carboxyl, alkoxycarbonyl groups or halogen atoms;

n denotes 1 or 2 and m denotes an integer between O and 4, as well as hydrates, solvates and physiologically tolerated salts thereof. The invention also concerns the optically active forms, racemates and diastereomer mixtures of these compounds.

The invention also concerns processes for the production of the above-mentioned compounds, pharmaceutical preparations which contain such compounds as well as the use of these compounds for the production of pharmaceutical preparations.

The cyclic guanidines of the general formula I, their solvates and salts intervene in the process of blood -coagulation by the reversible inhibition of factor Xa and thus prevent the formation of hyaline thrombi. They can therefore be used to treat and prevent diseases such as thrombosis, apoplexy, cardiac infarction, inflammations and arteriosclerosis.

Factor Xa is a serine protease of the coagulation system which catalyses the proteolytic conversion of prothrombin into thrombin. Thrombin, as the last enzyme of the coagulation cascade, on the one hand cleaves fibrinogen to fibrin which becomes an insoluble gel after cross-linking by means of factor XIIIa and forms the matrix for a thrombus; on the other hand it activates platelet aggregation by proteolysis of its receptor on the blood platelets and in this manner also contributes to thrombus formation. When a blood vessel is damaged these processes are necessary to stop bleeding. Under normal circumstances no measurable thrombin concentrations are present in blood plasma. An increase in the thrombin concentration can lead to the formation of thrombi and hence to thromboembolic diseases which occur very frequently above all in industrial countries. The formation of thrombin can be prevented by inhibition of factor Xa.

It was recently reported that amidinoarylpropionic acid derivatives such as (+)-(2S)-2-[4-[[(3S)-1-acetimidoyl-3-pyrrolidinyl]oxy]phenyl]-3-(7-amidino-2-naphthyl]-propionic acid hydrochloride pentahydrate (DX-9065a;

sodium borohydride in inert solvents such as ethanol, tetrahydrofuran or dioxane.

Certain compounds of the general formula I can be subsequently converted into other compounds of the general formula I.

This relates to compounds of the general formula I which carry one or several carboxylic acid ester functions in one or several fragments of Rl-R3, A or Z. These can be converted into compounds of the general formula I with free carboxyl groups by standard methods such as e.g. by aqueous alkaline hydrolysis or by treatment with trimethylsilyl iodide at temperatures between 0~C and the boiling point of the solvent, preferably at room temperature in inert solvents such as methylene chloride or by enzymatic hydrolysis for example in the presence of an esterase.

This also relates to compounds of the general formula I
in which the fragment A contains an allyloxycarbonyl group. The free carboxylic acid is obtained by transition metal-catalysed cleavage for example by palladium-catalysed allyl cleavage in an inert solvent such as tetrahydrofuran or dioxane in the presence of a nucleophile such as e.g. 5,5-dimethyl-cyclohexane-1,3-dione or piperidine at temperatures between 0 and 50~C
preferably at room temperature.

This also relates to compounds of the general formula I
in which one or several of the substituents R1-R3 contains one or several benzyloxy groups. In this process the benzyl group is replaced by a hydrogen atom by catalytic hydrogenation in the presence of a catalyst, preferably palladium on carbon. The benzyl group can also be removed by reaction with a strong acid such as trifluoroacetic acid in the presence of mesitylene, anisole or thioanisole at temperatures between 0 and 50~C, preferably at room temperature or by treatment with Lewis acids such as BF3 etherate in an inert solvent such as toluene, acetonitrile, diethyl ether or tetrahydrofuran at temperatures between 0~C and the boiling point of the solvent, preferably between room temperature and the boiling point of the solvent or by treatment with trimethylsilyl iodide at temperatures between 0~C and the boiling point of the solvent, preferably at room temperature in inert solvents such as diethyl ether, tetrahydrofuran, methylene chloride or chloroform.

This also relates to compounds of the general formula I
in which the group Z denotes a 2-pyrrolidinyl residue allyloxycarbonyl-substituted on the nitrogen or a 3-pyrrolidinyl residue allyloxycarbonyl-substituted on the nitrogen or a 4-piperidinyl residue allyloxycarbonyl-substituted on the nitrogen. The corresponding free amine, the N-allyl-substituted amine or the N-(1-[5,5-dimethyl-3-oxo-cyclohex-1-enyl])-substituted amine can be obtained depending on the choice of the nucleophile or of the reaction temperature by palladium-catalysed reactions in an inert solvent such as tetrahydrofuran or dioxane in the presence of a nucleophile such as 5,5-dimethyl-cyclohexane-1,3-dione, tributyltin hydride, diethyl malonate or piperidine.

This also relates to compounds of the general formula I
in which the group Z denotes a 2-pyrrolidinyl residue or a 3-pyrrolidinyl residue or a 4-piperidinyl residue. The corresponding N-iminoalkyl-substituted or N-iminoaryl-substituted derivatives of the respective starting compound can be obtained by reaction with aliphatic or aromatic imidic acid ester-hydrochlorides in an inert solvent such as tetrahydrofuran, diethyl ether, ethanol, dimethylformamide or dioxane in the presence of an auxiliary base such as triethylamine, diisopropyl-ethylamine or N-methylmorpholine.

Example 26:

Description of the pharmacological experiments Isolation of plasma 9 parts fresh blood from healthy donors are mixed with one part sodium citrate solution (0.11 mol/l) and centrifuged at ca. 3000 rpm for 10 min at room temperature. The plasma is removed by pipette and can be stored for ca. 8 h at room temperature.

Activated ~artial thromboplastin time (APTT) 100 ~1 citrate plasma and 100 ~1 APTT reagent (Diagnostica Stago/ Boehringer Mannheim GmbH; contains cephalin lyophilisate with a microcrystalline kieselguhr activator) are incubated for 3 min at 37~C in a ball coagulometer (KC10 from the Amelung Company) together with 10 ~1 dimethylsulfoxide (DMS0) or 10 ~1 of a solution of the active substance in DMSO. A stopwatch is started when 100 ~1 0.025 M calcium chloride solution is added and the time point at which coagulation starts is determined. In the control measurements the APTT is ca.
28-35 seconds and is increased by the active substances.
The experiment was stopped after 5 minutes if no coagulation occurred (>300).

The measured APTT times in seconds are stated in table 1 as a difference to the control. The concentrations of the active substances in the final volumes were 100 ~M
(APTT100), 10 ~M (APTT10), 1 ~M (APTTl).

Thrombin time 200 ~1 citrate plasma is incubated for 2 min at 37~C in a ball coagulometer (KC10 from the Amelung Company). 10 ~1 dimethylsulfoxide (DMS0) or a solution of the active substance in DMS0 is added to 190 ~1 preheated thrombin reagent (Boehringer Mannheim, GmbH; contains ca. 3 U/ml horse thrombin and 0.0125 M Ca++). A stopwatch is started when this 200 ~l solution has been added to the plasma and the time point at which coagulation starts is determined. In the control measurements the thrombin time is ca. 24 seconds and is increased by the active substances. If no coagulation occurred in the measurements after 5 minutes the experiment was stopped (>300)~

The measured thrombin times in seconds are stated in table 1 as a difference to the control. The concentration of the active substances in the final volume was 500 ~M (TT500).

Inhibition constants The kinetic measurements were carried out in 0.2 M
sodium chloride and 0.5 % polyethylene glycol 6000 containing 0.1 M phosphate buffer (preparation see below) at pH 7.5 and 25~C in polystyrene semimicro-cuvettes in a total volume of 1 ml. The reactions were started by adding enzyme to preincubated solutions which either contained dimethylsulfoxide (control) or solutions of the test substance in DMS0 (inhibitor stock solutions: 10 mM in DMS0). The increase in absorbance at 405 nm caused by the release of 4-nitroaniline from the substrate was monitored photometrically for a time period of 12 min. Measurement points (time versus absorbance) were determined at intervals of 20 sec. and these data were stored by computer The inhibition constants Ki were determined as follows:
rates Vo (change in absorbance per second; measurements without inhibitor) and Vi (change in absorbance per second; measurements with inhibitor) were determined by linear regression using only the measurement points in which the substrate concentration had been reduced by less than 15 %. From one measurement series (constant inhibitor concentration, variable substrate concentrations) Km~ and VmaX were determined by a non-linear fit to the equation Vmax * [S]
V ____________ [S] + Km From the total series of measurements with 16 sets of data (measurements at 4 different substrate concentrations and each with 4 different inhibitor concentrations) the Ki value was determined by non-linear regression from the equation Vmax * [S]
V _________ __ Km * (1 + [S] /Ki) + [S]

in which VMax denotes the maximum rate in the absence of an inhibitor, KM denotes the Michaelis constant and [S]
denotes the substrate concentration.

The r.easured Ki values in [~M] are ~tated in table 1.
The entry Ki = 999 means that the respective enzyme is not inhibited.

FXa:

Stock solution: 990 ~l phosphate buffer solution (preparation see below) was admixed with 10 ~l human factor Xa (Boehringer Mannheim GmbH; 10 U; suspension) and stored on ice for a maximum of 4 hours. For the measurement 850 ,ul phosphate buffer containing 100 ,ul substrate [N-methoxycarbonyl-(D)-norleucyl-glycyl-(L)-arginine-4-nitroaniline acetate; chromozyme X;
Boehringer Mannheim GmbH; substrate concentrations used 800, 600, 400 and 200 ,uM; KM 400 ,(bM] and 25 ,~L1 inhibitor solution or 25 ,~L1 DMSO (control) are incubated in a photometer (25~C). The reaction is started by addition of 25 ,~1 stock solution.

Preparation of the 0.1 M phosphate buffer solution lPH
7.5, 0.2 M NaCl):

8.90 g Na2HPO4 ~ 2 H20, 5.84 g NaCl and 2.50 g polyethylene g1YCO1 6000 are dissolved in 400 ml distilled water and filled up with distilled water to a total volume of 500 ml (solution I). 1. 36 g KH2PO4, 1.17 g NaCl and 0. 50 g polyethylene glycol 6000 are dissolved in 80 ml distilled water and filled up with distilled water to a total volume of 100 ml (solution II). Then an amount of solution II (ca. 85 ml) is added to solution I until the pH value is 7. 5. The buffer solution is freshly prepared every time (can be stored for a maximum of 10 days when stored in a refrigerator at 4~C).
