PATENTS ACT 1990 DIVISIONAL APPLICATION NAME OF APPLICANT: Sankyo Company, Limited ADDRESS FOR SERVICE: DAVIES COLLISON CAVE Patent Attorneys 1 Nicholson Street Melbourne, 3000.
INVENTION TITLE: "Benzamidine derivatives" The following statement is a full description of this invention, including the best method of performing it known to us:
SPECIFICATION
Benzamidine derivatives This application is a divisional of Australian Patent Application No. 79574/00, the entire contents of which are incorporated herein by reference.
[Technical field] The present invention relates to benzamidine derivatives and their pharmaceutically acceptable salts having excellent inhibitory activity against factor Xa. This invention further relates to pharmaceutical compositions comprising said compounds as an active ingredient for prevention or treatment of a blood coagulation disorder. In another aspect, this invention relates to the use of said compounds in the preparation of a medicament for the prevention or treatment of a blood coagulation disorder. In another aspect, this invention relates to a method for the prevention or treatment of a blood coagulation disorder, which method comprises administering a pharmaceutically effective amount of said compounds to a warm-blooded animal in need of such treatment. In yet another aspect, this invention relates to a process for the preparation of said compounds.
[Background Art] Recently the number of patients with cardiovascular diseases is increasing in accordance with the increase in the elderly population. Among these diseases, thrombotic diseases such as cerebral infarction, myocardial infarction and peripheral occlusive diseases not only lead to death, but also cause a significant limitation in the individual and social lives of patients which have a poor prognosis. Thus, it is suggested that anticoagulant therapy against thrombotic diseases is becoming increasingly important.
Blood coagulation involves a complex cascade of enzymatic reactions that can be triggered by an initial stimulus, and amplified to terminate in the thrombin-catalyzed conversion of the soluble fibrinogen to the insoluble plasma protein fibrin. This process is known as the blood coagulation cascade and comprises the intrinsic and the extrinsic pathways.
The activated factor X (factor Xa) is a key enzyme at the point of convergence of both coagulation pathways. It forms a complex with bivalent calcium ions, phospholipids and factor Va to efficiently convert prothrornbin to thrombin, and thereby accelerates blood coagulation E.L. Smith, A.
White et al., 'Principles of Biochemistry': Mammalian Biochemistry, 7 th edition, McGraw-Hill, Inc. (1983), etc.].
Warfarin and thrombin inhibitors are currently used as anticoagulants. Although warfarin is a widely used as an orally active antithrombotic agent, it has significant clinical limitations. The anti-coagulant activity of warfarin is antagonized by vitamin K, and is often affected by interactions with the diet or commonly used drugs Clin.
Pharmacokinet., 30, 416 (1996)]. In addition, currently available thrombin inhibitors carry a hemorrhage risk as adverse events associated with their pharmacological actions, and thus novel anti-coagulants need to be developed. Since factor Xa affects thrombin formation and factor Xa inhibitors are known to exert anti-coagulant activities, factor Xa inhibitors are suggested to become a novel type of anti-coagulant Drugs, 49, 856 (1995)].
Aromatic amidine derivatives or amidinonaphthyl derivatives are described as competitive factor Xa inhibitors in Japanese Patent Application Publication No. Hei 5-208946 (EP 540051), WO 96/16940 (EP 798295) or WO 00/47553. Further, benzamidine derivatives such as N-[4-[1-acetimidoyl- 4 -piperidyloxy]phenyl]-N-[2-(3-amidinophenoxy)ethyl]sulfamoylacetic acid bis(trifluoroacetate) are described in WO 98/31661 (EP 976722).
[Disclosure of the invention] The inventors studied the pharmacological actions of various benzamidine derivatives for many years to develop compounds with excellent anti-factor Xa activity. Our study resulted in the finding that benzamidine derivatives with specific substituents exhibit excellent anti-factor Xa activity, but do not exhibit anti-trypsin activity which is associated with adverse events. Furthermore, these derivatives are useful for the prophylaxis and therapy (particularly therapy) of blood coagulation disorders. These results led to the present invention.
The present invention relates to benzamidine derivatives and their pharmaceutically acceptable salts having excellent inhibitory activity against factor Xa. This invention further relates to pharmaceutical compositions comprising said compounds as an active ingredient for the prevention or treatment of a blood coagulation disorder. In another aspect, this invention relates to the use of said compounds in the preparation of a medicament for the prevention or treatment of a blood coagulation disorder. In another aspect, this invention relates to a method for the prevention or treatment of a blood coagulation disorder, which method comprises administering a pharmaceutically effective amount of said compounds to a warm-blooded animal in need of such treatment. In yet another aspect, this invention relates to a process for the preparation of said compounds.

A compound of formula is prepared by Method
A.
109 In Step Al a compound of formula can be prepared by condensation of a compound of formula (III) with a compound of formula (IV) in the presence of a phosphine derivative and an azo compound in an inert solvent.
The inert solvent employed in Step Al is not particularly limited provided that it has no adverse effect on the reaction and dissolves the starting material to some extent. Examples of such a solvent include an aliphatic hydrocarbon such as hexane, heptane, ligroin or petroleum ether; an aromatic hydrocarbon such as benzene, toluene or xylene; a halogenohydrocarbon such as dichloromethane, chloroform, carbon tetrachloride, dichloroethane, chlorobenzene or dichlorobenzene; or an ether such as diethyl ether, diisopropyl ether, tetrahydrofuran, dioxane, dimethoxyethane or di(ethylene glycol)dimethyl ether; preferably an aliphatic hydrocarbon, an aromatic hydrocarbon, a halogenohydrocarbon or an ether, more preferably a halogenohydrocarbon (dichloromethane) or an ether (particularly diethyl ether or tetrahydrofuran).
The phosphine derivative employed in Step Al may be, for example, a tri-C1-C 6 -alkylphosphine such as trimethylphosphine, triethylphosphine, tripropylphosphine, tributylphosphine, tripentylphosphine or trihexylphosphine; a tri-C6-Cl-arylphosphine such as triphenylphosphine, triindenylphosphine or trinaphthylphosphine; or a tri-C 6
-C
1 0 -aryl phosphine which may be substituted with C1-C4 alkyl such as tolyldiphenylphosphine, tritolylphosphine, trimesitylphosphine, tributylphenylphosphine or tri-(6-ethyl- 2-naphthyl)phosphine; preferably a tri-C,-C 6 -alkylphosphine (particularly trimethylphosphine, triethylphosphine, tripropylphosphine or tributylphosphine) or a tri-C 6 -Clo-arylphosphine (particularly triphenylphosphine, triindenylphosphine or trinaphthylphosphine); and more preferably tributylphosphine or triphenylphosphine.
The azo compound employed in Step Al may be, for example, azodicarbonyldipiperidine, or a di-C 1
-C
4 -alkyl azodicarboxylate such as dimethyl azodicarboxylate, diethyl azodicarboxylate, dipropyl 110 azodicarboxylate or dibutyl azodicarboxylate; preferably azodicarbonyldipiperidine, dimethyl azodicarboxylate or diethyl azodicarboxylate.
The reaction temperature employed in Step Al varies depends on the nature of the starting materials and the reagents, but is usually between and 100°C, and is preferably between 0°C and The reaction time employed in Step Al varies depends on the nature of the starting materials, the reagents, and the reaction temperature.
It is usually from 5 minutes to 24 hours, and is preferably from 10 minutes to 6 hours.
After the completion of the reaction, the desired product of Step Al can be isolated in a conventional manner. For example, after the reaction, when insoluble materials exist in the reaction mixture, the reaction mixture is filtered and the filtrate is concentrated to give the desired product; or, after the reaction, the solvent is evaporated, the residue is partitioned between water and a solvent immiscible with water (for example, benzene, ether, ethyl acetate or the like), the extract is washed with water, dried over anhydrous magnesium sulfate or the like and concentrated to give the desired compound. The product thus obtained, if necessary, can be further purified in a conventional manner such as recrystallization, reprecipitation, chromatography or the like.
In Step A2, a compound of formula can be prepared by an appropriate combination of the following reactions: conversion of the cyano group into an amidino group, removal of the protecting group of the protected amino group, and conversion of the amino group into an acetimidoyl group; and if desired, hydrolysis of any ester group, and removal of the protecting group of any protected hydroxyl group.
The essential reaction which is the conversion of the cyano group into an amidino group, can be accomplished according to the following conventional methods: ammonolysis of an intermediate imino ether compound, which is obtained by a reaction of the starting material with an alcohol in the presence of an acid, in an inert solvent or in the absence of a solvent (preferably in an inert solvent) or hydrogenolysis of an intermediate amidoxime compound which is obtained by reaction of the starting material with a hydroxylamine compound in the presence or absence of a base in an inert solvent.
The reaction is a two-step reaction. In the first step, an imino ether derivative is obtatained by a reaction of the nitrile with an alcohol in the presence of an acid.
The inert solvent employed in the first step of reaction is not particularly limited provided that it has no adverse effect on the reaction and dissolves the starting material to some extent. Examples of such a solvent include an aliphatic hydrocarbon such as hexane, cyclohexane, heptane, ligroin or petroleum ether; an aromatic hydrocarbon such as benzene, toluene or xylene; a halogenohydrocarbon such as dichloromethane, chloroform, carbon tetrachloride, 1,2-dichloroethane, chlorobenzene or dichlorobenzene; an ether such as diethyl ether, diisopropyl ether, tetrahydrofuran, dioxane, dimethoxyethane or di(ethylene glycol)dimethyl ether; a ketone such as acetone or methyl ethyl ketone; an ester such as methyl acetate or ethyl acetate; a nitro compound such as nitromethane; an amide such as formamide, N,N-dimethylformamide, N,N-dimethylacetamide or N-methyl-2-pyrrolidinone; a sulfoxide such as dimethyl sulfoxide; or sulfolane; or mixtures thereof; preferably an aromatic hydrocarbon (particularly benzene) or a halogenohydrocarbon (particularly dichloromethane); and most preferably a halogenohydrocarbon (particularly dichloromethane).
This reaction can be conducted in an excess of alcohol, as a reagent and a solvent, and is usually conducted in an alcohol provided that there is no adverse effect on the reaction. Examples of such an alcohol include methanol, ethanol, propanol, 2-propanol, butanol, isobutanol or the like, preferably methanol or ethanol.

Anti-factor Xa activity was determined according to the method of Hara et al. (Thromb. Haemost, 71, 314 (1994), with slight modifications. A mM tris-HCI buffer (pH 8.4) containing 0.9 NaCI, 0.4 mM chromogenic substrate, S-2222 (Daiichi Pure Chemicals Co., Ltd., Tokyo, Japan), and a test compound were mixed, and the reaction was started by adding 0.25 unit/ml human factor Xa (Cosmo Bio Co., Ltd, Tokyo, Japan). Distilled water instead of the test compound was added to the buffer in the cpntrol group.
The reaction mixture in a total volume of 0.1 ml was incubated for 5 min at room temperature. The absorbance at 405 nm was measured continuously using a 96-well microplate reader (model 550, BioRad), and the increase in absorbance for 5 min was calculated as an index of factor Xa activity. The ICso values, the concentration at which the compound inhibits factor Xa activity by 50 was determined to estimate the anti-factor Xa activity of the test compound.
The results indicated that benzamidine derivatives having general formula exhibit excellent inhibitory effects against factor Xa activity. The 340 compounds with ICso values less than 10 nM are listed in Table 2, where compound A indicates N-[4-[1-acetimidoyl-4-piperidyloxy]phenyl]-N-[2-(3amidinophenoxy)ethyl]sulfamoylacetic acid dihydrochloride salt, which has already been described in WO 98/31661 (EP 976722).
