FIELD OF THE INVENTION
The present invention relates to substituted compounds useful as 5-lipoxygenase-activating protein (FLAP) modulators, pharmaceutical compositions of such compounds, methods of preparation and use thereof. More particularly, FLAP modulators are useful for preventing, treating or ameliorating FLAP-mediated diseases and/or disorders, including those inflammation diseases and/or disorders associated with dermatological and respiratory disorders, allergic disorders, autoimmunity, cancer, cardiovascular and metabolic disorders.
BACKGROUND OF THE INVENTION
FLAP is a key initiator of the leukotriene synthesis pathway that binds and then transfers arachidonic acid to 5-lipoxygenase (M. Abramovitz et al., “5-lipoxygenase-activating protein stimulates the utilization of arachidonic acid by 5-lipoxygenase,” Eur. J. Biochem., 1993, 215, 105-11). FLAP has been demonstrated to interact with LTC4 synthase, and could putatively modulate the production of LTC4 (T. Strid et al., “Distinct parts of leukotriene C(4) synthase interact with 5-lipoxygenase and 5-lipoxygenase activating protein,” Biochem. Biophys. Res. Comm., 2009, 381(4), 518-22). Modulation (including without limitation inhibition) or genetic deletion of FLAP blocks leukotriene production, specifically LTB4, the cysteinyl leukotrienes (LTC4, LTD4 and LTE4) as well as 5-oxo-ETE (J. Z. Haeggström et al., “Lipoxygenase and leukotriene pathways: biochemistry, biology, and roles in disease,” Chem Rev., 2011, 111(10), 5866-98).
Leukotrienes are immune-modulating lipids formed from arachidonic acid (reviewed in B. Samuelsson, “Leukotrienes: mediators of immediate hypersensitivity reactions and inflammation,” Science, 1983, 220, 568-75). They are synthesized primarily by eosinophils, neutrophils, mast cells, basophils, dendritic cells, macrophages and monocytes. Leukotrienes mediate multiple biological effects including, by way of example only, smooth muscle contraction, leukocyte recruitment and activation, cytokine secretion, fibrosis, mucous secretion, and vascular function (J. Z. Haeggström, at 5866-98).
FLAP-deficient mice are healthy and reproduce normally. They do not produce leukotrienes and have decreased susceptibility in mouse models of arthritis (R. J. Griffiths et al., “Collagen-induced arthritis is reduced in 5-lipoxygenase-activating protein-deficient mice,” J. Exp. Med., 1997, 185, 1123-29). In humans, FLAP itself has been linked by genetic studies to respiratory disorders and cardiovascular disease, including myocardial infarction, atherosclerosis, cerebral infarctions, coronary artery disease and stroke (A. Helgadottir et al., “The gene encoding 5-lipoxygenase activating protein confers risk of myocardial infarction, atherosclerosis and stroke,” Nat. Genet., 2004, 36, 233-39; A. S. Tulah et al., “The role of ALOX5AP, LTA4H and LTB4R polymorphisms in determining baseline lung function and COPD susceptibility in UK smokers,” BMC Med. Genet., 2011, 29(12), 173; R. Ji et al., “Genetic variants in the promoter region of the ALOX5AP gene and susceptibility of ischemic stroke,” Cerebrovasc. Dis., 2011, 32(3), 261-68; J. W. Holloway et al., “The role of LTA4H and ALOX5AP polymorphism in asthma and allergy susceptibility,” Allergy, 2008, 63(8), 1046-53; J. Nair et al., “Expression analysis of leukotriene-inflammatory gene interaction network in patients with coronary artery disease,” J Atheroscler. Thromb., 2013; L. F. Chi et al., “Interaction between ALOX5AP and CYP3A5 gene variants significantly increases the risk for cerebral infarctions in Chinese,” Neuroreport., 2013). In addition, studies using animal models support a causative role for leukotrienes in aortic aneurisms, pulmonary arterial hypertension, myocardial infarction, atherosclerosis, and stroke (reviewed in J. Z. Haeggström, at 5866-98).
Leukotrienes also play a role in autoimmune disorders such as rheumatoid arthritis, inflammatory bowel disease, nephritis, spondyloarthritis, polymyositis, dermatomyositis, gouty effusions, systemic lupus erythematosus, systemic sclerosis, Alzheimer's disease and multiple sclerosis (S. Chwieśko-Minarowska et al., “The role of leukotrienes in the pathogenesis of systemic sclerosis,” Folia Histochem. Cytobiol., 2012, 50(2), 180-85; M. Rosnowska et al., “Leukotrienes C4 and B4 in cerebrospinal fluid of patients with multiple sclerosis,” Pol. Merkuriusz Lek., 1997, 2, 254-55; and reviewed in J. Z. Haeggström, at 5866-98; I. Loell et al., “Activated LTB4 pathway in muscle tissue of patients with polymyositis or dermatomyositis,” Ann. Rheum. Dis., 2013, 72(2), 293-99; J. Chu et al., “Involvement of 5-lipoxygenase activating protein in the amyloidotic phenotype of an Alzheimer's disease mouse model,” J. Neuroinflammation, 2012, 9, 127). Leukotrienes have also been implicated in several aspects of carcinogenesis including tumor cell proliferation, differentiation, apoptosis, tumor-associated angiogenesis, as well as the migration and invasion of carcinoma cells (D. Wang and R. N. Dubois, “Eicosanoids and cancer,” Nat. Rev. Cancer, 2010, 10(3), 181-93).
Leukotrienes play a key role in allergic disorders such as allergic rhinitis, allergic dermatitis and asthma, as well as respiratory disorders such as exacerbations, non-allergic asthma, aspirin exacerbated respiratory disease, fibrotic lung diseases, acute respiratory distress syndrome and chronic obstructive pulmonary disease (reviewed in J. Z. Haeggström at 5866-98). Approved antagonists of the LTC4 receptor and leukotriene synthesis modulators such as zileuton have shown clinical efficacy in a variety of respiratory disorders (reviewed in M. E. Krawiec and S. E. Wenzel, “Leukotriene modulators and non-steroidal therapies in the treatment of asthma,” Expert. Opin. Pharmacotherapy, 2001, 2(1), 47-65).
All the above evidence supports a key role of leukotrienes in a variety of human diseases and/or disorders, and FLAP modulation would be effective for the prevention, treatment, or amelioration of these immune-mediated inflammatory diseases and/or disorders. Furthermore, there still remains a need for FLAP modulator compounds that have pharmacokinetic and pharmacodynamic properties suitable for use as human pharmaceuticals.

For prophylactic purposes (i.e., inhibiting the progression of a disorder), the term “therapeutically effective amount” refers to that amount of each active compound or pharmaceutical agent, alone or in combination, that treats or inhibits in a subject the progression of a disorder as being sought by a researcher, veterinarian, medical doctor or other clinician. Thus, the present invention provides combinations of two or more drugs wherein, for example, (a) each drug is administered in an independently therapeutically or prophylactically effective amount; (b) at least one drug in the combination is administered in an amount that is sub-therapeutic or sub-prophylactic if administered alone, but is therapeutic or prophylactic when administered in combination with the second or additional drugs according to the invention; or (c) both (or more) drugs are administered in an amount that is sub-therapeutic or sub-prophylactic if administered alone, but are therapeutic or prophylactic when administered together. The effective amount of said compound is from about 0.001 mg/kg/day to about 300 mg/kg/day.
Advantageously, the effective amount of a combination product for treating an FLAP-mediated disease and/or disorder, or associated symptoms or complications thereof, may be a reduced amount of either or both, the compound or therapeutic agent, compared to the effective amount of the compound or therapeutic agent otherwise recommended for treating the disease and/or disorder, or associated symptoms or complications thereof. Therefore, it is contemplated that the compound is administered to the subject before, during or after the time the agent is administered.
The term “pharmaceutically acceptable salt” refers to non-toxic pharmaceutically acceptable salts (Ref. Int'l J. Pharm., 1986, 33: 201-217; J. Pharm. Sci., 1997 (January), 66(1): 1). Other salts well known to those in the art may, however, be useful in the preparation of compounds according to this invention or of their pharmaceutically acceptable salts. Representative organic or inorganic acids include, but are not limited to, hydrochloric, hydrobromic, hydriodic, perchloric, sulfuric, nitric, phosphoric, acetic, propionic, glycolic, lactic, succinic, maleic, fumaric, malic, tartaric, citric, benzoic, mandelic, methanesulfonic, hydroxyethanesulfonic, benzenesulfonic, oxalic, pamoic, 2-naphthalenesulfonic, p-toluenesulfonic, cyclohexanesulfamic, salicylic, saccharinic or trifluoroacetic acid. Representative organic or inorganic bases include, but are not limited to, basic or cationic salts such as benzathine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine, procaine, aluminum, calcium, lithium, magnesium, potassium, sodium and zinc.
The compounds of the invention may be present in the form of pharmaceutically acceptable salts. For use in medicines, the “pharmaceutically acceptable salts” of the compounds of this invention refer to non-toxic acidic/anionic or basic/cationic salt forms.
Suitable salt forms include acid addition salts which may, for example, be formed by mixing a solution of the compound according to the invention with a solution of an acid such as acetic acid, adipic acid, benzoic acid, carbonic acid, citric acid, fumaric acid, glycolic acid, hydrochloric acid, maleic acid, malonic acid, phosphoric acid, saccharinic acid, succinic acid, sulphuric acid, tartaric acid, trifluoroacetic acid and the like.
Furthermore when the compounds of the present invention carry an acidic moiety, suitable salts thereof may include alkali metal salts, e.g. sodium or potassium salts; alkaline earth metal salts, e.g. calcium or magnesium salts; and salts formed with suitable organic ligands, e.g. quaternary ammonium salts.
During any of the processes for preparation of the compounds of the present invention, it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by means of conventional protecting groups, such as those described in Protective Groups in Organic Chemistry, ed. J. F. W. McOmie, Plenum Press, 1973; and T. W. Greene & P. G. M. Wuts, Protective Groups in Organic Synthesis, 3rd Edition, John Wiley & Sons, 1999. The protecting groups may be removed at a convenient subsequent stage using methods known in the art. The scope of the present invention encompasses all such protected compound forms and mixtures thereof.
The invention includes compounds of various isomers and mixtures thereof. The term “isomer” refers to compounds that have the same composition and molecular weight but differ in physical and/or chemical properties. Such substances have the same number and kind of atoms but differ in structure. The structural difference may be in constitution (geometric isomers) or in an ability to rotate the plane of polarized light (optical isomers).
The term “stereoisomer” refers to isomers that have the same molecular formula and the same sequence of covalently bonded atoms but a different spatial orientation.
The term “optical isomer” means isomers of identical constitution that differ only in the spatial arrangement of their groups. Optical isomers rotate the plane of polarized light in different directions. The term “optical activity” means the degree to which an optical isomer rotates the plane of polarized light.
The term “racemate” or “racemic” means an equimolar mixture of two enantiomeric species, wherein each of the isolated species rotates the plane of polarized light in the opposite direction such that the mixture is devoid of optical activity.
The term “enantiomer” means an isomer having a nonsuperimposable mirror image. The term “diastereomer” means stereoisomers that are not enantiomers.
The term “chiral” means a molecule that, in a given configuration, cannot be superimposed on its mirror image. This is in contrast to achiral molecules that can be superimposed on their mirror images.
The two distinct mirror image versions of the chiral molecule are also known as levo (left-handed), abbreviated L, or dextro (right-handed), abbreviated D, depending on which way they rotate polarized light. The symbols “R” and “S” represent the configuration of groups around a stereogenic carbon atom(s).
The symbols “R” and “S” are used in compound names and/or compound structures to describe a pure enantiomer, where the absolute stereochemistry of groups around a stereogenic carbon atom(s) is known.
The symbols “R*” and “S*” are used in compound names and/or compound structures to describe a pure enantiomer, where the relative stereochemistry of groups around a stereogenic carbon atom(s) is known, but where the absolute stereochemistry is unknown.
The term “geometric isomer” means isomers that differ in the orientation of substituent atoms in relationship to a carbon-carbon double bond, to a cycloalkyl ring, or to a bridged bicyclic system. Substituent atoms (other than hydrogen) on each side of a carbon-carbon double bond may be in an E or Z configuration according to the Cahn-Ingold-Prelog priority rules. In the “E” configuration, the substituents having the highest priorities are on opposite sides in relationship to the carbon-carbon double bond. In the “Z” configuration, the substituents having the highest priorities are oriented on the same side in relationship to the carbon-carbon double bond.
Substituent atoms (other than hydrogen) attached to a ring system may be in a “cis” or “trans” configuration. In the “cis” configuration, the substituents are on the same side in relationship to the plane of the ring; in the “trans” configuration, the substituents are on opposite sides in relationship to the plane of the ring. Compounds having a mixture of “cis” and “trans” species are designated “cis/trans”.
The compounds of the invention may be prepared as individual isomers by either isomer-specific synthesis or resolved from an isomeric mixture. Conventional resolution techniques include combining the free base (or free acid) of each isomer of an isomeric pair using an optically active acid (or base) to form an optically active salt (followed by fractional crystallization and regeneration of the free base), forming an ester or amide of each of the isomers of an isomeric pair by reaction with an appropriate chiral auxiliary (followed by fractional crystallization or chromatographic separation and removal of the chiral auxiliary), or separating an isomeric mixture of either an intermediate or a final product using various well known chromatographic methods.
Furthermore, compounds of the present invention may have one or more polymorph or amorphous crystalline forms and, as such, are intended to be included in the scope of the invention. In addition, some of the compounds may form solvates with water (i.e., hydrates) or common organic solvents (e.g., organic esters such as ethanolate and the like) and, as such, are also intended to be encompassed within the scope of this invention.
B) SYNTHESIS
The invention provides methods of making the disclosed compounds according to traditional organic synthetic methods as well as matrix or combinatorial synthetic methods. Schemes A-D described suggested synthetic routes. Using the schemes, the guidelines below, and the examples, a person of skill in the a may develop analogous or similar methods for a given compound that is within the invention. These methods are representative of the synthetic schemes, but are not to be construed as limiting the scope of the invention.
Where the compounds according to this invention have at least one chiral center, they may accordingly exist as enantiomers. Where the compounds possess two or more chiral centers, they may additionally exist as diastereomers. Where the processes for the preparation of the compounds according to the invention give rise to mixtures of stereoisomers, these isomers may be separated by conventional techniques such as preparative chromatography. The compounds may be prepared in racemic form or as individual enantiomers or diasteromers by either stereospecific synthesis or by resolution. The compounds may, for example, be resolved into their component enantiomers or diastereomers by standard techniques, such as the formation of stereoisomeric pairs by salt formation with an optically active base, followed by fractional crystallization and regeneration of the free acid. The compounds may also be resolved by formation of stereoisomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using a chiral HPLC column. It is to be understood that all stereoisomers, racemic mixtures, diastereomers, geometric isomers, and enantiomers thereof are encompassed within the scope of the present invention.
Representative compounds of the present invention can be synthesized in accordance with the general synthetic schemes described below and are illustrated more particularly in the specific synthetic examples that follow. The general schemes are offered by way of illustration; the invention should not be construed as being limited by the chemical reactions and conditions expressed. The methods for preparing the various starting materials used in the schemes and examples are well within the skill of persons versed in the art. No attempt has been made to optimize the yields obtained in any of the example reactions. One skilled in the art would know how to increase such yields through routine variations in reaction times, temperatures, solvents and/or reagents.

The compounds of Formula (I), wherein ring A, R1, R5 and R6 are defined as in Formula (I), may be synthesized as outlined by the general synthetic route illustrated in Scheme A.




Referring to Scheme A, compounds of Formulae (I) are prepared from cyclization of diamines (V) with anhydrides, di-acids, or aldehyde containing acids where R1 is an aryl or heteroaryl substituent and R5 may contain substituents such as alkyl or cycloalkyl carboxylic acids. Ring A may represent or contain various substituents such as alkyls, cycloalkyls, halogens, amines, ethers, and aromatic or heteroaromatic rings. Various substituted anhydrides and diacids used in the preparation of compounds of Formulae (I) were obtained from commercial sources or were prepared using known methods. R6 may be hydrogen or one of various alkyl substituents. Diamines of formula (V) are obtained via alkylation of 4-fluoro-3-nitrophenol (II) with aryl or heteroaryl methylhalides. Preferably, 4-fluoro-3-nitrophenol (II) is treated with the desired halide in the presence of a base, such as K2CO3, Cs2CO3, or NaOH, with or without the presence of potassium iodide in a suitable polar solvent, such as CH3CN, dimethyl formamide (DMF), dimethyl acetamide (DMA), tetrahydrofuran (THF), or a mixture thereof, at a temperature ranging from about 50° C. to about 180° C. using conventional heating or microwave irradiation. Nitroethers (III) are converted to compounds of Formulae (IV) via nucleophilic aromatic substitution (SNAr) with aryl or heteroaryl-substituted methylene amines in the presence of a suitable base, such as DIPEA, Et3N, or a mixture thereof, in a solvent, such as CH3CN, DMF, DMA, N-methyl-2-pyrrolidone (NMP) or a mixture thereof, at a temperature ranging from about 50° C. to about 150° C. Diamines (V) are obtained by reduction of the nitro group using generally known methods, such as hydrogenation over a Pd or Pt catalyst using H2, in solvents, such as THF, MeOH and EtOH, with or without the presence of DIPEA, or Et3N. Alternatively, the nitro group can be reduced through the use of a heterogeneous stoichiometric reductant, such as Zn metal powder, in the presence of an acid, such as NH4Cl or HOAc, in a solvent, such as MeOH, EtOH, acetone, or THF, at a temperature ranging from 0° C. to the reflux temperature of the solvent. Additionally, reduction can occur in the presence of a homogeneous stoichiometric reductant, such as SnCl2.2H2O, in solvents, such as EtOH, MeOH, and EtOAc, at temperatures ranging from 0° C. to the reflux temperature of the solvent. Formation of (I) can be achieved in a two-step process by first reacting diamine (V) with appropriate anhydrides in the presence of a base, such as DIPEA, in a solvent, such as CH3CN, at a temperature ranging from about 50° C. to about 90° C. The product thus obtained is converted to (I) by subjecting it to further heating from 0° C. to the reflux temperature of the solvent, either conventionally or in a microwave reactor, in the presence of an acid, such as HCl, HOAc, or MsOH. Alternatively, formation of (I) can be achieved by heating diamine (V) and an appropriate organic diacid in the presence of a strong acid catalyst or Lewis acidic dehydrating agent, such as HCl or SnCl4 respectively, at a temperature ranging from about 50° C. to about 90° C. In some instances, such as to ease purification, it is desirable to convert (I) to the corresponding alkyl ester by treating (I) with a strong acid, such as HCl, in the presence of an alcoholic solvent, such as EtOH or MeOH, at temperatures ranging from RT to 100° C. Methylesters of (I) can also be obtained using TMSCHN2 in a mixture of toluene and MeOH. Benzimidazole (I) is then obtained by subsequent hydrolysis using known acidic or basic conditions. Preferably, hydrolysis is conducted using a base, such as LiOH, NaOH or KOH, in solvents, such as MeOH, THF, or a mixture thereof, at temperatures ranging from RT to about 80° C. Alternatively, compounds of Formulae (I) can synthesized directly via a reductive coupling from compounds of Formulae (IV) using the corresponding aldehyde or hemiacetal. This reaction is accomplished in the presence of a reducing agent, such as sodium dithionite, in a solvent, such as DMA.
Alternatively, compounds of Formulae (IV) could be obtained by alkylation of 4-amino-3-nitrophenol (VII) using analogous conditions stated above to provide (VI). Alkylation with suitable aryl or heteroaryl halomethanes in the presence of a base, such as (iPr)2NEt or Et3N, in a solvent, such as CH3CN, at a temperature ranging from about 50° C. to about 150° C., provides compounds of Formulae (IV). Additionally, compounds of Formulae (IV) can be obtained via reductive amination of (VI). Reductive aminations are performed using the appropriate aryl or heteroaryl aldehyde in the presence of a reductant, such as Na(OAc)3BH or NaB(CN)H3, in solvents, such as dichloromethane (DCM), dichloroethane (DCE), or THF or mixtures thereof.




Referring to Scheme B, in alternative embodiments, benzimidazoles of Formulae (I) are obtained by alkylation and hydrolysis of phenol (XI). Phenols (XI) are prepared from an intermediate (VIII), wherein the phenol is protected with an appropriate protecting group, such as methyl, and the amino group alkylated, either by an SN2 process or by reductive amination, using conditions described above to afford (IX). Reduction of the nitro group of (IX) to afford diamines (X) can be performed using conditions described above. Cyclization of (X) to afford (XI) can be performed using methods described above, The protecting group on the phenol of compounds of Formulae (X) may be removed using generally accepted methods. More specifically, when the protecting group is methyl, compounds of Formulae (XI) can be prepared using an appropriate reagent, such as BBr3, in a solvent, such as DCM, at a temperature ranging from −78° C. to RT. Alkylation of (XI) and hydrolysis of the ester of R5, if present, are performed using methods described in Scheme A.




Referring to Scheme C, compounds of Formulae (I) can be obtained by N-alkylation of one of the benzimidazole (XIII) nitrogens followed by hydrolysis of the ester substituent of R5. Benzimidazole (XIII) can be obtained from diamines XII using known procedures described in Scheme A. Reduction of the nitro group of (VI) using methods described above affords diamine (XII). Cyclization of (XII) to give (XIII) can be performed using conditions described above. Alkylation is performed with the desired aryl- or heteroaryl methylene halide in the presence of a base, such as K2CO3, Cs2CO3, or NaOH, a suitable polar solvent, such as CH3CN, DMF, DMA, THF, or a mixture thereof, at a temperature ranging from about RT to about 180° C. Hydrolysis of the ester group R5 can be performed using procedures described above.




Referring to Scheme D, benzimidazoles (XIV), where X1, X2 or X3 is an appropriate halogen, preferably Br, and substituent R5 is protected as an ester, can be coupled with various amines, aryls, and heteroaryls using known organometallic cross coupling methods. Coupling of the aromatic halides (XIV) with various amines, boronic acids, boronic esters, and stannanes in the presence of a catalyst, such as Pd(dppf)Cl2.CH2Cl2, Pd(OAc)2, Pd(PPh3)4, or RuPhos/RuPhos pre-catalyst, in a solvent, such as THF, 1,4-dioxane, DMA, DMF, DME, or toluene, in the presence of a base, such as NaOt-Bu, LiHMDS, Na2CO3, K2CO3, Cs2CO3, or K3PO4, affords esters of benzamidazole (I). Preferred catalysts for amination include Pd(dppf)Cl2.CH2Cl2 and RuPhos/RuPhos pre-catalyst with K3PO4, NaOt-Bu or LiHMDS in 1,4-dioxane, toluene, or THF at temperatures ranging from about RT to the boiling point of the solvent. In instances where R5 contains an alkyl ester, hydrolysis using methods described above provides (I).

Where the processes for the preparation of the compounds according to the invention give rise to mixtures of stereoisomers, these isomers may be separated by conventional techniques such as preparative chromatography. The compounds may be prepared in racemic form or as individual enantiomers or diasteromers by either stereospecific synthesis or by resolution. The compounds may, for example, be resolved into their component enantiomers or diastereomers by standard techniques, such as the formation of stereoisomeric pairs by salt formation with an optically active base, followed by fractional crystallization and regeneration of the free acid. The compounds may also be resolved by formation of stereoisomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using a chiral HPLC column. It is to be understood that all stereoisomers, racemic mixtures, diastereomers, cis-trans isomers, and enantiomers thereof are encompassed within the scope of the present invention.
E) USE
Dosages
For preparing pharmaceutical compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical carrier, e.g. conventional tableting ingredients such as diluents, binders, adhesives, disintegrants, lubricants, antiadherents and gildants. Suitable diluents include, but are not limited to, starch (i.e. corn, wheat, or potato starch, which may be hydrolized), lactose (granulated, spray dried or anhydrous), sucrose, sucrose-based diluents (confectioner's sugar; sucrose plus about 7 to 10 weight percent invert sugar; sucrose plus about 3 weight percent modified dextrins; sucrose plus invert sugar, about 4 weight percent invert sugar, about 0.1 to 0.2 weight percent cornstarch and magnesium stearate), dextrose, inositol, mannitol, sorbitol, microcrystalline cellulose (i.e. AVICELTM microcrystalline cellulose available from FMC Corp.), dicalcium phosphate, calcium sulfate dihydrate, calcium lactate trihydrate and the like. Suitable binders and adhesives include, but are not limited to acacia gum, guar gum, tragacanth gum, sucrose, gelatin, glucose, starch, and cellulosics (i.e. methylcellulose, sodium carboxymethylcellulose, ethylcellulose, hydroxypropylmethylcellulose, hydroxypropylcellulose, and the like), water soluble or dispersible binders (i.e. alginic acid and salts thereof, magnesium aluminum silicate, hydroxyethylcellulose [i.e. TYLOSETM available from Hoechst Celanese], polyethylene glycol, polysaccharide acids, bentonites, polyvinylpyrrolidone, polymethacrylates and pregelatinized starch) and the like. Suitable disintegrants include, but are not limited to, starches (corn, potato, etc.), sodium starch glycolates, pregelatinized starches, clays (magnesium aluminum silicate), celluloses (such as crosslinked sodium carboxymethylcellulose and microcrystalline cellulose), alginates, pregelatinized starches (i.e. corn starch, etc.), gums (i.e. agar, guar, locust bean, karaya, pectin, and tragacanth gum), crosslinked polyvinylpyrrolidone and the like. Suitable lubricants and antiadherents include, but are not limited to, stearates (magnesium, calcium and sodium), stearic acid, talc waxes, stearowet, boric acid, sodium chloride, DL-leucine, carbowax 4000, carbowax 6000, sodium oleate, sodium benzoate, sodium acetate, sodium lauryl sulfate, magnesium lauryl sulfate and the like. Suitable gildants include, but are not limited to, talc, cornstarch, silica (i.e. CAB-O-SILTM silica available from Cabot, SYLOIDTM silica available from W. R. Grace/Davison, and AEROSILTM silica available from Degussa) and the like. Sweeteners and flavorants may be added to chewable solid dosage forms to improve the palatability of the oral dosage form. Additionally, colorants and coatings may be added or applied to the solid dosage form for ease of identification of the drug or for aesthetic purposes. These carriers are formulated with the pharmaceutical active to provide an accurate, appropriate dose of the pharmaceutical active with a therapeutic release profile.
Generally these carriers are mixed with the pharmaceutical active to form a solid preformulation composition containing a homogeneous mixture of the pharmaceutical active form of the present invention, or a pharmaceutically acceptable salt thereof. Generally the preformulation will be formed by one of three common methods: (a) wet granulation, (b) dry granulation and (c) dry blending. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective dosage forms such as tablets, pills and capsules. This solid preformulation composition is then subdivided into unit dosage forms of the type described above containing from about 0.1 mg to about 500 mg of the active ingredient of the present invention. The tablets or pills containing the novel compositions may also be formulated in multilayer tablets or pills to provide a sustained or provide dual-release products. For example, a dual release tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer, which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric materials such as shellac, cellulose acetate (i.e. cellulose acetate phthalate, cellulose acetate trimetllitate), polyvinyl acetate phthalate, hydroxypropyl methylcellulose phthalate, hydroxypropyl methylcellulose acetate succinate, methacrylate and ethylacrylate copolymers, methacrylate and methyl methacrylate copolymers and the like. Sustained release tablets may also be made by film coating or wet granulation using slightly soluble or insoluble substances in solution (which for a wet granulation acts as the binding agents) or low melting solids a molten form (which in a wet granulation may incorporate the active ingredient). These materials include natural and synthetic polymers waxes, hydrogenated oils, fatty acids and alcohols (i.e. beeswax, carnauba wax, cetyl alcohol, cetylstearyl alcohol, and the like), esters of fatty acids metallic soaps, and other acceptable materials that can be used to granulate, coat, entrap or otherwise limit the solubility of an active ingredient to achieve a prolonged or sustained release product.
The liquid forms in which the novel compositions of the present invention may be incorporated for administration orally or by injection include, but are not limited to aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Suitable suspending agents for aqueous suspensions, include synthetic and natural gums such as, acacia, agar, alginate (i.e. propylene alginate, sodium alginate and the like), guar, karaya, locust bean, pectin, tragacanth, and xanthan gum, cellulosics such as sodium carboxymethylcellulose, methylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropyl cellulose and hydroxypropyl methylcellulose, and combinations thereof, synthetic polymers such as polyvinyl pyrrolidone, carbomer (i.e. carboxypolymethylene), and polyethylene glycol; clays such as bentonite, hectorite, attapulgite or sepiolite; and other pharmaceutically acceptable suspending agents such as lecithin, gelatin or the like. Suitable surfactants include but are not limited to sodium docusate, sodium lauryl sulfate, polysorbate, octoxynol-9, nonoxynol-10, polysorbate 20, polysorbate 40, polysorbate 60, polysorbate 80, polyoxamer 188, polyoxamer 235 and combinations thereof. Suitable deflocculating or dispersing agents include pharmaceutical grade lecithins. Suitable flocculating agents include but are not limited to simple neutral electrolytes (i.e. sodium chloride, potassium, chloride, and the like), highly charged insoluble polymers and polyelectrolyte species, water soluble divalent or trivalent ions (i.e. calcium salts, alums or sulfates, citrates and phosphates (which can be used jointly in formulations as pH buffers and flocculating agents). Suitable preservatives include but are not limited to parabens (i.e. methyl, ethyl, n-propyl and n-butyl), sorbic acid, thimerosal, quaternary ammonium salts, benzyl alcohol, benzoic acid, chlorhexidine gluconate, phenylethanol and the like. There are many liquid vehicles that may be used in liquid pharmaceutical dosage forms; however, the liquid vehicle that is used in a particular dosage form must be compatible with the suspending agent(s). For example, nonpolar liquid vehicles such as fatty esters and oils liquid vehicles are best used with suspending agents such as low HLB (Hydrophile-Lipophile Balance) surfactants, stearalkonium hectorite, water insoluble resins, water insoluble film forming polymers and the like. Conversely, polar liquids such as water, alcohols, polyols and glycols are best used with suspending agents such as higher HLB surfactants, clays silicates, gums, water soluble cellulosics, water soluble polymers and the like. For parenteral administration, sterile suspensions and solutions are desired. Liquid forms useful for parenteral administration include sterile solutions, emulsions and suspensions. Isotonic preparations which generally contain suitable preservatives are employed when intravenous administration is desired.
Furthermore, compounds of the present invention can be administered in an intranasal dosage form via topical use of suitable intranasal vehicles or via transdermal skin patches, the composition of which are well known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the administration of a therapeutic dose will, of course, be continuous rather than intermittent throughout the dosage regimen.
Compounds of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, multilamellar vesicles and the like. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine, phosphatidylcholines and the like.
The daily dose of a pharmaceutical composition of the present invention may be varied over a wide range from about 0.1 mg to about 5000 mg; preferably, the dose will be in the range of from about 1 mg to about 100 mg per day for an average human. For oral administration, the compositions are preferably provided in the form of tablets containing, 0.01, 0.05, 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 25.0, 50.0, 100, 150, 200, 250 or 500 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the subject to be treated. Advantageously, a compound of the present 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.
It is also apparent to one skilled in the art that the therapeutically effective dose for active compounds of the invention or a pharmaceutical composition thereof will vary according to the desired effect. Therefore, optimal dosages to be administered may be readily determined by those skilled in the art, and will vary with the particular compound used, the mode of administration, the strength of the preparation, and the advancement of the disease condition. In addition, factors associated with the particular subject being treated, including subject age, weight, diet and time of administration, will result in the need to adjust the dose to an appropriate therapeutic level. The above dosages are thus exemplary of the average case. There can, of course, be individual instances where higher or lower dosage ranges are merited, and such are within the scope of this invention.
Compounds of this invention may be administered in any of the foregoing compositions and dosage regimens or by means of those compositions and dosage regimens established in the art whenever use of the compounds of the invention as FLAP modulators is required for a subject in need thereof.
In their use, the compounds of the invention may be combined with any other therapeutic agents that are useful for the treatment of an FLAP-mediated disorder.
The combination includes not only the composition of compounds of the invention and one other active substance but also the composition of compounds of the invention and two or more other active substances or non-drug therapy. The scope of possible combinations of a compound of the invention and one, two or more active substances are within the knowledge of one skilled in the art for the treatment of an FLAP-mediated disorder.
Specifically, the combination of a FLAP modulator with prostaglandin modulators, cyclooxygenase-1 modulators, or cyclooxygenase-2 modulators might be used to treat inflammatory and autoimmune diseases and/or disorders as well as cardiovascular diseases and/or disorders, or vascular injury (Z. Yu et al., “Disruption of the 5-lipoxygenase pathway attenuates atherogenesis consequent to COX-2 deletion in mice,” Proc. Natl. Acad. Sci. USA, 2012, 109(17), 6727-32; Z. Yu et al., “Myeloid Cell 5-Lipoxygenase Activating Protein Modulates the Response to Vascular Injury,” Circ. Res., 2012, Epub December 18). Due to the synergy of histamine and leukotrienes, the combination of a FLAP modulator and a histamine receptor 1 or 4 antagonist might have utility in treating respiratory, allergic, dermatological and autoimmune disorders (A. Reicin et al., “Montelukast, a leukotriene receptor antagonist, in combination with loratadine, a histamine receptor antagonist, in the treatment of chronic asthma,” Arch. Intern. Med., 2000, 160(16), 2418-88; S. Sanada et al., “The effectiveness of montelukast for the treatment of anti-histamine-resistant chronic urticaria,” Arch. Dermatol. Res., 2005, 297(3), 134-38).
Formulations
To prepare the pharmaceutical compositions of this invention, one or more compounds of Formula (I) or salt thereof as the active ingredient, is intimately admixed with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques, which carrier may take a wide variety of forms depending of the form of preparation desired for administration (e.g. oral or parenteral). Suitable pharmaceutically acceptable carriers are well known in the art. Descriptions of some of these pharmaceutically acceptable carriers may be found in The Handbook of Pharmaceutical Excipients, published by the American Pharmaceutical Association and the Pharmaceutical Society of Great Britain.
The compounds of the present invention may be formulated into various pharmaceutical forms for administration purposes. Methods of formulating pharmaceutical compositions have been described in numerous publications such as Pharmaceutical Dosage Forms: Tablets, Second Edition, Revised and Expanded, Volumes 1-3, edited by Lieberman et al; Pharmaceutical Dosage Forms: Parenteral Medications, Volumes 1-2, edited by Avis et al; and Pharmaceutical Dosage Forms: Disperse Systems, Volumes 1-2, edited by Lieberman et al; published by Marcel Dekker, Inc.
F) BIOLOGICAL EXAMPLES
The ability of the compounds of the present invention to treat a FLAP-mediated disease and/or disorder, or associated symptoms or complications thereof, was determined using the following procedures. Binding assay data represent the average value obtained from two different assay plates, with samples run in duplicate on each plate. Human whole blood assay data represent a single replicate on an assay plate using whole blood from at least one healthy donor. Certain FLAP binding and human whole blood assay data is presented in Table 2.
FLAP Binding Assay
The assay below is used to test the modulatory activity of compounds against FLAP. Human and mouse FLAP-encoding DNA was amplified by polymerase chain reaction and cloned into pFastBac1 (Invitrogen) with a NH2-terminal 6-His tag for expression in Spodoptera frugiperda (Sf-9) cells. FLAP-containing membranes were prepared as was a FITC-labeled FLAP modulator (3-(3-(tert-butylthio)-1-(4-chlorobenzyl)-5-(quinolin-2-ylmethoxy)-1H-indol-2-yl)-2,2-dimethylpropanoic acid). The FLAP binding assay is performed in HTRF format (homogeneous time resolved fluorescence). FLAP-containing membranes (1 μg/well final for human) are incubated in the presence of the HTRF ligand, [5-[({[2-(2-{3-[3-(tert-butylsulfanyl)-1-(4-chlorobenzyl)-5-(quinolin-2-ylmethoxy)-1H-indol-2-yl]-2,2-dimethylpropanoyl}hydrazino)-2-oxoethyl]sulfanyl}acetyl)amino]-2-(6-hydroxy-3-oxo-3H-xanthen-9-yl)benzoic acid] (25 nM final), a terbium labeled anti-His tag antibody (0.5 ng/well final, from Cisbio) and compounds. The reaction is allowed to proceed for two hours after which the plate is read on an Envision plate reader in HTRF mode. Data are expressed as a HTRF ratio.
For human FLAP binding assays, data are analyzed with 3DX Explorer software. A ratio is calculated with the relative light units at 520 nm over the relative light units at 495 nm. For analysis, data from multiple runs are averaged and each compound may be tested in 2 to 20 runs. Each run comprises two plates and each plate includes duplicates. Data from each plate is averaged and data are imported into 3DX. The data from multiple runs are aggregated as the average of duplicates of the calculated ratios in order to calculate Ki and 1050 values. Numbers in parentheses are the number of runs for the assay.
Human Whole Blood Assay
An in vitro cellular assay was performed using human whole blood collected in heparin-containing tubes, which was used to test the ability of compounds to modulate the leukotriene pathway in human whole blood. The blood was diluted 1:1 in RPMI medium, pre-incubated for 15 min at 37° C. with test compounds at various concentrations, and then stimulated with calcium ionophore, A23187 (7 μg/mL), for 30 min at 37° C. The samples were then centrifuged and plasma was removed. The plasma was diluted in assay buffer and LTB4 levels were measured using a commercial kit (Enzo Life Sciences). The concentration of each compound that was required for half-maximal inhibition (modulation) of recombinant enzyme activity (IC50) was calculated by a 4-parameter equation using the program GraphPad Prism (GraphPad software). Where duplicate assays were performed by the same team, the values were averaged. Numbers in parentheses are the number of runs for the assay.
