Description

PHENYL ACETIC ACIDS SUBSTITUTED AS DP-2 ANTAGONISTS BACKGROUND OF THE INVENTION Prostaglandin D2 (PGD2) is the main pro-inflammatory mediator abundantly secreted by activated mast cells through the allergenic exposure of a previously sensitized host. PGD2 is able to produce a multitude of pathobiological responses relevant to inflammatory disorders including airway constriction, leukocyte influx, increased vascular permeability, edema and mucosal secretion. The biological actions of PGD2 are mediated by at least 3 different receptors coupled to the G protein: the high affinity receptors DP-1 (formerly known as DP) and DP-2 (formerly known as the orphan receptor "protein receptor"). G "GPR44 and" the homologous chemoattractant receptor expressed on Th2 cells ", CRTH2 (See Hirai, H. et al., 'J. Exp. Med., 2001, 193 (2): 255-61; Nagata, KJ Biol. Regul. Homeost, Agents 2003, 17 (4): 334-7) and the A2 receptor of thromboxane, TP, to which PGD2 binds with low affinity.The DP-2 receptor is a major contributor to the pathophysiological actions of PGD2 Therefore, it is likely that pharmacists who target this receptor are therapeutically beneficial to a host of disorders, specifically inflammatory conditions that they have an allergic component, such as asthma (See Huang, J., J. Microbiol, Immunol, Infect., 2005, 38 (3): 158-63). DP-2 is selectively expressed in eosinophils, basophils and highly polarized Th2 cells in humans. These cell types are well known contributors to inflammatory disorders and other conditions. Activation of DP-2, a chemoattractant receptor, stimulates the chemotaxis of human Th2 cells, eosinophils and basophils both in vitro and in vivo, and may mediate recruitment of relevant cell types in diseased sites and exacerbate ultimate organ damage . DP-2 agonists are capable of directly activating inflammatory cells and activation mediated by DP-2 and release of the eosinophil and basophil mediator has been reported (see Gervais FG, et al., J. Allergy Clin. Immunol ., (2004), 108 (6): 982-8, Yoshimura-Uchiyama, C, et al., Clin. Exp. Allergy 2004, 34 (8): 1283-90). In addition, Th2 effector T lymphocytes will elaborate the inflammatory cytosines IL-4, IL-5 and IL-13 in response to the stimulation of DP-2 (See Xue, L., et al., J. Immunol., 2005, 175 (10): 6531-6). These cytosines, in turn, act as important regulators of inflammatory responses and support Th2 cell differentiation, mast cell growth, differentiation and synthesis of IgE, and differentiation, infiltration and survival of eosinophils. This suggests that the PGD2 / DP-2 pathway acts as a positive feeding circuit and increases pathological responses in disorders associated with excessive or unregulated production of PGD2. Consequently, pharmaceutical agents that interfere with this trajectory may have utility in the treatment of a wide range of allergic and inflammatory conditions and other disorders. The utility of PGD2 antagonists in the treatment of inflammatory disorders is supported by clinical studies with Ramatroban® (Baynas, BAY u3405). Clinical studies have shown a beneficial effect of Ramatroban® on rhinitis symptoms as well as on inflammatory markers in nasal washes, suggesting an anti-inflammatory activity. Ramatroban® was initially described as a selective TP antagonist, and it is believed that its clinical effects in rhinitis are mediated by TP. However, recent discoveries revealed that Ramatroban® possesses a double specificity and antagonizes both TP and DP-2 receptors (See Sugimoto, H., et al., J. Pharmacol. Exp. Ther., 2003, 305 (1 ): 347-52). In light of the presence of DP-2 in the pivotal inflammatory cells involved in allergic rhinitis and the stimulatory effects of PGD2 and other DP-2 agonists in these cells, it is reasonable to postulate that The clinical benefits of Ramatroban® in allergic rhinitis are long-term due to its activity against the DP-2 receptor. Accordingly, it can be inferred that selective DP-2 antagonists may be useful in the treatment of allergic rhinitis, other inflammatory conditions, other conditions where the PGD2 pathway is not regulated, as well as other disorders where it has been established the utility of Ramatroban®. Minami et al., Have demonstrated the effectiveness of Ramatroban® in edema in experimental allergic conjunctivitis (See Minami, K., et al., Int. Immunopharmacol., 2004, 4 (12): 1531-5). It has been shown that DP-2 exerts an essential role in allergic disorders, specifically, in IgE-mediated skin responses that occur in chronic contact hypersensitivity (See Mitsumori S., Curr. Pharm. Des. 2004, 10 (28). ): 3533 -8); Moroi R., et al., 30th Annu. Meet. Jpn. Soc. Invest. Dermatol. (April 20 -April 22, Yokohama) 2005, Abst. 48). Numerous compounds have been reported as modulators of PGD2 receptors and / or useful for the treatment of allergic and inflammatory disorders.

No 2004132772 describes a series of compounds of tetrahydroquinoline as DP-2 antagonists that are said to be useful for the treatment of allergic asthma and allergic rhinitis. O 2003066046, O 2003066047, WO 2003101961, WO 2003101981 and WO 2004007451 describe a series of indole acetic acids which are said to be useful in the treatment of asthma, chronic obstructive pulmonary disease (COPD), rhinitis and other conditions. WO2003097598 describes a series of compounds that are said to exhibit antagonism to the PGD2 receptor.

EP 1170594 describes methods for the identification of compounds useful for the treatment of conditions mediated by prostaglandin D2, a ligand for the orphan receptor DP-2. GB 1356834 describes a series of compounds that are said to possess anti-inflammatory, analgesic and antipyretic activity. Even so, there is a relative shortage in the drug market that selectively modulates bound non-aminergic receptors coupled to the G protein (see Beaumont K., et al., Bioorg, Med. Chem. Lett., 2005, 15 (16 ): 3658-64). SUMMARY OF THE INVENTION It has surprisingly been discovered that certain phenyl acetic acids are potent DP-2 receptor antagonists.

Examples of alkenyl groups include vinyl, 2-propenyl, crotyl, 2-isopentenyl, 2- (butadienyl), 2,4-pentadienyl, 3- (1,4-pentadienyl) and higher homologs and isomers thereof. The term "alkynyl", by itself or as part of another substituent, means a hydrocarbon radical of straight or branched chain, or combinations thereof, which may be mono or polyunsaturated, which has the number of carbon atoms designated (i.e., C2-C8 means two to eight carbons) and one or more triple bonds. Examples of alkynyl groups include ethynyl, 1 and 3-propynyl, 3-butynyl and higher homologs and isomers thereof. The term "alkylene", by itself or as part of another substituent, means a bivalent radical derived from alkyl, as exemplified by -CH2CH2CH2CH2-. Typically, an alkyl (or alkylene) group will have from 1 to 24 carbon atoms, those groups having 10 or fewer preferred carbon atoms in the present invention. A "lower alkyl" or "lower alkylene" is a shorter chain alkyl or alkylene group, which generally has eight or fewer carbon atoms. The terms "alkoxy", "alkylamino" and "alkylthio" (or thioalkoxy) are used in their conventional sense, and refer to those alkyl groups attached to the rest of the molecule by an oxygen atom, an amino group, or a sulfur atom, respectively. Similarly, the term dialkylamino refers to an amino group having two attached alkyl groups which may be the same or different. The term "heteroalkyl", by itself or in combination with another term, means, unless define from another matera, a straight or branched or cyclic chain hydrocarbon radical, or combinations thereof, consisting of a defined number of carbon atoms and from one to three heteroatoms selected from 0, N, Si and S, and wherein the nitrogen and sulfur atoms may optionally be oxidized and the nitrogen heteroatom optionally quaternized. The heteroatom (s) 0, N and S may be placed in any interior position of the heteroalkyl group. The heteroatom Si can be placed at any position of the heteroalkyl group, including the position at which the alkyl group is attached to the rest of the molecule. Examples include -CH2-CH2-0-CH3f -CH2-CH2-H-CH3, -CH2-CH2-N (CH3) -CH3i -CH2-S-CH2-CH3 / -CH2-CH2 / -S (0) -CH3, -CH2-CH2-S (O) 2-CH3, -CH = CH-0-CH3, -Si (CH3) 3, -CH2-CH = N-OCH3 and -CH = CH-N (CH3) -CH3. Up to two heteroatoms can be consecutive, such as, for example, -CH2-NH-OCH3 and -CH2-0-Si (CH3) 3. When a prefix such as (C2-C8) is used to refer to a heteroalkyl group, the number of carbons (2-8 in this example) is also intended to include heteroatoms. For example, a C2 heteroalkyl group is intended to include, for example, -CH20H (a carbon atom and a heteroatom replacing a carbon atom) and -CH2SH. The term "heteroalkylene", by itself or as part of another substituent, means a bivalent radical derived from heteroalkyl, as exemplified by -CH2-CH2-S-CH2CH2- and -CH2-S-CH2-CH2-NH-CH2. For the heteroalkylene groups, the heteroatoms may also occupy either or both of the chain terminals (e.g., alkyleneoxy, alkylenedioxy, alkyleneamino, alkylenediamino and the like). Still further, for the alkylene and heteroalkylene linking groups, no orientation of the linking group is implied. The terms "cycloalkyl", "heterocyclyl" and "heterocyclic ring", by themselves or in combination with other terms, represent, unless otherwise defined, cyclic versions of "alkyl" and "heteroalkyl", respectively. Therefore, the terms "cycloalkyl" and "heterocyclic ring" are intended to be included in the terms "alkyl" and "heteroalkyl", respectively. Additionally, for a heterocyclic ring, the heteroatom can occupy the position in which the heterocycle is bound to the rest of the molecule. Examples of cycloalkyl include cyclopentyl, cyclohexyl, 1-cyclohexenyl, 3-cyclohexenyl, cyclopentyl and the like. Examples of a heterocyclic ring include pyrrolidinyl, pyrrolyl, piperadynyl, tetrahydropyridinyl, piperazinyl, piperazin-1-oxide, morpholinyl, thiomorpholinyl, azepanyl, azepinyl, oxazepan, thiazepam, azocanyl, azocinyl, indolyl, azaindole, tetrahydroquinolinyl, decahydroquinolinyl, tetrahydrobenzooxazepinyl, dihydrodibenzooxepin and the like. The terms "halo" or "halogen", by themselves or as part of another substituent, mean, unless otherwise defined, a fluorine, chlorine, bromine or iodine atom. Additionally, terms such as "haloalkyl", are intended to include alkyl substituted with halogen atoms, which may be the same or different, in a number ranging from one to (2m '+ 1), where m' is the total number of carbon atoms in the alkyl group. For example, the term "haloalkyl Cl-6" is intended to include trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl, 3-bromopropyl and the like. Thus, the term "haloalkyl" includes monohaloalkyl (alkyl substituted with a halogen atom) and polyhaloalkyl (alkyl substituted with halogen atoms in a number ranging from two to (2m '+ 1) halogen atoms). The term "perhaloalkyl" means, unless otherwise defined, alkyl substituted with (2m '+ 1) halogen atoms, where m' is the total number of carbon atoms in the alkyl group. For example, the term perhaloalkyl C! -6", is intended to include trifluoromethyl, pentachloroethyl, 1,1,1-trifluoro-2-bromo-2-chloroethyl and the like.The term" aryl "means, unless defined by another way, a typically aromatic polyunsaturated hydrocarbon substituent which may be of a single ring or multiple rings (up to three rings) which is they merge with each other or they are linked covalently. The term "heteroaryl" refers to aryl groups (or rings) containing one to four heteroatoms selected from the group consisting of N, 0 and S, wherein the nitrogen and sulfur atoms are optionally oxidized, and the ) Nitrogen atom (s) is optionally quaternized (s).

For brevity, the term "aryl" when used in combination with other terms (e.g., aryloxy, arylthioxy, arylalkyl), includes both aryl and heteroaryl rings as defined above. Thus, the term "arylalkyl" is intended to include those radicals in which an aryl group is attached to an alkyl group (eg, benzyl, phenethyl, pyridylmethyl, and the like) including those alkyl groups in which a carbon atom (eg. , a methylene group) has been replaced, for example, by an oxygen atom (eg, phenoxymethyl, 2-pyridyloxymethyl, 3- (1-naphthyloxy) propyl and the like). Each of the foregoing terms (e.g., "alkyl", "heteroalkyl", "aryl" and "heteroaryl") is intended to include both substituted and unsubstituted forms of the indicated radical, unless otherwise indicated. Preferred substituents for each type of radical are given below. The substituents for the alkyl and heteroalkyl (as well as those groups referred to as alkylene, alkenyl, heteroalkylene, heteroalkenyl, alkynyl, cycloalkyl, heterocyclyl) can be a variety of groups selected from: -OR ', = 0, = NR', = N-OR ', -NR 'R', -SR ', halogen, -SiR'R "R'", -0C (0) R ', C (0) R ', -C02R', -CONR'R ", -0C (0) NR'R", - R "C (0) R ', -NR' -C (0) NR '' R ' '', -NR '-S02- R "R"', -NR "C02R ', -NH-C (NH2) = NH, -NR'C (NH2) = NH, -NH-C (NH2) = NR ', -S (0) R', -S02R ', -SONR'R'. -NR''S02R, -CN and -N02, in a number that fluctuates from zero to three, being those groups that have zero, one or two particularly preferred substituents R ', R "and R" "each independently refer to hydrogen, unsubstituted Ci-6alkyl and heteroalkyl, unsubstituted aryl, aryl substituted with one to three halogens, unsubstituted alkyl , alkoxy or trioalkoxy groups, or aryl-Ci_6alkyl groups When R 'and R "are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 5, 6 or 7 membered ring. , -NR'R "is intended to include 1-pyrrolidinyl and 4-morpholinyl Typically, an alkyl or heteroalkyl group will have from zero to three substituents, those groups having two or less substituents being preferred in the present invention.

In addition to the salt forms, the invention provides compounds that are in prodrug form. The prodrugs of the compounds described herein are compounds that readily undergo chemical changes under physiological conditions to provide the compounds of the formula I which are DP-2 receptor antagonists. Additionally, prodrugs can be converted to the compounds of the invention by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to the compounds of the invention, when placed in a transdermal patch reservoir with an enzyme or suitable chemical reagent. Prodrugs are often useful because, in some situations, they may be easier to administer than the original drug. For example, they can be bioavailable by oral administration while the drug of origin does not. The prodrug may also have an improved solubility in the pharmaceutical compositions on the original drug. A wide variety of prodrug derivatives are known in the art, such as those based on hydrolytic cleavage or oxidative activation of the prodrug. An example, without limitation, of a prodrug would be a compound of the invention that is administered as an ester (eg, wherein R1 is substituted or unsubstituted Ci_6 alkyl, C0.6 alkylaryl or C0.e alkylheteroaryl, "prodrug") , but then, metabolically hydrolyzed to the carboxylic acid (e.g., where R1 is H, the "active entity"). Additional examples include peptidyl derivatives of a compound of the invention. Certain compounds of the invention can exist in undissolved forms as well as in dissolved forms, including hydrated forms. In general, the dissolved forms are equivalent to the undissolved forms and are intended to be encompassed within the scope of the invention. Certain compounds of the invention can exist in multiple crystalline or amorphous forms. In general, all physical forms are equivalent for the uses contemplated by the invention and are intended to be within the scope of the invention. Certain compounds of the invention possess asymmetric carbon atoms (optical centers) or double bonds; the racemates, enantiomers, diastereomers, geometric isomers and individual isomers are all intended to be encompassed within the scope of the invention. These isomers can be dissolved or synthesized asymmetrically using conventional methods to make the isomers "optically pure", i.e., substantially free of their other isomers. If, for example, a particular enantiomer of a compound of the present invention is desired, it can be prepared by asymmetric synthesis or by derivatization with a chiral auxiliary, where the prepared diastereomeric mixture is separated and the auxiliary group is divided to provide the desired pure enantiomers. Alternatively, when the molecule contains a basic functional group, such as amino or an acidic functional group, such as carboxyl, diastereomeric salts are formed with an appropriate optically active acid or base, followed by resolution of the diastereomers thus formed by crystallization media. fractional or chromatographic well known in the art and the subsequent recovery of the pure enantiomers. The compounds of the invention may also contain unnatural proportions of atomic isotopes in one or more of the atoms that make up such compounds. For example, the compounds can be radiolabeled with radioactive isotopes, such as, for example, tritium (3H), iodine-125 (125I) or carbon-14 (14C). Radiolabeled compounds are useful as therapeutic or prophylactic agents, e.g., cancer therapeutic agents, research reagents, e.g., reagents for DP-2 analysis and diagnostic agents, e.g., in vivo visualization agents. All isotopic variations of the compounds of the invention, whether radioactive or not, are intended to be encompassed within the scope of the invention.

The phrase "selectively" or "specifically" when referring to the link to a receptor, refers to a binding reaction determining the presence of the receptor, frequently in a homogeneous population of receptors and other biological ones. Thus, under the designated conditions, the compounds bind to a particular receptor at least twice the background and more typically at more than 10 to 100 times the background. The specific binding of a compound under such conditions requires a compound selected for its specificity for a particular receptor. For example, small organic molecules can be screened to obtain only those compounds which bind specifically or selectively to a selected receptor and not to other receptors or proteins. A variety of analysis formats can be used to select compounds that are selective for a particular receptor. For example, high throughput screening analyzes are routinely used to select compounds that are selective for a particular receptor.

Inappropriate functional activity of a PGD2 receptor may arise as a result of the expression of a PGD2 receptor in cells that do not normally express the receptor, a higher than normal production of PGD2, or a slower or slower inactivation or metabolic clearance than normal of PGD2 or its active metabolites, an increased expression of a PGD2 receptor or the degree of intracellular activation (leading, eg, to disorders and inflammatory conditions and related to immunity) or a decreased expression of a PGD2 receptor. A condition or disorder associated with a PGD2 receptor may include a "condition or disorder mediated by DP-2." As used herein, the phrases "condition or disorder that responds to the antagonism of a DP-2 receptor" and related phrases and terms, refers to a condition or disorder characterized by an inappropriate activity, eg, greater than the normal, of DP-2. Inappropriate functional activity of DP-2 may arise as a result of the expression of DP-2 in cells that do not normally express DP-2 or an increased expression of DP-2 or an intracellular activation degree (leading to, e.g., disorders and inflammatory conditions and related to immunity). A condition or disorder that responds to the antagonism of a DP-2 receptor may be completely or partially mediated by an inappropriate DP-2 functional activity. However, a condition or disorder that responds to the antagonism of a DP-2 receptor is one in which modulation of DP-2 results in some effect on the underlying condition or disorder (eg, a DP-2 antagonist). results in some improvement in the patient's well-being at least in some patients).

Analysis of the Compounds In yet another aspect, the invention includes methods for evaluating putative agonists or antagonists specific to DP-2 and / or one or more different PGD2 receptors. Accordingly, the invention is directed to the use of these compounds in the preparation and execution of analysis of detection for compounds that modulate the function of DP-2 and / or one or more different PGD2 receptors. For example, the compounds of this invention are useful for mutants of DP-2 and / or one or more mutants of the different PGD2 receptors, which are excellent detection tools for potent compounds. In addition, the compounds of this invention are useful for establishing or determining the binding site of other compounds to DP-2 and / or one or more different PGD2 receptors, e.g., by competitive inhibition. The compounds of the present invention are also useful for the evaluation of putative modulators specific for DP-2 and / or on one or more different PGD2 receptors. The person skilled in the art will appreciate that the complete evaluation of specific antagonists of PGD2 receptors has been obstructed by the lack of availability of specific non-peptidyl (metabolically resistant) compounds with high binding affinity for these receptors. The compounds provided herein are particularly useful in this context. The above and other analyzes described herein are designed to be compliant to a high performance format for detecting or quantifying the presence, absence, quantification, or other properties of particular compounds, individually or as a library containing a large number of compounds Potential Therapeutics (potential modulator compounds). Any of the steps of the analysis can be automated and compounds can be provided to the analysis from any convenient source. Analyzes are typically operated in parallel (e.g., in microtiter plate formats in robotic analyzes). Preferred assays detect the enhancement or inhibition of DP-2, the function of DP-2 and / or one or more different PGD2 receptors. High performance detection systems are commercially available (see e.g., Zymark Corp. Hopkinton Mass.; Air Technical Industries, Mentor Ohio; Beckman Instruments, Inc., Fullerton Calif .; Precision Systems Inc., Natick Mass .; etc.). These systems typically automate complete procedures, including pipetting of all sample and reagent, fluid supply, timed incubations and final microplate readings in the appropriate detector (s) for analysis. These configurable systems provide high performance and fast start-up as well as a high degree of flexibility and suitability. The manufacturers of such systems provide detailed protocols for several high performance systems. Therefore, for example, Zymark Corp. provides technical bulletins describing detection systems to detect the modulation of gene transcription, ligand binding, and the like.

For aerosol delivery in humans or other primates and mammals, the aerosol is generated by a medical nebulizer system that delivers the aerosol through a buccal piece, face mask, etc., from which the mammalian host can introduce the aerosol to the lungs Various sprayers are known in the art and can be used in the method of the present invention. The selection of a nebulizer system depends on whether an alveolar or respiratory supply is desired (i.e., trachea, primary, secondary or tertiary bronchi, etc.). The composition is formulated so as not to be too irritating in the required dose. Nebulizers useful for airway delivery include those typically used in the treatment of asthma. Such nebulizers are also commercially available. a therapeutic amount of the agent is an amount sufficient to prevent, treat or alleviate asthma after administration of the composition to the lung of the mammalian host, particularly the alveoli or bronchopulmonary way and the soft muscle in a bronchiolopulmonary fashion and to the epithelial cells of the trachea, bronchi, bronchioles, and alveoli. Therefore, an effective amount of the aerosol compound of the invention is a sufficient dose to effect the treatment, that is, to cause the relief or reduction of the symptoms, to inhibit the worsening of the symptoms, to prevent the onset of the symptoms and the like. The doses of the present compositions that constitute an effective amount, can be determined in view of this description by the one of ordinary experience in the technique, carrying out routine tests with appropriate controls. Comparison of appropriate treatment groups with controls will indicate whether a particular dose is effective in preventing or reducing particular symptoms. The total amount of a compound delivered to a mammalian host will depend on many factors, including the total amount aerosolized, the type of nebulizer, the particle size, the respiration patterns of the mammalian host, the severity of the lung disease, the concentration of the composition of the compound in the aerosolized solution and the extension of the inhalation therapy. In spite of the interacting factors described above, one of ordinary skill in the art will be able to easily design effective protocols, particularly if the aerosol particle size is optimized. Based on estimates of the efficiency of the nebulizer, an effective dose delivered commonly falls in the range of about 1 mg / treatment to about 500 mg / treatment, although it may be more or less effective depending on the subject, the agent, the dose regimen , and the desired result. Generally, it is desirable to administer higher doses when treating more severe conditions. If the treatment is repeated, the mammalian host can be monitored to ensure that no There is an adverse response to treatment. The frequency of treatments depends on a number of factors, such as the amount of the agent administered per dose as well as the health and history of the subject.

Asthma Diagnosis Methods for diagnosing asthma and other disorders or inflammatory and obstructive inflammatory conditions are well known to those of ordinary skill in the art. For example, spirometry may be used to evaluate lung function. The diagnosis of asthma, in particular, may be made, in part, on the basis of family history or personal history of a severe and sudden episode or recurrent episodes of wheezing, coughing or shortness of breath that may be associated with exposure to an allergen. or exacerbated or precipitated by moderate exercise. Typically a physical examination is involved to detect the disorder or condition. Using a nasal speculum, the nose can be examined for signs of disorder or allergic condition such as increased nasal secretions, swelling, or polyps that can trigger asthma. A stethoscope can be used to listen to the sounds produced by the lungs during breathing. Whistling sounds are one of the main indicators of obstructed airways associated with asthma. In addition allergic conditions such as eczema or hives, are frequently associated with asthma. Pulmonary function tests are particularly useful in confirming the diagnosis of disorders or respiratory conditions. These tests include spirometry to determine vital capacity, the maximum amount of air that can be inhaled and exhaled; the peak expiratory flow rate, also known as the peak flow rate, which is the maximum flow rate that can be generated during a forced exhalation; and forced expiratory volume, which is the maximum amount of air that can be exhaled in a second. If the measurements are below normal for a person of their age, a bronchodilator drug used in the treatment of asthma can be given to open the clogged air passages and repeat spirometry. If the measurements increase significantly, it is the probability of asthma. In addition, asthma can be diagnosed by testing the individual with exercise or by inhaling a chemical constrictor. the airways or taking several breaths of cold air. After testing with a substance or activity that produces the symptom, the spirometry test is re-administered. If spirometry measurements fall significantly, asthma is indicated. The following examples are offered by way of illustration and are not intended to limit the scope of the invention. Those skilled in the art will readily recognize a variety of non-critical parameters that could be modified to produce essentially similar results. EXAMPLES General Methods: The invention will now be illustrated by the following non-limiting examples. The title and sub-title compounds of the examples and methods were named using ChemDraw Ultra (version 7.0) from Cambridge Soft Inc. Flash column chromatography refers to normal phase silica chromatography. The reagents and solvents used can be obtained from commercial sources such as Aldrich Chemical Co. (Milwaukee, Wis., USA). The solvents were dried with MgSO4 or Na2SO4. The evaporations were carried out by rotary evaporation in vacuo and the production processes were carried out after removal of the residual solids such as drying agents, by filtration. Unless defined otherwise, the operations were carried out at room temperature, that is, in the range of 18-25 ° C and under an atmosphere of an inert gas such as argon or nitrogen. The returns are provided for illustration only and are not necessarily the maximum obtainable. The structures of the final products of the structure (I) were confirmed by nuclear magnetic resonance (usually protons) (PMR) and mass spectral techniques.
