Description: 583 AMINOBENZOPHENONES AS INHIBITORS OF IL-lβ AND TNF-α FIELD OF THE INVENTION This invention relates to a hitherto unknown class of compounds which shows anti- inflammatory effects, to pharmaceutical preparations containing these compounds, to dosage units of such preparations, and to their use in the treatment and prophylaxis of asthma, allergy, arthritis, including rheumatoid arthritis and spondyloarthritis, gout, atherosclerosis, chronic inflammatory bowel disease (Crohn's disease), proliferative and inflammatory skin disorders, such as psoriasis and atopic dermatitis, uveitis, septic shock, AIDS, and acne. BACKGROUND OF THE INVENTION Previously, a series of closely related aminobenzophenones (e.g. 4-(2-amino-4- nitrophenylamino)benzophenone) have been described (Hussein, F.A. et al, Iraqi J. Sci., 22, 54-66 (1981)). However, there is no description of their uses. PCT/DK98/00008 discloses aminobenzophenone inhibitors of interleukin lβ (IL-lβ) and tumour necrosis factor a (TNF-α) secretion in vitro, said compounds being potentially useful for treatment of inflammatory diseases in which the production of cytokines is involved in the pathogenesis, e.g. asthma, rheumatoid arthritis, psoriasis, contact dermatitis, and atopic dermatitis. Furthermore the compounds of PCT/DK98/00008 was tested in vivo for anti- inflammatory properties in the 12-0-tetradecanoylphorbol-13-acetate (TPA) induced murine chronic skin inflammation model, (De Young, L.M. et al, Agents Actions, 26, 335- 341 (1989); Carlson, R.P. et al, Agents Actions, 17, 197-204 (1985); Alford, J.G. et al, Agents Action, 37, (1992); Stanley, P.L. et al, Skin Pharmacol, 4, 262-271 (1991)). In this chronic skin inflammation model the compounds had the same potency compared to the reference compound hydrocortisone. The purpose of the present invention is to provide further pharmacologically active aminobenzophenone derivatives and related compounds. This purpose is achieved with the novel aminobenzophenone derivatives according to the general formula I that are potent inhibitors of interleukin lβ (IL-lβ) and tumour necrosis factor α (TNF-α) secretion in vitro, making them potentially useful for treatment of inflammatory diseases, in which the secretion and regulation of cytokines or more specifically interleukin lβ (IL-lβ) and tumour necrosis factor α (TNF-α) are involved in the pathogenesis. The inhibition or down regulation of the cytokines is possibly due to an inhibition of MAP kinases.

Pharmacological methods To study the effect of the compound of the present invention in vitro the inhibition of the IL-lβ and TNF-α secretion was measured using the following procedure: Cytokine production was measured in the media from lipopolysaccharide (LPS) stimulated peripheral blood mononuclear cells. The mononuclear cells were isolated from human peripheral blood by Lymphoprep® (Nycomed, Norway) fractionation and suspended in RPMI 1640 (growth medium) with foetal calv serum (FCS, 2%), at a concentration of 5 x 10 5 cells/ml. The cells were incubated in 24-well tissue culture plates in 1 ml aliquots. Test compounds were dissolved in dimethylsulfoxide (DMSO, 10 mM) and were diluted with the medium. Compounds were added to the cells for 30 minutes, then LPS (1 mg/ml final concentration) was added. The plates were incubated for 18 hours, and the concentration of IL-lβ and TNF-α in the medium was determined by enzyme-linked immuno- sorbent assays. The median inhibitory concentrations (IC 5 g) of the compounds were calculated. The results are shown in Table 1. The compounds of the present invention also show similar activities in the ability to inhibit PMN (polymor ' phonuclear) superoxide secretion which is also indicative of potentially useful anti-inflammatory drugs. The compounds were tested using the following procedure: Human polymorphonuclear (PMN) granulocytes were isolated from human blood by dextran sedimentation, Lymphoprep® fractionation and hypotonic lysis of contaminating erythrocytes. Superoxide anion generation was measured as the superoxide dismutase inhibitable reduction of ferricytochrome C (Madhu, S.B. et al, Inflammation, ϋ 241, (1992)). The cells were suspended in Hanks' balanced salt solution, and incubated for 10 minutes at 37°C with test compounds. The cells were primed by the addition of TNF-α (3 ng/ml final concentration) for 10 minutes, and then ferricytochrome C, (final concentration 750μg/ml), bovine serum albumin (BSA, final concentration 1 mg/ml) and formyl-methio- nyl-leucyl-phenylalanine (fMLP, final concentration 10 "7 M) were added for 3 minutes. The cells were chilled on ice, and were spun down. The optical densities in the cell-free supernatant was measured in a spectrophotometer. The median inhibitory concentration (IC 50 ) of the compounds was calculated. The results are shown in Table 1. Table 1 ref. a) : 4-(2-Aminophenylamino)-2-chloro-2'-methylbenzophenone, compound 106 disclosed in PCT/DK98/00008. ref b) : Ethyl Λ/-[2-[3-chloro-4-(2-methylbenzoyl)- phenylamino]phenyl]carbamate, compound 173 disclosed in PCT/DK98/00008. These results show that the compounds of the present invention are able to inhibit the production of IL-lβ, TNF-α and PMN-superoxide, thus making them potentially useful in the treatment of inflammatory diseases. To study the compounds of the present invention in vivo the 12-O-tetradecanoylphorbol- 13-acetate (TPA) induced murine chronic skin inflammation model can be used (De Young, L.M. et al, Agents Actions, 26, 335-341 (1989); Carlson, R.P. et al, Agents Actions, 17, 197-204 (1985); Alford, J.G. et al, Agents Action, 3Z, (1992); Stanley, P.L. et al, Skin Pharmacol, 4, 262-271 (1991)), cf. description of method in PCT/DK98/00008 hereby incorporated by reference. These results shows that the compounds of the present invention are of the same potency compared to known reference compounds, e.g. hydrocortisone with its known side effects, whereas the compounds of the present invention are well tolerated and are non-toxic. Some members of the present class of compounds show a very low absorption, thus making them especially useful in the treatment of various dermatological diseases. In general, they may be administered by e.g. oral, intravenous, intranasal, topically or transdermal routes. Method of preparation The compounds of the present invention can be prepared in a number of ways well known to those skilled in the art of organic synthesis. The compounds of the present invention can be synthesised using the methods outlined below, together with methods known in the art of synthetic organic chemistry, or variations thereof as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. The novel compounds of formula I may be prepared using the reactions and techniques described in this section. The reactions are performed in solvents appropriate to the reagents and materials employed and are suitable for the transformations being effected. Also, in the synthetic methods described beiow, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of experiment and work-up procedures, are chosen to be conditions of standard for that reaction, which should be readily recognised by one skilled in the art. It is understood by one skilled in the art of organic synthesis that the functionality present on various portions of the educt molecule must be compatible with the reagents and reactions proposed. Not all compounds of formula I falling into a given class may be compatible with some of the reaction conditions required in some of the methods described. Such restrictions to the substituents which are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternate methods can be used. Where Z = Cl, 4-NO 2 PhO or rv, (Q = bond) other suitable leaving group and lr R 2 , R3, R4, X, and Y have the above meanings. Scheme 1 Compounds according to the present invention may be prepared by a process comprising coupling of an amine of the formula II with an chloroformate ester, 4-nitrophenylformate ester, or other suitable activated derivatives of the formula III, as shown in scheme 1, where R l7 R 2 , R3, R 4 , Q, X, and Y are as defined in general formula I, except that any substituents or functional group which are potentially reactive in the coupling reaction may themselves be protected before the coupling reaction is performed and subsequently removed. Especially in the case were Q represents bond compounds of the present invention may conveniently be prepared by a process were the reactive intermediate of the formula III is first formed in situ from the corresponding alcohol of the general formula IV, e.g. by treatment with phosgene, bis(trichloromethyl) carbonate, di(2-pyridyl) carbonate, or the like, and then treated with the amine of the general formula II, where R lr R2, R3, R , X, and Y are as defined in general formula I, except that any substituents or functional group which are potentially reactive in the coupling reaction may themselves be protected before the coupling reaction is performed and subsequently removed. Compounds accordingly to the present invention with the general formula II(X=0) may be prepared by several methods known to those skilled in the art of organic synthesis. One useful sequence is shown in scheme 2 were the key process comprising coupling of an amine of the formula VII with an fluoride, chloride, bromide, iodide, or triflate with the formula VIII, as shown in Scheme 2, where R-^, R2, R3, and, R 4 are as defined in general formula I, to give a coupled product with the general formula VI, except that any substituents or functional group which are potentially reactive in the coupling reaction may themselves be protected before the coupling reaction is performed and subsequently removed. This compound VI may then be reduced to the corresponding amine with the general formula II by treatment with standard reducing agents. Examples of such reducing agents include, but are not limited to, stannous chloride dihydrate; hydrogen, ammonium formiate, or hydrazine hydrate and a catalytic amount of palladium on carbon.

Scheme 2 The coupling reaction is carried out using any of the methods for the formation of diphenylamines known to one skilled in the art of organic synthesis. The preferred method is the nucleophilc aromatic substiution method which comprising coupling of an amine with an arylfluoride or arylchloride in the presence of a base, in an suitable solvent. Especially potassium-tert-butoxide (KOt-Bu), sodium-tert-butoxide (NaOt-Bu), sodium hydrid (NaH), and potassium hydride (KH) have proven to be the best bases in this process, but other bases may be used as well. The reaction is typically performed at ambient temperature (20-25 °C) in dipolar aprotic solvents like dimethylsulfoxide (DMSO), dimethylformamide (DMF), or Λ/-methylpyrroli- done (NMP) under an inert atmosphere like argon or nitrogen. Alternatively, the coupling reaction can be done by the palladium catalysed amination method which comprising coupling of an amine with an arylhalogenide (iodide, bromide, triflate, or in some cases chloride) in the presence of a base, a suitable Pd source, and a suitable phosphine ligand in an inert solvent. The palladium compound used in the process is not particularly limited, and as specific examples are palladium(II) acetate, palladium(II) chloride, palladium(II) bromide, dichlorobis(triphenylphosphine)palladium(II), tetrakis(triphenylphosphine)palladium(0), tris(dibenzylideneacetone)dipalladium(0).

The amount of palladium and ligand used in this process is typically in the range 0.1 to 10 % by mole relative to the amount of the aromatic halide (or triflate) used. Especially sodium-tert-butoxide (NaOt- Bu) and caesium carbonate (CS2CO3) have proven to be the best bases in this process, but other bases may be used as well. The reaction is typically performed at elevated temperature (80-120 °C) in inert solvents like 1,4-dioxane, toluene, benzene and tetrahydrofurane under an inert atmosphere like argon or nitrogen. Compounds according to the present invention in which R 4 is not hydrogen may be prepared by a process comprising coupling of an amine of the formula VI (R 4 = H) with an alkylating agent, as shown in scheme 2, where R-^, R 2 , R3, and, R 4 are as defined in general formula I, except that any substituents or functional group which are potentially reactive in the coupling reaction may themselves be protected before the coupling reaction is performed and subsequently removed. Typically alkylating agents of the general formula R-Y include, but are not limited to, iodides (Y=I), bromides (Y=Br), chlorides (Y=CI) and sulfonates (Y=OS0 2 R', where R' represents methyl, trifluoromethyl or 4-methylphenyl). Compounds according to the present invention may in special cases be prepared by a simple functional group interconversion (FGI), meaning a standard process, known to those skilled in the art of organic synthesis, where a functional group in compounds with the general formula I (or any other intermediate described herein) is transformed into a different functional group in one or more synthetic steps, leading to a new compound with the general formula I. Examples of such processes are, but are not limited to, hydrolysis of an ester to give an acid under basic conditions; deprotection of an methylether to give an phenol by treatment with e.g. borontribromide (BBr3); and catalytic hydrogenation of an olefin to give an saturated hydrocarbon. Compounds according to the present invention in which C=X represents -(CS)- may be prepared from compounds of the invention (or any other intermediate described herein) in which C=X represents -(CO)- by a process using an appropiate thiocarbonyiating agent such as phosphorous pentasulfide (P 4 S 10 )' or Lawesson's reagent (2,4-bis(4- methoxyphenyl)-l,3,2,4-dithiaphosphetane-2,4-disulfide) or the like. XI Coupling IX VII hal: Br, I and R l and R 2 have the above meanings. SCHEME 3 Compounds accordingly to the present invention with the general formula VII may be prepared by several methods known to those skilled in the art of organic synthesis. One useful sequence is shown in Scheme 3. The key step comprises coupling of a bromide (or iodide) with the general formula X with an acid chloride with the general formula XI to afford the benzophenone with the general formula IX. This compound IX may then be reduced to the corresponding amine with the general formula VII by treatment with standard reducing agents. Examples of such reducing agents include, but are not limited to, stannous chloride dihydrate; hydrogen, ammonium formiate, or hydrazine hydrate and a catalytic amount of palladium on carbon. The coupling reaction is done by transforming the bromide (X) into a reactive organometallic intermediate, e.g. by treatment with butyllithium to afford the lithium derivative or by treatment with magnesium to afford the magnesium derivative. The reactivity of this intermediate is then modulated by transme- tallation to e.g. zinc, by treatment with ZnCI 2 , ZnBr 2 , or Znl 2 - This organozinc compound is then coupled with the acid chloride, with the general formula XI, under the influence of a palladium(O) complex in catalytic amount. Examples of such catalyst include but are not particularly limited to tetrakis(triphenylphosphine)palladium(0), tetrakis(triphenylarsine)- palladium(O), dichlorobis(triphenylphosphine)palladium(II), or benzylchlorobis(triphenyl- phosphine)palladium(II). It may be more advantageous in some cases to alter the sequence of the processes described above. The described sequence of processes is not considered as being limited for the preparation of the compounds of the present invention with the general formula I and alteration of the reaction sequence is an obvious alternative for those skilled in the art of organic synthesis. The present compounds are intended for use in pharmaceutical compositions which are useful in the treatment of the above mentioned diseases. The amount required of a compound of formula I (hereinafter referred to as the active ingredient) for therapeutic effect will, of course, vary both with the particular compound, the route of administration and the mammal under treatment. A suitable dose of a com- pound of formula I for systemic treatment is 0.1 to 200 mg/kg bodyweight, the most preferred dosage being 0.2 to 50 mg/kg of mammal bodyweight, administered one or more times daily. While it is possible for an active ingredient to be administered alone as the raw chemical, it is preferable to present it as a pharmaceutical formulation. Conveniently, the active ingredient comprises from 0.1% to 100% by weight of the formulation. Conveniently, dosage units of a formulation contain between 0.07 mg and 1 g of the active ingredient. For topical administration, the active ingredient preferably comprises from 1% to 20% by weight of the formulation but the active ingredient may comprise as much as 50% w/w. Formulations suitable for nasal or buccal administration may comprise 0.1% to 20% w/w. for example about 2% w/w of active ingredient. By the term "dosage unit" is meant a unitary, i.e. a single dose which is capable of being administered to a patient, and which may be readily handled and packed, remaining as a physically and chemically stable unit dose comprising either the active material as such or a mixture of it with solid or liquid pharmaceutical diluents or carriers. The formulations, both for veterinary and human medical use, of the present invention comprise an active ingredient in association with a pharmaceutically acceptable carrier therefore and optionally other therapeutic ingredient(s). The carrier(s) must be "acceptable" in the sense of being compatible with the other ingredients of the formulations and not deleterious to the recipient thereof. The formulations include those in a form suitable for oral, ophthalmic, rectal, parenteral (including subcutaneous, intramuscular and intravenous), transdermal, intra-articular, topical, nasal, or buccal administration. The formulations may conveniently be presented in dosage unit form and may be prepared by any of the .methods well known in the art of pharmacy. All methods include the step of bringing the active ingredient into association with the carrier which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing the active ingredient into association with a liquid carrier or a finely divided solid carrier or both, and then, if necessary, shaping the product into the desired formulation. Formulations of the present invention suitable for oral administration may be in the form of discrete units as capsules, sachets, tablets or lozenges, each containing a prede- termined amount of the active ingredient; in the form of a powder or granules; in the form of a solution or a suspension in an aqueous liquid or non-aqueous liquid; or in the form of an oil-in-water emulsion or a water-in-oil emulsion. The active ingredient may also be administered in the form of a bolus, electuary or paste. Formulations for rectal administration may be in the form of a suppository incorporating the active ingredient and a carrier such as cocoa butter, or in the form of an enema. Formulations suitable for parenteral administration conveniently comprise a sterile oily or aqueous preparation of the active ingredient which is preferably isotonic with the blood of the recipient. Formulations suitable for intra-articular administration may be in the form of a sterile aqueous preparation of the active ingredient which may be in microcrystalline form, for example, in the form of an aqueous microcrystalline suspension. Liposomal formulations or biodegradable polymer systems may also be used to present the active ingredient for both intra articular and ophthalmic administration. Formulations suitable for topical administration, including eye treatment, include liquid or semi-liquid preparations such as liniments, lotions, gels, applicants, oil-in-water or water-in-oil emulsions such as creams, ointments or pastes; or solutions or suspensions such as drops. Formulations suitable for administration to the nose or buccal cavity include powder, self- propelling and spray formulations, such as aerosols and atomizers. In addition the aforementioned ingredients, the formulations of this invention may include one or more additional ingredients. The compositions may further contain other therapeutically active compounds usually applied in the treatment of the above mentioned pathological conditions, for instance glucocorticoids, vitamin D's, anti-histamines, platelet activating factor (PAF) antagonists, anticolinergic agents, methyl xanthines, β-adrenergic agents, salicylates, indomethacin, flufenamate, naproxen, timegadine, gold salts, penicillamine, serum cholesterol-reducing agents, retinoids, zinc salts, and salicylazosulfapyridin (Salazopyrin). The novel compounds of the invention are of value in the human and veterinary practice as systemic and topical therapeutic agents for the treatment and prevention of diseases. The novel compounds show anti-acne properties and, i.a., anti-inflammatory and cytokine regulating effects possibly due to MAP kinase inhibition, and are useful in the treatment and prophylaxis of asthma, allergy, arthritis, including rheumatoid arthritis and spondylo- arthritis, gout, atherosclerosis, chronic inflammatory bowel disease (Crohn's disease), proliferative and inflammatory skin disorders, such as psoriasis, atopic dermatitis, uveitis, septic shock, AIDS, and osteoporosis. The invention will now be further described in the following non-limiting general procedures, preparations and examples.
