Description: NOVEL MALONIC ACID DERIVATIVES, PROCESSES FOR THEIR PREPARATION, THEIR USE AND PHARMACEUTICAL COMPOSITIONS CONTAINING THEM ( INHIBITIO OF FACTOR XA ACTIVITY) The present invention relates to new compounds for the inhibition of blood clotting proteins, and more particularly, to malonic acid derivatives of the formula I, in which R(1 ), R(2), R(3), R(4), R(5), and R(6) are defined as indicated below. The compounds of formula I are inhibitors of the biood clotting enzyme factor Xa. The invention also relates to processes for the preparation of the compounds of formula I, to methods of inhibiting factor Xa activity and of inhibiting blood clotting, to the use of the compounds of formula I in the treatment and prophylaxis of diseases which can be treated or prevented by the inhibition of factor Xa activity such as thromboembolic diseases, to and the use of the compounds of formula I in the preparation of medicaments to be applied in such diseases. The invention further relates to compositions containing a compound of formula I in admixture or otherwise in association with an inert carrier, in particular pharmaceutical compositions containing a compound of formula I together with pharmaceutically acceptable carrier substances and auxiliary substances. The ability to form blood clots is vital to survival. In certain disease states, however, the formation of blood clots within the circulatory system is itself a source of morbidity. It is nevertheless not desirable in such disease states to completely inhibit the clotting system because life threatening hemorrhage would ensue. In order to reduce the instances of the intravascular formation of blood clots those skilled in the art have endeavoured to develop an effective inhibitor of factor Xa, or prothrombinase, the enzyme which is incorporated into the prothrombinase complex where it serves to activate thrombin during clot formation. Appropriate concen- trations of such an inhibitor would increase the level of prothrombinase forming agents required to initiate clotting, but would not unduly prolong the clotting process once a threshold concentration of thrombin had been obtained. Blood coagulation is a complex process involving a progressively amplified series of enzyme activation reactions in which plasma zymogens are sequentially activated by limited proteolysis. Mechanistically the blood coagulation cascade has been divided into intrinsic and extrinsic pathways, which converge at the activation of factor X; subsequent generation of the thrombin proceeds through a single common pathway (see Scheme 1 ). Intrinsic Extrinsic telet Aggregation Prothrombin Thrombin Fibrinogen Fibrin Scheme 1 : Blood coagulation cascade Present evidence suggests that the intrinsic pathway plays an important role in the maintenance and growth of fibrin formation, while the extrinsic pathway is critical in the initiation phase of blood coagulation. It is generally accepted that blood coagulation is physically initiated upon formation of a tissue factor (TF)/factor Vila complex. Once formed, this complex rapidly initiates coagulation by activating factors IX and X. The newly generated activated factor X, i. e. factor Xa, then forms a one-to-one complex with factor Va and phospholipids to form a prothrombinase complex, which is responsible for converting soluble fibrinogen to insoluble fibrin via the activation of thrombin from its precursor prothrombin. As time progresses, the activity of the factor Vila/tissue factor complex (extrinsic pathway) is suppressed by a Kunitz-type protease inhibitor protein, TFPI, which, when complexed to factor Xa, can directly inhibit the proteolytic activity of factor Vila/tissue factor. In order to maintain the coagulation process in the presence of an inhibited extrinsic system, additional factor Xa is produced via the thrombin-mediated activity of the intrinsic pathway. Thus, thrombin plays a dual autocatalytic role, mediating its own production and the conversion of fibrinogen to fibrin. The autocatalytic nature of thrombin generation is an important safeguard against uncontrolled bleeding and it ensures that, once a given threshold level of prothrombinase is present, blood coagulation will proceed to completion, effecting, for example, an end of the hemorrhage. Thus, it is most desirable to develop agents that inhibit coagulation without directly inhibiting thrombin. However, despite the long standing recognition of the desirability of such an inhibitor, there is at present no effective specific Xa inhibitor in clinical use. In many clinical applications there is a great need for the prevention of intravascular blood clots or for anti-coagulant therapy. The currently available drugs are not satisfactory in many specific clinical applications. For example, nearly 50 % of patients who have undergone a total hip replacement develop deep vein thrombosis (DVT). The currently approved therapies are fixed dose low molecular weight heparin (LMWH) and variable dose heparin. Even with these drug regimes 10 % to 20 % of patients develop DVT and 5 % to 10 % develop bleeding complications. Another clinical situation for which better anticoagulants are needed concerns subjects undergoing transluminal coronary angioplasty and subjects at risk for myocardial infarction or angina. The most widely used blood-clotting inhibitors are heparin and the related sulfated polysaccharides, LMWH and heparin sulfate. These molecules exert their anti-clotting effects by promoting the binding of a natural regulator of the clotting process, anti-thrombin III, to thrombin and to factor Xa. The inhibitory activity of heparin primarily is directed toward thrombin, which is inactivated approximately 100 times faster than factor Xa. Although relative to heparin, heparin sulfate and LMWH are somewhat more potent inhibitors of Xa than of thrombin, the differences in vitro are modest (3-30 fold) and effects in vivo can be inconsequential. Hirudin and hirulog are two additional thrombin-specific anticoagulants that have been tested in clinical trials. However, these anticoagulants, which inhibit thrombin, also are associated with bleeding complications. Preclinical studies in baboons and dogs have shown that specific inhibitors of factor Xa prevent clot formation without producing the bleeding side effects observed with direct thrombin inhibitors. Several specific inhibitors of factor Xa have been reported. Both synthetic and pro- tein inhibitors of factor Xa have been identified, these include, for example, antistasin ("ATS") and tick anticoagulant peptide ("TAP"). ATS, which is isolated from the leech, Haementerin officinalis, contains 119 amino acids and has a Ki for factor Xa of 0.05 nM. TAP, which is isolated from the tick, Ornithodoros moubata, contains 60 amino acids and has a Ki for factor Xa of about 0.5 nM. The effectiveness of recombinantly-produced ATS and TAP have been investigated in a number of animal model systems. Both inhibitors decrease bleeding time compared to other anticoagulants, and prevent clotting in a thromboplastin-induced, ligated jugular vein model of deep vein thrombosis. The results achieved in this model correlate with results obtained using the current drug of choice, heparin. Subcutaneous ATS also was found to be an effective treatment in a thromboplastin-induced model of disseminated intravascular coagulation (DIC). TAP effectively prevents "high-shear" arterial thrombosis and "reduced flow" caused by the surgical placement of a polyester ("DACRON") graft at levels that produced a clinically acceptable prolongation of the activated partial thromboplastin time (aPTT), i.e. less than about two fold prolongation. By comparison, standard heparin, even at doses causing a five fold increase in the aPTT, did not prevent thrombosis and reduced flow within the graft. The aPTT is a clinical assay of coagulation which is particularly sensitive to thrombin inhibitors. ATS and TAP have not been developed clinically. One major disadvantage of these two inhibitors is that administration of the required repeated doses causes the generation of neutralizing antibodies, thus limiting their potential clinical use. Moreover, the sizes of TAP and ATS render oral administration impossible, further restricting the number of patients able to benefit from these agents. A specific inhibitor of factor Xa would have substantial practical value in the practice of medicine. In particular, a factor Xa inhibitor would be effective under circumstances where the present drugs of choice, heparin and related sulfated polysaccharides, are ineffective or only marginally effective. Thus, there exists a need for a low molecular weight, factor Xa-specific blood clotting inhibitor that is effective, but does not cause unwanted side effects. Low molecular weight, factor Xa-specific blood clotting inhibitors, that are effective but does not cause unwanted side effects have been described (International Application WO 9529189). Indole derivatives as low molecular weight, factor Xa- specific blood clotting inhibitors have been proposed in European application 97122901.8. However, besides being an effective factor Xa-specific blood clotting inhibitor, it is desirable that such inhibitors will also have advantageous pharmacological properties, for instance high stability in plasma and liver and high selectivity versus other serine proteases. Thus there exists an ongoing need for novel low molecular weight, factor Xa-specific blood clotting inhibitors that are effective and which will have the above advantages as well. The present invention satisfies this need by providing novel factor Xa activity inhibiting malonic acid derivatives of formula I and by providing related advantages as well. EP-A 0 075 896 discloses malonic acid derivatives which are used as intermediates for the synthesis of compounds which have an enkephalinase inhibitory activity. The present invention provides new malonic acid derivatives of formula I which inhibit factor Xa activity but do not substantially inhibit the activity of other proteases especially those involved in the blood coagulation pathway.

Suitable acids are, in particular, pharmaceutically utilizable or non-toxic salts. Examples of such acids are those given below as examples of acids which can form physiologically acceptable salts with the compounds of formula I containing basic groups. If a compound of formula I contains an anion X " and simultaneously is present as an acid addition salt formed at a basic group, the anion X ' can be the same or different as the anion introduced by salt formation. The present invention also covers inner salts (or betaines) of the compounds of formula I. Physiologically acceptable salts of the compounds of formula I are, in particular, pharmaceutically utilizable or non-toxic salts. Such salts are formed, for example, from compounds of formula I which contain acid groups, for example carboxylic acid groups. Examples of such salts are, for example, salts containing cations of alkali metals or alkaline earth metals, such as, for example, sodium, potassium, magnesium or calcium, or the unsubstituted ammonium cation or organic ammonium cations, the latter including cations obtained from physiologically acceptable organic amines, such as, for example, methylamine, ethylamine, triethylamine, etha- nolamine, tris(2-hydroxyethyl)amine or amino acids by protonation, or suitable quaternary ammonium cations like, for example, tetramethylammonium.

Examples of such acids the anions of which can be present in physiologically acceptable salts of the compounds of formula I are hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, acetic acid, benzoic acid, oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid, malic acid, tartahc acid, citric acid, methanesulfonic acid, p-toluenesulfonic acid or naphthalenesulfonic acids. Physiologically acceptable salts of the compounds of formula I can be prepared according to standard procedures, for example by combining the compound of formula I with the desired base, for example an alkaline metal hydroxide or carbonate or hydrogen carbonate or an amine, or with the desired acid in a solvent or diluent. A physiologically acceptable salt of a compound of formula I can also be prepared from another salt, for example trifluoroacetic acid salt by cation exchange or anion exchange by standard procedures.

The present invention relates both to pure enantiomers and mixtures of enantiomers in all ratios and to pure diastereomers and mixtures of diastereomers in all ratios. The invention covers mixtures of two stereoisomers as well as mixtures of more than two stereoisomers of formula I, and all ratios of stereoisomers in the mixtures. The compounds of formula I can also be present as E isomers or Z isomers. The present invention relates to both pure E and Z isomers and to mixtures of E/Z isomers in all ratios. Diastereomers, including E/Z isomers, can be separated into the individual isomers, for example, by chromatography. Racemates can be separated into the two enantiomers by chromatography on chiral phases or by resolution according to standard procedures. Pure enantiomers can otherwise also be obtained by employing into the synthesis optically active starting materials.

O-Methylisourea (S. Weiss and H. Krommer, Chemiker-Zeitung 98 (1974), 617-618) 2. S-Methylisothiourea (R. F. Borne, M. L. Forrester and I. W. Waters, J. Med. Chem. 20 (1977), 771-776) 3. Nitro-S-methylisothiourea (L. S. Hafner and R. E. Evans, J. Org. Chem. 24 (1959) 1157) 4. Formamidinosulfonic acid (K. Kim, Y.-T. Lin and H. S. Mosher, Tetra. Lett. 29 (1988), 3183-3186) 5. 3,5-Dimethyl-1-pyrazolylformamidinium nitrate (F. L. Scott, D. G. O'Donovan and J. Reilly, J. Amer. Chem. Soc. 75 (1953), 4053-4054) 6. N,N'-Di-tert-butyloxycarbonyl-S-methylisothiourea (R. J. Bergeron and J. S. McManis, J. Org. Chem. 52 (1987), 1700-1703) N-Alkoxycarbonyl-, N,N'-dialkoxycarbonyl-, N-alkylcarbonyl- and N,N'-dialkylcarbonyl-S-methylisothiourea (H. Woliweber, H. Kόlling, E. Niemers, A. Widdig, P. Andrews, H.-P. Schulz and H. Thomas, Arzneim. Forsch./Drug Res. 34 (1984), 531-542). Amidines can be prepared from the corresponding cyano compounds by addition of alcohols, for example methanol or ethanol, in acidic anhydrous medium, for example dioxane, methanol or ethanol, and subsequent aminolysis, for example treatment with ammonia in alcohols such as, for example, isopropanol, methanol or ethanol (G. Wagner, P. Richter and Ch. Garbe, Pharmazie 29 (1974), 12-55). Further methods of preparing amidines are the addition of hydrogen sulfide to the cyano group, followed by alkylation, for example methylation, of the resulting thioamide and subsequent reaction with ammonia (GDR Patent No. 235 866), and the addition of hydroxylamine which may be obtained from a hydroxylammonium salt with a base, to the cyano group followed by conversion of the amidoxime to the amidine, for example by catalytic hydrogenation. Saponification of the ester of compounds of the formula XVIII to give compounds of the formula XIX can be carried out by standard methods. Coupling of XIX with XX to give compounds of the formula I can be carried out with coupling reagents as described above. Compounds of the formula XX are comercially available or can be prepared by standard procedures which are known to one skilled in the art. Another way is the saponification by standard methods of the ester of compounds of the formula XVII to give compounds of the formula XXXII. Coupling of XXXII with XX to give compounds of the formula XXXIII and conversion of the residue R(3a) to R(3) can be done by procedures described above. By this standard procedures functional groups like cyano groups in the residue R(6) can be converted to an amidino group. Compounds of the formula I can also be obtained by method B as drawn in schemes 5 and 6. Scheme δ XXI XXII XXIII After protection of the carboxylfunction with an easily deavable protection group (such as for example (Cι-C )-alkyl, benzyl, or 4-methoxybenzyl) by standard methods, the residue R(3a) in compounds of the formulae IX, X, and XV can be transformed to the residue R(3) and deprotected as outlined above to give compounds of the formulae XXI, XXII, and XXIII. Scheme 6 XXI, XXII, or XXIII coupling reagent XXVI The protected amino acid XXIV, wherein PG is a suitable amino protection group, for example Fmoc, benzyloxycarbonyl (Z), or Boc, preferably Fmoc), can be coupled by standard methods as described above with compounds of the formula XX to give compounds of the formula XXV. Compounds of the formula XXV can be deprotected by standard methods, for example by standard methods for Fmoc-deprotection (L.A. Carpino et al., J. Org. Chem. 1988, 53, 6139-44) to give compounds of the formula XXVI. Compounds of the formula XXVI can be coupled with compounds of the formulae XXI, XXII, or XXIII by standard methods to give compounds of the formula I. Compounds of the formula I which contain an unsubstituted or substituted amidino, guanidino, or amino residue in the residue R(6) can be synthesized directly by coupling of compounds of the formula XIX or XXIV with compounds of the formula XX or from compounds of formula I which contain the corresponding precursor groups like cyano or amino function. The conversion of the cyano or amino function to the amidino or guanidino function can be done by standard procedures. Compounds of the formula I can also be obtained by solid phase peptide synthesis (method C) as drawn in scheme 7. Such methods are described, for example, by Steward and Young (Solid Phase Peptide Synthesis (Freeman and Co., San Francisco, 1969), which is incorporated herein by reference. Where solid phase synthesis methods are employed, the chemical composition of a compound can be manipulated while the nascent peptide is attached to the resin or after the peptide has been cleaved from the resin to obtain, for example, an N- terminal derivative. Similar modifications can also be made to a carboxy group of a compound, including a C-terminus carboxy group, which, for example, can be amidated. One skilled in the art can also synthesize a compound of the invention using solution phase organic chemistry. Scheme 7 XXXI bound to an acid deavable resin Using this method (C) (scheme 7) compounds of the formula XXVII, where an amino acid is coupled to a suitable carrier, which are for instance Wang , Trityl or Rink resin or other acid deavable resins which are known to a person skilled in the art, and wherein R(31) is R(17), R(21), or (CH 2 ) 3 -NR(33)-C(=N-R(32))-NH-R(33); wherein R(17) and R(21 ) are as defined above; R(32) is R(33), cyano, hydroxy, (d-C 6 )-alkoxy, (C 6 -Ci 4 )-aryl-(d-C 6 )-alkoxy which can also be substituted in the aryl moiety, or amino, and where residues R(32), if present more than one time in the molecule, are independent of each other and can be identical or different; R(33) is hydrogen, (d-C 6 )-alkyl, or (d-C 6 )-alkylcarbonyl; can be coupled with an Fmoc-protected amino acid XXIV using standard techniques. The resulting dipeptide XXVIII can be deprotected using base, for example a solution of 20-50 % of piperidin in dimethylformamide to obtain compounds of the formula XXIX with a primary or secondary amino group, which can be coupled to the building blocks IX, X, XV, XXI, XXII, or XXIII prepared using methods A and B to yield compounds of the formula XXX, where R(3c) has the meaning of R(3) or R(3a). Conversion of the residue R(3a) of the resulting compound XXX, where R(3c) has the meaning of R(3a), to the residue R(3) can be done as described above. Compounds of the formula I can be obtained by cleaving compounds of the formula XXXI under acidic conditions for example trifluoroacetic acid/water in different concentrations depending on the used resin varying from 1 % to 95 % of trifluoroacetic acid. These synthesized compounds can be purified using well known methods such as reverse phase-high performance liquid chromatography (RP-HPLC) or other methods of separation based, for example, on the size, charge or hydrophobicity of the compound. Similarly, well known methods such as amino acid sequence analysis or mass spectrometry (MS or HPLC/ESMS) can be used for characterizing the structure of a compound of the invention (see Example 9).

As is demonstrated in the pharmacological tests described below, the compounds of formula I inhibit factor Xa activity. They can therefore advantageously be used as pharmaceuticals, especially when it is desired to reduce factor Xa activity or to produce effects that can be achieved by inhibiting factor Xa activity in a system, such as influencing coagulation or inhibiting blood clotting. Thus, the present invention also relates to the compounds of formula I for use as pharmaceuticals as well as for the production of medicaments, especially of medicaments for treatment or prophylaxis of the conditions and diseases mentioned below and above. Further, the present invention provides a method of specifically inhibiting factor Xa activity by contacting factor Xa with a compound of formula I. More specifically, an effective amount of a compound of the invention inhibits factor Xa catalytic activity either directly, within the prothrombinase complex or as a soluble subunit, or indirectly, by inhibiting the assembly of factor Xa into the prothrombinase complex. A preferred embodiment of the invention comprises such compounds of the formula I which can inhibit factor Xa activity with a Ki < 100 μM and, preferably, with a Kj < 1 μM. As used herein, the term "factor Xa activity" refers to the ability of factor Xa, by itself or in the assembly of subunits known as the prothrombinase complex, to catalyze the conversion of prothrombin to thrombin. When used in reference to factor Xa activity, the term "inhibition" includes both the direct and indirect inhibition of factor Xa activity. Direct inhibition of factor Xa activity can be accomplished, for example, by the binding of a compound of formula I to factor Xa or to prothrombinase so as to prevent the binding of prothrombin to the prothrombinase complex active site. Indirect inhibition of factor Xa activity can be accomplished, for example, by the binding of a compound of the invention to soluble factor Xa so as to prevent its assembly into the prothrombinase complex. As used herein, the term "specific" when used in reference to the inhibition of factor Xa activity means that a compound of formula I can inhibit factor Xa activity without substantially inhibiting the activity of other specified proteases, including thrombin (using the same concentration of the inhibitor). Such proteases are involved in the blood coagulation and fibrinolysis cascade. Inhibition of factor Xa activity or the production of effects achieved by such an inhibition can take place in vivo, i. e. in an individual. As used herein, the term "individual" means a vertebrate, including a mammal such as, for example a mice, a rat, a rabbit, a dog, a pig, a monkey, and especially a human, in which factor Xa is involved in the clotting cascade. It can also take place outside the body of an individual, for example, in an extracorporeal circulation or in the treatment of blood samples from an individual, and generally in vitro. In vitro uses of the compounds of formula I are, for example, the use as a biochemical tool in scientific or analytical investigations or the use for in vitro diagnoses. A compound of formula I can advantageously be used as an anticoagulant, which can be contacted with a blood sample to prevent coagulation. For example, an effective amount of a compound of formula I can be contacted with a freshly drawn blood sample to prevent coagulation of the blood sample. As used herein, the term "effective amount" when used in this connection means an amount of a compound of formula I that inhibits factor Xa activity to the desired extent. The skilled artisan would recognize that an effective amount of a compound of the invention can be determined using the methods disclosed herein or otherwise known in the art. In view of the disclosed utility of the compounds of formula I, the skilled artisan also would recognize that an agent such as heparin can be replaced with a compound of the invention. Such a use of a compound of formula I can result, for example, in a cost saving as compared to other anticoagulants. In a further embodiment, the present invention provides a method of inhibiting factor Xa in a patient in need thereof, comprising administering to said patient an effective factor Xa inhibitory amount of a compound of formula I. As used herein, the term "patient" refers especially to a warm-blooded animal including a mammal and particularly a human. A patient is in need of treatment to inhibit factor Xa when the patient is suffering from a disease state that can be beneficially influenced by inhibiting factor Xa activity or that is expected by the clinician to be beneficially influenced by inhibiting factor Xa acitivity. The identification of those patients who are in need of treatment to inhibit factor Xa is well within the ability and knowledge of one skilled in the art. A clinician skilled in the art can readily identify, by the use of clinical tests, physical examination and medical/family history, those patients who are in need of such a treatment. Since a compound of formula I can inhibit factor Xa activity, such a compound can be used for reducing or inhibiting blood clotting in an individual. Thus, the present invention further provides a method of reducing or inhibiting the formation of blood clots in an individual, especially in a patient in need thereof, by administering a therapeutically effective amount of a compound of formula I. A therapeutically effective amount relating to the production in an individual of an effect like inhibition or reduction of blood clotting, or an effective factor Xa inhibitory amount of a compound of formula I means the amount or the dose of a compound of formula I that has to be administered to an individual in order to achieve or to maintain the desired effect or to inhibit factor Xa activity in the individual to the desired extent. Such an effective amount or dose to be administered has to be adjusted to the individual circumstances in each case. It can be readily determined by the use of conventional techniques using the methods described herein or otherwise known in the art, and by observing results obtained under analogous circumstances. In determining the effective dose, a number of factors are considered including, but not limited to: the species of patient; its size, age, and general health; the specific disease involved; the degree or the involvement or the severity of the disease; the response of the individual patient; the particular compound administered; the mode of administration; the bioavailability characteristics of the pharmaceutical preparation administered; the dose regimen selected; and the use of comcomitant medication. An appropriate dosage can be established using clinical approaches well known in the medical art. In general, in view of the above factors it is evident that the effective factor Xa inhibitory amount or the therapeutically effective amount of a compound of formula I will vary and can be varied within wide limits. Usually, an effective amount will vary from about 0.01 milligram per kilogram of body weight per day (mg/kg per day) to about 20 mg/kg per day. A daily dose of from about 0.1 mg/kg to about 10 mg/kg is preferred. These data refer to a human of about 75 kg of body weight. In particular when administering relatively large quantities, it can be favorable to subdivide the daily dose into several, for example 2, 3 or 4 subdose administrations. A compound of formula I can be administered to an individual for the treatment of a variety of clinical conditions, including, for example, the treatment and prophylaxis of cardiovascular disorders or complications associated, for example, with infection or surgery. Examples of cardiovascular disorders include restenosis, for example restenosis following angioplasty, reocclusion prophylaxis, conditions after coronary bypass operations, arterial, venous and microcirculatory disease states, cardiac infarction, angina pectohs, thromboembolic diseases, thromboses, embolism, adult respiratory distress syndrome, multi-organ failure, stroke or disseminated intravascular coagulation clotting disorder. Examples of related complications associated with surgery include, for example, deep vein and proximal vein thrombosis, which can occur following surgery. Thus, a compound of the invention is useful as a medicament for reducing or inhibiting unwanted coagulation or blood clotting in an individual. The compounds of formula I, their physiologically acceptable salts and other suitable derivatives thereof can be employed as medicaments or pharmaceuticals in the above-mentioned methods on their own, in mixtures with each other or in the form of pharmaceutical compositions which comprise, as the active ingredient, an effective amount of at least one compound of formula I and/or of a physiologically acceptable salt and/or another suitable derivative thereof in admixture or otherwise in association with one or more pharmaceutically acceptable carrier substances and auxiliary substances. In effecting treatment of a patient, compounds of formula I on their own or pharmaceutical compositions comprising them can be administered in any form or mode which makes the compounds of formula I bioavailable in effective amounts, including oral and parenteral routes. For example, they can be administered orally, subcutaneously, intramuscularly, intravenously, transdermally, intranasally, rectally, and the like. Oral administration is generally preferred but depending on the specific case other modes of administration can also be favourable, for example in an acute stage of a disease intravenous administration by means of injection or infusion. One skilled in the art of preparing formulations can readily select the proper form and mode of administration depending upon the disease state to be treated, the stage of the disease, and other relevant circumstances. Pharmaceutical compositions or medicaments comprising a compound of formula I and/or a physiologically acceptable salt and/or another suitable derivative thereof can be made by combining the compounds of formula I and/or their physiologically acceptable salts and/or other suitable derivatives thereof with pharmaceutically acceptable carrier substances and auxiliary substances, the proportion and nature of which are determined by the chosen route of administration and standard pharmaceutical practice. The pharmaceutical compositions or medicaments are prepared in a manner well known in the pharmaceutical art. The pharmaceutical compositions will, in general, contain an effective amount of a compound of formula I and/or a physiologically acceptable salt and/or another suitable derivative thereof together with a suitable amount of a carrier so as to comprise the proper dosage for administration to an individual. The pharmaceutical compositions may be adapted for oral or parenteral use and may be administered to the patient in the form, for example, of tablets, capsules, suppositories, solutions, suspensions, ointments, tinctures, nasal sprays, aerosol mixtures, implants, rods, microcapsules or the like. Thus, together with the claimed compounds the present invention provides useful pharmaceutical compositions or medicaments for inhibiting factor Xa activity and blood clotting in an individual. The present invention further encompasses a process for the preparation of pharmaceutical compositions or medicaments which comprise at least one compound of formula I and/or a physiologically acceptable salt and/or another suitable derivative thereof, as well as it encompasses the use of the compounds of formula I and/or physiologically acceptable salts and/or other suitable derivatives thereof for the preparation of medicaments, especially of medicaments for the treatment or prophylaxis of the above-mentioned diseases. Pharmaceutically acceptable carrier and auxiliary substances are referred to as substances or compositions that are non-toxic to an individual or have acceptable toxicity as determined by the appropriate regulatory agency. The carrier substance or excipient may be a solid, semi-solid, or liquid material which can serve as a vehicle or medium for the active ingredient. As used herein, the term "pharmaceutically acceptable carrier" encompasses any of the standard pharmaceutical carriers such as liquid carriers, for example phosphate buffered saline, water, an emulsion such as an oil/water or water/oil emulsion, or solid or semi-solid carriers such as, for example, lactose, corn starch, fats, waxes, etc. Suitable pharmaceutical carriers and their formulations are well known in the art and are, for example, described by Martin in Remington's Pharmaceutical Sciences, 15th Ed. (Mack Publishing Co., Easton 1975) which is incorporated herein by reference also with respect to other aspects of the ingredients and the preparation of pharmaceutical compositions. Examples of auxiliary substances are fillers, disintegrants, binders, glidants, wetting agents, stabilizers, emulsifiers, preservatives, sweeteners, dyes, flavorants, aromatizing agents, thickeners, diluents, buffering substances, solubilizing agents, agents for achieving a slow-release effect, salts for altering the osmotic pressure, coating agents, antioxidants, etc. For the purpose of oral administration, the compounds of formula I may be incorporated with excipients or inert diluents or edible carriers and used in the form of, for example, tablets, film tablets, coated tablets, pills, troches, capsules, granules, solutions, suspensions, emulsions, elixirs, syrups, wafers, chewing gums and the like, or they may be enclosed in gelatin capsule. The pharmaceutical compositions for oral administration may be varied depending upon the particular form. Usually they contain at least 1 % of the active ingredient of formula I and may conveniently contain up to about 90 % of the weight of the unit. Preferably the content of the compounds of formula I and/or their physiologically acceptable salts and/or other suitable derivatives is from about 4 % to about 70 % by weight. The amount of the active ingredient present in the compositions is such that a unit dosage form suitable for administration will be obtained. The tablets, pills, capsules, troches and the like may also contain, for example, one or more of the following carrier and auxiliary substances: binders, such as microcrystalline cellulose, gum tragacanth or gelatin; excipients, such as starch or lactose, disintegrating agents such as alginic acid, Primogel, corn starch and the like; lubricants, such as magnesium stearate or Sterotex; glidants, such as colloidal silicon dioxide; and sweetening agents, such as sucrose or saccharin may be added or flavoring agents, such as peppermint, methyl salicylate or orange flavoring. When the dosage unit form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier such as polyethylene glycol or a fatty oil. Other dosage unit forms may contain other various materials which modify the physical form of the dosage unit, for example, as coatings. Thus, tablets or pills may be coated with sugar, shellac, or other enteric coating agents. A syrup may contain, in addition to the active ingredient, for example sucrose as a sweetening agent and certain preservatives, dyes and colorings and flavors. For the purpose of parenteral administration, the compounds of formula I and/or physiologically acceptable salts thereof and/or other suitable derivatives thereof may be incorporated into a solution or a suspension. The solutions or suspensions may, for example, also include one or more of the following carrier and auxiliary substances: sterile diluents such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl paraben; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylene diaminotetra- acetic acid; buffers such as acetates, citrates or phosphates; agents for the adjustment of toxicity such as sodium chloride or dextrose. The content of the compounds of formula I in the preparations for parenteral adminstration may be varied. Usually they contain at least 0.1 % by weight of the compound of formula I. Preferably the content of the compound of formula I and/or the physiologically acceptable salts thereof and/or other suitable derivatives thereof is from about 0.1 % to 50 %. The parenteral preparations can be enclosed in ampules, disposable syringes, multiple dose vials made of glass or plastic, or infusion bottles. Suitable excipients for microcapsules, implants and rods are, for example, mixed polymers of glycolic acid and lactic acid. Materials used in preparing the various pharmaceutical compositions should be pharmaceutically pure and non-toxic in the amounts used. Besides one or more compounds of formula I and/or one or more physiologically acceptable salts thereof and/or one or more other suitable derivatives thereof as active compounds the pharmaceutical compositions according to present invention may also contain one or more other pharmacologically active compounds. In another, more general embodiment the present invention provides compositions comprising at least one compound of formula I and/or salt thereof and/or another suitable derivative thereof in admixture or otherwise in association with one or more inert carriers. These compositions are useful, for example, as assay standards, as convenient means of making bulk shipments, or as pharmaceutical compositions. An assayable amount of a compound of formula I is an amount which is readily measurable by standard assay procedures and techniques as are well known and appreciated by those skilled in the art. Assayable amount of a compound of formula I will generally vary from about 0.001 % to about 90 % of the composition by weight. Inert carriers can be any material which does not degrade or otherwise covalently react with a compound of formula I. Examples of suitable inert carriers are water; aqueous buffers, such as, for example, those which are generally useful in High Performance Liquid Chromatography (HPLC) analysis; organic solvents, such as acetonitrile, ethyl acetate, hexane and the like; and pharmaceutically acceptable carrier and auxiliary substances. The compounds of formula I can also be used as starting materials or chemical intermediates in the preparation of other compounds, especially in the preparation of other pharmacologically active compounds. Examples for such conversions of compounds of the invention into other compounds of the invention are given below. For this use, besides the compounds of formula I and their physiologically acceptable salts also other salts of the compounds of the formula I can be useful which not suitable or less suitable for use as pharmaceuticals. Thus, the present invention also relates to compounds of the formula I and their salts in general as chemical intermediates, especially as intermediates in the preparation of pharmacologically active compounds. The following tests can serve to investigate the pharmacological activity and to illustrate the utility of the compounds of the present invention as factor Xa inhibitors. Test 1: In Vitro Inhibition of Selected Purified Coagulation Enzymes and Other Serine Proteases The ability of a compound of formula I to inhibit factor Xa, thrombin, plasmin, elastase and trypsin may be assessed by determining the concentration of compound of formula I that inhibits enzyme activity by 50 % (IC 5 o). Purified enzymes are used in chromogenic assays. To determine the inhibition constant, the IC S0 value is corrected for competition with substrate using the formula: Kj = IC50 x (1/{1 + ((substrate concentration)/substrate Km)}) where Km is the Michaelis-Menten-constant (Y.-C. Chen and W.H. Prusoff, Biochem. Pharmacol. 22: 3099-3018 (1973), which is incorporated herein by reference). a. Factor Xa Assay TBS-PEG buffer (50 mM Tris-Cl, pH 7.8, 200 mM NaCl, 0.05 % (w/v) PEG-8000, 0.02 % (w/v) NaN 3 ) is used for this assay. The IC 5 o is determined by combining in appropriate wells of a Costar half-area microtiter plate 25 μl human factor Xa (Enzyme Research Laboratories, Inc.; South Bend, IN) in TBS-PEG; 40 μl 10 % (v/v) DMSO in TBS-PEG (uninhibited control) or various concentrations of the compound to be tested diluted in 10 % (v/v) DMSO in TBS-PEG; and substrate S-2765 (N- benzyloxycarbonyl-D-Arg-Gly-L-Arg-p-nitroanilide; Kabi Pharmacia, Inc.; Franklin OH) in TBS-PEG. The assays are performed by pre-incubating the compound of formula I plus enzyme for 10 min, then the assay is initiated by adding substrate to obtain a final volume of 100 μl. The initial velocity of chromogenic substrate hydrolysis is measured by the change in absorbance at 405 nm using a Bio-tek Instruments kinetic plate reader (Ceres UV900HDi) at 25 °C during the linear portion of the time course (usually 1.5 min after addition of substrate). The concentration of inhibitor that causes a 50 % decrease in the rate of substrate hydrolysis is predicted by linear regression after plotting the relative rates of hydrolysis (compared to the uninhibited control) versus the log of the compound of formula I concentration. The enzyme concentration is 0.5 nM and substrate concentration is 140 μM. Thrombin Assay TBS-PEG buffer is used for this assay. The IC 5 o is determined as above for the Factor Xa assay, except that the substrate is S-2366 (L-PyroGlu-L-Pro-L-Arg-p- nitroanilide; Kabi) and the enzyme is human thrombin (Enzyme Research Laboratories, Inc.; South Bend IN). The enzyme concentration is 175 μM. c. Plasmin Assay TBS-PEG buffer is used for this assay. The ICso is determined as described above for the factor Xa assay, except that the substrate is S-2251 ((D)-Val-L-Leu-L-Lys-p- nitroanilide; Kabi) and the enzyme is human plasmin (Kabi). The enzyme concentration is 5 nM and the substrate concentration is 300 μM. d. Trypsin Assay TBS-PEG buffer containing 10 mM CaCI 2 is used for this assay. The IC 5 o is determined as described above in the factor Xa assay, except that the substrate is BAPNA (Benzoyl-L-Arg-p-nitroanilide; Sigma Chemical Co.; St. Louis MO) and the enzyme is bovine pancreatic trypsin (Type XIII, TPCK treated; Sigma). The enzyme concentration is 50 nM and the substrate concentration is 300 μM. e. Elastase Assay Tris-Cl, pH 7.4, 300 mM NaCl, 2 % (v/v) N-methyl-pyrrolidone, 0.01 % (w/v) NaN 3 buffer is used for this assay. The IC 50 is determined as described above in the factor Xa assay, except that the substrate is succinyl-Ala-Ala-Ala-p-nitroanilide (Calbiochem-Nova Biochem Corp.; San Diego CA) and the enzyme is human neutrophil elastase (Athens Research and Technology, Inc.; Athens GA). The enzyme concentration is 75 nM and the substrate concentration is 600 μM. The control compound is "TENSTOP" (N-alpha-tosyl-Gly-p-amidinophenylalanine methyl ester; American Diagnostica, Inc.; Greenwish CT), which is a reversible factor Xa inhibitor (Stuerzebecher et al., Thromb. Res. 54: 245-252 (1989); Hauptmann et al., Thromb. Haem. 63: 220-223 (1990), each of which is incorporated herein by reference). Test 2: Assays for Determining Inhibition of Coagulation The effectiveness of compounds of formula I may be assessed by the in vitro prothrombin time (PT) assay using pooled human donor plasma. An ex vivo assay may also be used in which plasma is collected at various times after intravenous (iv) administration of a compound of formula I to rats or to rabbits or intraduodenal (id) administration to rats and analysis using the PT assay to determine plasma half-life. The PT assay is initiated with a thromboplastin dilution selected to obtain an extended and highly reproducible coagulation endpoint, referred to as the "dilute PT assay" as described below. The effectiveness of various compounds may also be determined using an in vivo rat arteriovenous shunt model of thrombosis. a. In Vitro Dilute Prothrombin Time Assay 100 μl prewarmed (37 °C) pooled human platelet poor plasma (PPP) is added to a fibrometer cup (Baxter Diagnostics., Inc.; McGaw Park IL). 50 μl of various concentrations of a compound of formula I in TBS-BSA with calcium (50 mM Tris-Cl, 100 mM NaCl, 0.1 % (w/v) bovine serum albumin, 20 mM CaCI 2 ) is added. In control experiments, TBS-BSA with calcium but without test compound of formula I is added for measurement of uninhibited coagulation time. 150 μl diluted prewarmed rabbit thromboplastin (Baxter) with calcium is added to the fibrometer cup and the fibrometer timer is started. A rabbit thromboplastin dilution curve is obtained prior to treating the compound and is used to choose a thromboplastin dilution that allows approximately 30 sec PT time for uninhibited controls. The experimental concentration giving 50 % inhibition of coagulation (ECso) with test compound is calculated from the dilution curve times. Alternatively, the dilute prothrombin time assay is conducted using the "research" mode on an Instrumentation Laboratories (IL) ACL3000-plus automated coagulation instrument (IL; Milan, Italy). Thromboplastin is diluted until a clotting time of 30-35 seconds is achieved. This clotting time is taken as 100 % activity. A standard curve for calibration is established by serial 2-fold dilution of the diluted thromboplastin reagent (rabbit brain IL-brand thromboplastin). During the assay, a 50 μl sample (plasma separated by centrifugation) is mixed with 100 μl thromboplastin reagent and nephelometric readings are taken over 169 sec. Coagulation time is determined from the maximal rate of change of light scatter calculated by the instrument. Inhibition is expressed as percent activity as determined by comparison with the calibration curve. b. Ex Vivo Dilute Prothrombin Time Assay A test compound of formula I is administered iv either through the tail vein (rat) or ear vein (rabbit) following an approved protocol. 0.5 ml blood samples are removed at timed intervals after administration of a test compound of formula I from a cannulated carotid artery (rat) or auricular artery (rabbit). After centrifugation to obtain PPP, the plasma is immediately stored on ice or frozen. For dilute prothrombin time determination, the plasma is prewarmed and assayed as described above. Percent inhibition is calculated from a thromboplastin dilution curve, which is run with each series of samples, and used to determine the time at which approximately 50 % of the initial anticoagulant activity remains in the plasma The test compounds of formula I can also be administered to rats using an intraduodenal dosing protocol. Male Sprague-Dawley rats weighing approximately 300 g are anesthetized with a combination of ketamine/xylazine, subcutaneously, following an approved protocol. The right carotid artery is cannulated for blood sampling. A laparotomy is performed and duodenum is cannulated with a ball-tip needle and tied into place to ensure that the suture is distal to the point of insertion. An additional tie is placed proximal to the insertion point to prevent leakage of gastric contents. The effectiveness of the suture in preventing a compound from reaching the site of insertion is tested by pressure testing at the conclusion of each experiment. The point of insertion is approximately 4 cm from the duodenal-gastric junction. Compounds are administered in 1 ml normal saline. A 0.7 ml blood sample is drawn prior to administration of the test compound of formula I and at 15, 30, 60, 90 and 120 min after administration. Plasma is separated by centrifugation and assayed for inhibition of coagulation using the dilute prothrombin time assay. Rat Arteriovenous Shunt Model of Thrombosis The anti-thrombotic efficacy of various compounds of the invention may be assessed using rat extracorporeal arteriovenous (AV) shunt. The AV shunt circuit consisted of a 20 cm length of polyethylene (PE) 60 tubing inserted into the right carotid artery, a 6 cm length of PE 160 tubing containing a 6.5 cm length of mercerized cotton thread (5 cm exposed to blood flow), and a second length of PE 60 tubing (20 cm) completing the circuit into the left jugular vein. The entire circuit is filled with normal saline prior to insertion. Test compounds of formula I are administered by continuous infusion into the tail vein using a syringe pump and butterfly catheter (infusion volume 1.02 ml/h). A compound is administered for 30 min, then the shunt is opened and blood allowed to flow for a period of 15 min (total of 45 min infusion). At the end of the 15 min period, the shunt is clamped and the thread is carefully removed and weighed on an analytical balance. Percent inhibition of thrombus formation is calculated using the thrombus weight obtained from control rats, which are infused with saline.

Example 9 General method for synthesis of malonic acid derivatives on solid phase General solid-phase peptide synthesis was used to produce a part of the compounds of this invention. Such methods are described, for example, by Steward and Young (Solid Phase Peptide Synthesis (Freeman and Co., San Francisco, 1969), which is incoφorated herein by reference. Unless indicated otherwise, compounds were synthesized on polystyrene resin cross- linked with 1 % divinylbenzene. An acid sensitive linker (Rink Linker) was coupled to the solid support (Rink, Tetr. Lett. 28:3787 (1987); Sieber, Tetr. Lett. 28:2107 (1987), each of which is incoφorated herein by reference). All compounds were synthesized on a semi-automated peptide synthesizer built in house. Boc-and Fmoc-protected L- and D- amino acid derivatives were from various commercial sources like Advanced ChemTech (Louisville, KY 40228-9973, USA); Bachem (King of Prussia, PA 19406, USA) and PerSeptive Biosystems (Framingham, MA 01701 , USA). Synthesis of the compounds of formula I was carried out according to the classical Fmoc methodology (E. Atherton and R.C. Sheppard in „ Solid Phase Peptide Synthesis: A Practical Approach", IRL Press, Oxford, England, 1989) using DICI and HOBt as adivating reagents. All couplings were done in dimethylformamide or dimethylform- amide: dichloromethane (1:1 mixture) at room temperature for 40 min. Completion of coupling was monitored by ninhydrin test as described by Kaiser (Kaiser et al., Anal. Biochem. 34:595 (1970)), which is incoφorated herein by reference. A second (double) coupling was performed where coupling in the first instance was incomplete. After completion of peptide assembly on the resin, the final Fmoc deprotedion was performed followed by normal wash cycles and determination of the amount of Fmoc group released by deprotection at 302 nm. Then the malonic acid derivatives were similarly coupled by DICI/HOBt procedure. The finished resin was washed successively with dichloromethane, dimethylformamide and dichloromethane, then dried under vacuo and used in the next step. Solid-Phase Synthesis of Amidoxime: The general procedure was by mixing the resin (from the step above) of the nitrile containing substance with 20-40 equivalents of hydroxyiamine hydrochloride in presence of 1 : 1 : 1 (by volumes) mixture of thethylamine, pyridine and dimethylformamide. The suspension was usually sonicated for about 30 sec and shaked at room temperature for 12-24 hours. The completion of conversion of nitrile to amidoxime was monitored by either FT-IR (KBr disk) looking for the disappearance of-CN absoφtion at 2225 cm "1 or by cleavage of small sample of the resin by trifluoroacetic acid: H 2 O (95:5) or reagent K (see below) and determination of the molecular weight by HPLC/ESMS. The finished resin was washed with dimethylformamide, 10 % H 2 O in dimethylformamide, ethanol, dichloromethane and dried in vacuo before its use in the next step. Solid-Phase Synthesis of Amidine: Several methods are reported for the synthesis of amidine-containing compounds (for review see P.J. Dunn (1995) in "Comprehensive Organic Fundional Group Transformations: Amidines and N-Substituted Amidines", Vol. 5, 741-782 (edts. Alan R. Katritzky, Otto Meth-Cohen & Charles W. Rees), Pergamon, N.Y., 1995). None of these methods were compatible with the solid-phase organic synthesis. Here we developed the proper procedure of amidine synthesis via amidoxime precursor by reduction using excess triethylsilane in presence of soluble catalyst (DCRu). It was found that addition of triphenylphosphine in presence of acetic acid facilitated the redudion and enhanced the yield of amidine compounds. Thus, the current invention also relates to a process of the reduction of an amidoxime group on solid phase to an amidino group using excess triethylsilane in presence of the soluble catalyst dichlorotetrakis (triphenylphosphine) ruthenium (II) and optionally further in the presence of triphenylphosphin and acetic acid in a solvent, for example dimethylformamid. In a typical experiment the dried resin was added to the redudion cocktail composed of DCRu, triphenylphosphine, acetic acid, dimethylformamide and triethylsilane in a stoppered readion vessel (see example 11 ). The redudion usually will take 12-24 hours at room temperature. Additional amount of tπ ' ethylsilan was used in case of incomplete redudion and the time of readion was extended by 4-8 additional hours. The finished peptidomimetic resin was washed with dimethylformamide, ethanol, dichloromethane and suspended in reagent K (King et al., Int. J. Pept. Prot. Res. 36:255-266 (1990) cocktail (5 ml/g peptide resin) for 180 min at room temperature. Then the cleavage mixture was filtered in anhydrous diethyl ether and the solid precipitate was isolated by centrifugation and dried in vacuo over solid pellets of KOH and the solid material was dissolved in a mixture of 1:1 of 0.1 % trifluoroacetic acid in water and acetonitrile and lyophilized. For peptidomimetic purification, a sample of crude lyophilized compound was dissolved in a mixture of 0.1 % aqueous trifluoroacetic acid containing 10 % to 50 % acetonitrile. The compound solution usually filtered through a syringe connected to a 0.45 μm nylon "ACRODISC" 13 (Gelman Sciences; Ann Arbor Ml) filter. A proper volume of filtered peptidomimetic solution was injeded into a semi-preparative C 18 column (Vydac Protein and Peptide C18, 218TP1010; The Separation Group; Hesperia CA). The flow rate of a gradient or isocratic mixture of 0.1 % trifluoroacetic acid buffer and acetonitrile (HPLC grade) as an eluent was maintained using a Beckman "SYSTEM GOLD" HPLC. Elution of the peptidomimetic was monitored by UV detection at 230 nm (Beckman, System Gold, Programmable Solvent Module 126 and Programmable Detector Module 166 controlled by "SYSTEM GOLD" software). After identifying the peak corresponding to each diastereomer using MS, the compounds were colleded, lyophilized and biologically tested. MS was performed using a SCIEX API III+ instrument. In addition, NMR was performed using a General Electric instrument (300 MHz) or Bruker Avance DPX 300 (300 MHz). For NMR, samples typically were measured in DMSO-d 6 or CDCI 3 (Aldrich). Typical synthesis of individual compounds is summarized in scheme 7 and the following examples illustrate the experimental details. Example 10 2-(R,S)-(4-Carbamimidoyl-benzyl)-N-[(1 -(S)-carbamoyl-4-guanidino-butylcarb- amoyl)-(S)-cyclohexyl-methyl]-2-methyl-malonamic acid trifluoroacetic acid salt a) 2-(R,S)-(4-Cyano-benzyl)-2-methyl-malonic acid 2-Methyl-malonic acid diethyl ester (5.25g, 36 mmol) was mixed with α-Bromo-p- tolunitrile (7.062 g, 36 mmol) in anhydrous dimethylformamide (70 ml). In a separate vessel potassium tert-butoxide (4.4 g, 39 mmol) was dissolved in anhydrous dimethylformamide (30 ml) and added slowly via a syringe to the reaction mixture. The reaction mixture was stirred over night at room temperature. The completion of the reaction was monitored by TLC. After evaporation of dimethylformamide in vacuo, the residue was suspended in 500 ml of 10 % aqueous hydrochloric acid and extracted by dichloromethane (2x150 ml). The combined layers were washed with water and dried over magnesium sulfate. After evaporation of dichloromethane the residue was recrystallized from methanol:water to give a white solid with mp.: 84-86 °C. This crude diester (2.52 g) was hydrolyzed by lithiumhydroxide in wateπtetrahydrofuran and the product (diacid) was extracted with dichloromethane after acidifying slowly with concentrated hydrochloric acid. The organic layer was dried (magnesium sulfate), evaporated, and the residue recrystallized from ether/hexane. The product was a white solid with mp.: 140 °C and characteristic NMR. The compound was used in the next step without further purification. b) N-[(1 -(S)-Carbamoyl-4-guanidino-butylcarbamoyl)-(S)-cyclohexyl-methyl]-2-(R,S)- (4-hydroxycarbamimidoyl-benzyl)-2-methyl-malonamic acid Dried 2-(S)-amino-2-cyclohexyl-N-(1-(S)-{carbonylamino-(Rink-resin)}-4-[pmc- guanidino]-butyl)-acetamide (1 g, 0.62 mmol) was coupled to 2-(R,S)-(4-cyano- benzyl)-2-methyl-malonic acid (177 mg, 0.75 mmol) in presence of HOBt (189 mg, 1.4 mmol) and diisopropyl-carbodiimide (195 mg, 1.5 mmol) in dimethylformamide (6 ml) and coupling continued over night. The finished peptidomimetic resin was washed and subjected to hydroxylamine reaction as outlined in example 9. The resin was cleaved by trifluoroacetic acid:water (95:5) and lyophilized to give 309.5 mg of the desired product. The compound was used in the next step without further purification and checked by MS to give 560.65 (cal. 560.65). c) 2-(R,S)-(4-Carbamimidoyl-benzyl)-N-[(1-(S)-carbamoyl-4-guanidino-butylcarb- amoyl)-(S)-cyclohexyl-methyl]-2-methyl-malonamic acid trifluoroacetic acid salt The compound from step b was dissolved in saturated solution of ammonia in methanol (10 ml).
