In the reactions described hereinbefore, any reactive groups ( present such as hydroxy, carboxy, amino, alkylamino, imino or amidino groups may be protected during the reaction by means of conventional protecting groups which are cleaved again after the reaction.

For example, the protecting group for a hydroxy group may be a trimethylsilyl, acetyl, benzoyl, tert.butyl, trityl, benzyl or tetrahydropyranyl group, the protecting group for a carboxyl group may be a trimethylsilyl, methyl, ethyl, tert.butyl, benzyl or tetrahydropyranyl group, the protecting group for an amidino group optionally ~197789 substituted by an alkyl group may be a benzyloxycarbonyl group and the protecting group for an amino, alkylamino or imino group may be a formyl, acetyl, trifluoroacetyl, ethoxycarbonyl, tert.butoxycarbonyl, benzyloxycarbonyl, benzyl, methoxybenzyl or 2,4-dimethoxybenzyl group, and additionally a methyl group may be used as a protecting group for an imino group and a phthalyl group may be used as a protecting group for an amino group.

The optional subsequent cleaving of a protecting group used may, for example, be carried out hydrolytically in an aqueous solution, eg. in water, isopropanol/water, acetic acid/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 sodium hydroxide or potassium hydroxide, or by ether cleavage, eg. in the presence of iodotrimethylsilane, at temperatures between 0 and 120 C,!preferably at temperatures between 10 and 100 C.

However, a benzyl, methoxybenzyl or benzyloxycarbonyl group ~ may for example be cleaved hydrogenolytically, eg. using hydrogen in the presence of a catalyst such as palladium/charcoal, in a solvent such as methanol, ethanol, ethyl acetate or glacial acetic acid, optionally with the addition of an acid such as hydrochloric acid, at temperatures between 0 and 100 C, but preferably at temperatures between 20 and 60 C, under a hydrogen pressure of 1 to 7 bar, preferably 3 to 5 bar.

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.

Furthermore, the compounds of general formula I obtained may be resolved into their enantiomers and/or diastereomers as mentioned hereinbefore. Thus, for example, cis/trans mixtures may be resolved into their cis and trans isomers, and compounds having at least one optically active carbon atom may be resolved into their enantiomers.

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

The separation of enantiomers is preferably effected by column separation on chiral phases or by recrystallisation from an optically active solvent or by reacting with an optically active substance .(especially an acid, activated acid derivative or an alcohol thereof), which forms salts or derivatives such as esters or amides with the racemic compound, and separation of the diastereomeric salt mixture or derivative thus obtained, e.g. on the basis of their different solubilities, whilst the free antipodes may be released from the pure diastereomeric salts or derivatives by the action of suitable agents. Particularly common, optically active acids include, for example, the D- and L-forms of tartaric acid or dibenzoyltartaric acid, di-o-tolyl tartaric acid, malic acid, mandelic acid, camphorsulphonic acid, glutamic acid, aspartic acid or quinic acid. Examples of optically active alcohols include for example (+)- or (-)-menthol and examples of optically active acyl groups in amides include for example (+)- or (-)-menthyloxycarbonyl.

Moreover, the compounds of formula I obtained may be converted into the salts thereof, particularly for pharmaceutical use into the physiologically acceptable salts thereof with inorganic or organic acids. Examples of suitable acids include hydrochloric acid, hydrobromic acid, sulphuric acid, phosphoric acid, fumaric acid, succinic acid, lactic acid, citric acid, tartaric acid or maleic acid.

Furthermore, if the new compounds of formula I obtained contain a carboxyl group, they may subsequently, if desired, be converted into the salts thereof with inorganic or organic <i97789 bases, more particularly for pharmaceutical use into the physiologically acceptable salts thereof. Suitable bases for this purpose include, for example, sodium hydroxide, potassium hydroxide, arginine, cyclohexylamine, ethanolamine, diethanolamine and triethanolamine.

The compounds used as starting materials are known from the literature in some cases or may be obtained by methods known from the literature (see the Examples).

As already mentioned, the new cyclic urea derivatives of general formula I and the salts thereof, particularly the physiologically acceptable salts thereof with inorganic or organic acids or bases, have valuable properties. Thus, the new compounds of general fonnula I have valuable pharmacological properties, and in addition to having an inhibitory effect on inflammation and bone degradation, they have in particular antithrombotic, antiaggregatory and tumour-or metastasis-inhibiting effects.

By way of example, the compounds of general formula I were investigated for their biological effects as follows:

2i97789 1. Inhibition of binding of 3H-BIBU 52 to human thrombocytes:
A suspension of human thrombocytes in plasma is incubated with 3H-BIBU 52 [= (3S,5S)-5-[(4'-amidino-4-biphenylyl)oxymethyl]-3-[(carboxyl)methyl]-2-pyrrolidinone[3-3H-4-biphenylyl]], which replaces the 125I fibrinogen ligand known from the literature (see DE-A-4214245) and various concentrations of the substance to be tested. The free and bound ligand is separated by centrifuging and quantitatively determined by scintillation counting. The inhibition of 3H-BIBU 52 binding by the test substance is dete.rnlined from the measurements obtained.

In order to do this, donor blood is taken from an anticubital vein and anticoagulated with trisodium citrate (final concentration 13 mM). The blood is centrifuged for 10 minutes at 170 x g and the supernatant platelet-rich plasma (PRP) is removed. The remaining blood is sharply centrifuged once more in order to obtain plasma. The PRP is diluted 1:10 with autologous plasma. 750 l are incubated with 50 l of physiological saline solution, 106 l of test substance solution, 50 l of 14C-sucrose (3,700 Bq) and 50 l of 3H-BIBU
52 (final concentration: 5 nM) at ambient temperature for 20 minutes. In order to measure the non-specific binding, 5 l c._ of BIBU 52 (final concentration: 30 M) are used instead of the test substance. The samples are centrifuged for 20 seconds at 10,000 x g and the supernatant is poured off.
100 l thereof are measured in order to determine the free ligand. The pellet is dissolved in 500 l of 0.2N NaOH, 450 l are mixed 2 ml of scintillator and with 25 l of 5N HC1 and measured. The residual plasma remaining in the pellet is determined from the 14C-content and the bound ligand is determined from the 3H-measurement. After the non-specific binding has been deducted, the pellet activity is plotted against the concentration of the test substance and the concentration for a 50o inhibition of binding is determined.

2. Antithrombotir activity Method Thrombocyte aggregation is measured using the Born and Cross method (J. Physiol. 170: 397 (1964)) in platelet-rich plasma taken from healthy volunteers. To inhibit coagulation the blood is mixed with 3.1411 sodium citrate in a volume ratio of 1:10.

Collagen-induced aggregation The pattern of the decrease in optical density of the platelet suspension is photometrically measured and recorded after the addition of the aggregation-triggering substance. The rate of aggregation is determined from the angle of inclination of the density curve. The point on the curve where there is maximum light transmittance is used to calculate the optical density.
The amount of collagen used is a5 small as possible but sufficient to produce an irreversible reaction curve.
Standard commercial collagen produced by Hormonchemie of Munich is used.
.
Before the addition of the collagen, the plasma is incubated for 10 minutes with the substance at 37 C.

From the measurements obtained an EC50 is determined graphically, indicating a 50a change in the optical density in terms of the inhibition of aggregation.

They are also suitable for parallel therapy in thrombolysis with fibrinolytics or vascular interventions such as transluminal angioplasty or in the treatment of shock, psoriasis, diabetes and inflammation.
