and their physiologically acceptable salts. Similar connections are e.g. B. from EP 0 478 363 and EP 0 478 328.

The object of the invention was to find new compounds with valuable properties, in particular those which can be used for the production of medicaments.

It has been found that the compounds of the formula I and their salts have very valuable pharmacological properties with good tolerability. Above all, they act as integrin inhibitors, in particular inhibiting the interactions of the α _v -integrin receptors with ligands. The compounds are particularly effective in the case of the integrins α _v ß3 and α _v ßs. The compounds are particularly effective as adhesion receptor antagonists for the vitronectin receptor α _v ß3. This effect can be demonstrated, for example, by the method described by JW Smith et al. in J. Biol. Chem. 265, 11008-11013 and 12267-12271 (1990).

The inhibition of vitronectin binding to receptors has been experimentally proven for some representative compounds of formula I. The pharmacological test data are summarized in Table I.

B. Felding-Habermann and DA Cheresh describe in Curr. Opin. Cell. Biol. 5, 864 (1993) the meanings of the integrins as adhesion receptors for the most varied phenomena and clinical pictures, especially in relation to the vitronectin receptor α _v β3.

The dependency of the development of angiogenesis on the interaction between vascular integrins and extracellular matrix proteins is described by P.C. Brooks, R.A. Clark and D.A. Cheresh in Science 264, 569-71 (1994).

The possibility of inhibiting this interaction and thus inducing apoptosis (programmed cell death) of angiogenic vascular cells by a cyclic peptide has been discussed by P.C. Brooks, A.M. Montgomery, M. Rosenfeld, R.A. Reisfeld, T.-Hu, G. Klier and D.A. Cheresh in Cell 79,

1157-64 (1994). The experimental proof that the compounds according to the invention also prevent the attachment of living cells to the corresponding matrix proteins and accordingly also prevent the attachment of tumor cells to matrix proteins was provided in a cell adhesion test which, analogously to the method by F. Mitjans et al ., J. Cell Science 108, 2825-2838 (1995). The pharmacological data are listed in Table II.

pc Brooks et al. describe in J. Clin. Invest. 96, 1815-1822 (1995) σ. _v ß3 antagonists for combating cancer and for treating tumor-induced angiogenic diseases.

The compounds of the formula I according to the invention can therefore be used as active pharmaceutical ingredients, in particular for the treatment of tumor diseases, osteoporoses, osteolytic diseases and for suppressing angiogenesis.

The invention accordingly relates to compounds of the formula I according to claim 1 and / or their physiologically acceptable salts for the preparation of a medicament for use as an αv-integrin inhibitor.

The compounds of formula I can be used as active pharmaceutical ingredients in human and veterinary medicine, for the prophylaxis and / or therapy of thrombosis, myocardial infarction, arteriosclerosis, inflammation, apoplexy, angina pectoris, tumor diseases, osteolytic

Diseases such as osteoporosis, pathologically angiogenic diseases such as B. inflammation, ophthalmic diseases, diabetic retinopathy, macular degeneration, myopia, ocular histoplasmosis, rheumatoid arthritis, osteoarthritis, rubeotic glaucoma, ulcerative colitis, Crohn's disease, atherosclerosis, psoriasis, restenosis after angioplasty, infection, viral infection, viral infection in acute kidney failure and in wound healing to support the healing processes. The compounds of formula I can be used as antimicrobial substances in operations where biomaterials, implants, catheters or pacemakers are used. They have an antiseptic effect. The effectiveness of the antimicrobial activity can be demonstrated by P.Valentin-Weigund et al., In Infection and

Immunity, 2851-2855 (1988).

The term "amino protecting group" is generally known and refers to groups which are suitable for protecting (blocking) an amino group against chemical reactions, but which are easily removable after the desired chemical reaction has been carried out at other locations in the molecule is. Unsubstituted or substituted acyl, aryl, aralkoxymethyl or aralkyl groups are particularly typical of such groups. Since the amino protective groups are removed after the desired reaction (or reaction sequence), their type and size is otherwise not critical; however, preference is given to those having 1-20, in particular 1-8, carbon atoms. The term "acyl group" is to be understood in the broadest sense in connection with the present process. It includes acyl groups derived from aliphatic, araliphatic, aromatic or heterocyclic carboxylic acids or sulfonic acids, and in particular alkoxycarbonyl, aryloxycarbonyl and especially aralkoxycarbonyl groups. Examples of such acyl groups are alkanoyl such as acetyl, propionyl, butyryl; Aralkanoyl such as phenylacetyl; Aroyl such as benzoyl or toluyl; Aryloxyalkanoyl such as POA; Alkoxycarbonyl like Methoxycarbonyl, ethoxycarbonyl, 2,2,2-trichloroethoxycarbonyl, BOC, 2-iodoethoxycarbonyl; Aralkyloxycarbonyl such as CBZ ("carbobenzoxy"), 4-methoxybenzyloxycarbonyl, FMOC; Arylsulfonyl such as Mtr. Preferred amino protective groups are BOC and Mtr, furthermore CBZ, Fmoc, benzyl and acetyl.

The amino protective group is split off, depending on the protective group used, e.g. B. with strong acids, suitably with TFA or perchloric acid, but also with other strong inorganic acids such as hydrochloric acid or sulfuric acid, strong organic carboxylic acids such as

Trichloroacetic acid or sulfonic acids such as benzene or p-toluenesulfonic acid. The presence of an additional inert solvent is possible, but not always necessary. Suitable inert solvents are preferably organic, for example carboxylic acids such as acetic acid, ethers such as tetrahydrofuran or dioxane, amides such as DMF, halogenated hydrocarbons such as dichloromethane, and also alcohols such as methanol, ethanol or isopropanol, and water. Mixtures of the abovementioned solvents are also suitable. TFA is preferably used in excess without the addition of another solvent, perchloric acid in the form of a mixture of acetic acid and 70%

Perchloric acid in a ratio of 9: 1. The reaction temperatures for the cleavage are advantageously between about 0 and about 50 °, preferably between 15 and 30 ° (room temperature).

The groups BOC, OBut and Mtr can e.g. B. preferably with TFA in dichloromethane or with about 3 to 5N HCl in dioxane at 15-30 °, the FMOC group with an about 5 to 50% solution of dimethylamine, diethylamine or piperidine in DMF at 15 -30 °.

Hydrogenolytically removable protective groups (e.g. CBZ or benzyl) can e.g. B. by treatment with hydrogen in the presence of a catalyst (z. B. a noble metal catalyst such as palladium, advantageously on a support such as coal). Suitable solvents are the above, especially z. B. alcohols such as methanol or ethanol or amides such as DMF. Hydrogenolysis is usually carried out at temperatures between about 0 and 100 ° and pressure between about 1 and 200 bar, preferably at 20-30 ° and 1-10 bar. Hydrogenolysis of the CBZ group succeeds e.g. B. good on 5 to 10% Pd / C in methanol or with ammonium formate (instead of hydrogen) on Pd / C in methanol / DMF at 20-30 °.

The compounds of the formula II are generally known. If they are not known, they can be produced by methods known per se.

The compounds of the formula II are generally reacted in an inert solvent, in the presence of an acid-binding agent, preferably an organic base such as triethylamine, dimethylaniline, pyridine or quinoin. Also the addition of an alkali or alkaline earth metal hydroxide, carbonate or bicarbonate or another salt of a weak acid

Alkali or alkaline earth metals, preferably potassium, sodium, calcium or cesium, can be favorable.

Depending on the conditions used, the reaction time is between a few minutes and 14 days, the reaction temperature is between about -30 ° and 140 °, normally between -10 ° and 90 °, in particular between about 0 ° and about 70 °.

Suitable inert solvents are e.g. Hydrocarbons such as hexane, petroleum ether, benzene, toluene or xylene; chlorinated hydrocarbons such as trichlorethylene, 1, 2-dichloroethane, carbon tetrachloride, chloroform or

Dichloromethane; Alcohols such as methanol, ethanol, isopropanol, n-propanol, n-butanol or tert-butanol; Ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran (THF) or dioxane; Glycol ethers such as ethylene glycol monomethyl or monoethyl ether (methyl glycol or ethyl glycol), ethylene glycol dimethyl ether (diglyme); Ketones such as acetone or butanone;

Amides such as acetamide, dimethylacetamide or dimethylformamide (DMF); Nitriles such as acetonitrile; Sulfoxides such as dimethyl sulfoxide (DMSO); Sulfur carbon; Carboxylic acids such as formic acid or acetic acid; Nitro compounds such as nitromethane or nitrobenzene; Esters such as ethyl acetate, water or mixtures of the solvents mentioned. It is also possible to saponify an ester of the formula I. This is expediently carried out by solvolysis or hydrogenolysis, as indicated above, for example with NaOH or KOH in dioxane-water at temperatures between 0 and 60 ° C., preferably between 10 and 40 ° C.

It is also possible for one radical R ¹ and / or R ^{2 to be converted} into another radical R ¹ and / or R ² .

In particular one can use an azido group e.g. convert to an amino group by hydrogenolysis as indicated above or an amino group by reaction with an amidinating agent such as e.g.

Dimethylpyrazolformamidinium nitrate, convert into a guanidino group.

The conversion of a cyano group into an amidino group takes place by reaction with e.g. Hydroxylamine and subsequent reduction of the N-hydroxyamidine with hydrogen in the presence of a catalyst such as e.g. Pd / C.

It is also possible to replace a conventional amino protecting group with hydrogen by removing the protective group as described above, solvolytically or hydrogenolytically, or by liberating an amino group protected by a conventional protecting group by solvolysis or hydrogenolysis.

A base of the formula I can be converted into the associated acid addition salt using an acid, for example by reacting equivalent amounts of the base and the acid in an inert solvent such as ethanol and subsequent evaporation. In particular, acids that provide physiologically acceptable salts are suitable for this implementation. Thus, inorganic acids can be used, for example sulfuric acid, nitric acid, hydrohalic acids such as hydrochloric acid or hydrobromic acid, phosphoric acids such as orthophosphoric acid, surfamic acid, and also organic acids, in particular aliphatic, alicyclic, araliphatic, aromatic or heterocyclic mono- or poly-based carbon atoms. , Sulfonic or sulfuric acids, for example formic acid, acetic acid, propionic acid, pivalic acid, diethyl acetic acid, malonic acid, succinic acid, pimeic acid, fumaric acid, maleic acid, lactic acid, tartaric acid, malic acid, citric acid, gluconic acid, Ascorbic acid, nicotinic acid, isonicotinic acid, methane or ethanesulfonic acid, ethanedisulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, naphthalene mono- and disulfonic acids, lauryl sulfuric acid. Salts with physiologically unacceptable acids, for example picrates, can be used for the isolation and / or purification of the compounds of the formula I.

On the other hand, an acid of the formula I can be converted into one of its physiologically acceptable metal or ammonium salts by reaction with a base. Suitable salts are, in particular, the sodium, potassium, magnesium, calcium and ammonium salts, and also substituted ammonium salts, e.g. B. the dimethyl, diethyl or diisopropyl ammonium salts, monoethanol, diethanol or diisopropylammonium salts, cyclohexyl, dicyclohexylammonium salts, dibenzylethylenediammonium salts, z. B. salts with arginine or lysine.

The compounds of the formula I contain one or more chiral centers and can therefore be present in racemic or in optically active form. Racemates obtained can be separated mechanically or chemically into the enantiomers by methods known per se. Diastereomers are preferably formed from the racemic mixture by reaction with an optically active release agent. Suitable release agents are e.g. optically active acids, such as the D and L forms of tartaric acid, diacetyl tartaric acid, dibenzoyl tartaric acid, mandelic acid, malic acid, lactic acid or the various optically active camphorsulfonic acids such as ß-camphorsurfonic acid. Enantiomer separation using a column filled with an optically active separating agent (e.g. dinitrobenzoylphenylglycine) is also advantageous; a suitable solvent is e.g. a mixture of hexane / isopropanol / acetonitrile, e.g. in the volume ratio 82: 15: 3.

Of course, it is also possible to obtain optically active compounds of the formula I by the methods described above by using starting materials which are already optically active. The test results of the α _v β ₃ and α _v β ₅ inhibition by some representative compounds of the formula I are summarized in Table I below. For the vitronectin binding tests are the IC ₅ o values are given, ie, the concentrations in nmol / liter which inhibit 50% of the Vitronectm binding to the corresponding isolated receptor.
