The present invention relates to small molecule compounds and their use in the treatment of inflammatory diseases, in particular asthma, chronic obstructive pulmonary disease (COPD), inflammation post infection, arthritis, atherosclerosis, pain and dermatitis.
Inflammation is defined as the response of body tissues to injury or irritation. As such, inflammation is a fundamental, stereotyped complex of cytologic and chemical reactions of affected blood vessels and adjacent tissues in response to an injury or abnormal stimulation caused by a physical, chemical or biological agent. Inflammation usually leads to the accumulation of fluid and blood cells at the site of injury, and is usually a healing process. However, inflammation sometimes causes harm, usually through a dysfunction of the normal progress of inflammation. Inflammatory diseases are those pertaining to, characterized by, causing, resulting from, or becoming affected by inflammation. Examples of inflammatory diseases or disorders include, without limitation, asthma, lung inflammation, COPD, inflammation post infection, atherosclerosis, pain, dermatitis, chronic granulomatous diseases such as tuberculosis, leprosy, sarcoidosis, and silicosis, nephritis, amyloidosis, rheumatoid arthritis, ankylosing spondylitis, chronic bronchitis, scleroderma, lupus, polymyositis, appendicitis, inflammatory bowel disease, ulcers, Sjogren's syndrome, Reiter's syndrome, psoriasis, pelvic inflammatory disease, orbital inflammatory disease, thrombotic disease, and inappropriate allergic responses to environmental stimuli such as poison ivy, pollen, insect stings and certain foods, including atopic dermatitis and contact dermatitis.
There is a need for novel anti-inflammatory agents e.g. drugs that demonstrate improved pharmacokinetics, activity, oral bioavailability, potency or effective half-lives in vivo. Such agents may also have distinct resistance profiles, fewer side effects, less complicated dosing schedules, or have increased oral activity. There is still a need in the art for novel non-steroidal anti-inflammatory drugs (NSAIDs) that do not have the adverse side effects associated with prior art compounds. There is also a need for new and improved treatments of inflammatory diseases states and disorders.
Arachidonate 5-lipoxygenase (5-lipoxygenase, 5-LO or Alox5) is a member of the lipoxygenase family of enzymes. It catalyzes the oxidation of arachidonic acid to yield 5-hydroperoxyeicosatetraenoic acid. 5-LO inhibitors have been developed, mostly unsuccessfully to date, for the treatment of asthma and for rheumatic conditions such as rheumatoid arthritis. There are, however, a few marketed drugs; Zileuton, a 5-LO iron chelating inhibitor, which is an orally active inhibitor that blocks the production of leukotrienes (LTA4, LTB4, LTD4 and LTE4). The product is now marketed in two formulations; the original immediate-release formulation and now the extended-release formulation. The immediate release tablet was withdrawn from the United States market on Feb. 12, 2008. Zileuton's most serious side effect is liver toxicity and hence is not available to patients with liver disease. Montelukast and Zafirlukast are oral leukotriene receptor antagonists (i.e. they block the action of 5-LO enzyme products) used to treat asthma and relieve symptoms of seasonal allergies. Side effects of Montelukast include gastrointestinal disturbances, hypersensitivity reactions, sleep disorders and increased bleeding tendency. Zafirlukast product warning includes notification regarding eosinophilia, vasculitic rash, worsening pulmonary symptioms and/or cardiac complications. There is also some evidence that the use of either Montelukast or Zafirlukas is associated with a higher incidence of Churg-Straus syndrome. Hence improved anti-5-LO enzyme and/or pathway compounds are required for the treatment of inflammationary disorders. Herein are disclosed compounds with anti-inflammatory activity and anti-5-LO activity.
It was an object of the present invention to identify compounds with an inhibitory effect against arachidonate 5-lipoxygenase.
It was an object of the present invention to identify compounds effective against inflammatory disease, in particular asthma, atherosclerosis, pain, COPD, inflammation post infection, arthritis, and dermatitis.

Administration and Formulation
The production of medicaments containing the compounds of the invention, its active metabolites or isomers and salts according to the invention and their application can be performed according to well-known pharmaceutical methods.
While the compounds of the invention, useable according to the invention for use in therapy, may be administered in the form of the raw chemical compound, it is preferred to introduce the active ingredient, optionally in the form of a physiologically acceptable salt in a pharmaceutical composition together with one or more adjuvants, excipients, carriers, buffers, diluents, and/or other customary pharmaceutical auxiliaries. Such salts of the compounds of the invention may be anhydrous or solvated.
In a preferred embodiment, the invention provides medicaments comprising a compound useable according to the invention, or a pharmaceutically acceptable salt or derivative thereof, together with one or more pharmaceutically acceptable carriers therefor, and, optionally, other therapeutic and/or prophylactic ingredients. The carrier(s) must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not harmful to the recipient thereof.
A medicament of the invention may be those suitable for oral, rectal, bronchial, nasal, topical, buccal, sub-lingual, transdermal, vaginal or parenteral (including cutaneous, subcutaneous, intramuscular, intraperitoneal, intravenous, intraarterial, intracerebral, intraocular injection or infusion) administration, or those in a form suitable for administration by inhalation or insufflation, including powders and liquid aerosol administration, or by sustained release systems. Suitable examples of sustained release systems include semipermeable matrices of solid hydrophobic polymers containing the compound of the invention, which matrices may be in form of shaped articles, e.g. films or microcapsules.
The compounds useable according to the invention, together with a conventional adjuvant, carrier, or diluent, may thus be placed into the form of medicament and unit dosages thereof. Such forms include solids, and in particular tablets, filled capsules, powder and pellet forms, and liquids, in particular aqueous or non-aqueous solutions, suspensions, emulsions, elixirs, and capsules filled with the same, all for oral use, suppositories for rectal administration, and sterile injectable solutions for parenteral use. Such medicament and unit dosage forms thereof may comprise conventional ingredients in conventional proportions, with or without additional active compounds or principles, and such unit dosage forms may contain any suitable effective amount of the active ingredient commensurate with the intended daily dosage range to be employed.
The compounds useable according to the invention can be administered in a wide variety of oral and parenteral dosage forms. It will be obvious to those skilled in the art that the following dosage forms may comprise, as the active component, either a compound(s) useable according to the invention or a pharmaceutically acceptable salt of a compound(s) useable according to the invention.
For preparing a medicament from a compound useable according to the invention, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances which may also act as diluents, flavouring agents, solubilizers, lubricants, suspending agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.
In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component. In tablets, the active component is mixed with the carrier having the necessary binding capacity in suitable proportions and compacted in the shape and size desired. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term “preparation” is intended to include the formulation of the active compound with encapsulating material as carrier providing a capsule in which the active component, with or without carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid forms suitable for oral administration.
For preparing suppositories, a low melting wax, such as a mixture of fatty acid glyceride or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogenous mixture is then poured into convenient sized moulds, allowed to cool, and thereby to solidify. Compositions suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or sprays containing in addition to the active ingredient such carriers as are known in the art to be appropriate. Liquid preparations include solutions, suspensions, and emulsions, for example, water or water-propylene glycol solutions. For example, parenteral injection liquid preparations can be formulated as solutions in aqueous polyethylene glycol solution.
The chemical compounds according to the present invention may thus be formulated for parenteral administration (e.g. by injection, for example bolus injection or continuous infusion) and may be presented in unit dose form in ampoules, pre-filled syringes, small volume infusion or in multi-dose containers with an added preservative. The compositions may take such forms as suspensions, solutions, or emulsions in oily or aqueous vehicles, and may contain formulation agents such as suspending, stabilising and/or dispersing agents. Alternatively, the active ingredient may be in powder form, obtained by aseptic isolation of sterile solid or by lyophilization from solution, for constitution with a suitable vehicle, e.g. sterile, pyrogen-free water, before use.
Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavours, stabilising and thickening agents, as desired. Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, or other well known suspending agents.
Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavours, stabilisers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.
In one embodiment of the present invention, the medicament is applied topically or systemically or via a combination of the two routes.
For administration, the compounds of the present invention may, in one embodiment, be administered in a formulation containing 0.001% to 70% per weight of the compound, preferably between 0.01% to 70% per weight of the compound, even more preferred between 0.1% and 70% per weight of the compound. In one embodiment, a suitable amount of compound administered is in the range of 0.01 mg/kg body weight to 1 g/kg body weight.
Compositions suitable for administration also include lozenges comprising the active agent in a flavoured base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerol or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.
Solutions or suspensions are applied directly to the nasal cavity by conventional means, for example with a dropper, pipette or spray. The compositions may be provided in single or multi-dose form. In the latter case of a dropper or pipette, this may be achieved by the patient administering an appropriate, predetermined volume of the solution or suspension. In the case of a spray, this may be achieved for example by means of a metering atomising spray pump.
Administration to the respiratory tract may also be achieved by means of an aerosol formulation in which the active ingredient is provided in a pressurised pack with a suitable propellant such as a chlorofluorocarbon (CFC) for example dichlorodifluoromethane, trichlorofluoromethane, or dichlorotetrafluoroethane, carbon dioxide, or other suitable gas. The aerosol may conveniently also contain a surfactant such as lecithin. The dose of drug may be controlled by provision of a metered valve.
Alternatively the active ingredients may be provided in the form of a dry powder, for example a powder mix of the compound in a suitable powder base such as lactose, starch, starch derivatives such as hydroxypropylmethyl cellulose and polyvinylpyrrolidone (PVP). Conveniently the powder carrier will form a gel in the nasal cavity. The powder composition may be presented in unit dose form for example in capsules or cartridges of, e.g., gelatin, or blister packs from which the powder may be administered by means of an inhaler.
In compositions intended for administration to the respiratory tract, including intranasal compositions, the compound will generally have a small particle size for example of the order of 5 microns or less. Such a particle size may be obtained by means known in the art, for example by micronization.
When desired, compositions adapted to give sustained release of the active ingredient may be employed.
The pharmaceutical preparations are preferably in unit dosage forms. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packaged tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form. Tablets or capsules for oral administration and liquids for intravenous administration and continuous infusion are preferred compositions.

The invention is now further described by reference to the following examples which are intended to illustrate, not to limit the scope of the invention.
The activity of compounds against 5-LO were determined by measuring LTB4 (leukotriene B4) levels and/or by a fluorescence method. Both approaches are outlined in more detail below;
LTB4 Measurement:
Human 5-lipoxygenase (Cayman, Cat#60402) produced in insect cells was pre-incubated with compound for 15 min at RT in incubation buffer (50 mM Tris-Cl, pH 7.4, 2 mM CaCl2, 0.1 mM ATP, 1% DMSO). The enzymatic reaction was started by adding arachidonic acid to a final concentration of 3 uM. After 5 min of incubation at 37° C., the reaction was stopped by heatinactivation at 80° C. for 5 min. LTB4 levels were quantified by using LTB4 EIA kit (Cayman, Cat#520111) as instructed and/or LTB4 levelswere measured with LC/MS/MS using Quattro Premier™ XE tandem quadrupole mass spectrometer equipped with Acquity UPLC system (Waters, Milford, Mass.). The method was slightly modified as reported previously (Zweifel et al., 2008, Willey et al., 2008, Chappell et al, 2011). Briefly, chromatographic separation was carried out with Acquity UPLC BEH Shield RP18 Column (2.1 mm×50 mm, 1.7 μm particle size, Waters, Milford, Mass.). Sample injection volume was 10 μl, the column temperature was 35° C., the mobile phase A consisted of water with 0.1% formic acid and the mobile phase B consisted of acetonitrile with 0.1% formic acid. Flow rate was 0.4 mL/min and the gradient condition was as follows.
Relative quantification of LTB4 and LTB4-d4 (Internal Standard) was done using multi reaction monitoring (MRM) of the transitions of m/z 335→195 for LTB4, 339→197 for LTB4-d4 in electrospray ionization (ESI) negative mode. Desolvation temperature was 400° C., source temperature was 130° C. Capillary voltage, cone voltage, and collision voltage were 3.5 kV, 30V, and 20 eV, respectively. Nitrogen was used for desolvation (750 L/h) and cone (50 L/h) gas. Argon was used for collision gas (0.22 ml/min). The dwell time was 10 ms.
Fluoresence Method:
Besides the two methods quantifying LTB4 level, a fluorescence assay measuring 5-HpETE was introduced for high-throughput screening in a 384 well microplate format (Pufahl et al., 2007). For nonspecific ester cleavage of the acetate groups in H2DCFDA, the insect cell lysate expressing human 5-LO (Cayman Cat#60402) was incubated with H2DCFDA (50 mM Tris-Cl, pH 7.5, 2 mM CaCl2, 20 uM H2DCFDA, 500 mU 5-LO per reaction) for 5 minutes. Compound and enzyme mixture were pre-incubated for 5 minutes, and the enzymatic reaction was initiated by addition of ATP and arachidonic acid to a final concentration of 100 uM and 3 uM, respectively. After 5 minutes of incubation, the fluorescence was measured using Spectramax M5 (Molecular Device, Ex/Em=485 nm/530 nm). All steps were carried out at room temperature.
A total of 378 compounds were initially tested at a single concentration of 10 uM in duplicate with the results summarized in Table 1. From these 378 compounds, 53 compounds plus an additional 25 were selected for confirmation of activity by 6 or 11 point dose response in duplicate with the corresponding IC50 values outlined in Table 2. These results demonstrate that the imidazopyridine derivatives are potent inhibitors of the 5-LO enzyme.
Frozen human PBMC (peripheral blood mononuclear cells, AllCells, Cat#PB006F) was diluted 50 times with fresh culture media (RPMI 1640 supplemented with 10% FBS, 2 mM L-alanyl-L-glutamine). Cells were harvested by centrifugation and resuspended in fresh culture media to a concentration of 5×106 cells per milliliter. 140 ul of cell suspension was then liquated to each well (96-well plate). After incubation at 37° C. for 1 hr under 5% CO2, 10 ul of serially diluted compounds (in 100% DMSO) and 10 ul of arachidonic acid to a final concentration of 30 uM were added and further incubated for 1 hr at 37° C. for 1 hr under 5% CO2. Then, inducers, such as A23187 (Ionophor), sodium arsenite, sodium chloride and/or Anti-DNP IgE, were added in a volume of 40 ul and cells were incubated at 37° C. for 1 hr under 5% CO2 for 30 min. Culture supernatant was harvested by centrifugation and LTB4 levels were quantified using LTB4 EIA kit (Cayman, Cat#520111).
Six of the 378 compounds tested against the 5-LO enzyme in vitro were also selected to be tested for their activity in a human cellular assay. Compounds were tested in a 12 point dose response in duplicate. The EC50 results from this assay are summarized in Table 3. These results confirm the findings from Example 1 in that these compounds are inhibitors of the 5-LO enzyme. These findings also demonstrate that the imidazopyridine derivatives are strong inhibitors of the 5-LO enzyme in an in vivo human cellular assay system.
Previously, the imidazopyridine derivatives have demonstrated in vivo activity against Mycobacterium tuberculosis (TB). Histopathological evidence demonstrated that these compounds, in addition to having anti-TB activity, also demonstrated anti-inflammatory activity.
The effect of compound 127 on TB-infected mice was compared to that of the reference compound Isoniazid (INH). 8-week old female BalbC mice were infected with 6×105 M. tuberculosis H37Rv via intranasal instillation. Mice were sacrificed at day 1 to control the number of CFU in the lungs. In the acute model of infection, mice were treated for 4 weeks, starting at day 1. Compounds were freshly dissolved in a 0.5% methylcellulose solution and administered by oral gavage 5 times/week. Bacterial load was assessed in lungs after homogenizing the organs in 1×PBS. Serial dilutions of organ homogenates were spread on Middlebrook 7H11 plates and CFU were determined after 3 weeks incubation at 37° C. under 5% CO2. Histopathological analysis of lung tissue was performed by Hematoxylin and Eosin staining.
In the acute model of infection (after 4 weeks of treatment; Table 4), a reduction of ˜1 log CFU compared to untreated mice was observed in the lungs of mice treated with 50 mg/kg of compound 127. In addition, notably, was a significant reduction in the number and size of inflammatory lesions in the lungs (
Taken together, these data demonstrate that the imidazopyridine derivatives have an anti-inflammation effect and mediate, at least partially, this effect through their activity on the 5-LO enzyme.
The imidazopyridine compounds (scaffold I; see Tables 1 and/or 2) underwent derivatization according to the methods outlined below (Schemes 1-15). Resulting derivatives were examined for inhibitory activity (single point, IC50, EC50, in vivo) using the assays described above (Examples 1, 2 and 3) and the results are summarized in Tables 1, 2, 3 and 4 and
