Amidinophenyl-pyrrolidines, -pyrrolines, and -isoxazolidines and derivatives thereof

FIELD OF THE INVENTION
This invention relates generally to amidinophenyl pyrrolidines, -pyrrolines, and -isoxazolidines and derivatives which are inhibitors of trypsin-like serine protease enzymes, especially factor Xa, pharmaceutical compositions containing the same, and methods of using the same as anticoagulant agents for treatment and prevention of thromboembolic disorders.
BACKGROUND OF THE INVENTION
Himmelsbach et al in CA 2,054,850 discuss aggregation inhibiting compounds of the formula:
B--X--A--Y--E
wherein A may be a cyclic imino such as pyrrolidine and amidst the various definitions of B and X one can find amidino and arylene listed. The combination of Y--E, however, is not considered to be useful for the present invention. Thus, the compounds of Himmelsbach et al differ from those of the present invention. Moreover, inhibition of factor Xa is not discussed in Himmelsbach et al as a use for the compounds of the above formula.
In U.S. Pat. No. 5,463,071, Himmelsbach et al depict cell aggregation inhibitors which are 5-membered heterocycles of the formula: ##STR2## wherein the heterocycle is other than pyrroline and pyrrolidine and groups A--B--C-- and F--E--D-- are attached to the ring system. A--B--C-- can be a wide variety of substituents including a basic group attached to an aromatic ring. The F--E--D-- group, however, would appear to be an acidic functionality which differs from the present invention. Furthermore, use of these compounds as inhibitors of factor Xa is not discussed.
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 Complex: 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 than inactivation of thrombin in interrupting the blood coagulation system.
Therefore, efficacious and specific inhibitors of factor Xa are needed as potentially valuable therapeutic agents for the treatment of thromboembolic disorders. It is thus desirable to discover new factor Xa inhibitors.
SUMMARY OF THE INVENTION
Accordingly, one object of the present invention is to provide novel amidino-phenylpyrrolidines and analogs thereof which are useful as factor Xa inhibitors or pharmaceutically acceptable salts or prodrugs thereof.
It is another object of the present invention to provide pharmaceutical compositions comprising a pharmaceutically acceptable carrier and a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form thereof.
It is another object of the present invention to provide a method for treating thromboembolic disorders comprising administering to a host in need of such treatment a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form thereof.
These and other objects, which will become apparent during the following detailed description, have been achieved by the inventors' discovery that compounds of formula (I): ##STR3## or pharmaceutically acceptable salt or prodrug forms thereof, wherein A, B, D, D.sup.a, J, m, n, R, R.sup.a, R.sup.b and Z are defined below, are effective factor Xa inhibitors.

DEFINITIONS
The compounds herein described may have asymmetric centers. Compounds of the present invention containing an asymmetrically substituted atom may be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis from optically active starting materials. Many geometric isomers of olefins, C.dbd.N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomeric form is specifically indicated.
The term "substituted," as used herein, means that any one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substitent is keto (i.e., .dbd.O), then 2 hydrogens on the atom are replaced.
When any variable (e.g., R.sup.6) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 R.sup.6, then said group may optionally be substituted with up to two R.sup.6 groups and R.sup.6 at each occurrence is selected independently from the definition of R.sup.6. Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.
When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

As used herein, "pharmaceutically acceptable salts" refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic, and the like.

"Stable compound" and "stable structure" are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.
SYNTHESIS
The compounds of the present invention can be prepared in a number of ways 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 by variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention. It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene and Wuts (Protective Groups In Organic Synthesis, Wiley and Sons, 1991). All references cited herein are hereby incorporated in their entirety herein by reference.
The compounds of the present invention represented by Formula I are 1,3,4-trisubstituted and 1,3,3,4-tetrasubstituted pyrrolidines, 1,3,4-trisubstituted .DELTA..sup.3 -pyrrolines, and 2,4,5-trisubstituted, 2,4,4,5-tetrasubstituted and 2,4,5,5-tetrasubstituted isoxazolidines. A convenient method for the preparation of these heterocycles utilizes a 1,3-dipolar cycloaddition of an appropriate 1,3-dipole with an appropriate dipolarophile. To prepare the pyrrolidine nucleus, the appropriate 1,3-dipole is an azomethine ylide. To prepare the isoxazolidine nucleus the appropriate 1,3-dipole is a nitrone (for reviews of 1,3-dipolar cycloaddition chemistry of azomethine ylides and nitrones, see 1,3-Dipolar Cycloaddition Chemistry (A. Padwa, Ed.), Wiley-Interscience, New York, 1984; Tsuge and Kanemasa, in Advances in Heterocyclic Chemistry (A. Katritzky, Ed.), 1989, 45, p. 232; Torssell, in Nitrile Oxides, Nitrones and Nitronates in Organic Synthesis, VCh Publishers, Inc., New York, 1988; Breuer, Aurich and Nielsen, in Nitrones, Nitronates, and Nitroxides, Wiley, New York, 1989).
Although there are several methods known in the literature for generating stabilized azomethine ylides, fewer methods are available for generating the non-stabilized azomethine ylides required for the preparation of the pyrrolidine-containing compounds of the present invention. However, the decomposition of an appropriately substituted tertiary amine was found to be a suitable method for the purposes of the present invention. A general scheme for the generation and reaction of non-stabilized azomethine ylides using this method is shown in Scheme 1. The azomethine ylide precursors 1a and 1b are either commercially available or are readily prepared by methods known to those skilled in the art. Shown at the bottom of Scheme 1 are some preferred methods beginning with the readily available secondary amines 4 (Hosomi et al Chem. Letters 1984, 1117; Padwa et al. J. Org. Chem. 1985, 50, 4006). Treatment of 4 with aqueous formaldehyde in the presence of either methanol or potassium cyanide at near neutral pH generates the tertiary amines 1a and 1b, respectively. Alternatively, the anion of 4 can be generated with a suitable base, such as n-butyllithium or sodium hydride, and alkylated with chloromethyl methyl ether to generate 1a. The substituent R' can be benzyl, substituted benzyl, aikyl, cycloalkyl, etc., but preferably is benzyl. ##STR9##
The generation of the azomethine ylide 2 from 1a and 1b is straightforward. Treatment of 1a with a number of acidic catalysts, such as trifluoroacetic acid, acetic acid, titanium tetrachloride or trifluoromethanesulfonic acid, causes its rapid decomposition to the azomethine ylide 2 (Terao et al Chem. Pharm. Bull. 1985, 33, 2762). The preferred catalyst is 5-25% trifluoroacetic acid in dichloromethane solvent. Treatment of 1b with silver fluoride in the dark also generates 2 (Padwa et al. J. Org. Chem. 1985, 50, 4006). This method relies on the silylophilic nature of fluoride ion and is generally carried out in acetonitrile solvent. Once generated, the non-stabilized azomethine ylide 2 reacts with olefins to produce pyrrolidines 3 by 1,3-dipolar cycloaddition. Generally the olefin needs to be activated by a suitable electron withdrawing group, such as carboxylic ester, carboxylic amide, ketone, nitrile, sulfone, nitro, etc. Styrenes which are substituted with electron withdrawing groups, such as carboxylic ester, carboxylic amide, ketone, nitrile, sulfone, nitro, etc., also are able to undergo reaction with 2 to produce aryl-substituted pyrrolidines. The 1,3-dipolar cycloaddition is stereospecific in that the stereochemistry of the olefin is retained and translated into the relative stereochemistry of the pyrrolidine product. Thus, trans-disubstituted olefins undergo cyclization to produce pyrrolidines 3 with a trans configuration of the 3,4-substituents on the pyrrolidine ring.
In Scheme 2 is shown how the just described 1,3-dipolar cycloaddition can be applied to the synthesis of the 1,3,4-trisubstituted and 1,3,3,4-tetrasubstituted pyrrolidine nucleus contained in the compounds of the present invention. The required di- or trisubstituted olefins 6 are readily available from cyanobenzaldehydes 5 by reaction with stabilized Wittig reagents or with the sodium or potassium anions of phosponate reagents. The stabilized Wittig reagents react with 5 to give E-disubstituted olefins 6 (R.sup.c =hydrogen, R.sup.a =carbomethoxy, acetyl). The phosphonate anions also give E-di- or trisubstituted olefins 6 when R.sup.c of the phosphonate is hydrogen or methyl, R.sup.a is carbomethoxy or carboethoxy and R.sup.d is methyl or ethyl. Modification of the phosphonate also allows for the preparation of the Z-disubstituted olefins 6. Thus, treatment of bis(2,2,2-trifluoroethyl)(methoxycarbonylmethyl)phosphonate (R.sup.d =--CH.sub.2 CF.sub.3) with potassium bis(trimethylsilyl)amide and 18-crown-6 generates a potassium anion of the phosphonate that reacts with 5 to give selectively the Z-disubstituted 6 where R.sup.c is carbomethoxy and R.sup.a is hydrogen. ##STR10##
The 1,3-dipolar cycloaddition of olefins 6 with N-benzyl derivatives of 7 under TFA catalysis smoothly affords the pyrrolidines 8. The relative stereochemistry about the pyrrolidine ring is determined by the geometry of the olefin 6 as described in connection with Scheme 1. Deprotection of the N-benzyl group (R.sup.e, R.sup.f =hydrogen) can be accomplished in several ways. Two preferred methods are catalytic hydrogenation in the presence of di-tert-butyl dicarbonate followed by trifluoroacetic acid deprotection of the N-tert-butyl carbamate intermediate. This procedure affords 9 as the trifluoroacetic acid salt. Another method involves refluxing 8 in the presence of .alpha.chloroethyl chloroformate in a solvent such as 1,2-dichloroethane followed by refluxing in methanol to deprotect the .alpha.chloroethyl carbamate intermediate (Olofson et al J. Org. Chem. 1984, 49, 2081). This methods affords 9 as the hydrochloride salt.
In Scheme 3 is shown how to prepare compounds of Formula I in which J is CO, SO.sub.2 or CO.sub.2 attached to the pyrrolidine nucleus. Where J in Formula I is CO, the compounds can be prepared by two preferred methods. The first is the reaction of the pyrrolidine 9 with an acid chloride in the presence of a suitable base such as triethylamine. In cases where the required acid chloride is not commercially available, it can be prepared from the corresponding carboxylic acid by treatment with thionyl chloride or other methods known to those skilled in the art. Alternatively, the pyrrolidine 9 can be coupled to a carboxylic acid using any of a number of peptide coupling methods (mixed anhydride, HBTU, DCC, etc.) well known to those skilled in the art of organic synthesis. The product of these methods is the amide 10. To prepare the carbamate compounds 11, where J in Formula I is CO.sub.2, the pyrrolidine 9 can be coupled to the appropriate chloroformate or succinimidyl carbonate in the presence of an appropriate base such as triethylamine. The compounds of Formula I where J is SO.sub.2 can be prepared from pyrrolidine 9 by treatment with the appropriate sulfonyl chloride to afford the sulfonamides 12. In cases where the sulfonyl chloride is not commercially available, it can be prepared from the corresponding sulfonic acid 13 using phosphorous pentachloride or thionyl chloride. Where the sulfonic acid 13 is not commercially available, it can be prepared from the corresponding bromide 14 by displacement with sodium sulfite.
To prepare compounds where J in Formula I is CH.sub.2, a simple alkylation of the pyrrolidine 9 with the appropriate primary alkyl bromide or chloride in the presence of a base such as triethylamine can provide the required compounds. ##STR11##
To prepare pyrrolidine-containing compounds of Formula I where A-B is a biphenyl residue, the chemistry described in Scheme 4 can be used. For compounds where --J(CH.sub.2).sub.n -- is CH.sub.2 the preferred method involves preparing the bromo-containing reagent 15 through alkylation of trimethylsilylmethylamine followed by reaction of the resulting secondary amine with aqueous formaldehyde in methanol as described previously. Other methods known to those skilled in the art can be envisioned to prepare this compound. The 1,3-dipolar cycloaddition described earlier with olefin 6 affords the pyrrolidine 16. The biphenyl residue can be constructed using the palladium-catalyzed Suzuki coupling of 16 with an appropriate arylboronic acid (Miyaura et al Syn. Comm. 1981, 11, 513). The product from the Suzuki coupling is the biphenyl compound 17. The arylboronic acid can be prepared from the corresponding arylbromide by transmetallation to the aryllithium reagent with n-butyllithium or t-butyllithium followed by reaction with trimethylborate and hydrolysis to the boronic acid. ##STR12##
Compounds containing different J--(CH.sub.2).sub.n -- groups such as 18, which are available following the procedures described in Scheme 3, can be transformed in an analogous fashion into the corresponding biphenyl-containing pyrrolidine compounds 19.
Scheme 5 describes methods used to elaborate the R--(CH.sub.2).sub.m -- group of Formula I in the pyrrolidine series of compounds. Compound 20 (m=0) is obtainable by the procedures described in earlier schemes. Compound 20 (m=1) is a one carbon homolog which can be prepared from the appropriate 20 (m=0) analog by homologation procedures known to those skilled in the art of organic chemistry. To prepare carboxylic amide analogs, the ester 20 is first hydrolyzed to the carboxylic acid and then is converted to the desired amide 21 by any of a variety of procedures known to those skilled in the art, such as the mixed anhydride method, DCC-mediated coupling, etc. Alcohol derivatives are available by reduction of the carboxylic acid derived from 20 by either borane tetrahydrofuran complex or by a procedure involving sodium borohydride reduction of the mixed anhydride of the carboxylic acid. The ether derivatives 23 are readily available by etherification of the alcohol 22 with an alkyl halide and a suitable base such as sodium hydride. The alcohol 22 can also be transformed into the thioether derivatives by first converting the alcohol into a good leaving group, for example by converting it into its mesylate or tosylate with the appropriate sulfonyl chloride and a base such as pyridine or triethylamine. Displacement of the leaving group with a thiol in the presence of a base will then yield the thioether derivatives 24. Oxidation of 24 by any of a variety of well know oxidizing agents can then afford the corresponding sulfone derivatives 25. ##STR13##
All of the pyrrolidine derivatives described in Schemes 2-5 contain an aromatic cyano group which must be converted to its amidine derivative to prepare the final compounds described by Formula I. Generally, in the course of preparing the compounds of this present invention, this conversion has been the final step in each synthetic sequence and it is shown in Scheme 6. The preferred method was first described by Pinner and Klein (Ber., 1877, 10, 1889; for a more recent review see: Decroix, J. Chem. Res., 1978, 134). By this method the nitrile 26 is dissolved in an anhydrous alcohol or a mixture of at least one equivalent of an alcohol and an anhydrous aprotic cosolvent, such as chloroform or an acetate ester of the selected alcohol (i.e., methyl acetate for methyl alcohol). Typically, this mixture is cooled to below ambient temperature and dry hydrogen chloride gas is added via a gas dispersion tube until the solvent is saturated with HCl. The mixture is then sealed and stirred at ambient temperature or below to form an intermediate imidate. The imidate is isolated and dissolved in an anhydrous alcohol solvent and treated with ammonia, ammonium carbonate, ammonium acetate or alcoholic ammonia solution to afford the desired amidine 27. These compounds are conveniently purified by preparative reverse phase HPLC or by recrystallization to give the pyrrolidine compounds defined by Formula I. ##STR14##
In cases where A or B in compound 26 is substituted with a tert-butylsulfonamide group, the tert-butyl protecting group can be removed by refluxing in trifluoroacetic acid prior to subjecting these compounds to the Pinner sequence.
Although the Pinner sequence to produce the amidines 27 is generally the final step in the preparation of the pyrrolidine compounds of Formula I, some transformations can be carried out on the amidine derivatives themselves, as shown in Scheme 7. To prepare the carboxylic acid derivatives of the present invention, the methyl ester 28 can be treated with an excess of lithium hydroxide in aqueous tetrahydrofuran to afford the acid 29. To prepare esters other than methyl esters, the methyl ester 28 can be treated at reflux with an excess of another alcohol, such as isopropanol or n-butanol, in the presence of a catalytic amount of a titanium (IV) tetraalkoxide, such as titanium (IV) tetraisopropoxide. This reaction produces the alternate ester 30. Due to the large excess of alcohol used, the titanium reagent does not have to match the alcohol, thus reaction of 28 with excess n-butanol in the presence of catalytic titanium (IV) tetraisopropoxide produces the n-butyl ester derivative of 30. ##STR15##
The syntheses of the pyrrolidine compounds described in the preceeding schemes were all described for racemic compounds, despite the presence of one or more chiral centers in all of the compounds presented. It is also possible to prepare many of the pyrrolidine compounds contained in this invention as single enantiomers in a well-defined manner by asymmetric synthesis. Presumably many of the compounds would also be amenable to resolution methods to prepare single enantiomers. In Scheme 8 is described a method for the asymmetric synthesis of the pyrrolidine compounds of this invention. The preferred, but not the only, method for preparing single enantiomers of these compounds is by employing a 1,3-dipolar cycloaddition of an azomethine ylide with an olefin derivative which contains a chiral auxiliary to induce asymmetry. Although there are many chiral auxiliaries which would presumably be capable of inducing an enantioselective 1,3-dipolar cycloaddition, preferred auxiliaries are (1S)-(-)-2,10-camphorsultam and (1R)-(+)-2,10-camphorsultam, both of which are commercially available. A preferred, but not the only, method of introducing the camphorsultam auxiliary is by reaction of the aluminum reagent derived from the auxiliary 32 with an ester 31 to give the amide 33. The reaction of 33 with the azomethine ylide precursor described earlier in the presence of trifluoroacetic acid results in a 1,3-dipolar cycloaddition to give a mixture of diastereomeric pyrrolidines 34 and 35 (Fevig, Bioorg. Med. Chem. Lett. 1996, 6, 295). The diastereomers can be separated by flash chromatography and separately elaborated to enantiomerically pure pyrrolidine compounds of Formula I. The removal of the camphorsultam chiral auxiliary can be accomplished by two preferred methods. The first involves treating the cycloaddition product with lithium hydroxide in aqueous tetrahydrofuran which furnishes the carboxylic acid 36, which can be transformed into the corresponding methyl ester 37 by a variety of methods known to those skilled in the art. Additionally, the cycloaddition product can be treated with methanolic magnesium methoxide to afford the corresponding methyl ester 37 directly. The enantiomerically pure methyl esters 37 can be elaborated to enantiomerically pure pyrrolidine-containing compounds of Formula I by the procedures described in Schemes 2-7. ##STR16##
The isoxazolidine-containing compounds of the present invention are preferably prepared by the 1,3-dipolar cycloaddition of an appropriate nitrone with an appropriate dipolarophile, as described earlier. Although there are several methods known in the literature for the generation of nitrone intermediates, a preferred method for generating the compounds of the present invention is shown in Scheme 9. In this method the nitrone is generated from the hydroxyl amine 38 by treatment with paraformaldehyde with concurrent removal of water (Wityak et al J. Org. Chem. 1987, 52, 2179). This is conveniently accomplished by refluxing the reaction mixture (to crack the paraformaldehyde polymer) in a solvent such as benzene in the presence of a drying agent such as crushed activated molecular sieves to remove water produced in the reaction. The nitrone 39 thus generated reacts with a variety of olefins to produce the regioisomeric isoxazolidines 40 and 41. ##STR17##
The R' group on 38 can be hydrogen, alkyl, alkylaryl, aryl, etc. The reaction is stereospecific in that the geometry of the olefin is translated into the relative stereochemistry of the cycloaddition product, as is the case for the azomethine ylide 1,3-dipolar cycloadditions discussed earlier. Thus, an E-disubstituted olefin (R.sup.c =H, R.sup.b,R.sup.a =substituents) gives rise to isoxazolidines 40 and 41 having a trans relationship between R.sup.a and R.sup.b. The regioselectivity of the cycloaddition is dependent on the nature and substitution pattern of the olefin. In some cases mixtures of 40 and 41 are produced while in other cases a certain olefin will result in a regioselective reaction and give rise to only 40 or 41.
Much of the chemistry described for the pyrrolidine compounds in Schemes 2-8 can also be applied to the isoxazolidine compounds. In Scheme 10 is shown how the just described nitrone 1,3-dipolar cycloaddition can be applied to the synthesis of the 2,4,5-trisubstituted, 2,4,4,5-tetrasubstituted and 2,4,5,5-tetrasubstituted isoxazolidines contained in the compounds of the present invention in which A-B of Formula I is a biphenyl residue and J(CH.sub.2).sub.n is CH.sub.2. The preferred, but not the only, method for preparing compounds of this type is to prepare the appropriate 4-bromobenzylhydroxylamine 43 from the corresponding 4-bromobenzaldehyde 42. This is readily accomplished by standard formation of the oxime by standard methods, followed by reduction of the oxime to give 43. This reduction can be accomplished with borane-pyridine complex under acidic conditions or with sodium cyanoborohydride under acidic conditions. ##STR18##
Generation of the nitrone with paraformaldehyde as described in Scheme 9 and reaction with the appropriate olefinic benzonitrile 44 leads to a regioisomeric mixture of isoxazolidines 45a and 45b. Suzuki coupling of 45a and 45b with the appropriate boronic acid, as described in Scheme 4, gives the isoxazolidines 46a and 46b. The amidine compounds 47a and 47b, corresponding to compounds described by Formula I, can be prepared by the Pinner protocol as described in Scheme 6.
To prepare isoxazolidine compounds of Formula I where J(CH.sub.2).sub.n is other than CH.sub.2 (J(CH.sub.2).sub.n =(CH.sub.2).sub.n, SO.sub.2 (CH.sub.2).sub.n, CO(CH.sub.2).sub.n, CO.sub.2 (CH.sub.2).sub.n, etc.) the methods described in Scheme 11 can be used. Generation of the nitrone 49 can be accomplished by treatment of hydroxylamine hydrochloride 48 with paraformaldehyde as described in Scheme 9. Reaction of 49 with an olefin 6 can afford the N-unsubstituted regioisomeric isoxazolidines 50a and 50b. Treatment of 50a and 50b with compounds of type 51 can be used to prepare a variety of N-substituted isoxazolidines 52a and 52b. Compounds 51 can include alkyl halides (LG=Br, Cl; J=CH.sub.2), sulfonyl chlorides (LG=Cl; J=SO.sub.2), carboxylic acids (LG=OH; J=CO), carboxylic acid chlorides (LG=Cl; J=CO) and chloroformates (LG=Cl; J=CO.sub.2). The reaction conditions to afford N-substituted isoxazolidines 52a and 52b can be those described in Scheme 3 for the pyrrolidine compounds or other procedures known to those skilled in the art of organic chemistry. The products 52 can be carried onto the final products described by Formula I following procedures described for the pyrrolidines in Schemes 4-8. ##STR19##
In Scheme 12 is shown how the previously described 1,3-dipolar cycloaddition can be applied to the synthesis of the 1,3,4-trisubstituted .DELTA..sup.3 -pyrroline nucleus contained in compounds of the present invention. The required dipolarophile for .DELTA..sup.3 -pyrroline synthesis is an alkyne such as 54. These compounds can best be prepared by a variety of palladium-catalyzed aryl-alkyne coupling reactions. Two such examples are shown in Scheme 12. In one case an alkynylzinc species of an appropriate substituted alkyne is generated with n-BuLi and zinc chloride. This species is then coupled to the appropriate aryl halide or aryl triflate 53 in the presence of a palladium (II) catalyst to give alkyne 54. Alternatively, the aryl halide or aryl triflate 53 can be coupled to an appropriate substituted alkyne in the presence of a palladium (0) catalyst, copper iodide and an organic amine base to give 54. Other procedures to produce 54 are available and known to those skilled in the art. Reaction of 7 with alkyne 54, in which R.sup.a is an electron-withdrawing group such as a carboxylic ester, carboxylic amide, ketone, nitrile, sulfone, nitro, etc., should produce the desired .DELTA..sup.3 -pyrroline 55. The N-benzyl group can readily be removed by the 1-chloroethyl chloroformate procedure described in Scheme 1 to afford the .DELTA..sup.3 -pyrroline nucleus 56. ##STR20##
In Scheme 13 is shown how to prepare compounds of Formula I in which R is COR.sup.d, CO.sub.2 R.sup.d, SO.sub.2 R.sup.d or R.sup.d attached to the pyrrolidine or .DELTA..sup.3 -pyrroline nitrogen, where R.sup.d is alkyl, aryl or alkylaryl. Where R in Formula I is COR.sup.d, the compounds can be prepared by two preferred methods. The first is the reaction of the pyrrolidine or .DELTA..sup.3 -pyrroline 57 with an acid chloride in the presence of a suitable base such as triethylamine. In cases where the required acid chloride is not commercially available, it can be prepared from the corresponding carboxylic acid by treatment with thionyl chloride or other methods known to those skilled in the art. Alternatively, the pyrrolidine or .DELTA..sup.3 -pyrroline 57 can be coupled to a carboxylic acid using any of a number of peptide coupling methods (mixed anhydride, HBTU, DCC, etc.) well known to those skilled in the art of organic synthesis. The product of these methods is amide 58. To prepare carbamate compounds 59, where R in Formula I is CO.sub.2 R.sup.d, the pyrrolidine or .DELTA..sup.3 -pyrroline 57 can be coupled to the appropriate chloroformate or succinimidyl carbonate in the presence of an appropriate base such as triethylamine. The compounds of Formula I where R is SO.sub.2 R.sup.d can be prepared from pyrrolidine or .DELTA..sup.3 -pyrroline 57 by treatment with the appropriate sulfonyl chloride to afford the sulfonamides 60. In cases where the sulfonyl chloride is not commercially available, it can be prepared from the corresponding sulfonic acid 62 using phosphorous pentachloride or thionyl chloride. Where the sulfonic acid 62 is not commercially available, it can be prepared from the corresponding bromide 61 by displacement with sodium sulfite. To prepare compounds where R in Formula I is R.sup.d, a simple alkylation of the pyrrolidine or .DELTA..sup.3 -pyrroline 57 with the appropriate primary alkyl bromide, chloride or tosylate in the presence of a base such as triethylamine can provide the required compounds (Formula I, R=R.sup.d). ##STR21##
The compounds of Formula I contain a linking group Z connecting the pyrrolidine and .DELTA..sup.3 -pyrroline rings to the A-B moiety. In Schemes 14-17 is shown how the various linking groups can be synthesized and incorporated into the structures of Formula Ib. It will be appreciated by those skilled in the art of organic synthesis that depending on the groups R and A-B of Formula Ib, some modification of reaction order or use of suitable protecting groups may be required to prepare the desired compounds. Many of the various linking groups can be derived from a carboxylic ester group when the azomethine ylide cyclizations of Scheme 2 are carried out on dipolarophiles 6 in which R.sup.a or R.sup.c is a carboxylic ester or when those of Scheme 3 are carried out on dipolarophiles 54 in which R.sup.a is a carboxylic ester. For compounds of Formula Ib in which Z is an amide (--CONH--) there is a variety of methods for preparing the desired compounds (Scheme 14). One preferred method is to treat the ester 64 directly with an aluminum reagent derived from a suitable amine 65. This is accomplished by first treating the amine 65 with trimethylaluminum in a solvent such as methylene chloride or toluene and then adding the ester 64 and stirring at temperatures ranging from room temperature to 100.degree. C. This procedure affords the amide 66 directly. Another preferred method is to hydrolyze the ester 64 to the carboxylic acid 67 under basic conditions. The acid 67 can then be coupled to a suitable amine by many methods well known to those skilled in the art. One preferred method for this transformation is to treat 67 with oxalyl chloride or thionyl chloride to form the corresponding acid chloride. This intermediate can then be treated with amine 65 to afford the amide 66. Another method is to allow the acid 67 and the amine 65 to react in the presence of a suitable peptide coupling reagent, such as BOP-Cl, HBTU, DCC or any of a variety of such agents that are well known to those skilled in the art. ##STR22##
In Scheme 15 is shown how the ether, amine and ketone linking groups Z of Formula Ib compounds can be prepared from the carboxylic ester 64. To prepare the ether-linked compounds (Z=--CH.sub.2 O--), reduction of ester 64 to the corresponding primary alcohol is required. This transformation is possible by a variety of techniques. The preferred procedures involve the intermede carboxylic acid 67. The acid 67 can be reduced to the alcohol 68 directly with borane tetrahydrofuran complex or by a procedure involving sodium borohydride reduction of a mixed anhydride derived from carboxylic acid 67. Completion of the ether linked compounds of Formula Ib is readily accomplished from 68 by the Mitsonobu protocol with an appropriate phenol or hydroxyheterocycle 69 to give 70 (Formula Ib, A=aryl or heteroaryl). To prepare the amine-linked compounds of Formula Ib (Z=--CH.sub.2 NH--) alcohol 68 can be oxidized to aldehyde 71 by a number of procedures, two preferred methods of which are the Swern oxidation and oxidation with pyridinium chlorochromate (PCC). Reductive amination of aldehyde 71 with an appropriate amine 65 and sodium cyanoborohydride then affords the amine linked compounds 72. The aldehyde 71 also can be used to prepare the ketone-linked compounds of Formula Ib (Z=--COCH.sub.2 --). Treatment of 71 with an organometallic species of structure 73 affords the alcohol 74. Compound 73 (where M=magnesium or zinc) is best prepared from the corresponding halide by treatment with metallic magnesium or zinc. These reagents readily react with aldehydes to afford alcohols. Oxidation of alcohol 74 by any of a number of procedures, such as the Swern oxidation or PCC oxidation, affords the ketones 75. Alternatively, the ketones 75 can be prepared from the appropriate cinnamic or propionic acid derivatives 76. Treatment of 76 with the appropriate organomagnesium or organozinc reagent 76 affords either the unsaturated ketone 77 directly (when X in 76 is Cl, N(Me)OMe) or an intermediate alcohol (when X in 76 is H) which can subsequently be oxidized to 77 by procedures described above. Following the procedures described in Schemes 12 and 13, the unsaturated ketone 77 can be cyclized to the pyrrolidine or .DELTA..sup.3 -pyrroline and subsequently converted to 32. ##STR23##
In Scheme 16 is shown how compounds of Formula I containing the sulfonamide linking group (Z=--SO.sub.2 NH--) can be prepared. The styrene 78 can be treated with a variety of reagents, such as sulfuryl chloride or sulfur trioxide and phosphorous pentachloride, to afford the unsaturated sulfonyl chloride 79. Treatment with an appropriate amine 65 affords the sulfonamide 80 which can subsequently be converted into the sulfonamide-linked compounds 81 following the procedures described in Schemes 12 and 13. ##STR24##
In Scheme 17 is shown how compounds of Formula Ib containing the sulfone linking group (Z=--SO.sub.2 CH.sub.2 --) can be prepared. Treatment of readily available 82 with trimethylphosphite affords a phosphonate which, after treatment with a suitable base such as sodium hydride, reacts with the aldehyde 5 to afford the unsaturated sulfide 83. Oxidation to the corresponding sulfone 84 can be accomplished by a variety of reagents, such as KMnO.sub.4. Alternatively, the oxidation can be carried out prior to the condensation with aldehyde 5, in which case reaction of the anion of the sulfone phosphonate with 5 would give 84 directly. Following the procedures described in Schemes 12 and 13, the sulfone 84 can be converted to the sulfone-linked compounds 85. ##STR25##
All of the pyrrolidine and .DELTA..sup.3 -pyrroline derivatives described in Schemes 14-17 contain an aromatic cyano group which must be converted to its amidine derivative to prepare the final compounds described by Formula Ib. This can be accomplished using the reduction procedures described above in Scheme 6.
Where the group A-B in compounds of Formula Ib is a biphenyl residue, the chemistry described in Scheme 18 can be used. The biphenyl residue can be constructed using the palladium-catalyzed Suzuki coupling of an appropriate aryl halide 86 with an appropriate arylboronic acid 87 to give the biphenyl 88 (Miyaura et. al. Syn. Comm. 1981, 11, 513). This reaction in general is tolerant of a wide variety of substituents on both of the reacting partners. Thus, the reaction can be performed on a variety of compounds 86 where R' is a suitable precursor to the Z linking group found in compounds of Formula Ib. Alternatively, the coupling can be performed on a more fully elaborated aryl halide such as 89, where the pyrrolidine, .DELTA..sup.3 -pyrroline or isoxazolidine heterocycle is intact. Reaction with a suitable boronic acid 90 then would afford 91. The biphenyl compounds 88 and 91 can be carried on to the final products described by Formula Ib according to the procedures described in Schemes 14-17. ##STR26##

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, and pulmonary embolisms. The anticoagulant effect of compounds of the present invention is believed to be due to inhibition of factor Xa or thrombin.
The effectiveness of compounds of the present 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, Ohio) 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 0.10M sodium phosphate buffer, pH 7.5, containing 0.20M 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:
(v.sub.o -v.sub.s)/v.sub.s =I/(K.sub.i (1+S/K.sub.m))
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.
Using the methodology described above, a number of compounds of the present invention were found to exhibit a K.sub.i of .ltoreq.1 .mu.M, thereby confirming the utility of the compounds of the present invention as effective Xa inhibitors.
The antithrombotic effect of compounds of the present invention can be demonstrated in a rabbit arterio-venous (AV) shunt thrombosis model. In this model, rabbits weighing 2-3 kg anesthetized with a mixture of xylazine (10 mg/kg i.m.) and ketamine (50 mg/kg i.m.) are used. A saline-filled AV shunt device is connected between the femoral arterial and the femoral venous cannulae. The AV shunt device consists of a piece of 6-cm tygon tubing which contains a piece of silk thread. Blood will flow from the femoral artery via the AV-shunt into the femoral vein. The exposure of flowing blood to a silk thread will induce the formation of a significant thrombus. After forty minutes, the shunt is disconnected and the silk thread covered with thrombus is weighed. Test agents or vehicle will be given (i.v., i.p., s.c., or orally) prior to the opening of the AV shunt. 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 formula (I) may also be useful as inhibitors of serine proteases, notably human thrombin, plasma kallikrein and plasmin. Because of their inhibitory action, these compounds are indicated for use in the prevention or treatment of physiological reactions, blood coagulation and inflammation, catalyzed by the aforesaid class of enzymes. Specifically, the compounds have utility as drugs for the treatment of diseases arising from elevated thrombin activity such as myocardial infarction, and as reagents used as anticoagulants in the processing of blood to plasma for diagnostic and other commercial purposes.
Some compounds of the present invention were shown to be direct acting inhibitors of the serine protease thrombin by their ability to inhibit the cleavage of small molecule substrates by thrombin in a purified system. In vitro inhibition constants were determined by the method described by Kettner et al. in J. Biol. Chem. 265, 18289-18297 (1990), herein incorporated by reference. In these assays, thrombin-mediated hydrolysis of the chromogenic substrate S2238 (Helena Laboratories, Beaumont, Tex.) was monitored spectrophotometrically. Addition of an inhibitor to the assay mixture results in decreased absorbance and is indicative of thrombin inhibition. Human thrombin (Enzyme Research Laboratories, Inc., South Bend, Ind.) at a concentration of 0.2 nM in 0.10 M sodium phosphate buffer, pH 7.5, 0.20M NaCl, and 0.5% PEG 6000, was incubated with various substrate concentrations ranging from 0.20 to 0.02 mM. After 25 to 30 minutes of incubation, thrombin activity was assayed by monitoring the rate of increase in absorbance at 405 nm which arises owing to substrate hydrolysis. Inhibition constants were derived from reciprocal plots of the reaction velocity as a function of substrate concentration using the standard method of Lineweaver and Burk. Using the methodology described above, some compounds of this invention were evaluated and found to exhibit a K.sub.i of less than 5 .mu.m.
The compounds of the present 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" it 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" it 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, but are not limited to, 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 are preferred. 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 gastrointestinal tract in use. Still other suitable platelet inhibitory agents include IIb/IIIa antagonists, 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. A number of thrombin inhibitors are known to one of skill in the art and these inhibitors are contemplated to be used in combination with the present compounds. Such inhibitors include, but are not limited to, boroarginine derivatives, boropeptides, heparins, 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.
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 disclosure of which is hereby incorporated herein by reference herein. 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. For example, a compound of the present invention could be used as a reference in an assay to compare its known activity to a compound with an unknown activity. This would ensure the experimenter that the assay was being performed properly and provide a basis for comparison, especially if the test compound was a derivative of the reference compound. When developing new assays or protocols, compounds according to the present invention could be used to test their effectiveness.
The compounds of the present invention may also be used in diagnostic assays involving factor Xa. For example, the presence of factor Xa in an unknown sample could be determined by addition of chromogenic substrate S2222 to a series of solutions containing test sample and optionally one of the compounds of the present invention. If production of pNA is observed in the solutions containing test sample, but no compound of the present invention, then one would conclude factor Xa was present.
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 can be 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 may be 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 should be washed and dried.
Tablets
Tablets may be 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 may be prepared by stirring 1.5% by weight of active ingredient in 10% by volume propylene glycol and water. The solution should be made isotonic with sodium chloride and sterilized.
Suspension
An aqueous suspension can be 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 low-viscosity 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.
These as well as other ways of minimizing contact between the components of combination products of the present invention, whether administered in a single dosage form or administered in separate forms but at the same time by the same manner, will be readily apparent to those skilled in the art, once armed with the present disclosure.
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise that as specifically described herein.
