- Integrins are membrane-bound, heterodimeric glycoproteins that consist of an ⁇ subunit and a smaller ⁇ subunit. The relative affinity and specificity for ligand binding is determined by combining the different ⁇ and ⁇ subunits. According to the
- the object of the invention was to find new compounds with valuable properties, in particular those which are used for the production of medicaments.
- the compounds of the formula I, their stereoisomers and their salts have very valuable pharmacological properties with good tolerability.
- the compounds are particularly notable for their very high activity. They act as antagonists of integrin receptors, in particular the ⁇ v ⁇ 3 , ⁇ v ⁇ and / or the ⁇ v ⁇ 6 integrin receptors. They also have octanol / water very favorable distribution coefficients in octctanol / water (logD values).
- an active ingredient is added to a mixture of octanol / water, it is distributed between the two phases at a given pH value according to its lipophilicity / hydrophilicity.
- the ratio of the distribution of the active substance between the octanol and water phase is called the distribution coefficient. Absorption of active ingredients requires that they both dissolve in aqueous media and penetrate the corresponding membranes. For the latter, there is a certain lipophilicity of the
- the integrins have different physiological and pathological functions, which can be found in detail, for example, in the following review articles: Integrins and Signal transduction. Dedhar-S, Curr-Opin-Hematol. 1999 Jan; 6 (1): 37-43, Integrins take partners: cross-talk between integrins and other membrane receptors. Porter JC; Hogg-N, Trends Cell Biol. 1998 Oct; 8 (10): 390-6, Regulation of integrin-mediated adhesion during cell migration. Cox EA; Huttenlocher-A, Microsc-Res-Tech. 1998 Dec 1; 43 (5): 412-9, The role of integrins in the malignant phenotype ofgliomas.
- ⁇ v ß 6 epithelial integrins there are also ⁇ v ß 6 epithelial integrins. Sheppard-D bioessays. 1996 Aug; 18 (8): 655-60 and the two integrins ⁇ v ß 3 and ⁇ vßs, which represent known adhesion receptors, the biological meaning of which, for example, in JA Varner et al. Cell Adhesion and
- ocvß ⁇ is a relatively rare integrin (Busk et al., 1992 J. Biol. Chem. 267 (9), 5790), which is increasingly formed in repair processes in epithelial tissue and preferentially binds the natural matrix molecules fibronectin and tenascin (Wang et al., 1996, Am. J. Respir. Cell Mol. Biol. 15 (5), 664).
- the physiological and pathological functions of ⁇ v ß ⁇ are not yet exactly known, but it is suspected that this integrin is associated with physiological processes and diseases (e.g. inflammation,
- ⁇ v ß ⁇ is expressed on keratinocytes in wounds (Haapasalmi et al., 1996, J. Invest. Dermatol. 106 (1), 42), from which it can be assumed that in addition to wound healing processes and inflammation, other pathological events of the skin, such as, for example, , B. psoriasis
- v ⁇ ⁇ plays a role in the respiratory epithelium (Weinacker et al., 1995, Am. J. Respir. Cell Mol. Biol. 12 (5), 547), so that corresponding agonists / antagonists of this integrin in respiratory diseases, such as bronchitis, Asthma, pulmonary fibrosis and respiratory tumors could be used successfully.
- ⁇ v ⁇ ⁇ also in the intestinal epithelium Role plays, so that appropriate lnteghn agonists / antagonists could be used in the treatment of inflammation, tumors and wounds of the gastrointestinal tract.
- Microorganisms and viruses also have integrin receptors, in particular ⁇ v ⁇ 6 receptors.
- ⁇ v ß 5 receptors are receptors for example, ⁇ v ß 5 receptors are receptors for example, ⁇ v ß 5 receptors are receptors for example, ⁇ v ß 5 receptors are receptors for example, ⁇ v
- Adenoviruses or ⁇ v ß 5 / v ßs -receptors for HIV could therefore also be used to treat infections, in particular viral infections.
- ⁇ v ß 3 or ⁇ vßs integrin receptors are expressed on a number of cells, for example endothelial cells, cells of the smooth vascular muscles, for example the aorta, cells for breaking down bone matrix (osteoclasts) or tumor cells.
- Antibodies against v ß 3 described that cause tumor shrinkage by inducing apoptosis.
- Preventing matrix proteins and accordingly also preventing tumor cells from attaching to matrix proteins can be performed in a cell adhesion test, analogously to the method by F. Mitjans et al., J. Cell Science 1995, 108, 2825-2838.
- the compounds of the formula I can inhibit the binding of metalloproteinases to integrins and thus prevent the cells from being able to use the enzymatic activity of the proteinase.
- An example can be found in the inhibition of the binding of MMP-2- (matrix-metallo-proteinase-2) to the vitronectin receptor ⁇ v ß 3 by a cyclo-RGD peptide, as in PC Brooks et al., Cell 1996, 85, 683-693.
- micro-aggregates can attach themselves to the vessel walls, which facilitates further penetration of tumor cells into the tissue. Since the formation of the microthrombi is mediated by ligand binding to the corresponding integrin receptors, eg ⁇ v ß 3 or ⁇ n b ß 3 , on activated platelets, the corresponding antagonists can be regarded as effective metastasis inhibitors.
- the compounds can be administered to humans or animals locally or systemically, orally, intravenously, intraperitoneally, intramuscularly, subcutaneously, transdermally, nasally, buccally or iontophoretically.
- a measure of the absorption of an active pharmaceutical ingredient into an organism is its bioavailability.
- the active pharmaceutical ingredient is added intravenously to the organism in the form of a solution for injection, its absolute bioavailability lies, i.e. the proportion of the drug that remains unchanged in the systemic blood, i.e. gets into the big cycle, at 100%.
- the active ingredient When a therapeutic active ingredient is administered orally, the active ingredient is usually present as a solid in the formulation and must therefore first dissolve in order for it to overcome the entry barriers, for example the
- Gastrointestinal tract, the oral mucosa, nasal membranes or the Skin, especially the stratum corneum, can overcome or be absorbed by the body.
