The present invention relates to the field of blood coagulation. In particular, the present invention relates to new oxazolidinone derivatives, processes for their preparation and their use as active ingredients in medicaments.
Blood coagulation is a protective mechanism of the organism, with the help of which defects in the vessel wall can be "sealed" quickly and reliably. In this way, blood loss can be avoided or minimized. Hemostasis after vascular injury occurs essentially through the coagulation system, in which an enzymatic cascade of complex reactions of plasma proteins is triggered. Numerous blood coagulation factors are involved, each of which, when activated, converts the next inactive precursor into its active form. At the end of the cascade there is the conversion of the soluble fibrinogen into the insoluble fibrin, so that a blood clot occurs. In blood coagulation, a distinction is traditionally made between the intrinsic and extrinsic systems, which lead to a final common reaction path. The factor Xa, which is formed from the proenzyme factor X, plays a key role here, since it connects both clotting pathways. The activated serine protease Xa cleaves prothrombin to thrombin. The thrombin in turn in turn cleaves fibrinogen to fibrin, a fibrous-gelatinous coagulant. In addition, thrombin is a potent trigger for platelet aggregation, which also makes a significant contribution to hemostasis.
The maintenance of normal hemostasis - between bleeding and thrombosis - is subject to a complex regulatory mechanism. The uncontrolled activation of the coagulation system or a defective inhibition of the activation processes can cause the formation of local thrombi or emboli in vessels (arteries, veins, lymphatic vessels) or cardiac cavities. This can lead to serious diseases such as heart attack, angina pectoris (including unstable angina), reocclusions and restenosis after angioplasty or aortocoronary bypass, stroke, transient ischemic attacks, peripheral arterial disease, pulmonary embolism or deep venous thrombosis; in the following, these diseases are also referred to collectively as thromboembolic diseases. In addition, hypercoagulability - systemic - in disseminated coagulopathy can lead to disseminated intravascular coagulation.
These thromboembolic disorders are the most common cause of morbidity and mortality in most industrialized countries (Pschyrembel, clinical dictionary, 257th edition, 1994, Walter de Gruyter Verlag, page 199 ff., Keyword "blood coagulation"; Römpp Lexikon Chemie, version 1.5, 1998, Georg Thieme Verlag Stuttgart, keyword "blood coagulation"; Lubert Stryer, biochemistry, spectrum of science Verlagsgesellschaft mbH Heidelberg, 1990, pages 259 ff.).
The anticoagulants known from the prior art, ie substances for inhibiting or preventing blood clotting, have various, often serious, disadvantages. An efficient treatment method or prophylaxis of thromboembolic diseases therefore proves to be very difficult and unsatisfactory in practice.
On the one hand, heparin is used for the therapy and prophylaxis of thromboembolic diseases, which is administered parenterally or subcutaneously. Because of the more favorable pharmacokinetic properties, low molecular weight heparin is increasingly preferred today; however, this also does not prevent the known disadvantages described below, which exist in the treatment with heparin. For example, heparin is orally ineffective and has a comparatively short half-life. Since heparin inhibits several factors in the blood coagulation cascade at the same time, it has an unselective effect. In addition, there is a high risk of bleeding, in particular brain bleeding and bleeding in the gastrointestinal tract can occur, and thrombopenia, alopecia medicomentosa or osteoporosis can occur (Pschyrembel, Klinisches Wörterbuch, 257. Edition, 1994, Walter de Gruyter Verlag, page 610, keyword "Heparin"; Römpp Lexikon Chemie, Version 1.5, 1998, Georg Thieme Verlag Stuttgart, keyword "Heparin").
A second class of anticoagulants are the vitamin K antagonists. These include, for example, 1,3-indanediones, but especially compounds such as warfarin, phenprocoumon, dicumarol and other coumarin derivatives, which are non-selective in the synthesis of various products of certain vitamin K-dependent coagulation factors inhibit in the liver. Due to the mechanism of action, the effect is only very slow (latency until the onset of action 36 to 48 hours). Although the compounds can be administered orally, due to the high risk of bleeding and the narrow therapeutic index, complex individual adjustment and observation of the patient is necessary. In addition, other side effects such as gastrointestinal disorders, hair loss and skin necrosis are described (Pschyrembel, Klinisches Wörterbuch, 257. Edition, 1994, Walter de Gruyter Verlag, page 292 ff., Keyword "coumarin derivatives"; Ullmann's Encyclopedia of Industrial Chemistry, 5th edition, VCH Publishing Company, Weinheim, 1985 - 1996, keyword "Vitamin K").
A new therapeutic approach for the treatment and prophylaxis of thromboembolic disorders has recently been described. The aim of this new therapeutic approach is to inhibit factor Xa (cf. WO-A-99/37304; WO-A-99/06371; J. Hauptmann, J. Sturzbecher, Thrombosis Research<b>1999,</b><i>93</i>, 203; F. Al-Obeidi, JA Ostrem, Factor Xa inhibitors by classical and combinatorial chemistry, DDT<b>1998,</b><i>3</i>, 223; F. Al-Obeidi, JA Ostrem, Factor Xa inhibitors, Exp. Opin. Ther. Patents<b>1999,</b><i>9</i>, 931; B. Kaiser, Thrombin and factor Xa inhibitors, Drugs of the Future<b>1998</b>, <i>23</i>, 423; A. Uzan, Antithrombotic Agents, Emerging Drugs<b>1998</b>, <i>3</i>, 189; B.-Y. Zhu, RM Scarborough, Curr. Opin. Card. Pulm. Ren. Inv. Drugs<b>1999,</b><i>1 (1)</i>, 63). It has been shown that various compounds, both peptide and non-peptide, are effective as factor Xa inhibitors in animal models.
The object of the present invention is now to provide new substances for combating diseases which have a wide therapeutic range.
They are said to be particularly suitable for more efficient prophylaxis and / or treatment of thromboembolic diseases and to avoid, at least in part, the disadvantages of the prior art described above, the term "thromboembolic diseases" meaning, in the context of the present invention, particularly serious diseases such as heart attacks Angina pectoris (including unstable angina), Reocclusions and restenosis after angioplasty or aortocoronary bypass, stroke, transient ischemic attacks, peripheral arterial disease, pulmonary embolism or deep venous thrombosis are understood.
Another object of the present invention is to provide new anticoagulants which inhibit the blood clotting factor Xa with increased selectivity and which are intended to avoid, at least in part, the problems of the therapy methods known from the prior art for thromboembolic disorders.

So far, oxazolidinones have essentially only been described as antibiotics, occasionally also as MAO inhibitors and fibrinogen antagonists (overview: Riedl, B., Endermann, R., Exp. Opin. Ther. Patents <b>1999</b>, <i>9</i> (5), 625), where a small 5- [acylaminomethyl] group (preferably 5- [acetylaminomethyl]) appears to be essential for the antibacterial effect.
Substituted aryl- and heteroarylphenyloxazolidinones, in which a mono- or polysubstituted phenyl radical may be bound to the N atom of the oxazolidinone ring and which may have an unsubstituted N-methyl-2-thiophenecarboxamide radical in the 5-position of the oxazolidinone ring, and theirs Use as antibacterial substances are known from US Pat. Nos. 5,929,248, 5,801,246, 5,756,732, 5,654,435, 5,654 428 and US-A-5 565 571.
In addition, benzamidine-containing oxazolidinones are known as synthetic intermediates in the synthesis of factor Xa inhibitors or fibrinogen antagonists (WO-A-99/31092, EP-A-623615).
Depending on the substitution pattern, the compounds of the general formula (I) according to the invention can exist in stereoisomeric forms which either behave like image and mirror image (enantiomers) or do not behave like image and mirror image (diastereomers). The invention relates both to the enantiomers or diastereomers and to their respective mixtures. Like the diastereomers, the racemic forms can be separated into the stereoisomerically uniform constituents in a known manner.
Furthermore, certain compounds of the general formula (I) can exist in tautomeric forms. This is known to those skilled in the art and such compounds are also within the scope of the invention.
Physiologically acceptable, ie pharmaceutically acceptable salts can be salts of the compounds according to the invention with inorganic or organic acids. Salts with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid or sulfuric acid are preferred, or salts with organic carboxylic or sulfonic acids such as acetic acid, trifluoroacetic acid, propionic acid, maleic acid, fumaric acid, malic acid, citric acid, tartaric acid, lactic acid, benzoic acid or methanesulfonic acid, ethanesulfonic acid , Benzenesulfonic acid, toluenesulfonic acid or naphthalenedisulfonic acid.
As pharmaceutically acceptable salts there can also be mentioned salts with conventional bases, such as, for example, alkali metal salts (for example sodium or potassium salts), alkaline earth metal salts (for example calcium or magnesium salts) or ammonium salts, derived from ammonia or organic amines such as, for example, diethylamine, triethylamine, ethyldiisopropylamine, procaine , Dibenzylamine, N-methylmorpholine, dihydroabietylamine or methylpiperidine.
As <u>"Hydrates"</u> Those forms of the compounds of the above general formula (I) are designated according to the invention which, in the solid or liquid state, form a molecular compound (solvate) by hydration with water. In the hydrates, the water molecules are attached in a secondary manner due to intermolecular forces, especially hydrogen bonds. Solid hydrates contain water as so-called crystal water in stoichiometric proportions, whereby the water molecules do not have to be equivalent in terms of their binding state. Examples of hydrates are sesquihydrates, monohydrates, dihydrates or trihydrates. Equally, the hydrates of salts of the compounds according to the invention can also be used.
As <u>"Prodrugs"</u> According to the invention, those forms of the compounds of the above general formula (I) are referred to which can themselves be biologically active or inactive, but which can be converted into the corresponding biologically active form (for example metabolically, solvolytically or in another way).

<u>Examples</u>
A <u>Assessment of physiological effectiveness</u>
1. <u>General test methods</u>
The particularly advantageous biological properties of the compounds according to the invention can be determined by the following methods.
<u>a) Test description (in vitro)</u>
a.1) Measurement of factor Xa inhibition
The enzymatic activity of human factor Xa (FXa) was measured via the conversion of a chromogenic substrate specific for the FXa. The factor Xa cleaves p-nitroaniline from the chromogenic substrate. The determinations were carried out in microtiter plates as follows.
The test substances were dissolved in different concentrations in DMSO and for 10 minutes with human FXa (0.5 nmol / l dissolved in 50 mmol / l Tris buffer [C, C, C-Tris (hydroxymethyl) aminomethane], 150 mmol / l NaCl, 0.1% BSA (bovine serum albumine), pH = 8.3) at 25 ° C. Pure DMSO serves as a control. The chromogenic substrate (150 μmol / l Pefachrome® FXa from Pentapharm) was then added. After an incubation period of 20 minutes at 25 ° C., the absorbance at 405 nm was determined. The extinctions of the test batches with test substance were compared with the control batches without test substance and the IC was derived from them<sub>50</sub>-Values calculated.
a.2) Determination of selectivity
To detect selective FXa inhibition, the test substances were examined for their inhibition of other human serine proteases such as thrombin, trypsin, plasmin. To determine the enzymatic activity of thrombin (75 mU / ml), trypsin (500 mU / ml) and plasmin (3.2 nmol / l), these enzymes were placed in Tris buffer (100 mmol / l, 20 mmol / l CaCl<sub>2</sub>, pH = 8.0) and incubated for 10 minutes with test substance or solvent. The enzymatic reaction was then started by adding the corresponding specific chromogenic substrates (Chromozym Thrombin® from Boehringer Mannheim, Chromozym Trypsin® from Boehringer Mannheim, Chromozym Plasmin® from Boehringer Mannheim) and the extinction after 20 minutes at 405 nm certainly. All determinations were carried out at 37 ° C. The extinctions of the test batches with the test substance were compared with the control samples without the test substance and the IC<sub>50</sub>-Values calculated.
a.3) Determination of the anticoagulant effect
The anticoagulant effect of the test substances was determined in vitro in human plasma. Human blood was drawn using a 0.11 molar sodium citrate solution as a template in a sodium citrate / blood mixing ratio of 1/9. The blood was mixed well immediately after collection and centrifuged at about 2000 g for 10 minutes. The supernatant was pipetted off. The prothrombin time (PT, synonyms: thromboplastin time, quick test) was determined in the presence of varying concentrations of test substance or the corresponding solvent using a commercially available test kit (Neoplastin® from Boehringer Mannheim). The test compounds were incubated with the plasma at 37 ° C. for 10 minutes. The coagulation was then triggered by adding thromboplastin and the time at which the coagulation started was determined. The concentration of test substance that doubled the prothrombin time was determined.
<u>b) Determination of the antithrombotic effect (in vivo)</u>
<u>b.1)</u> Arteriovenous shunt model (rat)
Fasted male rats (strain: HSD CPB: WU) weighing 200-250 g were anesthetized with a Rompun / Ketavet solution (12 mg / kg / 50 mg / kg). Thrombus formation was carried out in an arteriovenous shunt based on the method described by Christopher N. Berry et al., Br. J. Pharmacol. (1994), 113, 1209-1214 triggered the method described. For this purpose, the left jugular vein and the right carotid artery were dissected. An extracorporeal shunt was placed between the two vessels using a 10 cm long polyethylene tube (PE 60). The middle of this polyethylene tube was bound in a further 3 cm long polyethylene tube (PE 160), which contained a roughened and looped nylon thread to create a thrombogenic surface. The extracorporeal circulation was maintained for 15 minutes. The shunt was then removed and the nylon thread with the thrombus immediately weighed. The empty weight of the nylon thread had been determined before the start of the test. Before the extracorporeal circulation was established, the test substances were administered either intravenously via the tail vein or orally to animals that were awake.

b.2) Arterial thrombosis model (rat)
Male fasting rats (strain: HSD CPB: WU) were anesthetized as described above. The rats weighed approximately 200 g on average. The left carotid artery was dissected (approx. 2 cm). The formation of an arterial thrombus was caused by mechanical vascular injury based on that of K. Meng et al., Naunyn-Schmiedeberg's Arch. Pharmacol. (1977), 301, 115-119. For this purpose, the freely prepared carotid artery was disconnected from the blood flow, cooled in a metal channel to -12 ° C for 2 minutes and simultaneously compressed with a weight of 200 g to standardize the thrombus size. The blood flow was then additionally reduced by a clip placed around the carotid artery distal from the injured vascular section. The proximal clamp was removed, the wound closed and opened again after 4 hours in order to remove the injured section of the vessel. The vascular section was opened longitudinally and the thrombus removed from the injured vascular section. The wet weight of the thrombi was determined immediately. At the beginning of the test, the test substances were either administered intravenously via the tail vein or orally by means of a pharyngeal tube to awake animals.
