TREATMENT OF ASTHMA WITH MEK INHIBITORS

Abstract: This invention provides a method of preventing or treating asthma by administering to a patient in need of treatment an effective amount of a selective MEK inhibitor, especially a phenyl amine of Formula (I) and (II).

Description: TREATMENT OF ASTHMA WITH MEK INHIBITORS FIELD OF THE INVENTION This invention relates to a method for preventing and treating asthma in mammals comprising administering a compound characterized as an inhibitor of a family of enzymes known as MEK kinases, which are groups of MAP (mitogen- associated protein kinase) and Erk (extracellular signal-regulated) Kinases. These are enzymes that regulate phosphorylation of substrates in mammals. BACKGROUND OF THE INVENTION Asthma is a heterogeneous disorder of the airways that afflicts millions of people. Airway inflammation, hyperresponsiveness, and obstruction characterize the condition. The disease often causes spasms of the bronchial smooth muscle system, and affects both the upper and lower respiratory tracts. There are several forms of asthma, characterized by varying degrees of severity. Mild asthma, for example, is defined as brief episodes of wheezing, with or without dyspnea or cough. Moderately severe asthma is defined as wheezing and dyspnea, and can be with or without cough and expectoration, but generally interferes with daily activities and/or sleeping. Severe asthma is characterized by incapacitation due to dyspnea, and the afflicted patient typically is unable to eat or sleep normally, is very anxious, and is often exhausted. A condition known as status asthmaticus is the most severe form of asthma, and generally requires intensive hospital care, and may even prove fatal. The disease may occur as a result of both allergic and nonallergic mechanisms. While there are several treatments available for relieving the symptoms and discomfort associated with asthma, there are no cures. Moreover, the current treatments often cause side effects that exacerbate the discomfort and precipitate other debilitating conditions. Mild asthma generally is treated with beta- adrenergic drugs, as well as antihistamines, especially in the case of children, to prevent or abort sporadic episodes. Moderately severe and severe asthma are generally treated with adrenergic agents and bronchodilators, as well as corticosteroids. Other actions caused by antiasthmatic agents which limit their widespread use include headache, fatigue, dry mouth, nervousness, and in some cases addiction and substance abuse. Recent advances in the understanding of the pathogenesis and treatment of asthma is discussed more fully by Grayson et al., The Mount Sinai Journal of Medicine, Sept. 1998;65(4):246-256. Because asthma is so prevalent in both children and adults, there is an ongoing need for agents that can treat the disease, or at least relieve the symptoms that accompany the disease, without causing undesirable side effects. We have now discovered that MEK inhibitors are particularly useful for treating asthma and relieving the symptoms that accompany the disease. An object of this invention is therefore to provide a new method for preventing and treating asthmatic conditions. SUMMARY OF THE INVENTION This invention provides a method of preventing and treating asthma, said method comprising the step of administering to a patient an antiasthmatic- effective amount of a MEK inhibitor. Selective MEK inhibitors are those compounds which inhibit the MEK 1 and MEK 2 enzymes without substantial inhibition of other such enzymes. In a preferred embodiment, the invention provides a method for preventing or treating asthma by administering a MEK inhibitor. In a further embodiment, the invention provides a method for preventing and/or treating asthma comprising administering an effective amount of the selective MEK inhibitor described in US 5,525,625, incorporated herein by reference, which selective MEK inhibitor is 2-(2-amino-3-methoxyphenyl)-4-oxo- 4H-[l]benzopyran. In another preferred embodiment, the MEK inhibitor to be administered is a phenyl amine derivative of Formula I: In Formula (I), Rj is hydrogen, hydroxy, Cj-Cg alkyl, Cj-Cg alkoxy, halo, trifluoromethyl, or CN. R2 is hydrogen.

Preferably, a selective inhibitor has an IC 50 that is at least 1/100, more preferably 1/500, and even more preferably 1/1000, 1/5000, or less than that of its IC 50 or one or more of the above- named enzymes. B. Administration and Formulation The MEK inhibitors of the present method can be administered to a patient as part of a pharmaceutically acceptable composition. The compositions can be administered to humans and animals either orally, rectally, parenterally (intravenously, intramuscularly,or subcutaneously), intracisternally, intravaginally, intraperitoneally, intravesically, locally (powders, ointments, or drops), or as a buccal or nasal spray. Compositions suitable for parenteral injection may comprise physiologically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents, or vehicles include water, ethanol, polyols (propyleneglycol, polyethyleneglycol, glycerol, and the like), suitable mixtures thereof, vegetable oils (such as olive oil), and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions and by the use of surfactants. These compositions may also contain adjuvants such as preserving, wetting, emulsifying, and dispensing agents. Prevention of the action of microorganisms can be ensured by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example sugars, sodium chloride, and the like. Prolonged absoφtion of the injectable pharmaceutical form can be brought about by the use of agents delaying absoφtion, for example, aluminum monostearate and gelatin. Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is admixed with at least one inert customary excipient (or carrier) such as sodium citrate or dicalcium phosphate or (a) fillers or extenders, as for example, starches, lactose, sucrose, glucose, mannitol, and silicic acid, (b) binders, as for example, carboxymethylcellulose, alignates, gelatin, polyvinylpyrrolidone, sucrose, and acacia, (c) humectants, as for example, glycerol, (d) disintegrating agents, as for example, agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain complex silicates, and sodium carbonate, (e) solution retarders, as for example paraffin, (f) absoφtion accelerators, as for example, quaternary ammonium compounds, (g) wetting agents, as for example, cetyl alcohol and glycerol monostearate, (h) adsorbents, as for example, kaolin and bentonite, and (i) lubricants, as for example, talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, or mixtures thereof. In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethyleneglycols, and the like. Solid dosage forms such as tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells, such as enteric coatings and others well- known in the art. They may contain opacifying agents, and can also be of such composition that they release the active compound or compounds in a certain part of the intestinal tract in a delayed manner. Examples of embedding compositions which can be used are polymeric substances and waxes. The active compounds can also be in micro-encapsulated form, if appropriate, with one or more of the above-mentioned excipients. Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art, such as water or other solvents, solubilizing agents and emulsifiers, as for example, ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propyleneglycol, 1,3-butyleneglycol, dimethylformamide, oils, in particular, cottonseed oil, groundnut oil, corn germ oil, olive oil, castor oil and sesame oil, glycerol, tetrahydrofurfuryl alcohol, polyethyleneglycols, and fatty acid esters of sorbitan or mixtures of these substances, and the like. Besides such inert diluents, the composition can also include adjuvants, such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. Suspensions, in addition to the active compounds, may contain suspending agents, as for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, or mixtures of these substances, and the like. Compositions for rectal administrations are preferably suppositories which can be prepared by mixing the compounds of the present invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethyleneglycol, or a suppository wax, which are solid at ordinary temperatures but liquid at body temperature and therefore, melt in the rectum or vaginal cavity and release the active component. Dosage forms for topical administration of a compound of this invention include ointments, powders, sprays, and inhalants. The active component is admixed under sterile conditions with a physiologically acceptable carrier and any preservatives, buffers, or propellants as may be required. Ophthalamic formulations, eye ointments, powders, and solutions are also contemplated as being within the scope of this invention. The compounds of the present method can be administered to a patient at dosage levels in the range of about 0.1 to about 1000 mg per day. For a normal human adult having a body weight of about 70 kg, a dosage in the range of about 0.01 to about 100 mg per kg of body weight per day is preferable. The specific dosage used, however, can vary. For example, the dosage can depend on a numbers of factors including the requirements of the patient, the severity of the condition being treated, and the pharmacological activity of the compound being used. The determination of optimum dosages for a particular patient is well- known to those skilled in the art.

In addition, the compounds of the present method can exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. In general, the solvated forms are considered equivalent to the unsolvated forms for the puφoses of the present invention. Some of the compounds of the present method can exist in different stereoisometric forms by virtue of the presence of chiral centers. It is contemplated that all stereoisometric forms of the compounds as well as mixtures thereof, including racemic mixtures, form part of this invention. C. Synthesis The examples presented below are intended to illustrate particular embodiments of the invention and are not intended to limit the scope of the specification, including the claims, in any way. After the priority date of the present disclosure, related syntheses and MEK inhibition data were also published in WO 99/01421 and WO 99/01426, hereby incoφorated by reference. The 2-(4-bromo and 4-iodo phenylamino)-benzoic acid derivatives of Formula I can be prepared from commercially available starting materials utilizing synthetic methodologies well-known to those skilled in organic chemistry. A typical synthesis is carried out by reacting a 4-bromo or 4-iodo aniline with a benzoic acid having a leaving group at the 2-position to give a 2-(phenylamino)- benzoic acid. This process is depicted in Scheme 1. Scheme 1 base where L is a leaving group, for example halo such as fluoro. The reaction of aniline and the benzoic acid derivative generally is accomplished by mixing the benzoic acid with an equimolar quantity or excess of the aniline in an unreactive organic solvent such as tetrahydrofuran or toluene, in the presence of a base such as lithium diisopropylamide, n-butyl lithium, sodium hydride, triethylamine, and Hunig's base. The reaction generally is carried out at a temperature of about -78°C to about 100°C, and normally is complete within about 2 hours to about 4 days. The product can be isolated by removing the solvent, for example by evaporation under reduced pressure, and further purified, if desired, by standard methods such as chromatography, crystallization, or distillation. The 2-(phenylamino)-benzoic acid (e.g., Formula I, where R7 is hydrogen) can be reacted with an organic or inorganic base such as pyridine, triethylamine, calcium carbonate, or sodium hydroxide to produce a pharmaceutically acceptable salt. The free acids can also be reacted with an alcohol of the formula HOR7 (where R7 is other than hydrogen, for example methyl) to produce the corresponding ester. Reaction of the benzoic acid with an alcohol can be carried out in the presence of a coupling agent. Typical coupling reagents include 2-ethoxy- 1 -ethoxycarbonyl- 1 ,2-dihydroquinoline (EEDQ), 1,3-dicyclohexylcarbodiimide (DCC), bromo-tris(pyrrolidino)- phosphonium hexafluorophosphate (PyBrOP), and (benzotriazolyloxy) tripyrrolidino phosphonium hexafluorophosphate (PyBOP). The phenylamino benzoic acid and alcohol derivative normally are mixed in approximately equimolar quantities in an unreactive organic solvent such as dichloromethane, tetrahydrofuran, chloroform, or xylene, and an equimolar quantity of the coupling reagent is added. A base such as triethylamine or diisopropylethylamine can be added to act as an acid scavenger if desired. The coupling reaction generally is complete after about 10 minutes to 2 hours, and the product is readily isolated by removing the reaction solvent, for instance by evaporation under reduced pressure, and purifying the product by standard methods such as chromatography or crystallizations from solvents such as acetone, diethyl ether, or ethanol. The benzamides of the invention, Formula I where Z is CONR6R7, are readily prepared by reacting the foregoing benzoic acids with an amine of the formula HNR6R7. The reaction is carried out by reacting approximately equimolar quantities of the benzoic acid and amine in an unreactive organic solvent in the presence of a coupling reagent. Typical solvents are chloroform, dichloromethane, tetrahydrofuran, benzene, toluene, and xylene. Typical coupling reagents include DCC, EEDQ, PyBrOP, and PyBOP. The reaction is generally complete after about 10 minutes to about 2 hours when carried out at a temperature of about 0°C to about 60°C. The product amide is readily isolated by removing the reaction solvent, for instance by evaporation, and further purification can be accomplished by normal methods such as chromatography, crystallization, or distillation. The hydrazides (z = CONHNR1.3R11) are similarly prepared by coupling a benzoic acid with a hydrazine of the formula H2HNR10R11. The benzyl alcohols of the invention, compounds of Formula I where Z is CH2OR6 and Rβ is hydrogen, are readily prepared by reduction of the corresponding benzoic acid according to the following Scheme 2. Scheme 2 Typical reducing agents commonly employed include borane in tetrahydrofuran. The reduction normally is carried out in an unreactive organic solvent such as tetrahydrofuran, and generally is complete within about 2 hours to about 24 hours when conducted at a temperature of about 0°C to about 40°C. The following detailed examples illustrate specific compounds provided by this invention.

The following tetrazole substituted phenylamines were prepared by following the general procedure of Example 207. EXAMPLE 208 (4-iodo-2-methyl-phenyl -r2-(lH-tetrazol-5-vπ-phenyl]amine, mp 231°C (dec) EXAMPLE 209 r4-nitro-2-riH-tetrazol-5-yl -(4-iodo-2-methyl-phenyl)-amine, mτ> 205-208°C. The 4-bromo and 4-iodo phenylamino benzhydroxamic acid derivatives of Formula II can be prepared from commercially available starting materials utilizing synthetic methodologies well-known to those skilled in organic chemistry. A typical synthesis is carried out by reacting a 4-bromo or 4-iodo aniline with a benzoic acid having a leaving group at the 2-position to give a phenylamino benzoic acid, and then reacting the benzoic acid phenylamino derivative with a hydroxylamine derivative (Scheme 3), where L is a leaving group, for example halo such as fluoro, chloro, bromo or iodo, or an activated hydroxy group such as a diethylphosphate, trimethylsilyloxy, p-nitrophenoxy, or phenylsulfonoxy. The reaction of aniline and the benzoic acid derivative generally is accomplished by mixing the benzoic acid with an equimolar quantity or excess of the aniline in an unreactive organic solvent such as tetrahydrofuran, or toluene, in the presence of a base such as lithium diisopropylamide, n-butyl lithium, sodium hydride, and sodium amide. The reaction generally is carried out at a temperature of about -78°C to about 25°C, and normally is complete within about 2 hours to about 4 days. The product can be isolated by removing the solvent, for example by evaporation under reduced pressure, and further purified, if desired, by standard methods such as chromatography, crystallization, or distillation. Scheme 3 base R 6a HN-O— R 7, a The phenylamino benzoic acid next is reacted with a hydroxylamine derivative HNR6 a OR7 a in the presence of a peptide coupling reagent. Hydroxylamine derivatives that can be employed include methoxylamine, N-ethyl-isopropoxy amine, and tetrahydro-oxazine. Typical coupling reagents include 2-ethoxy-l-ethoxycarbonyl-l,2-dihydroquinoline (EEDQ), 1 ,3-dicyclohexylcarbodiimide (DCC), bromo-tris(pyrrolidino)-phosphonium hexafluorophosphate (PyBrOP) and (benzotriazolyloxy)tripyrrolidino phosphonium hexafluorophosphate (PyBOP). The phenylamino benzoic acid and hydroxylamino derivative normally are mixed in approximately equimolar quantities in an unreactive organic solvent such as dichloromethane, tetrahydrofuran, chloroform, or xylene, and an equimolar quantity of the coupling reagent is added. A base such as triethylamine or diisopropylethylamine can be added to act as an acid scavenger if desired. The coupling reaction generally is complete after about 10 minutes to 2 hours, and the product is readily isolated by removing the reaction solvent, for instance by evaporation under reduced pressure, and purifying the product by standard methods such as chromatography or crystallizations from solvents such as acetone, diethyl ether, or ethanol. An alternative method for making the invention compounds involves first converting a benzoic acid to a hydroxamic acid derivative, and then reacting the hydroxamic acid derivative with an aniline. This synthetic sequence is depicted in Scheme 4, where L is a leaving group. The general reaction conditions for both of the steps in Scheme 4 are the same as those described above for Scheme 3. Scheme 4 Yet another method for making invention compounds comprises reacting a phenylamino benzhydroxamic acid with an ester forming group as depicted in Scheme 5, where L is a leaving group such as halo, and a base is triethylamine or diisopropylamine. Scheme 5 base The synthesis of compounds of Formula (II) is further illustrated by the following detailed examples.

of antigen-induced interleukin-5 (IL-5) production in vitro, (2) inhibition of the passive-transfer of eosinophilic lung inflammation in vivo, and (3) inhibition of active eosinophilic lung inflammation in vivo. For each of these assays, female C57BL/6 mice obtained from the Jackson Laboratory (Bar Harbor, ME) were given an intraperitoneal (i.p.) injection of ovalbumin (OVA, Grade V, Sigma Chemical Company, St. Louis, MO) adsorbed to aluminum hydroxide (10 μg ON A + 9 mg aluminum hydroxide in 200 μL saline). This sensitizes OVA-specific lymphocytes for subsequent restimulation either in vivo or in vitro. The first set of experiments was designed to determine whether the MEK inhibitors could prevent antigen-induced production of IL-5 by the ONA-primed splenocytes in vitro. IL-5 is required for the differentiation, migration, and survival of pulmonary eosinophils, which are thought to be responsible for much of the pathology associated with human asthma. In order to examine the effects of MEK inhibitors on IL-5 production, ONA-sensitized mice were sacrificed by cervical dislocation 14 days after sensitization (Day 14), the spleens were excised and disaggregated, and the erythrocytes were lysed. The splenocytes were washed and resuspended at 5 x 10 > cells/mL in complete medium consisting of RPMI 1640 (Gibco BRL, Gaithersburg, MD) with 10% heat-inactivated fetal calf serum (Hyclone, Logan, UT), 55 μM 2-mercaptoethanol, 50 U/mL penicillin G, 50 μg/mL streptomycin sulfate, and 2 mM L-glutamine (Gibco BRL). The splenocytes were then cultured at 37°C in the presence of 200 μg/mL ON A. MEK inhibitors were also added to the cultures from sterile 10 mM stock solutions (in DMSO). After 3 days, the culture medium was recovered and assayed for IL-5 by specific ELISA. The results of the analysis of IL-5 inhibition are presented in Table 1. All MEK inhibitors tested were found to potently inhibit antigen-induced IL-5 production. Table 1. The Effects of MEK Inhibitors on Antigen- Induced IL-5 Production MEK Inhibitor IC50 (nM) PD 184386 23 PD 171984 117 PD 170611 1,121 PD 184161 1,147 PD 177168 1,205 PD 184352 1,622 PD 098059 17,440 When OVA-sensitized spleen cells are restimulated with OVA in vitro for 3 days, as described above, the spleen cells not only produce IL-5, but also acquire the ability to induce eosinophilic lung inflammation when transfened into naϊve recipient mice. The critical cell type responsible for this adoptively- transferred activity is thought to be IL-5 -producing T lymphocytes. Because the results of the first set of experiments indicated that the MEK inhibitors inhibited IL-5 production by cultured splenocytes, a second set of experiments was initiated to determine whether the MEK inhibitor-treated cells were capable of transferring eosinophilic lung inflammation to naϊve mice. Splenocytes from OVA restimulation cultures, with or without the addition of MEK inhibitors were harvested after 3 days of culture, washed three times, and resuspended at 1 x 10 > cells/mL in sterile saline. Groups of five naϊve (unsensitized) C57BL/c mice were injected i.p. with 200 μL of the cell suspension (2 x 10^ cells). Three days after transfer of cells, the recipient mice were challenged with a 12-minute inhalation of an aerosol formulation of 1.5% OVA in saline (weight/volume), the mist being produced by a nebulizer (small particle generator model SPAG-2, ICN Pharmaceuticals, Costa Mesa, CA). Three days after aerosol challenge, the mice were anesthetized with an i.p. injection of an anesthetic mixture comprising Ketamine, acepromazine, and xylazine. The trachea of each mouse was exposed and cannulated. The lungs and upper airways were lavaged with 0.5 mL of cold (5°C) phosphate buffered saline (PBS). The cells within a 200 μL portion of the bronchoalveolar lavage (BAL) fluid were enumerated using a Coulter counter (Model ZB 1, Coulter Electronics, Hialeah, FL). The remaining BAL fluid was then centrifuged at 300 x g for 5 minutes, and the cells resuspended in 1 mL of Hank's balanced salt solution (HBSS, Gibco BRL), containing 0.5% fetal calf serum, and 10 mM of N-2-hydroxyethylpiperazine-N-2-ethanesulfonic acid (HEPES, Gibco BRL). The cell suspension (100 μL) was centrifuged in a cytospin (Shandon Southern Instruments, Sewickley, PA) and stained with Diff Quick to distinguish neutrophil, eosinophil, monocyte, and lymphocyte subsets. The number of eosinophils in the BAL fluid was determined by multiplying the percentage of eosinophils by the total cell count. As shown in Table 2, OVA-sensitized splenocytes cultured in the absence of MEK inhibitor, when transfened to naϊve recipient mice, were able to promote eosinophilic lung inflammation in response to an aerosol challenge with OVA. In contrast, splenocytes cultured in the presence of the MEK inhibitors PD 171984, PD 184352, and PD 184386 (10 μM each) did not promote eosinophilic lung inflammation (>99% inhibition). For each of the MEK inhibitors used, a 10 μM concentration was previously found to inhibit IL-5 production by over 75% (Table 1). These results suggest that the MEK inhibitors inhibit the IL-5-producing T lymphocytes that are required to support asthma-like eosinophilic lung inflammation in mice. Table 2.

Mice were sensitized with OV A/aluminum hydroxide on Day 0 as described above. On Day 14, the mice were challenged by aerosol with 1.5% OVA, as described above for the adoptive-transfer recipients. One group of eight sensitized mice was dosed orally with vehicle (0.5% hydroxypropylmethylcellulose/0.25% TWEEN-80). Other groups of sensitized mice (8 mice per group) were given oral doses of a MEK inhibitor. The test compound was dissolved in the vehicle, and the volume for each dosage was adjusted to 200 μL, so that each test animal received the same oral volume. In experiments reported in Table 3 and Table 4, the MEK inhibitor was administered starting on Day 13 (ie, 13 days after initial sensitization and 1 day prior to aerosol challenge), and continued daily through Day 16 (4 days total). In experiments reported in Table 5, the MEK inhibitor was administered starting on Day 7 (ie, 7 days after initial sensitization and 7 days prior to aerosol challenge), and continued daily through Day 16 (9 days total). On Day 17 of each experiment (17 days following the initial OVA challenge, and 3 days after the OVA aerosol challenge), all animals including controls were anesthetized, cannulated, and lavaged as previously described. The number of BAL eosinophils was determined as described above. In the initial analysis of active OVA-induced lung inflammation, multiple MEK inhibitors (PD 171984, PD 177168, PD 184161, PD 184386, and PD 184352) were dosed orally for 4 days. Only one compound, PD 171984, demonstrated any inhibition of pulmonary eosinophilia (Table 3). PD 171984, along with PD 184352, were tested again at multiple doses, again dosing for only 4 days. The results in Table 4 essentially parallel those in Table 3 for these compounds; PD 171984 appears active, whereas PD 184352 does not. As reported in Table 5, increasing the oral dosing schedule from 4 days to 9 days (7 days prior to aerosol challenge, 2 days after) resulted in a degree of inhibitory activity for PD 184352 at 100 mg/kg (59.85% inhibition, p = 0.11). PD 171984 continued to demonstrate statistically significant inhibitory activity under this dosing regimen. In total, these results indicate that MEK inhibitors, when used in vitro, are potent inhibitors of IL-5 production, and completely inhibit the ability of antigen- stimulated cells to adoptively transfer asthma-like symptoms to naϊve recipient mice. When used in vivo, some MEK inhibitors are more active than others. However, a less potent compound (PD 184352) was shown to inhibit the asthmalike response in mice under a more rigorous dosing regimen. Thus, the foregoing data establish that the selective MEK inhibitors are active in inhibiting a model of asthma in mice. The compounds have little or no toxic effects, and accordingly are particularly well-suited for treating and controlling asthma in children, as well as adults. The compounds will be formulated for convenient oral or parenteral administration, including by aerosol delivery, transdermal delivery, or even suppositories, and will be administered in an antiasthmatic effective dose, which is that amount that is effective to treat the particular asthma severity for which treatment is needed or otherwise desired.
