Within the scope of the present application, the terms "isomers",

"stereoisomers", "diastereomers", "enantiomers", "chiral", "racemate" or "racemic mixture" are to be understood as follows. Compounds with the same generic formula that differ in the nature or arrangement of the bonding of their atoms or their connectivity or the spatial arrangement of the atoms in the molecule are known as isomers. Isomers which, while having the same type and manner of connectivity between their atoms, differ in the spatial arrangement of the atoms in the molecule and are not congruent are referred to as "stereoisomers". Stereoisomers that do not behave as an image and mirror image to each other are known as "diastereomers", and stereoisomers that behave as an image and mirror image to each other are known as "enantiomers". If there is an asymmetric centre or atom present (also known as a stereocentre or chiral centre), for example at a carbon atom substituted by four different substituents, the molecule is of a "chiral" nature and a pair of enantiomers is possible. An enantiomer may be characterised by the absolute configuration of its stereocentre. The absolute configuration is described using the descriptors (R) and (S), which are determined by applying the sequence rules according to Cahn, lngold and Prelog , or by describing the rotation of the plane of polarised light on interaction with the molecule which is termed dextrorotatory or levorotatory (i.e. with (+) or (-) as descriptor, accordingly). A chiral compound may be present either as an individual enantiomer or as a mixture of the corresponding enantiomers. A mixture that contains equal amounts of both enantiomers of a compound is termed a "racemate" or "racemic mixture".

According to the invention the compounds of general formula (I) are obtained by methods known per se, for example by the following methods:

(a) The preparation of a compound of general formula (I)

Any protective group used may optionally subsequently be cleaved for example by hydrolysis in an aqueous solvent, e.g. in water, isopropanol/water, tetrahydrofuran/water or dioxane/water, in the presence of an acid such as trifluoroacetic acid, hydrochloric acid or sulphuric acid or in the presence of an alkali metal base such as lithium hydroxide, sodium hydroxide or potassium hydroxide or by ether splitting, e.g. in the presence of iodotrimethylsilane, at temperatures between 0 and 100⁰C, preferably at temperatures between 10 and 50⁰C.

However, a benzyl, methoxybenzyl or benzyloxycarbonyl group is cleaved hydrogenolytically, for example, e.g. with hydrogen in the presence of a catalyst such as palladium/charcoal in a solvent such as methanol, ethanol, ethyl acetate, dimethylformamide, dimethylformamide/acetone or glacial acetic acid, optionally with the addition of an acid such as hydrochloric acid at temperatures between 0 and 50°C, but preferably at ambient temperature, and at a hydrogen pressure of 1 to 7 bar, preferably, however, 1 to 5 bar.

A methoxybenzyl group may also be cleaved in the presence of an oxidising agent such as cerium(IV)ammonium nitrate in a solvent such as methylene chloride, acetonitrile or acetonitrile/water at temperatures of between 0 and 50⁰C, but preferably at ambient temperature.

A methoxy group is expediently cleaved in the presence of boron thbromide in a solvent such as methylene chloride at temperatures between -35 and -25°C.

A 2,4-dimethoxybenzyl group is preferably cleaved in trifluoroacetic acid in the presence of anisol.

A te/t.butyl or te/t.butyloxycarbonyl group is preferably cleaved by treating with an acid such as trifluoroacetic acid or hydrochloric acid, optionally using a solvent such as methylene chloride, dioxane or ether.

A phthalyl group is preferably cleaved in the presence of hydrazine or a primary amine such as methylamine, ethylamine or n-butylamine in a solvent such as methanol, ethanol, isopropanol, toluene/water or dioxane at temperatures between 20 and 50⁰C.

An allyloxycarbonyl group is cleaved by treating with a catalytic amount of tetrakis-(thphenylphosphine)-palladium(0), preferably in a solvent such as tetrahydrofuran and preferably in the presence of an excess of a base such as morpholine or 1 ,3-dimedone at temperatures between 0 and 100⁰C, preferably at ambient temperature and under an inert gas, or by treating with a catalytic amount of tris-(thphenylphosphine)-rhodium(l)chloride in a solvent such as aqueous ethanol and optionally in the presence of a base such as 1 ,4-diazabicyclo[2.2.2]octane at temperatures between 20 and 70°C.

Compounds of general formulae (III), wherein the group B' is represented by a group of general formula (V), and (Vl) may be prepared for example analogously to K. Maekawa, J. Ohtani, Agr. Biol. Chem. 1976, 40, 791-799.

Moreover the compounds of general formula (I) obtained may be resolved into their enantiomers and/or diastereomers.

Thus, for example, the compounds of general formula I obtained which occur as racemates may be separated by methods known per se (cf. Allinger N. L. and ENeI E. L. in "Topics in Stereochemistry", Vol. 6, Wiley Interscience, 1971 ) into their optical antipodes and compounds of general formula I with at least 2 asymmetric carbon atoms may be resolved into their diastereomers on the basis of their physical-chemical differences using methods known per se, e.g. by chromatography and/or fractional crystallisation, and, if these compounds are obtained in racemic form, they may subsequently be resolved into the enantiomers as mentioned above.

The enantiomers are preferably separated by column separation on chiral phases or by recrystallisation from an optically active solvent or by reacting with an optically active substance which forms salts or derivatives such as e.g. esters or amides with the racemic compound, particularly acids and the activated derivatives or alcohols thereof, and separating the diastereomehc mixture of salts or derivatives thus obtained, e.g. on the basis of their differences in solubility, whilst the free antipodes may be released from the pure diastereomeric salts or derivatives by the action of suitable agents. Optically active acids in common use are e.g. the D- and L-forms of tartaric acid or dibenzoyltartaric acid, di-o-tolyltartaric acid, malic acid, mandelic acid, camphorsulphonic acid, glutamic acid, aspartic acid or quinic acid. An optically active alcohol may be for example (+) or (-)-menthol and an optically active acyl group in amides may be a (+)- or (-)-menthyloxycarbonyl, for example.

Furthermore, the compounds of formula I may be converted into the salts thereof, particularly for pharmaceutical use into the physiologically acceptable salts thereof with inorganic or organic acids. Acids which may be used for this purpose include for example hydrochloric acid, hydrobromic acid, sulphuric acid, methanesulphonic acid, phosphoric acid, fumaric acid, succinic acid, lactic acid, citric acid, tartaric acid or maleic acid.

Moreover, if the new compounds of formula I contain a carboxy group, they may subsequently, if desired, be converted into the salts thereof with inorganic or organic bases, particularly for pharmaceutical use into the physiologically acceptable salts thereof. Suitable bases for this purpose include for example sodium hydroxide, potassium hydroxide, cyclohexylamine, ethanolamine, diethanolamine and triethanolamine.

As already mentioned, the compounds of general formula I as well as the tautomers, the enantiomers, the diastereomers and the physiologically acceptable salts thereof have valuable pharmacological properties, particularly an antithrombotic activity, which is preferably based on an effect on thrombin or factor Xa, for example on a thrombin-inhibiting or factor Xa-inhibiting activity, on a prolonging effect on the aPTT time and on an inhibiting effect on related serine proteases such as e.g. urokinase, factor Vila, factor IX, factor Xl and factor XII.

The compounds listed in the experimental section may be investigated for their effect on the inhibition of factor Xa as follows:

Method:

Enzyme-kinetic measurement with chromogenic substrate. The quantity of p- nitroaniline (pNA) released from the colourless chromogenic substrate by human factor Xa is determined photometrically at 405 nm. It is proportional to the activity of the enzyme used. The inhibition of the enzyme activity by the test substance (in relation to the solvent control) is determined at various concentrations of test substance and from this the IC₅O is calculated, as the concentration which inhibits the factor Xa used by 50 %.

Material: Ths(hydroxymethyl)-aminomethane buffer (100 mMol) and sodium chloride (150 mMol), pH 8.0 plus 1 mg/ml Human Albumin Fraction V, protease-free.

Factor Xa (Calbiochem), spec, activity: 217 IU/mg, final concentration: 7 IU/ml for each reaction mixture

Substrate S 2765 (Chromogenix), final concentration: 0.3 mM/l (1 KM) for each reaction mixture Test substance: final concentration 100, 30, 10, 3, 1 , 0.3, 0.1 , 0.03, 0.01 , 0.003, 0.001 μMol/l

Procedure: 10 μl of a 23.5-times concentrated starting solution of the test substance or solvent (control), 175 μl of TRIS/HSA buffer and 25 μl of a 65.8 U/L Factor Xa working solution are incubated for 10 minutes at 37°C. After the addition of 25 μl of S 2765 working solution (2.82 mMol/l) the sample is measured in a photometer (SpectraMax 250) at 405 nm for 600 seconds at 37°C.

Evaluation:

1. Determining the maximum increase (deltaOD/minutes) over 21 measuring points.

2. Determining the % inhibition based on the solvent control.

3. Plotting a dosage/activity curve (% inhibition vs substance concentration).

4. Determining the IC₅O by interpolating the X-value (substance concentration) of the dosage/activity curve at Y = 50 % inhibition.

All the compounds tested had an IC₅O value of less than 100 μmol/L.

The compounds prepared according to the invention are generally well tolerated.

In view of their pharmacological properties the new compounds and the physiologically acceptable salts thereof are suitable for the prevention and treatment of venous and arterial thrombotic diseases, such as for example the prevention and treatment of deep leg vein thrombosis, thrombophlebitis, for preventing reocclusions after bypass operations or angioplasty (PT(C)A), and occlusion in peripheral arterial diseases, and for preventing and treating pulmonary embolism, disseminated intravascular coagulation and severe sepsis, for preventing and treating DVT in patients with exacerbation of COPD, for treating ulcerative colitis, for treating and preventing coronary thrombosis, for preventing stroke and the occlusion of shunts.

In addition, the compounds according to the invention are suitable for antithrombotic support in thrombolytic treatment, such as for example with alteplase, reteplase, tenecteplase, staphylokinase or streptokinase, for preventing long-term restenosis after PT(C)A, for the prevention and treatment of ischaemic events in patients with all forms of coronary heart disease, for preventing metastasis and the growth of tumours and inflammatory processes, e.g. in the treatment of pulmonary fibrosis, for preventing and treating rheumatoid arthritis, for preventing and treating fibrin-dependent tissue adhesions and/or the formation of scar tissue and for promoting wound healing processes.

The compounds specified may also be used as anticoagulants in connection with the preparation, storage, fractionation or use of whole blood or in invasive therapies, e.g. for coating prostheses, artificial heart valves and catheters for reducing the risk of thrombosis.

In view of their pharmacological properties the new compounds and the physiologically acceptable salts thereof are also suitable for treating Alzheimer's and Parkinson^'s disease. One rationale for this can be seen for example in the following findings, from which it can be concluded that thrombin inhibitors or factor Xa inhibitors, by inhibiting thrombin formation or activity, could be valuable drugs for treating Alzheimer's and Parkinson^'s disease. Clinical and experimental studies indicate that neurotoxic mechanisms, for example the inflammation that accompanies the activation of proteases of the clotting cascade, are involved in the dying off of neurones following brain damage. Various studies indicate an involvement of thrombin in neurodegenerative processes, e.g. following a stroke, repeated bypass operations or traumatic brain injury. An increased thrombin activity was able to be detected for example some days after peripoheral nerve damage. It was also shown that thrombin causes neurite retraction and glia proliferation, and apoptosis in primary cultures of neurones and neuroblastoma cells (for an overview see: Neurobiol. Aging, 2004, 25(6), 783-793). In addition, various in vitro studies on the brains of patients with Alzheimer's disease indicate that thrombin plays a part in the pathogenesis of this disease (Neurosci. Lett., 1992, 146, 152-54). An accumulation of immunoreactive thrombin has been detected in neurite plaques in the brains of Alzheimer's patients. It was demonstrated in vitro that thrombin also plays a part in the regulation and stimulation of the production of Amyloid Precursor Protein (APP) as well as in the cleaving of APP into fragments which can be detected in the amyloid plaques in the brains of Alzheimer's patients. It has also been shown that thrombin-induced microglial activation in vivo leads to the degeneration of nigral dopaminergic neurones. These findings lead one to conclude that microglial activation, triggered by endogenous substance(s) such as thrombin, for example, are involved in the neuropathological process of the cell death of dopaminergic neurones, such as occurs in patients with Parkinson's disease (J. Neurosci., 2003, 23, 5877-86).

The new compounds and the physiologically acceptable salts thereof can also be used for the prevention and treatment of arterial vascular diseases in combination therapy with lipid-lowering active substances such as HMG-CoA reductase inhibitors and vasodilators, particularly ACE inhibitors, angiotensin Il antagonists, renin inhibitors, β-receptor antagonists, α-receptor antagonists, diuretics, Ca-channel blockers, or stimulators of soluble guanylate cyclase.

By increasing the antithrombotic activity the new compounds and the physiologically acceptable salts thereof can also be used in combination therapy with other anticoagulants such as, for example, unfractionated heparin, low-molecular heparin, fondaparinux or direct thrombin inhibitors, for example recombinant hirudine or "active-site" thrombin inhibitors.

The new compounds and the physiologically acceptable salts thereof may be used therapeutically in conjunction with acetylsalicylic acid, with inhibitors of platelet aggregation such as fibrinogen receptor antagonists (e.g. abciximab, eptifibatide, tirofiban, roxifiban), with physiological activators and inhibitors of the clotting system and the recombinant analogues thereof (e.g. Protein C, TFPI, antithrombin), with inhibitors of ADP-induced aggregation (e.g. clopidogrel, prasugrel, ticlopidine), with P₂T receptor antagonists (e.g. cangrelor) or with combined thromboxane receptor antagonists/synthetase inhibitors (e.g. terbogrel).

The dosage required to achieve such an effect is appropriately 0.01 to 3 mg/kg, preferably 0.03 to 1.0 mg/kg by intravenous route, and 0.03 to 30 mg/kg, preferably 0.1 to 10 mg/kg by oral route, in each case administered 1 to 4 times a day.

For this purpose, the compounds of formula I prepared according to the invention may be formulated, optionally together with other active substances, with one or more inert conventional carriers and/or diluents, e.g. with corn starch, lactose, glucose, microcrystalline cellulose, magnesium stearate, polyvinylpyrrolidone, citric acid, tartaric acid, water, water/ethanol, water/glycerol, water/sorbitol, water/polyethylene glycol, propylene glycol, cetylstearyl alcohol, carboxymethylcellulose or fatty substances such as hard fat or suitable mixtures thereof, to produce conventional galenic preparations such as plain or coated tablets, capsules, powders, suspensions or suppositories.

The new compounds and the physiologically acceptable salts thereof may be used therapeutically in conjunction with acetylsalicylic acid, with inhibitors of platelet aggregation such as fibrinogen receptor antagonists (e.g. abciximab, eptifibatide, tirofiban, roxifiban), with physiological activators and inhibitors of the clotting system and the recombinant analogues thereof (e.g. Protein C, TFPI, antithrombin), with inhibitors of ADP-induced aggregation (e.g. clopidogrel, ticlopidine), with P₂T receptor antagonists (e.g. cangrelor) or with combined thromboxane receptor antagonists/synthetase inhibitors (e.g. terbogrel).
