  • Osteo- and rheumatoid arthritis are destructive diseases of articular cartilage characterized by localized erosion of the cartilage surface. Findings have shown that articular cartilage from the femoral heads of patients with OA, for example, had a reduced incorporation of radiolabeled sulfate over controls, suggesting that there must be an enhanced rate of cartilage degradation in OA (Mankin et al. J. Bone Joint Surg. 52A, 1970, 424-434) .

  • MP metalloproteinases
  • This invention describes macrocyclic molecules that inhibit aggrecanase and other metalloproteinases. These novel molecules are provided as cartilage protecting therapeutics. The mhibiton of aggrecanase and other metalloproteinases by these novel molecules prevent the degradation of cartilage by these enzymes, thereby alleviating the pathological conditions of osteo- and rheumatoid arthritis.

Description

T ITLE
NOVEL MACROCYCLIC COMPOUNDS AS METALLOPROTEASE INHIBITORS
FIELD OF THE INVENTION
The present invention relates to macrocyclic molecules which inhibit metalloproteinases, including aggrecanase, and the production of tumor necrosis factor (TNF) , pharmaceutical preparations containing them and to their use as pharmaceutical agents. In particular the compounds are inhibitors of metalloproteinases involved in tissue degradation and inhibitors of the release of tumor necrosis factor.
BACKGROUND OF THE INVENTION
There is now a body of evidence that metalloproteinases (MP) are important m the uncontrolled breakdown of connective tissue, including proteoglycan and collagen, leading to resorption of the extracellular matrix. This is a feature of many pathological conditions, such as rheumatoid and osteoarthritis, corneal, epidermal or gastric ulceration; tumor metastasis or invasion; periodontal disease and bone disease. Normally these catabolic enzymes are tightly regulated at the level of their synthesis as well as at their level of extracellular activity through the action of specific inhibitors, such as alpha-2-macroglobulms and TIMP (tissue inhibitor of metalloprotemase) , which form inactive complexes with the MP's.
Osteo- and rheumatoid arthritis (OA and RA respectively) are destructive diseases of articular cartilage characterized by localized erosion of the cartilage surface. Findings have shown that articular cartilage from the femoral heads of patients with OA, for example, had a reduced incorporation of radiolabeled sulfate over controls, suggesting that there must be an enhanced rate of cartilage degradation in OA (Mankin et al. J. Bone Joint Surg. 52A, 1970, 424-434) . There are four classes of protein degradative enzymes in mammalian cells: serine, cysteine, aspartic and metalloproteinases. The available evidence supports that it is the metalloproteinases which are responsible for the degradation of the extracellular matrix of articullar cartillage in OA and RA. Increased activities of collagenases and stromelysin have been found in OA cartilage and the activity correlates with severity of the lesion (Mankin et al. Arthritis Rheum. 21, 1978, 761-766, Woessner et al. Arthritis Rheum. 26, 1983, 63-68 and Ibid. 27, 1984, 305-312). In addition, aggrecanase (a newly identified metalloprotemase enzymatic activity) has been identified that provides the specific cleavage product of proteoglycan, found in RA and OA patients (Lohmander L.S. et al. Arthritis Rheum. 36, 1993, 1214-22) .
Therefore metalloproteinases (MP) have been implicated as the key enzymes in the destruction of mammalian cartilage and bone. It can be expected that the pathogenesis of such diseases can be modified in a beneficial manner by the administration of MP inhibitors, and many compounds have been suggested for this purpose (see Wahl et al. Ann. Rep. Med. Chem. 25, 175-184, AP, San Diego, 1990) .
This invention describes macrocyclic molecules that inhibit aggrecanase and other metalloproteinases. These novel molecules are provided as cartilage protecting therapeutics. The mhibiton of aggrecanase and other metalloproteinases by these novel molecules prevent the degradation of cartilage by these enzymes, thereby alleviating the pathological conditions of osteo- and rheumatoid arthritis.
Tumor necrosis factor (TNF) is a cell associated cytokine that is processed from a 26kd precursor form to a 17kd active form. TNF has been shown to be a primary mediator in humans and in animals, of inflammation, fever, and acute phase responses, similar to those observed during acute infection and shock. Excess TNF has been shown to be lethal. There is now considerable evidence that blocking the effects of TNF with specific antibodies can be beneficial in a variety of circumsatnces including autoimmune diseases such as rheumatoid arthritis (Feldman et al, Lancet, 1994, 344, 1105) and non- msulm dependent diabetes melitus. (Lohmander L.S. et al. Arthritis Rheum. 36, 1993, 1214-22) and Crohn's disease (Macdonald T. et al. Clin. Exp. Immunol. 81, 1990, 301) . Compounds which inhibit the production of TNF are therefore of therapeutic importance for the treatment of inflammatory disorders. Recently it has been shown that a matrix metalloprotemase or family of metalloproteinases, hereafter known as TNF-convertases (TNF-C) , as well as other MP's are capable of cleaving TNF from its inactive to active form (Gearing et al Nature, 1994, 370, 555) . This invention describes macrocyclic molecules that inhibit this conversion and hence the secretion of active TNF-a from cells. These novel molecules provide a means of mechanism based therapeutic intervention for diseases including but not restricted to septic shock, haemodynamic shock, sepsis syndro , post ischaemic reperfusion injury, malaria, Crohn's disease, inflammatory bowel diseases, mycobacterial infection, meningitis, psoriasis, congestive heart failure, fibrotic diseases, cachexia, graft rejection, cancer, diseases involving angiogenesis, autoimmune diseases, skin inflammatory diseases, rheumatoid arthritis, multiple sclerosis, radiation damage, hyperoxic alveolar injury, HIV and non-insulin dependent diabetes melitus.
Since excessive TNF production has been noted in several disease conditions also charactarized by MMP-mediated tissue degradation, compounds which inhibit both MMPs and TNF production may also have a particular advantage in diseases where both mechansisms are involved.
There are several patents which disclose hydroxamate and carboxylate based MMP inhibitors.

The compounds of the current invention act as inhibitors of MMPs, in particular aggrecanase and TNF-C, thereby preventing cartilage loss and destruction and inflammatory disorders involving TNF. The hydroxamic and carboxylic acids and derivatives are cyclic, and thus non-peptide in nature, which offers a distinct advantage over existing inhibitors because they have superior pharmacokmetic parameters. A selection of these molecules are water soluble and are orally bioavailable.

In the present invention it has been discovered that the compounds above are useful as inhibitors of metalloproteinases, including aggrecanase and TNF-C, and are useful for the treatment of rheumatoid arthritis, osteoarthritis and related inflammatory disorders, as described previously. These compounds inhibit the production of TNF in animal models and are useful for the treatment of diseases mediated by TNF.
The present invention also provides methods for the treatment of osteo- and rheumatoid arthritis and related disorders as described previously, by administering to a host a pharmaceutically or therapeutically effective or acceptable amount of a compound of the present invention as described above. By therapeutically effective amount, it is meant an amount of a compound of the present invention effective to inhibit the target enzyme or to treat the symptoms of osteo- or rheumatoid arthritis or related disorder, in a host.
The compounds of the present invention can also be administered in combination with one or more additional therapeutic agents. Administration of the compounds of the present 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.
By "therapeutically effective amount" it is meant an amount of a compound of the present invention that when administered alone or in combination with an additional therapeutic agent to a cell or mammal is effective to inhibit the target enzyme so as to prevent or ameliorate the inflamatory disease condition or the progression of the disease.
By "administered in combination" or "combination therapy" it is meant that a compound of the present invention 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. By "stable compound" or "stable structure" is meant herein 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.
The compounds herein described may have asymmetric centers. Unless otherwise indicated, all chiral, diastereomeric and racemic forms are included in the present invention.

It will be appreciated that compounds of the present invention may contain asymmetrically substituted carbon atoms, and 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. All chiral, diastereomeric, racemic forms and all geometric lsomeric forms of a structure are intended, unless the specific stereochemistry or isomer form is specifically indicated.
When a bond to a substituent is shown to cross the 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 the present invention then such substituent may be bonded via any atom in such substituent. For example, when the substituent is piperazmyl, pipeπdmyl, or tetrazolyl, unless specified otherwise, said piperazmyl, piperidinyl, tetrazolyl group may be bonded to the rest of the compound via any atom in such piperazinyl, piperidinyl, tetrazolyl group.
Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds. By stable compound or stable structure it is meant herein 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.

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.
The novel compounds of this invention may be prepared using the reactions and techniques described in this section. The reactions are performed in solvents appropriate to the reagents and materials employed and are suitable for the transformations being effected. Also, in the description of the synthetic methods described below, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and workup procedures, are chosen to be the conditions standard for that reaction, which should be readily recognized by one skilled in the art. It is understood by one skilled in the art of organic synthesis that the functionality present on various portions of the molecule must be compatible with the reagents and reactions proposed. Such restrictions to the substituents which are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternate methods must then be used.
The compounds of the present invention may be prepared by the methods outlined in the Schemes below. A diprotected 2,3- diammopropionic acid, 2, 4-dιammobutyrιc acid, ornithine or lysme (compound 1, Scheme 1) is converted to its corresponding amide 2 using a coupling agent such as BOP. Coupling of 1 with a diaminobenzene followed by reaction m acetic acid at 60_ C produces a benzimidazole analog 3. 1 can also be converted to an aldehyde 4 which is reacted with ammonia and glyoxal trimer to give an imidazole analog 5. Deprotection of the Na-Boc group of 2, 3 and 5 using an acid such as 4 N HC1 in dioxane gave compound 6. Removal of the side chain protecting group of 2, 3 and 5 using hydrogenation afforded compound 7.

The synthesis of the 2, 3-disubstituted succinic acid portion is described in Scheme 2 below. The acid chloride 8 (X = Cl) is converted to its oxazolidinone derivative 10 using n-butyl lithium. An asymmetric alkylation (JACS, 1982, 104, 1737) followed by removal of the chiral auxiliary converts 10 to the acid 11. A second alkylation gives compound 12. This can be epimerized with LDA and Et2AlCl to give compound 13. The benzyl ester 14 is then made by standard methods. When 14 contains R: as an olefin, it can be converted to the alcohol 15 via hydroboration .

The t-butyl ester is converted to the acid 114 using TFA. This material is converted to the O-benzyl hydroxamate 115 via a standard coupling reaction. The methyl ester can be hydrolyzed to the acid and then converted to the desired R2 group to give 117. This material is hydrogenated to give the final desired hydroxamate 118.

A compound is considered to be active if it has an IC50 or K__ value of less than about 1 mM for the inhibition of MMP-3.
Aggrecanase Enzymatic Assay
A novel enzymatic assay was developed to detect potential inhibitors of aggrecanase. The assay uses active aggrecanase accumulated in media from stimulated bovine nasal cartilage (BNC) or related cartilage sources and purified cartilage aggrecan monomer or a fragment thereof as a substrate.
The substrate concentration, amount of aggrecanase time of mcubation and amount of product loaded for Western analysis were optimized for use of this assay in screening putative aggrecanase inhibitors. Aggrecanase is generated by stimulation of cartilage slices with mterleukm-1 (IL-1) , tumor necrosis factor alpha (TNF_) or other stimuli. Matrix metalloproteinases (MMPs) are secreted from cartilage in an inactive, zymogen form following stimulation, although active enzymes are present within the matrix. We have shown that following depletion of the extracellular aggrecan matrix, active MMPs are released into the culture media. (Tortorella, M.D. et. al. Trans. Ortho. Res. Soc. 20, 341, 1995) . Therefore, in order to accumulate BNC aggrecanase m culture media, cartilage is first αepleted of endogenous aggrecan by stimulation with 500 ng/ml human recombinant IL-β for 6 days with media changes every 2 days. Cartilage is then stimulated for an additional 8 days without media change to allow accumulation of soluble, active aggrecanase in the culture media. In order to decrease the amounts of other matrix metalloproteinases released into the media during aggrecanase accumulation, agents which inhibit MMP- 1, -2, -3, and -9 biosynthesis are included during stimulation. This BNC conditioned media, containing aggrecanase activity is then used as the source of aggrecanase for the assay. Aggrecanase enzymatic activity is detected by monitoring production of aggrecan fragments produced exclusively by cleavage at the Glu373-Ala374 bond within the aggrecan core protein by Western analysis using the monoclonal antibody, BC-3 (Hughes, CE, et al., Biochem J 306:799-804, 1995). This antibody recognizes aggrecan fragments with the N-termmus, 374ARGSVIL.. , generated upon cleavage by aggrecanase. The BC-3 antibody recognizes this neoepitope only when it is at the N- termmus and not when it is present internally within aggrecan fragments or withm the aggrecan protein core. Other proteases produced by cartilage in response to IL-1 do not cleave aggrecan at the Glu373-Ala374 aggrecanase site; therefore, only products produced upon cleavage by aggrecanase are detected. Kinetic studies using this assay yield a Km of 1.5 +/- 0.35 uM for aggrecanase .
To evaluate inhibition of aggrecanase, compounds are prepared as 10 mM stocks in DMSO, water or other solvents and diluted to appropriate concentrations in water. Drug (50 ul) is added to 50 ul of aggrecanase-containing media and 50 ul of 2 mg/ml aggrecan substrate and brought to a final volume of 200 ul in 0.2 M Tris, pH 7.6, containing 0.4 M NaCl and 40 mM CaC12. The assay is run for 4 hr at 37oC, quenched with 20 mM EDTA and analyzed for aggrecanase-generated products. A sample containing enzyme and substrate without drug is included as a positive control and enzyme incubated in the absence of substrate serves as a measure of background.
Removal of the glycosaminoglycan side chains from aggrecan is necessary for the BC-3 antibody to recognize the ARGSVIL epitope on tne core protein. Therefore, for analysis of aggrecan fragments generated by cleavage at the Glu373-Ala374 site, proteoglycans and proteoglycan fragments are enzymatically deglycosylated with chondroitmase ABC (0.1 units/10 ug GAG) for 2 hr at 37oC and then with keratanase (0.1 units/10 ug GAG) and keratanase II (0.002 units/10 ug GAG) for 2 hr at 37oC n buffer containing 50 mM sodium acetate, 0.1 M Tπs/HCl, pH 6.5. After digestion, aggrecan m the samples is precipitated with 5 volumes of acetone and resuspended in 30 ul of Tris glycine SDS sample buffer (Novex) containing 2.5% beta mercaptoethanol . Samples are loaded and then separated by SDS-PAGE under reducing conditions with 4-12% gradient gels, transferred to nitrocellulose and immunolocated with 1:500 dilution of antibody BC3. Subsequently, membranes are incubated with a 1:5000 dilution of goat anti-mouse IgG alkaline phosphatase second antibody and aggrecan catabolites visualized by incubation with appropriate substrate for 10-30 minutes to achieve optimal color development. Blots are quantitated by scanning densitometry and inhibition of aggrecanase determined by comparing the amount of product produced in the presence versus absence of compound.
Bisacetylated Substance P / MMP-3 fluorescent Assay
A high capacity enzymatic assay was developed to detect potential inhibitors of MMP-3. The assay uses a derivative of a peptide substrate, substance P (Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe- Gly-Leu-Met ) , which is cleaved by MMP-3 exclusively at the glutamme-phenylalanine bond. In order to adapt this assay for high throughput screening, we have developed a fluorimetnc method of product detection. The production of the hydrolysis product, substance P 7-11, is measured by reaction with fluorescamme, a fluorogenic compound which reacts with the primary amine of this fragment. The substance P substrate is bisacetylated to block the primary amines of the intact substrate. Thus, the resulting fluorescence represents generation of product (7-11 peptide) formed upon cleavage by MMP-3, and is quantitated using a standard curve prepared with known concentrations of 7-11 peptide. Kinetic studies using the bisacetylated substrate yield the following parameters for MMP- 3: Km =769 +/- 52 uM; Vmax = 0.090 +/- 0.003 nmoles 7-11 peptide/min.
To evaluate inhibition of MMP-3, compounds were prepared at a concentration of 10 mM in 100% methanol, and then further diluted to a 20X molar stock. Five microliters of each drug stock was added to the assay in the presence of 20 nM truncated MMP-3 in 67.5 mM tricine (pH 7.5), 10 mM CaCl2, 40 mM NaCl, and
0.005% Brij 35 in a final volume of 100 microliters. Bisacetylated substance P (1000 rruM) was added, and the assay was run for 1 hour at 25 C. The reaction was quenched with EDTA (20 mM) and product was detected fluorometrically following addition of fluorescamine (0.075 mg/ml). Fluorescence of each sample was converted to an amount of product formed using a substance P 7- 11 standard curve. Under these conditions, the assay is linear with respect to MMP-3 amount up to 10 pmoles. Inhibition of MMP-3 was determined by comparing the amount of product generated in the presence and absence of compound.
Selected compounds of the present invention were tested and shown to have activity in the above assay.
Ex vivo assay for bioavailability of MMP-3 inhibitors
Blood was collected by cardiac puncture from rats at different times after dosing I.V., I. P., or P.O. with compound in order to determine the levels of inhibitor present. Plasma was extracted with 10% TCA in 95% methanol, and placed on ice for 10 minutes. The plasma was then centrifuged for 15 minutes at 14,000 rpm in an Eppendorf microcentrifuge . The supernatant was removed, recentrifuged, and the resulting supernatant was diluted 1:10 in 50 mM tricine, pH 8.5. The pH of the sample was adjusted to 7.5, and then assayed in the MMP-3 substance P fluorescent enzymatic assay. Plasma from naive rats was extracted by the same method and used as a negative control. This plasma was also used to prepare a spiked plasma curve of the compound of interest. Known concentrations of the compound were added to control plasma, the plasma was extracted by the same method, and then assayed in the MMP-3 enzymatic assay. A standard curve was prepared that related percent inhbition in the MMP-3 assay to the concentration of drug added in the spiked samples. Based on the percent inhibition in the presence of plasma from dosed rats, the concentration of compound was determined using the standard curve.
Acute Cartilage Degradation Rat Model
A novel m vivo model of acute cartilage degradation in rats has been characterized as a method to determine the proteoglycan content m the synovial fluid after the induction of cartilage degradation. Experimental groups exhibit increased levels of proteoglycan content m their synovial fluid versus control rats. The criteria to demonstrate a compound's activity in this model, is the ability to inhibit the demonstration of cartilage degradation, as measured by increased proteoglycan content m the synovial fluid of rats after compound administration. Indomethacm, a non-steroidal anti-mflammatory drug is inactive in this model. Indomethacm administration does not inhibit the demonstration of cartilage degradation in experimental animals. In contrast, administration of a compound of this invention significantly inhibited the demonstration of cartilage degradation in this model.
TNF Human Whole Blood Assay
Blood is drawn from normal donors into tubes containing 143 USP units of heparm/lOml. 225ul of blood is plated directly into sterile polypropylene tubes. Compounds are diluted in DMSO/serum free media and added to the blood samples so the final concentration of compounds are 50, 10, 5, 1, .5, .1, and .OluM. The final concentration of DMSO does not exceed .5%. Compounds are premcubated for 15 minutes before the addition of lOOng/ml LPS. Plates are incubated for 5 hours in an atmosphere of 5% C02 in air. At the end of 5 hours, 750ul of serum free media is added to each tube and the samples are spun at 1200RPM for 10 minutes. The supernatant is collected off the top and assayed for TNF-alpha production by a standard sandwich ELISA. The ability of compounds to inhibit TNF-alpha production by 50% compared to DMSO treated cultures is given by the IC50 value. TNF Induction In Mice
Test compounds are administered to mice either I. P. or P.O. at time zero. Immediately following compound administration, mice receive an I. P. injection of 20 mg of D-galactosamme plus 10 μg of lipopolysaccharide . One hour later, animals are anesthetized and bled by cardiac puncture. Blood plasma is evaluated for TNF levels by an ELISA specific for mouse TNF. Administration of representative compounds of the present invention to mice results in a dose-dependent suppression of plasma TNF levels at one hour in the above assay.

For a normal male adult human of approximately 70 kg of body weight, this translates into a dosage of 70 to 1400 mg/day. Intravenously, the most preferred doses will range from about 1 to about 10 mg/kg/mmute during a constant rate infusion. Advantageously, compounds of the present invention may be administered m a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily.
The compounds for the present invention can be administered in mtranasal form via topical use of suitable mtranasal vehicles, or via transdermal routes, using those forms of transdermal skin patches wall known to those of ordinary skill n that art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than mtermittant throughout the dosage regimen.
In the methods of the present invention, the compounds herein described in detail can form the active ingredient, and are typically administered m admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as carrier materials) 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 algmate, 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 unilamallar vesicles, and multilamellar vesicles. Liposomes can be formed from a variety of phosphol pids, such as cholesterol, stearylamine, or phosphatidylcholmes .
Compounds of the present invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvmylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol, polyhydroxyethylaspartamidephenol, or polyethyleneoxide- polylysme substituted with palmitoyl residues. Furthermore, the compounds of the present invention may be coupled to a class of biodegradable polymers useful 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 crosslmked 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.
The active ingredient can be administered orally in solid dosage forms, such as capsules, tablets, and powders, or in liquid dosage forms, such as elixirs, syrups, and suspensions. It can also be administered parenterally, in sterile liquid dosage forms .
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. Antioxidizmg 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 .

The compounds of the present invention may be administered in combination with a second therapeutic agent, especially non- steroidal anti-mflammatory drugs (NSAID's). The compound of the present invention and such second therapeutic agent can be administered separately or as a physical combination in a single dosage unit, in any dosage form and by various routes of administration, as described above.
The compound of the present invention may be formulated together with the second therapeutic agent m a single dosage unit (that is, combined together in one capsule, tablet, powder, or liquid, etc.) . When the compound of the present invention and the second therapeutic agent are not formulated together in a single dosage unit, the compound of the present invention and the second therapeutic agent may be administered essentially at the same time, or in any order; for example the compound of the present invention may be administered first, followed by administration of the second agent. When not administered at the same time, preferably the administration of the compound of the present invention and the second therapeutic agent occurs less than about one hour apart, more preferably less than about 5 to 30 minutes apart.
Preferably the route of administration of the compound of the present invention is oral. Although it is preferable that the compound of the present invention and the second therapeutic agent are both administered by the same route (that is, for example, both orally) , if desired, they may each be administered by different routes and in different dosage forms (that is, for example, one component of the combination product may be administered orally, and another component may be administered intravenously) .
The dosage of the compound of the present invention when administered alone or in combination with a second therapeutic agent may vary depending upon various factors such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration, the age, health and weight of the recipient, the nature and extent of the symptoms, the kind of concurrent treatment, the frequency of treatment, and the effect desired, as described above.
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 the present invention and a second therapeutic agent are combined in a single dosage unit they are formulated such that although tne active ingredients are comoined in a single dosage unit, the physical contact between the active ingredients is minimized (that is, reduced). For example, one active ingredient may oe 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 sustained-release 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.
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.
