- Oxazolidinones of the formula (I) are known from WO 01/047919 and act in particular as selective inhibitors of the blood coagulation factor Xa and as anticoagulants.
- Oxazolidinones of formula (I) are selective factor Xa inhibitors and specifically inhibit only FXa.
- An antithrombotic effect of factor Xa inhibitors has been demonstrated in numerous animal models (see U. Sinha, P. Ku, J. Malinowskd, B. Yan Zhu, RM Scarborough, K.K. Marlowe, PW, Wong, P. Hua Lin, SJ Hollenbach, Antithrombotic and hemostatic capacity of factor Xa versus thrombin inhibitors in the mode of venous and arteriovenous thrombosis, European Journal of Pharmacology 2000, 395, 51-59, A. Betz, Recent Advances in Factor Xa inhibitors, Expert Opinion. Ther.
- factor Xa inhibitors can be preferably used in medicaments for the prophylaxis and / or treatment of thromboembolic disorders.
- Selective FXa inhibitors show a broad therapeutic window.
- FXa inhibitors have an antithrombotic effect in thrombosis models without, or only slightly, prolonging bleeding time (see RJ Leadly, Coagulation Factor Xa inhibition: biological background and rational, Curr Top Med Chem 2001, 1 , 151-159). An individual dosage in anticoagulation with selective FXa inhibitors is therefore not necessary.
- Pulmonary hypertension (Clinical Classification of Pulmonary Hypertension, Venice, 2003) is a progressive lung disease that may have multiple causes and lead to death if left untreated. This leads to an overload of the right heart withkherzinsuff ⁇ zienz up to the pump failure, which can lead to death.
- Defintionsmother is at a pulmonary arterial hypertension (mPAP) of> 25 mmHg at rest or> 30 mmHg during exercise (normal value ⁇ 20 mmHg).
- mPAP pulmonary arterial hypertension
- the pathophysiology of pulmonary hypertension often includes thrombosis of the pulmonary vessels.
- PAH primary pulmonary hypertension
- New combination therapies are one of the most promising future treatment options for the treatment of pulmonary arterial hypertension (Ghofrani et al., Herz 2005, 30, 296-302).
- P450 does not inhibit or inhibit CYP enzymes to a very limited extent (compare drug interactions in the combination therapy of bosentan and warfarin).
- WO 2006/045756 mentions the combination of dipyridamole with rivaroxaban for the treatment of pulmonary hypertension, but without mentioning any findings.
- dipyridamole has a variety of side effects, such as. Hypotension, cardiac arrest, cardiac arrhythmias, allergic reactions / aggravation of bronchial asthma (on tartrazine in hypersensitivity), bronchial asthma, hepatic enzyme elevation and liver failure.
- dipyridamole shows interactions with other drugs such.
- platelet aggregation inhibitors eg aspirin
- anticoagulants eg warfarin

- the enzymatic activity of human factor Xa is measured by the reaction of a FXa-specific chromogenic substrate.
- the factor Xa cleaves from the chromogenic substrate p-nitroaniline. The determinations are carried out in microtiter plates as follows.
- the control is pure DMSO.
- the chromogenic substrate 150 .mu.mol / 1 Pefachrome® FXa from Pentapharm
- the absorbance at 405 nm is determined.
- the extinctions of the test mixtures with test substance are compared with the control batches without test substance and from this the
- test substances are tested for their inhibition of other human serine proteases such as trypsin, plasmin.
- trypsin 500 mU / ml
- plasmin 3.2 nmol / l
- the enzymatic reaction is then started by addition of the corresponding specific chromogenic substrates (Chromozym Trypsin® and Chromozym Plasmin®, from Roche Diagnostics) and the extinction is determined after 20 minutes at 405 nm. All determinations are carried out at 37 ° C.
- the extinctions of the test mixtures with test substance are compared with the control samples without test substance and from this the IC 50 values are calculated.
- the anticoagulant effect of the test substances is determined in vitro in human and rabbit plasma.
- blood is taken using a 0.11 molar sodium citrate solution as a template in a mixing ratio of sodium citrate / blood 1/9.
- the blood is mixed well immediately after collection and centrifuged for 10 minutes at about 2500 g. The supernatant is pipetted off.
- the prothrombin time (PT, synonyms: thromboplastin time, quick-test) is home or in the presence of varying concentrations of test substance or the corresponding solvent using a commercial test kit (Neoplastin ® from Boehringer Man Hemoliance ® RecombiPlastin, Fa from Instrumentation Laboratory. ) certainly.
- test compounds are incubated for 3 minutes at 37 ° C with the plasma. Subsequently, coagulation is triggered by the addition of thromboplastin and the time of coagulation is determined. The concentration of test substance is determined which causes a doubling of the prothrombin time.
- the shunt is closed in the middle by a 3 cm polyethylene tube (PE 160) containing a roughened and looped nylon thread to create a thrombogenic surface.
- PE 160 polyethylene tube
- the extracorporeal circuit is maintained for 15 minutes. Then the shunt is removed and the nylon thread with the thrombus weighed immediately. The net weight of the nylon thread was determined before the start of the test.
- the Test substances are administered either intravenously via the tail vein or animals monitored by gavage prior to application of the extracorporeal circuit.
- Rat monocrotaline-induced pulmonary hypertension is a widely used animal model of pulmonary arterial hypertension.
- the pyrrolizidine alkaloid monocrotalin becomes subcutaneous
