation by the action of inhibitors of aminopeptidase N (APN, EC 3.4.11.2, CD13) or / and dipeptidyl peptidase IV (DP IV, EC 3.4.14.5, CD26) as a result of the individual, simultaneous or immediately sequential application of respectively specific inhibitors of these enzymes or of inhibitors of enzymes of the same substrate specificity (APN- and / or DP IV-analogous enzyme activity) on the basis of amino acid derivatives, peptides or peptide derivatives, by which the proliferation (DNA synthesis) and differentiation of fibroblasts is suppressed and modulated.

A number of dermatological diseases are associated with hyperproliferation and changes in the differentiation states of fibroblasts. They include both benign fibroblastic hyperproliferative conditions (here in particular post-infectious, post-inflammatory and post-traumatic: hypertrophic scars, keloids, angiofibromas, dermatofibromas, fibrolipomas, ulcer scars), which also occur in the context of disseminated (myo-) fibromatoses (e.g. congenital fibromatosis) also malignant fibroblastic hyperproliferative states (e.g. fibrosarcomas, mixed tumors such as atypical fibroxanthoma, malignant fibrous histiocytoma, aggressive angiomyxoma, paraneoplasias). Form another group of diseases Fibrous autoimmune diseases such as localized and systemic scleroderma in its various forms (circumscript S., progressive-systemic S., CREST syndrome), dermatosclerosis in other collagenoses and the cutaneous variant of the graft-versus-host disease. Changes in the differentiation states of the fibroblasts are an expression of various fibrosing diseases with a currently largely unexplained atiology. These include the Liehen scierosus et atrophicus and the heterogeneous group of pseudoscleroderma (such as eosinophilic / proliferating fasciitis, exogenously caused pseudoscleroderma such as toxic oil syndrome, silicosis, porphyrias, eosinophilia-myalgia syndrome, Liehen associated myxoedema syndrome). There are also secondary sclerotherapy such as stasis fibrosis for chronic venous insufficiency and lipolymphedema, late fibrosis of alopecia androgenetica, and rare localized fibroblastic diseases (Dupuytren disease, Ledderhose disease, "knuckle pads", induration penis plastica).

Peptidases such as dipeptidyl petidase IV and aminopeptidase N or enzymes with a similar effect are particularly interesting for the regulation or modulation of interactions between cells, since they are partly located as ectoenzymes in the plasma membrane of the cells, interact with other extracellular structures, peptide messengers activate or inactivate by enzyme-catalyzed hydrolysis and are therefore important for cell-cell communication [Yaron A, et al .: Proline-dependent structural and biological properties of peptides and proteins. Grit Rev Biochem Mol Biol 1993; 28: 31-81; Vanhoof G, et al .: Proline motifs in peptides and their biological processing. FASEB J 1995; 9: 736-744].

It has been shown that membrane-active peptidases such as DP IV or APN play a key role in the process of activation and clonal expansion of immune cells, in particular T lymphocytes [Fleischer B: CD26 a surface protease involved in T-cell activation. Immunology Today 1994; 15: 180-184; Lendeckel U et al .: Role of alanyl aminopeptidase in growth and function of human T cells. International Journal of Molecular Medicine 1999; 4: 17-27; Riemann D et al .: CD13 - not just a marker in leukemia typing. Immunology Today 1999; 20: 83-88]. Various functions of mitogen-stimulated mononuclear cells (MNZ) or enriched T lymphocytes such as DNA synthesis, production and secretion of immunostimulatory cytokines (IL-2, IL-6, IL-12, IFN-γ) and helper functions for B cells ( IgG and IgM synthesis) can be inhibited in the presence of specific inhibitors of DP IV or APN [Schön E et al .: The dipeptidyl peptidase IV, a membrane enzyme involved in the proliferation of T lymphocytes. Biomed. Biochim. Acta 1985; 2: K9-K15; Schön E et al .: The role of dipeptidyl peptidase IV in human T lymphocyte activation.

Med. 1999; 4: 3-15; Lendeckel U et al .: Role of alanyl aminopeptidase in growth and function of human T cells (review). Int. J. Mol. Med. 1999; 4: 17-27].

It is already known that the treatment of autoimmune diseases and graft rejection is possible by inhibiting the dipeptidyl petidase IV localized on immune cells with the aid of synthetic inhibitors (e.g. EP-A 0 764151, WO095 / 29691, EP-A 0 731 789, EP -A 0 528 858).

The invention is based on the surprising finding that the individual or simultaneous effect of inhibitors of on or in fibroblasts expressed dipeptidyl peptidase IV / DP IV or CD26 or of inhibitors of enzymes with the same substrate specificity (DP IV-analogous enzyme activity) and of inhibitors of aminopeptidase N / APN or CD13 or of inhibitors of enzymes with the same substrate specificity (APN-analogous enzyme activity), inhibits the proliferation (DNA synthesis) of fibroblasts.

Our invention shows that for the therapy and prevention of dermatological diseases with fibroblastic hyperproliferation and changed differentiation states, for their development the proliferation and the differentiated regulation of the DNA synthesis of fibroblasts is of central importance, the single or simultaneous application of inhibitors of DP IV and the APN or inhibitors of enzymes of the same substrate specificity (APN- and / or DP IV-analogous enzyme activity) or corresponding preparations and dosage forms thereof are suitable.

In particular, the invention is based on the findings that the DNA synthesis of fibroblasts is significantly inhibited by the administration of inhibitors of dipeptidyl peptidase IV or of inhibitors of enzymes with the same substrate specificity or / and of inhibitors of aminopeptidase N or of inhibitors of enzymes with the same substrate specificity becomes.

The above-mentioned diseases have hitherto been treated topically and / or systemically with immunosuppressants, glucocorticosteroids, non-specific anti-inflammatory agents and emollients, and symptomatically with physiotherapy. In systemic medications in particular, undesirable side effects often occur. These include Cushing's syndrome, osteoporosis, infections or diabetes mellitus. Local therapy focuses on local skin atrophy and increased skin vulnerability. Skin tumors can be propagated in both systemic and local immunosuppressive therapy. The use of DP IV or / and APN inhibitors would represent a completely new, probably very effective, possibly inexpensive form of therapy and a valuable alternative component of the existing therapy concepts, especially in the early stages.

The inhibitors of dipeptidyl peptidase IV applied according to the invention or inhibitors of enzymes with the same substrate specificity (DP IV-analogous enzyme activity) or / and inhibitors of aminopeptidase N or inhibitors of enzymes of the same substrate specificity (APN-analogous enzyme activity) can be used in pharmaceutically acceptable formulation complexes as inhibitors, substrates, Pseudo substrates, inhibitory peptides and peptide derivatives and as antibodies of these enzymes are used. The inhibitors according to the invention are used alone or in combination of several of them, preferably in combination of two of them.

Preferred effectors for the DP IV are Xaa-Pro dipeptides, corresponding derivatives, preferably dipeptide phosphonic acid diaryl esters, dipeptide boronic acids (e.g. Pro-boro-Pro) and their salts, Xaa-Xaa- (Trp) -Pro- (Xaa) n-peptides (n = 0 to 10), corresponding derivatives and their salts or amino acid (Xaa) amides, corresponding derivatives and their salts, where Xaa is preferably an α-amino acid / amino acid or an -amino acid derivative / amino acid derivative N ^ε -4-nitrobenzyloxycarbonyl-L-lysine, L-proline, L-tryptophan, L-isoleucine, L-valine and cyclic amines, for example pyrrolidine, piperidine, thiazolidine and their derivatives, act as the amide structure. Such compounds and their preparation have been described in a previous patent (K. Neubert et al. DD296075A5).

An exemplary, advantageously usable inhibitor of DP IV is Lys [Z (NO ₂ ] thiazolidide, in which Lys stands for an L-lysine residue and Z (NO ₂ ) stands for 4-nitrobenzyloxycarbonyl (cf. DD-A 296075) ,

Examples

Example 1

Our investigations show that the DNA synthesis of human fibroblasts is inhibited in a dose-dependent manner by the administration of inhibitors of DP IV (Lys [Z (Nθ ₂ )] thiazolidide) and / or APN (actinonin).

Human fibroblasts strongly express DP IV and APN (Figure 1). The enzyme activity of the DP IV of vital cells is 57.3 + 12.4 pkat 10 ⁶ cells, that of the APN is 380.5 + 48.2 pkat / 10 ⁶ cells (n = 4). Accordingly, the mRNA of APN and DP IV can be detected on these cells (FIG. 2).

Fibroblasts from healthy donors were incubated for 48 h with the above-mentioned inhibitors and the DNA synthesis was then determined by measuring the ³ [H] thymidine incorporation, as described by Reinhold et al. (Reinhold D et al .: Inhibitors of dipeptidyl peptidase IV induce secretion of transforming growth factor β1 in PWM-stimulated PBMNC and T cells. Immunology 1997; 91: 354-360). Figure 3 shows the dose-dependent inhibition of DNA synthesis.

To measure the dose-dependent effect of DP IV (Lys [Z (N0 ₂ )] thiazolidide) and aminopeptidase N (actinonin) inhibitors on the DNA synthesis of human fibroblasts, the cells were incubated for 48 hours with the indicated concentrations of the inhibitors. Then ³ [H] -methyl-thymidine was added to the culture medium and after a further 6 hours the amount of ³ [H] -thymidine incorporated into the DNA was measured. The results are shown in FIG. 3.
