BACKGROUND OF THE INVENTION

Stuerzebecher et al., Thrombosis Research, vol. 9, 637-646 (1976) describes comparative studies of a number of benzamidine derivatives as Factor Xa inhibitors. The most active inhibitors were 3-amidino-phenylaryl derivatives.

Tidwell et al., Thrombosis Research, vol. 19, 339-349 (1980) describes Factor Xa inhibitory activity of a series of heterocyclic aromatic mono- and di-amidines.

Stuerzebecher et al., Thrombosis Research, vol. 17, 545-548 (1980) describes Factor Xa inhibitory activity of a series of a,a'-bis-(4-amidinobenzyl) cycloalkanones, a,a'-bis-(4-aminobenzylidene)- and a,a'-bis-(3-aminobenzylidene) cycloalkanones with 5 to 8-membered rings, the corresponding non-cyclic derivatives, and derivatives containing only one amidino group.

Hauptmann et al., Blood Coagulation and Fibrinolysis, vol. 4, 577-582(1993) and Hauptmann et al., Thromb. Haemostasis, vol. 63(2), 220-223(1990) report testing of several synthetic compounds as Factor Xa inhibitors: Na-tosylglycyl-3-amidinophenylalanine methyl ester; 2,7-bis(4-amidinobenzylidene)-cycloheptanone-(1); Na-tosyl-4-amidinophenylalanine piperidide; Na-naphthylsulphonylglycyl-4-amidinophenylalanine piperidide; 4-methyl-1-N.sup.2 -(methyl-1,2,3,4-tethydro-8-quinolinesulphonyl-L-arginyl-2-piperidine carbonic acid; and D-phenylalanyl-L-propyl-L-arginine chloromethyl ketone.

Nagahara et al., J. Med. Chem., vol. 37, 1200-1207(1994) describes several dibasic (amidinoaryl)propanoic acid derivatives as Factor Xa inhibitors.

Daiichi EPA 0 540 051 A1, published May 5, 1993, discloses aromatic amidine derivatives, including amidino naphthylenes, amidino-indoles, amidino-benzimidazoles, and amidino-benzothiophenes, which have Factor Xa inhibitory activity.

DuPont Merck WO 95/14683 and WO 95/14682, published Jun. 1, 1995, disclose isoxazoles and isoxaolines as antagonists of the platelet glycoprotein IIb/IIIa fibrinogen receptor. The isoxazoles and isoxaolines of WO 95/14683 are represented by the formula: ##STR2## The isoxazolines of WO 95/14682 are represented by the formula: ##STR3##

Copending, commonly assigned U.S. patent application Ser. No. 08/449597, filed May 24, 1995, discloses isoxazoline antagonists of the platelet glycoprotein IIb/IIIa fibrinogen receptor having the formula: ##STR4##

EP 53095 A and other references disclose various di-anilino-pyrazoline as components of photosensitive systems.

EP 438690 and other references disclose various 1-amido-pyrazolines as pesticides, e.g., insecticides, fungicides and acaricides.

To date there have been no isoxazoline, isothiazoline or pyrazoline derivatives described as Factor Xa inhibitors.

DETAILED DESCRIPTION OF THE INVENTION

Synthesis

The compounds of the present invention can be prepared in a number of ways well known to one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. All references cited herein are hereby incorporated in their entirety herein by reference.

A convenient method for the synthesis of the isoxazoline compounds of this invention utilizes a dipolar cycloaddition of nitrile oxides with appropriate dipolarophiles to prepare the isoxazoline rings present in compounds of Formula I (for reviews of 1,3-dipolar cycloaddition chemistry, see 1,3-Dipolar Cycloaddition Chemistry (Padwa, ed.), Wiley, New York, 1984; Kanemasa and Tsuge, Heterocycles 1990, 30, 719). Scheme 1 shows a general synthesis of 3,5-substituted-isoxazolines. An appropriately substituted hydroxylamine is treated with NCS in DMF according to the method of Liu, et al. (J. Org. Chem. 1980, 45, 3916). The resulting hydroximinoyl chloride is then dehydrohalogenated in situ using TEA to give a nitrile oxide, which undergoes a 1,3-dipolar cycloaddition to a suitably substituted alkene to afford the isoxazoline. Alternatively, the oxime may be oxidatively chlorinated, dehydrochlorinated and the resulting nitrile oxide trapped by a suitable alkene under phase transfer conditions according to the method of Lee (Synthesis 1982, 508). The isoxazoline compounds of the general formula (I) wherein the 4 and 5 positions are substituted can be prepared following the 1,3-dipolar cycloaddition methodology using a suitable 1,2-disubstituted olefin as a dipolarophile. A mixture of regioisomers is formed and the regioisomers can be separated by column chromatography. An example is shown in Scheme 2. Optically active isoxazolines can be obtained by chiral HPLC separation of the two enantiomers, or enzymatic resolution on the regioisomeric esters. It can also be obtained by the use of an appropriate chiral auxilliary on the dipolarophile as described by Olsson (J. Org. Chem. 53, 2468, 1988). The synthetic methods described above may also be used for the synthesis of compounds of this invention where Y is pyridyl or pyrimidyl derivatives in formula (I). ##STR24##

Many isoxazoline compounds of this invention can use commercially available substituted alkenes as starting materials. Compounds with R.sup.2 is acid or amide can be prepared from the commercially available alkene-esters or alkene acids. The transformations of the functional groups can be done either at the alkene stage or after the isoxazoline ring is formed. Compounds with R.sup.2 is O(CH.sub.2).sub.n R, NH(CH.sub.2).sub.n R, S(CH.sub.2).sub.n R, where R is R.sup.5 or R.sup.10, can be prepared from substituted allyl bromide. An example is shown in Scheme 3. The sulfoxides and sulfones can be prepared from oxidation of the thio-compounds (Scheme 3). Compounds wh R.sup.2 is aromatics and heteroaromatics (R.sup.10) can be prepared from the reaction of the bromide or iodide of the aromatics and hetreoaromatics with allyl of vinyl bromide. The C-linked aromatic and hetreoaromatic compounds can be synthesized using Zinc and Copper organometallics shown by Knochel (Tet. Lett. 31, 4413-4416, 1990), or using palladium-catalyzed coupling of an a-stannyl acrylate to aryl iodides or triflates by Levin (Tet. Lett. 34, 6211-6214, 1993). These reactions are exemplified in Scheme 4. The N-linked heteroaromatic compounds can be prepared by alkylation of the hetroaromatics with allyl bromides. An example is shown in Scheme 5. Compounds with R.sup.2 is COCO.sub.2 R or COCONHR can be prepared by the method discribed by Iwanowicz (Bioorg. & Med. Chem. Lett., 2, 1607-1612, 1992). ##STR25##

Appropriately substituted crotonate ester can be used as starting material for 4,5-disubstituted isoxazolines. The crotonate esters can be obtained from commertial sources or can be obtained from ethyl-4-bromocrotonate by nucleophilic displacement reactions shown in Scheme 6. Trisubstituted olefins as diplolarophiles can be obtained from ethylpropiolate by the cuprate chemistry (Scheme 7) according to the method described by Deslongchamps (Synlett, 660, 1994). ##STR26##

The isothiazoline compounds of this invention of formula (I) can be prepared by cycloaddition reaction of nitrile sulfides with olefins (Howe, J. Org. Chem., 43, 3742, 1978) as shown in Scheme 8. The nitrile sulfide is generated by thermolysis of 5-substituted 1,3,4-oxthiazol-2-one. ##STR27##

The pyrazoline compounds of this invention of formula (I) cab be prepared by the method described by Wahoff and Zahran (Synthesis, 876-879, 1987). An example of the synthesis is shown in Scheme 9. The hydrozine is coupled with the acyl chloride. The N-acylated hydrozine is reacted with dichlorotriphenylphosphorane and triethylamine. The nitrilimine generated in situ undergoes a 1,3-dipolar cycloaddition reaction with a suitable alkene to give the pyrazoline. The pyrazolines may also be prepared from isoxazolines as shown in Scheme 10. The isoxazoline was reacted with molybdenum hexacarbonyl in the conditions described by Baraldi (Synthesis, 276, 1987) provides the b-hydroxyketone. Dehydration of the b-hydroxyketone with p-toluenesulfonic acid yields the a,b-unsaturated ketone, which was then treated with hydrazine to afford the desired pyrazoline. ##STR28##

Compounds of this invention where U in formula (I) is CONH may be prepared using substituted acrylates, vinyl acetate, or crotonate as starting materials. The core ring structures can be synthesized as described above and the easter group is then coupled with an appropiate amine using standard conditions for the formation of amide bonds. The nitrile is then converted to the amidine via the imidate or thioimidate under standard conditions. Some of the compounds are prepared following the procedures described in copending commonly-assigned U.S. patent application U.S. Ser. No. 08/337920. An example of these compounds is shown in Scheme 11. The 3-substituted-isoxazoline-5-ylcarboxylic acids or 3-substituted-isoxazoline-5-ylacetic acids can be converted to the corresponding amidines first, followed by protection as the Boc-derivatives or CBZ-derivatives. They were then coupled with appropiate amines as exemplified in Scheme 12. Compounds of this invention where R.sup.1 is NHCH(NR.sup.5) in formula (I) may be prepared from amine derivatives by reaction of the amine with ethyl formimidate and N,N-dimethylpyridine in refluxing ethanol. Compounds of this invention where R.sup.1 is NHC(NR.sup.5)NR.sup.5 R.sup.6 in formula (I) may be prepared from amine derivatives by reaction of the amine with either formamidine sulfonic acid and N,N-dimethylpyridine in refluxing ethanol (Kim, et al. Tet. Lett. 29, 3183, 1988), or Bocprotected pyrazole carboxamidine in DMF (Bernatowicz et al. Tet. Lett. 34, 3389, 1993). ##STR29##

The sulfone derivatives where U is --SO.sub.2 --(CH.sub.2).sub.o -- are prepared as exemplified by the reactions in Scheme 13. Methyl (triphenylphosphoranylidene)-acetate is reacted with acetyl chloride to give the desired allene. A sulfinic acid, prepared by hydrogen peroxide oxidation of the corresponding thiol, is added into the allene to give the desired alkene (Padwa, J. Org. Chem, 54, 4232, 1989). This alkene can be used in the previously described cycloaddition reactions. The sulfonamide derviatives where U is --SO.sub.2 --NH-- are prepared as exemplified by the reactions in Scheme 14. Vinyl sulfonyl chloride is brominated, then reacted with an amine (Barnett, Tet. Lett., 651, 1968). Halogen-metal exchange and alkylation with iodoacetate gives the desired substituted vinyl sulfonamide (Stetan, Chem, Ber., 122, 169, 1889) which can be used in the previously described cycloaddition reactions. ##STR30##

Isoxazoline compounds of the general formula I wherein U is thio, sulfonyl, or sulfonamide can also be prepared by the method outlined in scheme 15. The isoxazoline thioxanthate can be converted to the sulfonylchloride by treatement with chlorine in glacial acetic acid. The sulfonylchloride is then coupled with an appropriate amine to provide the desired sulfonamide. Alternatively the thioxanthate can be hydrolysed with sodium hydroxide in ethanol to the thiol followed by traping of the intermediate thiol with an appropriate benzylbromide to afford the thioalkylphenylanalog. Oxidation of the thio-compound with MCPBA or oxone affords the sulfoxide and or sulfone. ##STR31##

Compounds of this invention where U is alkene, ether, --NHSO.sub.2 --, ans --NHCO-- can be prepared from the same intermediate as shown in Scheme 16. The 5-hydroxymethylisoxazoline is formed by the 1,3-dipolar cycloaddition described above The alcohol can be oxidized to the corresponding aldehyde aand the converted to the alkene-linked compound by Wittig reaction. The alkene-linked compounds can then be reduced to the corresponding alkyl-linked compounds. The alkyl-linked compounds can also be prepared using Zinc and Copper organometallics shown by Knochel (Tet. Lett. 31, 4413-4416, 1990, see Scheme 4), The 5-hydroxymethyl group can be converted to the azide, and then reduced to the corresponding amine. This amine intermediate is the converted to compounds with --NHSO.sub.2 --, and --NHCO-- using suitable sulfonyl or acyl chloride. The 5-hydroxymethylisoxazoline can be converted to the ether-linked compound by Mitsunobo reaction. The ether and amine linked compounds can also be prepared by displacement of the allyl bromide shown in Scheme 17. ##STR32##

Compounds of this invention where U is --CO-- can be prepared by palladium-catalyzed coupling reactions of organozinc reagents with acid chlorides (Jackson, Synlett, 819-820, 1995 and Sato, Chem. Lett., 1135, 1981) or by organimetallics of Zinc and Copper described by Knochel (J. Org. Chem. 53, 5791-5793, 1988).

Compounds of this invention where Z is absent may be prepared as shown by an example in Scheme 18. 4-Bromoaniline is protected as Boc-derivative and the coupled to 2-(t-butylamino)sulfonylphenylboronic acid under Suzuki conditions. 2-(t-Butylamino)sulfonylphenylboronic acid is prepared by the method described by Rivero (Bioorg. Med. Chem. Lett., 189, 1994). Deprotection with TFA provides the aminobiphenyl compound. The aminobiphenyl is the coupled to the core ring structures first as described above. The Bromoaniline can be linked to the core ring structures first as described above, and then undergoes Suzuki reaction to give the desired product. ##STR33##

Compounds of this invention where --Z-- is --SO.sub.2 -- are exemplified by the peperidine derivative shown in Scheme 19. Compounds of this invention where --Z-- is --NH--, --O--, and --S-- can be prepared by the methods described in Scheme 20. ##STR34##

Some of the compounds of this invention may also be prepared as shown in Scheme 21. Itaconic anhydride reacts with appropiate amine to give 3-carboxy-3-butenamide. The benzaldehyde oxime is oxidatively chlorinated and dehydrochlorinated. The resulting nitrile oxide then reacted with 3-carboxy-3-butenamide to yield the 3,5,5-trisubstituted isoxazoline which was then converted to the final benzamidine as described above. ##STR35##

Compounds of this invention where Y is a piperidine derivative in formula (I) may be prepared from piperidine alcohols which are commercially available or prepared by coupling 4-brompyridine and appropiate length acetylenic alcohol followed by reduction. The piperidine alcohol is oxidized to the corresponding aldehyde under standard conditions. The aldehyde is converted to the isoxazoline by the same methods described above. An example of such a convertion is shown in Scheme 22 where n=0-3. ##STR36##

Some of the spiro-compounds of this invention in formula (II) may be prepared as shown in Scheme 23. Itaconyl chloride is reacted with appropiate amine to give the a-methylene-succinimide which then undergos 1,3-dipolar cycloaddition to yield the spiro-isoxazoline. Some of the spiro-compounds of this invention in formula (II) may be prepared from ester or acid intermediates. An example of this transformation is shown in Scheme 23. The ester or acid group in Scheme 24 can be reduced with LiBH.sub.4 in THF or other reducing agents to give the alcohol. The alcohol is then cyclized using a mesylate intermediate to afford the desired spiro-compound. The alcohol can also be oxidized under Swern oxidation conditions to generate the corresponding aldehyde, which can cyclized to give the spiro-compound. ##STR37##

Utility

The compounds of this invention are useful as anticoagulants for the treatment or prevention of thromboembolic disorders in mammals. The term "thromboembolic disorders" as used herein includes arterial or venous cardiovascular or cerebrovascular thromboembolic disorders, including, for example, unstable angina, first or recurrent myocardial infarction, ischemic sudden death, transient ischemic attack, stroke, atherosclerosis, venous thrombosis, deep vein thrombosis, thrombophlebitis, arterial embolism, coronary and cerebral arterial thrombosis, cerebral embolism, kidney embolisms, pulmonary embolisms.

The anticoagulant effect of compounds of this invention is due to inhibition of Factor Xa. The activated factor Xa, whose major practical role is the generation of thrombin by the limited proteolysis of prothrombin, holds a central position that links the intrinsic and extrinsic activation mechanisms in the final common pathway of blood coagulation. The generation of thrombin, the final serine protease in the pathway to generate a fibrin clot, from its precursor is amplified by formation of prothrombinase complex (Factor Xa, Factor V, Ca.sup.2+ and phospholipid). Since it is calculated that one molecule of Factor Xa can generate 138 molecules of thrombin (Elodi, S., Varadi, K.: Optimization of conditions for the catalytic effect of the factor IXa-factor VIII C0omplex: Probable role of the complex in the amplification of blood coagulation. Thromb. Res. 1979, 15, 617-629), inhibition of factor Xa may be more efficient that inactivation of thrombin in interrupting the blood coagulation system.

The effectiveness of the compounds of the invention as inhibitors of Factor Xa was determined using purified human Factor Xa and synthetic substrate. The rate of Factor Xa hydrolysis of chromogenic substrate S2222 (Kabi Pharmacia, Franklin, OH) was measured both in the absence and presence of compounds of the present invention. Hydrolysis of the substrate resulted in the release of pNA, which was monitored spectrophotometrically by measuring the increase in absorbance at 405 nM. A decrease in the rate of absorbance change at 405 nm in the presence of inhibitor is indicative of enzyme inhibition. The results of this assay are expressed as inhibitory constant, K.sub.i.

Factor Xa determinations were made in 0.10 M sodium phosphate buffer, pH 7.5, containing 0.20 M NaCl, and 0.5% PEG 8000. The Michaelis constant, K.sub.m, for substrate hydrolysis was determined at 25.degree. C. using the method of Lineweaver and Burk.

Values of K.sub.i were determined by allowing 0.2-0.5 nM human Factor Xa (Enzyme Research Laboratories, South Bend, Ind.) to react with the substrate (0.20 mM-1 mM) in the presence of inhibitor. Reactions were allowed to go for 30 minutes and the velocities (rate of absorbance change vs time) were measured in the time frame of 25-30 minutes. The following relationship was used to calculate K.sub.i values. ##EQU1## where: v.sub.o is the velocity of the control in the absence of inhibitor;

v.sub.s is the velocity in the presence of inhibitor; I is the concentration of inhibitor; K.sub.i is the dissociation constant of the enzyme: inhibitor complex; S is the concentration of substrate; K.sub.m is the Michaelis constant.

The antithrombotic effect of the compounds of this invention can be demonstrated in a rat vena cava thrombosis model. In this model Male Sprague-Dawley rats weighing 350-450 grams anesthetized with a mixture of xylazine (10 mg/kg i.m.) and ketamine (110 mg/kg i.m.) are used. A carotid artery, a jugular vein and a femoral vein are cannulated for blood sampling, drug infusion and hypotonic saline injection, respectively. The abdominal vena cava is isolated and all its side-branches are ligated beneath the left renal vein. Thrombus formation is induced by rapid injection of 1 ml hypotonic saline (0.225%) into the vena cava. This is followed 15 seconds later by a 15-minute stasis of an isolated segment (about 1 cm) of the vena cava. The formed thrombus in the vena cava is removed and immediately weighed.

Test compounds or vehicle are given as continuous intravenous infusions or orally starting 1 hour before the injection of hypotonic saline. Arterial blood samples (1.5 ml) for the determination of clotting times are collected before and 1 hour after the infusion or oral dosing of test compounds or vehicle. The percentage inhibition of thrombus formation is determined for each treatment group. The ID50 values (dose which produces 50% inhibition of thrombus formation) are estimated by linear regression.

The compounds of this invention can be administered alone or in combination with one or more additional therapeutic agents. These include other anti-coagulant or coagulation inhibitory agents, anti-platelet or platelet inhibitory agents, thrombin inhibitors, or thrombolytic or fibrinolytic agents.

The compounds are administered to a mammal in a therapeutically effective amount. By "therapeutically effective amount" is meant an amount of a compound of Formula I that, when administered alone or in combination with an additional therapeutic agent to a mammal, is effective to prevent or ameliorate the thromboembolic disease condition or the progression of the disease.

By "administered in combination" or "combination therapy" is meant that the compound of Formula I and one or more additional therapeutic agents are administered concurrently to the mammal being treated. When administered in combination each component may be administered at the same time or sequentially in any order at different points in time. Thus, each component may be administered separately but sufficiently closely in time so as to provide the desired therapeutic effect.

Other anticoagulant agents (or coagulation inhibitory agents) that may be used in combination with the compounds of this invention include warfarin and heparin, as well as other Factor Xa inhibitors such as those described in the publications identified above under Background of the Invention.

The term anti-platelet agents (or platelet inhibitory agents), as used herein, denotes agents that inhibit platelet function such as by inhibiting the aggregation, adhesion or granular secretion of platelets. Such agents include the various known non-steroidal anti-inflammatory drugs (NSAIDS) such as aspirin, ibuprofen, naproxen, sulindac, indomethacin, mefenamate, droxicam, diclofenac, sulfinpyrazone, and piroxicam, including pharmaceutically acceptable salts or prodrugs thereof. Of the NSAIDS, aspirin (acetylsalicyclic acid or ASA), and piroxicam. Other suitable anti-platelet agents include ticlopidine, including pharmaceutically acceptable salts or prodrugs thereof. Ticlopidine is also a preferred compound since it is known to be gentle on the gastro-intestinal tract in use. Still other suitable platelet inhibitory agents include thromboxane-A2-receptor antagonists and thromboxane-A2-synthetase inhibitors, as well as pharmaceutically acceptable salts or prodrugs thereof.

The term thrombin inhibitors (or anti-thrombin agents), as used herein, denotes inhibitors of the serine protease thrombin. By inhibiting thrombin, various thrombin-mediated processes, such as thrombin-mediated platelet activation (that is, for example, the aggregation of platelets, and/or the granular secretion of plasminogen activator inhibitor-1 and/or serotonin) and/or fibrin formation are disrupted. Such inhibitors include boroarginine derivatives and boropeptides, hirudin and argatroban, including pharmaceutically acceptable salts and prodrugs thereof. Boroarginine derivatives and boropeptides include N-acetyl and peptide derivatives of boronic acid, such as C-terminal a-aminoboronic acid derivatives of lysine, ornithine, arginine, homoarginine and corresponding isothiouronium analogs thereof. The term hirudin, as used herein, includes suitable derivatives or analogs of hirudin, referred to herein as hirulogs, such as disulfatohirudin. Boropeptide thrombin inhibitors include compounds described in Kettner et al., U.S. Pat. No. 5,187,157 and European Patent Application Publication Number 293 881 A2, the disclosures of which are hereby incorporated herein by reference. Other suitable boroarginine derivatives and boropeptide thrombin inhibitors include those disclosed in PCT Application Publication Number 92/07869 and European Patent Application Publication Number 471 651 A2, the disclosures of which are hereby incorporated herein by reference, in their entirety.

The term thrombolytics (or fibrinolytic) agents (or thrombolytics or fibrinolytics), as used herein, denotes agents that lyse blood clots (thrombi). Such agents include tissue plasminogen activator, anistreplase, urokinase or streptokinase, including pharmaceutically acceptable salts or prodrugs thereof. The term anistreplase, as used herein, refers to anisoylated plasminogen streptokinase activator complex, as described, for example, in European Patent Application No. 028,489, the disclosures of which are hereby incorporated herein by reference herein, in their entirety. The term urokinase, as used herein, is intended to denote both dual and single chain urokinase, the latter also being referred to herein as prourokinase.

Administration of the compounds of Formula I of the invention in combination with such additional therapeutic agent, may afford an efficacy advantage over the compounds and agents alone, and may do so while permitting the use of lower doses of each. A lower dosage minimizes the potential of side effects, thereby providing an increased margin of safety.

The compounds of the present invention are also useful as standard or reference compounds, for example as a quality standard or control, in tests or assays involving the inhibition of Factor Xa. Such compounds may be provided in a commercial kit, for example, for use in pharmaceutical research involving Factor Xa. The compounds of the present invention may also be used in diagnostic assays involving Factor Xa.

Dosage and Formulation

The compounds of this invention can be administered in such oral dosage forms as tablets, capsules (each of which includes sustained release or timed release formulations), pills, powders, granules, elixirs, tinctures, suspensions, syrups, and emulsions. They may also be administered in intravenous (bolus or infusion), intraperitoneal, subcutaneous, or intramuscular form, all using dosage forms well known to those of ordinary skill in the pharmaceutical arts. They can be administered alone, but generally will be administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice.

The dosage regimen for the compounds of the present invention will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the species, age, sex, health, medical condition, and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; the route of administration, the renal and hepatic function of the patient,and the effect desired. A physician or veterinarian can determine and prescribe the effective amount of the drug required to prevent, counter, or arrest the progress of the thromboembolic disorder.

By way of general guidance, the daily oral dosage of each active ingredient, when used for the indicated effects, will range between about 0.001 to 1000 mg/kg of body weight, preferably between about 0.01 to 100 mg/kg of body weight per day, and most preferably between about 1.0 to 20 mg/kg/day. Intravenously, the most preferred doses will range from about 1 to about 10 mg/kg/minute during a constant rate infusion. Compounds of this invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily.

Compounds of this invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal routes, using transdermal skin patches. When administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.

The compounds are typically administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as pharmaceutical carriers) suitably selected with respect to the intended form of administration, that is, oral tablets, capsules, elixirs, syrups and the like, and consistent with conventional pharmaceutical practices.

For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic, pharmaceutically acceptable, inert carrier such as lactose, starch, sucrose, glucose, methyl callulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, sorbitol and the like; for oral administration in liquid form, the oral drug components can be combined with any oral, non-toxic, pharmaceutically acceptable inert carrier such as ethanol, glycerol, water, and the like. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents, and coloring agents can also be incorporated into the mixture. Suitable binders include starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth, or sodium alginate, carboxymethylcellulose, polyethylene glycol, waxes, and the like. Lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum, and the like.

The compounds of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, and multilamellar vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine, or phosphatidylcholines.

Compounds of the present invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol, polyhydroxyethylaspartamidephenol, or polyethyleneoxidepolylysine substituted with palmitoyl residues. Furthermore, the compounds of the present invention may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, polylactic acid, polyglycolic acid, copolymers of polylactic and polyglycolic acid, polyepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacylates, and crosslinked or amphipathic block copolymers of hydrogels.

Dosage forms (pharmaceutical compositions) suitable for administration may contain from about 1 milligram to about 100 milligrams of active ingredient per dosage unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.5-95% by weight based on the total weight of the composition.

Gelatin capsules may contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract.

Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.

In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben, and chlorobutanol.

Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences, Mack Publishing Company, a standard reference text in this field.

Representative useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows:

Capsules

A large number of unit capsules are prepared by filling standard two-piece hard gelatin capsules each with 100 milligrams of powdered active ingredient, 150 milligrams of lactose, 50 milligrams of cellulose, and 6 milligrams magnesium stearate.

Soft Gelatin Capsules

A mixture of active ingredient in a digestable oil such as soybean oil, cottonseed oil or olive oil is prepared and injected by means of a positive displacement pump into gelatin to form soft gelatin capsules containing 100 milligrams of the active ingredient. The capsules are washed and dried.

Tablets

A large number of tablets are prepared by conventional procedures so that the dosage unit is 100 milligrams of active ingredient, 0.2 milligrams of colloidal silicon dioxide, 5 milligrams of magnesium stearate, 275 milligrams of microcrystalline cellulose, 11 milligrams of starch and 98.8 milligrams of lactose. Appropriate coatings may be applied to increase palatability or delay absorption.

Injectable

A parenteral composition suitable for administration by injection is prepared by stirring 1.5% by weight of active ingredient in 10% by volume propylene glycol and water. The solution is made isotonic with sodium chloride and sterilized.

Suspension

An aqueous suspension is prepared for oral administration so that each 5 mL contain 100 mg of finely divided active ingredient, 200 mg of sodium carboxymethyl cellulose, 5 mg of sodium benzoate, 1.0 g of sorbitol solution, U.S.P., and 0.025 mL of vanillin.

Where the compounds of this invention are combined with other anticoagulant agents, for example, a daily dosage may be about 0.1 to 100 milligrams of the compound of Formula I and about 1 to 7.5 milligrams of the second anticoagulant, per kilogram of patient body weight. For a tablet dosage form, the compounds of this invention generally may be present in an amount of about 5 to 10 milligrams per dosage unit, and the second anti-coagulant in an amount of about 1 to 5 milligrams per dosage unit.

Where the compounds of Formula I are administered in combination with an anti-platelet agent, by way of general guidance, typically a daily dosage may be about 0.01 to 25 milligrams of the compound of Formula I and about 50 to 150 milligrams of the anti-platelet agent, preferably about 0.1 to 1 milligrams of the compound of Formula I and about 1 to 3 milligrams of antiplatelet agents, per kilogram of patient body weight.

Where the compounds of Formula I are adminstered in combination with thrombolytic agent, typically a daily dosage may be about 0.1 to 1 milligrams of the compound of Formula I, per kilogram of patient body weight and, in the case of the thrombolytic agents, the usual dosage of the thrombolyic agent when administered alone may be reduced by about 70-80% when administered with a compound of Formula I.

Where two or more of the foregoing second therapeutic agents are administered with the compound of Formula I, generally the amount of each component in a typical daily dosage and typical dosage form may be reduced relative to the usual dosage of the agent when administered alone, in view of the additive or synergistic effect of the therapeutic agents when administered in combination.

Particularly when provided as a single dosage unit, the potential exists for a chemical interaction between the combined active ingredients. For this reason, when the compound of Formula I and a second therapeutic agent are combined in a single dosage unit they are formulated such that although the active ingredients are combined in a single dosage unit, the physical contact between the active ingredients is minimized (that is, reduced). For example, one active ingredient may be enteric coated. By enteric coating one of the active ingredients, it is possible not only to minimize the contact between the combined active ingredients, but also, it is possible to control the release of one of these components in the gastrointestinal tract such that one of these components is not released in the stomach but rather is released in the intestines. One of the active ingredients may also be coated with a material which effects a sustained-release throughout the gastrointestinal tract and also serves to minimize physical contact between the combined active ingredients. Furthermore, the sustained-released component can be additionally enteric coated such that the release of this component occurs only in the intestine. Still another approach would involve the formulation of a combination product in which the one component is coated with a sustained and/or enteric release polymer, and the other component is also coated with a polymer such as a lowviscosity grade of hydroxypropyl methylcellulose (HPMC) or other appropriate materials as known in the art, in order to further separate the active components. The polymer coating serves to form an additional barrier to interaction with the other component.
