Factor Xa inhibitors with aryl-amidines and derivatives, and prodrugs thereof TECHNICAL FIELD This invention relates generally to compounds with aryl-amidines, particularly amidinoaryl- cyclopropanes, amidinoarylmethyl-pyrroles, amidinoaryl-benzenes, amidinoaryl-pyridines, amidinoaryl-alanines, and their derivatives and/or prodrugs which are inhibitors of coagulation enzyme, factor Xa (FXa), pharmaceutical compositions containing the same, and methods of using the same as anticoagulant agents for treatment and prevention of thrombosis.

BACKGROUND ART It has been generally known that various complicated enzyme reactions are related to blood coagulation processes. The final step of the reactions is a reaction converting prothrombin to thrombin, and FXa is an enzyme involved in this process. Thrombin produced by the reaction plays a role in activating platelet and converting fibrinogen to fibrin. Fibrin may be polymerized and converted to a polymer. The polymer is cross-linked with an activated blood factor xm to produce an insoluble coagulated blood. Thrombin also plays a role in activating blood factors V and VIII, which participate in the blood coagulation process.

Thus, it accelerates the blood coagulation reaction. An inhibitor of thrombin acts as an effective anticoagulant agent, inhibits activity of platelet, and avoids producing and stabilizing fibrin. Therefore, by developing novel compounds having a capability to inhibit thrombin activity, attempts have been made to prevent blood coagulation and treat many kinds of thrombosis.

In a clinical test using inhibitors of thrombin, some inhibitors inhibited effectively thrombin in blood, but did not inhibit a reaction that does newly produce thrombin. Therefore, they did not show sufficient effects. In order to control thrombin to be newly produced, excess of an inhibitor must be administrated. Therefore, many side effects such as hemorrhage were reported. However, FXa inhibitors blocked the activity of FXa, which was directly involved in producing thrombin. For this reason, attempts for developing the FXa inhibitors have

been made to treat and prevent thrombosis and diseases associated with the same.

It has been proved through animal tests of these FXa inhibitors that disadvantages of thrombin inhibitors, such as lack of ability to block producing thrombin and side effects, for example, hemorrhage, etc, could be solved. Such viewpoints had been supported by substantially many scientific evidences. The best important example is a fact that a protein inhibiting FXa has been found from animals sucking blood, such as a mite or a leech, etc. It has been proved through some animal model experiments that the protein has an effect as an anticoagulant agent. Alternatively, it has been known that the above approach has an effect from animal model experiments of deep-vein thrombosis and canine arterial thrombosis using proteins (DEGR-Xa) active sites of which FXa were chemically interrupted.

Human FXa is activated from a human factor X. The human factor X is a protein that a light-chain consisting of 139 amino acids is connected to a heavy-chain consisting of 303 amino acids by one disulfide bond. The light-chain includes 11 y-carboxylated glutamic acids and one p-hydroxylated aspartic acid after protein expression. The heavy-chain has about 15% of glycosylated amino acids and includes also catalytic domains.

A process for activating from factor X to FXa comprises an intrinsic or extrinsic pathway.

When all materials required for blood coagulation process are presented in blood, it is said 'intrinsic pathway.'Materials associated herewith include factor IX and factor XI of a serine protease type protein, and factor Vulc of a non-enzymatic co-factor, etc. The blood coagulation process begins activating factor XI to factor XIa. Factor XIa allows for factor IX to be converted to factor IXa, and the resulting factor IXa binds to factor VIM on a phospholipid surface to produce a tenase complex. This tenase plays a role in converting factor X to FXa. When a tissue factor is introduced outside in blood, it is said"extrinsic pathway."The tissue factor binds to factor VII and activates the bound factor complex.

The resulting factor VIIa-tissue factor complex plays a role in directly converting factor X to FXa. Such resulting FXa binds to co-factor Va on phospholipid surface to comprise a prothrombinase complex. This complex allows for prothrombin to be activated to thrombin.

One molecule of FXa produces theoretically 138 molecules of thrombin. However, prothrombin concentration in blood is about 10 times or more as high as that of FXa. Thus, high concentration of drug is required for inhibiting thrombin. FXa inhibitors maintain the

thrombin concentration in blood at a physiologically required level for thrombogenesis, but thrombin inhibitors do not. Therefore, as mentioned above, FXa inhibitors reduce side effects such as hemorrhage and thus have an important advantage in terms of safety.

For the above reasons, there is a need for FXa inhibitors as well as thrombin inhibitors.

Worldwide research institutions have actively conducted efforts to develop FXa inhibitors.

Bis amidine-based compounds which have been developed as an effective FXa inhibitor are represented by DX9065a (EP 0540051-A1) of Daiichi Pharmaceutical Co., Ltd., YM-60828 (J. Med. Chem. 1999, 42, 2752-2759) of Yamanouchi Company, ZK-80719 (WO 97/29067) and ZK-807369 (WO 97/21437) of Berlex Laboratories, Inc. As mentioned above, it has been known that these compounds have commonly one carboxylic acid as a bis amidine- based compound and are capable of being absorbed orally. Mono amidine-based compounds include SK-549 (J. Med. Chem. 1999, 42, 2760-2773) of Duponte-Merck Company and RPR-130737 (WO 96/40679) of Rhone-Poulenc Rorer Pharmaceuticals Inc., etc. These compounds have an excellent selectivity against thrombin, trypsin and the like enzymes, and have an excellent effect as a Fxa inhibitor. However, it has not been known whether or not the compounds may be absorbed.

The compound (18B) or (20B) is incorporated with some of a conjugated isomer. The conjugated isomer participates in a subsequent pyrrole formation reaction. It is found that the compound (18B) or (20B) is converted to a conjugated isomer in the pyrrole formation reaction to produce a pyrrole. Identically, an allylic chloride (32) is obtained by reaction of an aldehyde (30) and a vinyl Grignard reagent to produce an allylic alcohol (31), and by a rearrangement of the allylic alcohol. The allylic chloride (32) is subjected to alkoxycarbonylation to synthesize an olefin compound (23). The olefin compound is also incorporated with some conjugated isomer.

A carboxylic acid (49) is prepared by coupling compound (50) with compound (13) or compound (51) with compound (15) to obtain an ester (49A), and hydrolyzing the ester.

A process for amidinating nitrile uses the following three methods : first, a) thioamide formation with H2S, Et3N/pyndine, b) thioimidate formation with CUT c) reaction with ammonium carbonate or ammonium acetate in hot alcoholic solvent ; second, classical pinner type reaction, i. e., a) reaction of nitrile with ethanol in the presence of HCI to form ethyl imidate hydrochloride, and b) reaction with ammonium carbonate or ammonium acetate in hot alcoholic solvent ; third, a) reaction of nitrile with hydroxylamine to form the amidoxime, and b) catalytic reduction of the aldoxime to amidine.

Amidine synthesized by the above three methods is mostly isolated and purified by reverse phase liquid chromatography (acetonitrile-water, with 0. 1% trifluoroacetic acid), and then is lyophilized to obtain trifluoro acetic acid salt ; in a form of white powder. In some cases, bis or tris trifluoroacetic acid salt ; is obtained depending on the number of basic sites in the inhibitor molecules.

A process for synthesizing a prodrug is as follows : An alkoxy carbonyl amidine is obtained from the resultant amidine by using alkoxycarbonyl chloride and trialkylamine base, or it is obtained by reacting directly nitrile and 0-alkyl hydroxyamine or hydroxylamine to produce 0-alkyl amidoxime or amidoxime and reacting the resultant amidoxime with alkoxycarbonyl chloride. In many cases, prodrug is also isolated and purified by HPLC, and lyophilized to obtain as a white solid.

The reaction schemes explained above are specifically described in examples below. However, the synthesis method, number of derivatization, prodrug form, salt ; form and the like are not restricted to only detailed description explained herein.

The representative compounds of the above formula according to the present invention include compounds below. The compounds are described in order of Al, A2, A3 and A4 scaffolds.

Experiment 1. Biological activity analysis of FXa inhibitor preparations The inhibition effect of the compound of formula 1 according to the present invention is measured by a value of dissociation coefficient Ki. The value is decided by using the equation below in accordance with a method described in a reference (see, Methods in Enzymology V 80 p341-361 ; Biochemistry 27 p2144-2151, 1988).

Ki= = [E] [I1/ [E1] [E] : concentration of enzyme not binding with inhibitor [0 : concentration of inhibitior not binding with enzyme [EI] : concentration of complex of enzyme and inhibitor The dissociation coefficient Ki shows degree of which enzyme and FXa inhibitor compound are dissociated. Thus, it is meant that the more the value of dissociation coefficient is low, the more the binding ability of inhibitor to enzyme is high. Thus, this high binding ability may be estimated to show the high inhibition activity. This dissociation coefficient may be obtained by reacting FXa with a substrate, which is hydrolyzed by action of FXa, to show a chromophoric activity, and measuring a degree of chromophoric activity as a function of time in accordance with spectrometry.

A chromophoric meterial used in the present invention is Chromozyme X (Nle-Gly-Arg-4- NA). Chromozyme X is hydrolyzed by FXa to produce yellow para-nitroaniline (p-NA).

FXa inhibition activity of the compound according to the present invention may be obtained by measuring the amount of the resulting para-nitroaniline in variation of absorbency in accordance with time. That is, activity of enzyme may be measured from variation of absorbency, and the variation may be directly involved in ability of which FXa inhibits enzyme activity.

The FXa inhibiting selectivity of the compound according to the present invention to thrombin is measured as follows. The inhibition effect of the compound of formula 1 to thrombin is measured in Ki value by practicing the same method as the above measuring method of FXa inhibiting activity, and the rate ofthrombin/FXa is obtained. At this time, the experimental method of thrombin is the same as that of FXa, except that Chromozyme TH (Tosyl-Gly-Pro-Arg-4-nitroanilide acetate) is used as the substrate.

The FXa inhibition selectivity of the compound according to the present invention to trypsin is measured as follows. The inhibition effect of the compound of formula 1 to trypsin is measured in Ki value by practicing the same method as the above measuring method of FXa inhibiting activity, and the rate of trypsin/FXa is obtained. At this time, the experimental

method of thrombin is the same as that of FXa, except that N-benzoyl-Val-Gly-Arg-p- nitroanilide hydrochloride is used as the substrate.

1. Preparation of FXa a) Materials and methods Citrated plasma was purchased from Local Red Cross Blood Center (Taejon, Korea).

All reagents for isolation-purification were used in reagent grade. b) Isolation-purification of FXa Isolation-purification of FXa : The usually known method was used for isolating- purifying Factor X (S. Paul Bajaj and Jens J. Birktoft : Methods in Enzymology, Vol 222, 100-107). This method was applied to isolate and purify factor IX. Some modified method was used for isolating-purifying factor X. Solution of the resulting Factor X in Russel's viper venom (1/40 w/w)-20mM Tris-Cl (pH = 7. 5)-150mM NaCI-l OmM CaCl2 was gently shook at 37°C for 30 minutes to activate FXa, The reaction was completed by 1M EGTA to be 12. 5mM of the final concentration. The activated FXa was isolated and purified by p-aminobenzamidine-Sepharose chromatography. The isolated and purified FXa was kept in 80% ammonium sulfate-0. 1% BSA suspension status at-70 °C.

2. FXa inhibition assay a) Material Chromozyme X (Nle-Gly-Arg4-NA) of chromogenic substrate for FXa assay was purchased from Boehringer Mannheim Company. The substrate was made in 10mM DDW solution. At the time of using the solution, it was diluted with 150mM NaCI- 100 mM Tris-Cl (pH = 7. 8)- 0. 1% PEG 8000 solution to be 0. 25mM b) Inhibiting activity of FXa inhibitor

Inhibition ability of the present compound against Fxa activity was measured as follows : In each well of 96-well plate, 0. 1M tris buffer solution (pH 7. 8) comprising 150mM NaCl, and 0. 1% PEG 8000 was placed by 90 uL. Chromozyme X was dissolved in dimethylsulfoxide (DMSO) to be 0. 25mM, and then diluted with the above buffer solution to be 0. 1rnM to prepare the substrate solution. 70uL of 0. 25mM substrate solution as prepared above was added to each well. A compound according to the present invention was dissolved in DMSO to be 10mM, and then diluted with the above buffer solution to be O. 1mM, O. 01mM and 0. 001mM, respectively, to prepare an inhibitor solution. The inhibitor solution was taken in an amount from 0 to 20uL, and supplemented with tris buffer solution up to 20uL total volume of the solution to add to each well.

20uL of FXa, which was dissolved in the above tris buffer solution to be 80nM, was added to the well having the reaction solution at room temperature to begin enzyme hydrolysis. The amount of para-nitroanilide produced for 2 minutes after adding enzyme was monitored about variation of absorbency at 381nm to depict continuous spectrum of reaction time to absorbency. The above experiment was repeated for various concentration of inhibitor to obtain consecutive spectrum The initial velocity Vi was calculated from gradient within 10 minutes of the reaction time in each spectrum. Graph was depicted for a reciprocal of the initial velocity to inhibitor concentration (1/Vl). A linear equation corresponding to points on the graph was obtained. Thereafter, Ki may be calculated by using enzyme reaction equation from x intercept. Km value used in this calculation was obtained by varying concentration of the substrate to 0. 4uM at a definite enzyme concentration.

3. Effect for blood coagulation The effect for blood coagulation in accordance with the present invention was measured by the following experimental method :. a) Measurment of aPTT

Blood was gathered from an animal or human, and then diluted with 3. 8% sodium citrate solution to isolate blood plasma. 5uL of the solution of a compound (5uM) according to the present invention and 50uL of Platelin LS (Organon Teknika) were added to 45uL of blood plasma, and then reacted at 37°Cfor 5 minutes. 50uL of 25mM CaCl2 was added to the blood plasma to measure a clotting time of blood plasma.

The clotting time of blood plasma is a time wherein absorbency at 340nm is 0. 1. b) Measurement of PT 5uL of the solution according to the present invention was added to 45uL of blood plasma, and then reacted at 37 Cfor 3 minutes. 100uL of Simplastin (Organon Teknika) was added to the blood plasma to measure a clotting time of blood plasma.

The clotting time of blood plasma is a time wherein absorbency at 340nm is 0. 1. c) Animal model Inhibition ability against thrombus formation was measured in animal model. Male white rats (Sprague Dawley) were grown at 20-22 °C and under light and darkness at 12 hour intervals by using the commercially available standard feed in a laboratory animal room of LG Chemical Co., Ltd. The rats weighing 250-300 g were used in 3-4 of rats per one experimental group.

Firstly, rats were anesthetized by intraperitoneal injection of urethane in 1. 3 g per kg of body weight. With consecutive injection of the compounds in examples via left femoral vein, abdomen of rats were incised to open inferior vena cava, and blood vessels were isolated from ambient tissue on sites under left renal vein. After the blood vessels were loosely wound with para film (25 x 8mm), intestines were returned to abdominal cavity and abdominal cavity incision was sealed temporarily by a hemostatic forceps.

Inferior vena cava was opened again 15 minutes after the compounds in examples were consecutively injected, followed by winding para film, and a filter paper (diameter 6mm) wetted with 35% FeCl3 solution was quietly placed on the blood vessels wound with para film. Thereafter, the blood vessels and filter paper were again wound with para film. With consecutive injection of the compounds in examples, 15 minutes after the filter paper was applied, it was separated. The compounds in examples were injected

for further 45 minutes. Thereafter, inferior vena cava was extracted to take the produced thrombus and measure their weight.

4. Absorption effect on oral administration The absorption effect of the compound according to the present invention was decided by measuring drug concentration in blood in accordance with the following experiment method. Male rats and dogs were fasted for 18 hours, respectively, and then the experiment was performed. 1% (10 mg/mL) solution of a compound in an example was prepared by using an appropriate solution aid, and then orally administrated. After taking blood at a definite interval, the blood was extracted with methylenechloride in liquid phase, and again reverse extracted to measure drug concentration in blood by high performance liquid chromatography (HPLC).

5. Selectivity against thrombin and trypsin a) Selectivity against thrombin Inhibiting ability of a compound according to the present invention against thrombin activity was measured as follows.

In 1. 5mL cuvette, 0. 1M tris buffer solution (pH 7. 8) comprising 150mM NaCI, and 0. 1% PEG 8000 (molecular weight 8000) was placed by 1160uL Chromozyme X was dissolved in dimethylsulfoxide (DMSO) to be 0. 1 mM, and diluted with the above buffer solution to be 0. 1mM to prepare the substrate solution. 225uL of 0. 1 mM substrate solution as prepared above was added to cuvette. The compound of the present invention was dissolved in DMSO to be 10mM, and diluted with the above buffer solution to be O. ImM, O. OImM and 0. OOImM, respectively, to prepare an inhibitor solution. The inhibitor solution was taken in an amount from 0 to 20uL, and supplemented with tris buffer solution up to 20uL of total volume of the solution to add to the cuvette.

15uL of human thrombin, which was dissolved in the above tris buffer solution to be 0. lmg/mL, was added to the cuvette having the reaction solution at room temperature to

begin enzyme hydrolysis. The amount of para-nitroanilide produced for 2 minutes after adding enzyme was monitored about variation of absorbency at 381nm to depict continuous spectrum of reaction time to absorbency. The above experiment was repeated for various concentrations of inhibitor to obtain consecutive spectrum The initial velocity Vi was calculated from gradient within 30 sec of the reaction time in each spectrum. A graph was depicted for a reciprocal of the initial velocity to inhibitor concentration (lare). A linear equation corresponding to points on the graph was obtained. Thereafter, Ki may be calculated by using enzyme reaction equation from x intercept. Km value used in this calculation was obtained by varying concentration of the substrate to 5. 2uM at a definite enzyme concentration.

Ks of velocity coefficient was obtained by the following experiment method, using the same solution and concentration as those used for obtaining Ki coefficient.

That is, 1160 uL of the buffer solution was placed in 1. 5mL cuvette, and then 15uL of 0. lmg/mL human thrombin solution and 100uL of the inhibitor solution were placed herein to keep at room temperature for 15 minutes. Thereafter, with adding 225uL of the substrate solution to the above solution., variation of absorbency was monitored in accordance with variation of time for 2 minutes. Gradient was measured about parts showing straight line from the resulting consecutive spectrum to represent Vs. This experiment was repeated for various concentrations of inhibitor to obtain Vs values and depict a graph of 1/Vs against inhibitor concentration. A linear equation corresponding to points on the graph was obtained. Thereafter, Ks was calculated by using enzyme reaction equation from x intercept b) Selectivity against trypsin Inhibition activity of a compound according to the present invention was measured by performing the experiment as explained above concerning FXa.

20uM solution of N-benzoyl-Val-Gly-Arg-p-nitroanilide hydrochloride was used as a substrate. An inhibitor solution with various concentrations in the range of 0 to 120uM was used. Trypsin was dissolved in 0. 1N HCI, and supplemented with the above tris

buffer solution to be 45ug/mL. Thereafter, 40uL of the trypsin solution was used. The remaining procedure and the used amounts of materials (for example, 0. 2 mL of total volume of the reaction solution) and the like were the same as those of the experiment for thrombin. Also, Km was decided in the same method as used in Ki calculation.

Value of Km was 20. 2uM.

In accordance with the method mentioned above, each enzyme activity of the compound according to the present invention against FXa, thrombin and trypsin was represented by Ki value, and the selectivity of the compound against FXa represented by thrombin/FXa and trypsin/FXa. The results are shown in table 1 below.
