Description

The present invention relates to compounds of formula I, a process for their production and their use as anti-inflammatory agents.


From the prior art of DE 100 38 639 and WO 02/10143, anti-inflammatory agents of the following general formula







are known, in which the Ar radical comprises phthalides, thiophthalides, benzoxazinones or phthalazinones. In the experiment, these compounds show dissociations of action between anti-inflammatory and undesirable metabolic actions and are superior to the previously described nonsteroidal glucocorticoids or exhibit at least just as good an action. Nevertheless these compounds possess a linear structure as also the compounds disclosed in WO2006/108699, and WO2007/000334 whereas the compounds disclosed in the following publications do have a bicyclic ring moiety:


WO2005/034939, WO2006/100100, WO2006/108712.

However, the selectivity of the compounds of the prior art towards the glucocorticoid receptor (GR) compared to the other steroid receptors still requires improvement. Also dissociation between wanted anti inflammatory effects and unwanted metabolic side effects requires improvement.


It was therefore the object of this invention to make compounds available whose selectivity towards the glucocorticoid receptor (GR) is improved compared to the other steroid receptors and which show a better dissociation regarding potential side effects or at least the same level of effect.


This object is achieved by the compounds according to the claims.


This invention therefore relates to a compound of general formula I







in which


X is N or C—R4


Y is N or C—R4

  • R1, R2, R3 independently of one another, are selected from the group consisting of hydrogen, halogen, cyano, nitro, hydroxy, or (C1—C5)-alkyl, (C1—C5)-halo-alkyl, (C1—C5)alkoxy, (C1—C5)halo-alkoxy and COOR9,

An aspect of the invention are compounds of formula I wherein the residues have the meaning of the residues as disclosed in the examples and all subcombinations thereof.


A preferred aspect of the invention are the compounds according to the examples.


In addition, the invention relates to the use of the compounds of general formula I for the production of pharmaceutical agents as well as their use for the production of pharmaceutical agents for treating inflammatory diseases.


The C1—C5-alkyl groups can be straight-chain or branched and stand for a methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, tert-butyl or n-pentyl group, or a 2,2-dimethylpropyl, 2-methylbutyl or 3-methylbutyl group. A methyl or ethyl group is preferred. They can optionally be substituted by 1-3 hydroxy, 1-3 C1—C5-alkoxy and/or 1-3 COOR6 groups. Preferred are hydroxy groups.


The C1—C5-alkoxy groups can be straight-chain or branched and stand for a methoxy, ethoxy, n-propoxy, iso-propoxy, n-butoxy, iso-butoxy, tert-butoxy or n-pentoxy, 2,2-dimethylpropoxy, 2-methylbutoxy or 3-methylbutoxy group. A methoxy or ethoxy group is preferred.


The designation halogen atom or halogen means a fluorine, chlorine, bromine or iodine atom. Preferred is a fluorine, chlorine or bromine atom. More preferred is a fluorine or chlorine atom. Most preferred is a fluorine atom.


Due to the presence of asymmetry centers, the compounds according to the invention of the general formula I occur as stereoisomers. All possible enantiomers, and if several asymmetric centres are present all possible diastereomers (e.g.: RR, RS, SR, SS), both in enantiomerically pure form and also as racemates, both as pure diastereomers and also as diastereomer mixtures, are objects of the present invention.


Prodrugs are defined as compounds that are cleaved into the compounds that are claimed by metabolism in the organism or by contact with the organism. The prodrugs are subject to at least one biotransformatory step until the claimed compounds are released, which then exert their pharmacological effect. Prodrugs of the presently claimed compounds are also an aspect of the invention. Examples of prodrugs are esters and amides built wherever chemically possible due to the individual residues at a specific compound of formula I as claimed.


The compounds according to the invention can also be present in the form of salts with physiologically compatible anions, for example in the form of hydrochlorides, sulfates, nitrates, phosphates, pivalates, maleates, fumarates, tartrates, benzoates, mesylates, citrates or succinates.


The process for the production of the compounds and intermediates of WO2005/034939, WO2006/027236, WO2006/066950, WO2006/100100, WO2006/108712, WO2006/108699 and WO2007/000334 can also be used for the production of the compounds and intermediates according to the invention.


An amino tetrahydronaphthaline of general formula (II), in which , R1 , R2, R3, R6, R7 and R8 have the meanings that are indicated for formula (I), is coupled with an acid of the general formula (III), in which under X, Y, R4 and R5 have the meaning that is indicated for formula (I), under usage of amide coupling reagents known to the expert like HATU (2-(1H-7-Azabezotriazol-1-yl)-1,1,3,3-tetramethyl uroniumhexafluoro-phosphate Methamminium), TBTU (O-(Benzotriazol-1-yl)-N, N, N′, N′,-tetramethyluronium tetrafluoroborate) or HBTU (2-(1H-Benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate Isomer I or 2-(1H-Benzotriazole-1-yl)-1,1,3,3-tetramethylguanidinium hexafluorophosphate Isomer II, or others from e.g. Larry Yet; “Peptide Coupling Reagents: Names, Acronyms and References”; Albany Molecular Research, Inc., Technical Reports, vol., 4, No. 1, pp. 1999; pp. 1-7) or via formation of the acid chloride to compounds of the general formula (I) according to the invention.







If the compounds according to the invention are present as racemic mixtures, they can be separated into pure, optically active forms according to the methods of racemate separation that are familiar to one skilled in the art. For example, the racemic mixtures can be separated by chromatography on an even optically active carrier material (CHIRALPAK AD®) into the pure isomers. It is also possible to esterify the free hydroxy group in a racemic compound of general formula I with an optically active acid and to separate the diastereoisomeric esters that are obtained by fractionated crystallization or by chromatography, and to saponify the separated esters in each case to the optically pure isomers. As an optically active acid, for example, mandelic acid, camphorsulfonic acid or tartaric acid can be used.


The binding of the substances to the glucocorticoid receptor (GR) and other steroid hormone receptors (mineral corticoid receptor (MR), progesterone receptor (PR) and androgen receptor (AR)) is examined with the aid of recombinantly produced receptors. Cytosol preparations of Sf9 cells, which had been infected with recombinant baculoviruses, which code for the GR, are used for the binding studies. In comparison to reference substance [3H]-dexamethasone, the substances show a high to very high affinity to GR. Example 3 thus shows, e.g., the following profile: IC50(GR)=6 nmol; IC50(MR), IC50(PR), IC50(AR), IC50(ER)>1 μmol.


As an essential, molecular mechanism for the anti-inflammatory action of glucocorticoids, the GR-mediated inhibition of the transcription of cytokines, adhesion molecules, enzymes and other pro-inflammatory factors is considered. This inhibition is produced by an interaction of the GR with other transcription factors, e.g., AP-1 and NF-kappa-B (for a survey, see Cato, A. C. B., and Wade, E., BioEssays 18, 371-378, 1996).


The compounds of general formula I according to the invention inhibit the secretion of cytokine IL-8 into the human monocyte cell line THP-1 that is triggered by lipopolysaccharide (LPS). The concentration of the cytokines was determined in the supernatant by means of commercially available ELISA kits. The compound of Example 3 showed an inhibition IC50(IL8)=7,1 nmol (96% eff. relative to dexamethasone).


The anti-inflammatory action of the compounds of general formula I was tested in the animal experiment by tests in the croton oil-induced inflammation in rats and mice (J. Exp. Med. (1995), 182, 99-108). To this end, croton oil in ethanolic solution was applied topically to the animals' ears. The test substances were also applied topically or systemically at the same time or two hours before the croton oil. After 16-24 hours, the ear weight was measured as a yardstick for inflammatory edema, the peroxidase activity as a yardstick for the invasions of granulocytes, and the elastase activity as a yardstick for the invasion of neutrophilic granulocytes. In this test, the compounds of general formula I inhibit the three above-mentioned inflammation parameters both after topical administration and after systemic administration.


One of the most frequent undesirable actions of a glucocorticoid therapy is the so-called “steroid diabetes” [cf., Hatz, H. J., Glucocorticoide: Immunologische Grundlagen, Pharmakologie und Therapierichtlinien [Glucocorticoids: Immunological Bases, Pharmacology and Therapy Guidelines], Wissenschaftliche Verlagsgesellschaft mbH, Stuttgart, 1998]. The reason for this is the stimulation of gluconeogenesis in the liver by induction of the enzymes responsible in this respect and by free amino acids, which are produced from the degradation of proteins (catabolic action of glucocorticoids). A key enzyme of the catabolic metabolism in the liver is tyrosinamino transferase (TAT). The activity of this enzyme can be determined from liver homogenates by photometry and represents a good measurement of the undesirable metabolic actions of glucocorticoids. To measure the TAT induction, the animals are sacrificed 8 hours after the test substances are administered, the livers are removed, and the TAT activity is measured in the homogenate. In this test, at doses in which they have an anti-inflammatory action, the compounds of general formula I induce little or no tyrosinamino transferase.


Because of their anti-inflammatory and, in addition, anti-allergic, immunosuppressive and antiproliferative action, the compounds of general formula I according to the invention can be used as medications for treatment or prophylaxis of the following pathologic conditions in mammals and humans: In this case, the term “DISEASE” stands for the following indications:

  • (i) Lung diseases, which coincide with inflammatory, allergic and/or proliferative processes:
    • Chronic, obstructive lung diseases of any origin, primarily bronchial asthma
    • Bronchitis of different origins
    • Adult respiratory distress syndrome (ARDS), acute respiratory distress syndrome
    • Bronchiectases
    • All forms of restrictive lung diseases, primarily allergic alveolitis,
    • All forms of pulmonary edema, primarily toxic pulmonary edema; e.g., radiogenic pneumonitis

Moreover, the compounds of general formula I according to the invention can be used for treatment and prophylaxis of additional pathologic conditions that are not mentioned above, for which synthetic glucocorticoids are now used (see in this respect Hatz, H. J., Glucocorticoide: Immunologische Grundlagen, Pharmakologie und Therapierichtlinien, Wissenschaftliche Verlagsgesellschaft mbH, Stuttgart, 1998).


All previously mentioned indications (i) to (xx) are described in more detail in Hatz, H. J., Glucocorticoide: Immunologische Grundlagen, Pharmakologie und Therapierichtlinien, Wissenschaftliche Verlagsgesellschaft mbH, Stuttgart, 1998.


For the therapeutic actions in the above-mentioned pathologic conditions, the suitable dose varies and depends on, for example, the active strength of the compound of general formula I, the host, the type of administration, and the type and severity of the conditions that are to be treated, as well as the use as a prophylactic agent or therapeutic agent.


In addition, the invention provides:


(i) The use of one of the compounds of formula I according to the invention or mixture thereof for the production of a medication for treating a DISEASE;


(ii) A process for treating a DISEASE, said process comprises an administration of an amount of the compound according to the invention, in which the amount suppresses the disease and in which the amount of compound is given to a patient who requires such a medication;


(iii) A pharmaceutical composition for treating a DISEASE, said treatment comprises one of the compounds according to the invention or mixture thereof and at least one pharmaceutical adjuvant and/or vehicle.


In general, satisfactory results can be expected in animals when the daily doses comprise a range of 1 μg to 100,000 μg of the compound according to the invention per kg of body weight. In the case of larger mammals, for example the human, a recommended daily dose lies in the range of 1 μg to 100,000 μg per kg of body weight. Preferred is a dose of 10 to 30,000 μg per kg of body weight, and more preferred is a dose of 10 to 10,000 μg per kg of body weight. For example, this dose is suitably administered several times daily. For treating acute shock (e.g., anaphylactic shock), individual doses can be given that are significantly above the above-mentioned doses.


The formulation of the pharmaceutical preparations based on the new compounds is carried out in a way that is known in the art by the active ingredient being processed with the vehicles that are commonly used in galenicals, fillers, substances that influence decomposition, binding agents, moisturizers, lubricants, absorbents, diluents, flavoring correctives, coloring agents, etc., and converted into the desired form of administration. In this case, reference is made to Remington's Pharmaceutical Science, 15th Edition, Mack Publishing Company, East Pennsylvania (1980).


For oral administration, especially tablets, coated tablets, capsules, pills, powders, granulates, lozenges, suspensions, emulsions or solutions are suitable.


For parenteral administration, injection and infusion preparations are possible.


For intra-articular injection, correspondingly prepared crystal suspensions can be used.


For intramuscular injection, aqueous and oily injection solutions or suspensions and corresponding depot preparations can be used.


For rectal administration, the new compounds can be used in the form of suppositories, capsules, solutions (e.g., in the form of enemas) and ointments both for systemic and for local treatment.


For pulmonary administration of the new compounds, the latter can be used in the form of aerosols and inhalants.


For local application to eyes, outer ear channels, middle ears, nasal cavities, and paranasal sinuses, the new compounds can be used as drops, ointments and tinctures in corresponding pharmaceutical preparations.


For topical application, formulations in gels, ointments, fatty ointments, creams, pastes, powders, milk and tinctures are possible. The dosage of the compounds of general formula I should be 0.01%-20% in these preparations to achieve a sufficient pharmacological action.


The invention also comprises the compounds of general formula I according to the invention as therapeutic active ingredients.


In addition, the compounds of general formula I according to the invention are part of the invention as therapeutic active ingredients together with pharmaceutically compatible and acceptable adjuvants and vehicles.


The invention also comprises a pharmaceutical composition that contains one of the pharmaceutically active compounds according to the invention or mixtures thereof or a pharmaceutically compatible salt thereof and a pharmaceutically compatible salt or pharmaceutically compatible adjuvants and vehicles.


The compounds of general formula (I) according to the invention can optionally also be formulated and/or administered in combination with other active ingredients.


The invention further relates to combination therapies or compositions wherein a GR agonist of formula (I), or a pharmaceutically acceptable salt thereof, or a pharmaceutical composition comprising a GR agonist of formula (I), or a pharmaceutically acceptable salt thereof, is administered concurrently (possibly in the same composition) or sequentially with one or more agents for the treatment of any of the above disease states.


For example, for the treatment of rheumatoid arthritis, osteoarthritis, COPD, asthma or allergic rhinitis a GR agonist of the invention can be combined with one or more agents for the treatment of such a condition. Where such a combination is to be administered by inhalation, then the one or more agents is selected from the list comprising:
