The invention relates to imidazolidine-2,4-diones which are substituted by an aralkyl radical and to the physiologically compatible salts thereof.
Structurally similar imidazoline-2,4-diones have already been described in U.S. Pat. No. 5,411,981. WO2004/031160A2 discloses structurally similar compounds, but these always bear a thiocarbonyl group on the imidazolidine ring. The most structurally similar examples 42, 90 and 116 from WO2004/031160A were, like the inventive compounds, tested in the hCB1R FLIPR assay and exhibited an IC50 value of >10 μm and therefore have to be considered as inactive.
It was an object of the invention to provide compounds which display a therapeutically utilizable action. In particular, it was an object of the invention to find novel compounds which are suitable for the treatment of metabolic syndrome, of type II diabetes and of obesity.

The aryl radicals may be mono- or polysubstituted by suitable groups as described above.
A heteroaryl radical is understood to mean aromatic rings and ring systems which, apart from carbon, also contain heteroatoms, for example nitrogen, oxygen or sulfur. This definition also includes ring systems in which the heteroaryl radical is fused to benzene rings.

According to one of its aspects, the invention relates to the use of a compound of the formula I, the pharmaceutically acceptable salts thereof and the solvates or hydrates thereof for the treatment of the above-specified disorders and diseases.
The compound(s) of the formula I may also be administered in combination with further active ingredients.
The amount of a compound of the formula I which is required in order to achieve the desired biological effect is dependent upon a series of factors, for example the specific compound selected, the intended use, the mode of administration and the clinical condition of the patient. The daily dose is generally in the range from 0.3 mg to 100 mg (typically from 3 mg to 50 mg) per day per kilogram of bodyweight, for example 3-10 mg/kg/day. An intravenous dose may, for example, be in the range from 0.3 mg to 1.0 mg/kg and may suitably be administered as an infusion of from 10 ng to 100 ng per kilogram per minute. Suitable infusion solutions for these purposes may, for example, contain from 0.1 ng to 10 mg, typically from 1 ng to 10 mg, per milliliter. Single doses may contain, for example, from 1 mg to 10 g of the active ingredient. Ampoules for injections may therefore contain, for example, from 1 mg to 100 mg, and single dose formulations which can be administered orally, for example tablets or capsules, may contain, for example, from 1.0 to 1000 mg, typically from 10 to 600 mg. The compounds of the formula I may be used for therapy of the above-mentioned conditions as the compounds themselves, although they are preferably in the form of a pharmaceutical composition with an acceptable carrier. The carrier of course has to be acceptable, in the sense that it is compatible with the other constituents of the composition and is not damaging to the health of the patient. The carrier may be a solid or a liquid or both and is preferably formulated with the compound as a single dose, for example as a tablet, which may contain from 0.05 to 95% by weight of the active ingredient. Further pharmaceutically active substances may likewise be present, including further compounds of the formula I. The inventive pharmaceutical compositions may be produced by one of the known pharmaceutical methods which consist essentially in mixing the constituents with pharmacologically acceptable carriers and/or excipients.
Inventive pharmaceutical compositions are those which are suitable for oral, rectal, topical, peroral (for example sublingual) and parenteral (for example subcutaneous, intramuscular, intradermal or intravenous) administration, although the most suitable mode of administration depends in each individual case on the nature and severity of the condition to be treated and on the type of the compound of the formula I used in each case. Coated formulations and coated slow-release formulations are also encompassed by the scope of the invention. Preference is given to acid- and gastric fluid-resistant formulations. Suitable gastric fluid-resistant coatings include cellulose acetate phthalate, polyvinyl acetate phthalate, hydroxypropylmethylcellulose phthalate and anionic polymers of methacrylic acid and methyl methacrylate.
Suitable pharmaceutical preparations for oral administration may be in the form of separate units, for example capsules, cachets, lozenges or tablets, each of which contains a certain amount of the compound of the formula I; as powder or granules; as solution or suspension in an aqueous or nonaqueous liquid; or as an oil-in-water or water-in-oil emulsion. These compositions may, as already mentioned, be prepared by any suitable pharmaceutical method which includes a step in which the active ingredient and the carrier (which may consist of one or more additional constituents) are brought into contact. In general, the compositions are prepared by uniform and homogeneous mixing of the active ingredient with a liquid carrier and/or finely divided solid carrier, after which the product is shaped if necessary. For example, a tablet can thus be produced by compressing or shaping a powder or granules of the compound, optionally with one or more additional constituents. Compressed tablets can be prepared by tableting the compound in free-flowing form, for example a powder or granules, optionally mixed with a binder, lubricant, inert diluent and/or one (or more) surfactants/dispersants in a suitable machine. Shaped tablets can be prepared by shaping the pulverulent compound moistened with an inert liquid diluent in a suitable machine.
Pharmaceutical compositions which are suitable for peroral (sublingual) administration include lozenges which contain a compound of the formula I with a flavoring, customarily sucrose, and gum arabic or tragacanth, and pastilles which include the compound in an inert base, such as gelatin and glycerol or sucrose and gum arabic.
Suitable pharmaceutical compositions for parenteral administration include preferably sterile aqueous preparations of a compound of the formula I which are preferably isotonic with the blood of the intended recipient. These preparations are preferably administered intravenously, although the administration may also be subcutaneous, intramuscular or intradermal as an injection. These preparations can preferably be produced by mixing the compound with water and making the solution obtained sterile and isotonic with the blood. Injectable compositions according to the invention generally contain from 0.1 to 5% by weight of the active compound.
Suitable pharmaceutical compositions for rectal administration are preferably in the form of single dose suppositories. These can be prepared by mixing a compound of the formula I with one or more conventional solid carriers, for example cocoa butter, and shaping the resulting mixture.
Suitable pharmaceutical compositions for topical application on the skin are preferably in the form of an ointment, cream, lotion, paste, spray, aerosol or oil. Useful carriers include petroleum jelly, lanolin, polyethylene glycols, alcohols and combinations of two or more of these substances. The active ingredient is generally present in a concentration of from 0.1 to 15% by weight of the composition, for example from 0.5 to 2%.
Transdermal administration is also possible. Suitable pharmaceutical compositions for transdermal applications may be in the form of single plasters which are suitable for long-term close contact with the epidermis of the patient. Such plasters suitably contain the active ingredient in an optionally buffered aqueous solution, dissolved and/or dispersed in an adhesive or dispersed in a polymer. A suitable active ingredient concentration is from approx. 1% to 35%, preferably from approx. 3% to 15%. A particular means of releasing the active ingredient may be by electrotransport or iontophoresis, as described, for example, in Pharmaceutical Research, 2(6): 318 (1986).
Further suitable active ingredients for the combination preparations are:
All antidiabetics which are mentioned in the Rote Liste 2007, chapter 12; all weight-reducing agents/appetite suppressants which are mentioned in the Rote Liste 2007, chapter 1; all diuretics which are mentioned in the Rote Liste 2007, chapter 36; all lipid-lowering agents which are mentioned in the Rote Liste 2007, chapter 58. They can be combined with the compound of the invention of the formula I in particular for a synergistic improvement in action. The active ingredient combination can be administered either by separate administration of the active ingredients to the patient or in the form of combination products in which a plurality of active ingredients are present in one pharmaceutical preparation.

The invention further provides processes for preparing the compounds of the general formula I, wherein the compounds of the formula I are obtained in a procedure analogous to the reaction schemes which follow.
In a first method “A”, the procedure is to convert a suitably substituted aniline of the formula A in which the R1 to R5 radicals are in some circumstances present in protected form to an isocyanate of the formula B. This reaction can be carried out, for example, with phosgene in toluene or with diphosgene or triphosgene. The isocyanate B is subsequently reacted with the methyl ester or another ester (e.g. tert-butyl) of the amino acid J in which R and R′ are each as defined in formula I, or a salt of an ester of the amino acid J, with addition of base (e.g. triethylamine), to give a urea of the formula K. This urea can be ring-closed under basic or acidic conditions, preferably acidic conditions, to give the imidazolidine-2,4-dione of the formula L. The further conversion to a compound of the formula H, which constitutes the ortho-substituted special case of a compound of the formula I, can, for example, be effected by alkylating a suitably substituted compound Q where Z may be one or more substituents as described above in formula I, and Y is either a protected hydroxyl radical OR where R is, for example, acetyl, tert-butyl, benzyl or p-methoxybenzyl, or Y is a halogen radical, for example chlorine or bromine, and V is either a halogen atom, preferably a chlorine or bromine atom, or else, for example, an O—SO2—C6H4-4-CH3 radical or an O—SO2—CH3 radical or an O—SO2—CF3 radical, to obtain the compound M. After conversion by means of standard reactions of the Y radical defined as OR to a Y′ radical defined as OH, M can be reacted further by copper catalysis under Ullmann conditions (e.g.: R. Frian, D. Kikelj: Synthesis 2006, 2271-2285) with aryl or heteroaryl halides, preferably bromides, to give compounds of the formula H. W in R19-W of the formula O is defined, for example, as —Br. This reaction can alternatively also be carried out in such a way that the Y radical in the compound Q is a halogen atom (e.g. bromine or chlorine). This compound of the formula M can then be reacted in a next step with a compound of the formula R19-W in which W is defined as —OH, under the copper-catalyzed conditions outlined above, to give a compound of the formula H.
Instead of the copper-catalyzed Ullmann reaction, it is also possible to utilize the palladium-catalyzed diaryl ether coupling reaction (e.g.: A. Aranyos et al.: J. Am. Chem. Soc. 121 (1999) 4369-4378).
A further variant is that of intermolecular nucleophilic substitution (see, for example: F. Li et al.: Synthesis 2005, 1305; M. Chaouchi et al.: Eur. J. Org. Chem. 2002, 1278; S.-L. Cui et al.: Synlett 2004, 1829).
A further useful variant is that of the cross-coupling of phenols with aryl- or heteroarylboronic acids or trifluoroborates (see, for example: D. M. T. Chan et al.: Tetrahedron Lett. 39 (1998) 2933; D. M. T. Chan et al.: Tetrahedron Lett. 44 (2003) 3863; T. D. Quach et al.: Org. Lett. 5 (2003) 1381). This reaction can be conducted in such a way that either a compound of the formula M in which Y′ is OH is reacted with a compound of the formula O in which W is —B(OH)2 or —BF3−K+ to give a compound of the formula H in which Y″ is oxygen. Or a compound of the formula Min which Y′ is —B(OH)2 or BF3−J+ is reacted with a compound of the formula O in which W is hydroxyl.
In a corresponding manner, P can be reacted with O to give N, which is then reacted with L to give H.
Any protecting groups present in the compound H can be removed at the end.
The process described here can also be applied correspondingly to other chalcogen derivatives, for example diaryl thioethers.
The formula H shown here constitutes a special case of the formula I in which the Y″-R19 radical in formula I is in the ortho position; this radical may correspondingly also be in the meta or para position.
In another method “B”,
the isocyanate B is reacted with a suitably substituted amino acid ester derivative C in which the particular substituents may be provided with protecting groups, and where the methyl ester shown in the scheme is a nonlimiting example of an ester, and where Y is either a protected hydroxyl radical OR where R is, for example, acetyl, tert-butyl, benzyl or p-methoxybenzyl, or Y is a halogen radical, for example chlorine or bromine, with addition of a base (e.g. triethylamine), to give a urea of the formula F. The amino acid ester derivative C can be prepared from the compound D in which Z may be one or more substituents as described above in formula I, and where Y is either a protected hydroxyl radical OR where R is, for example, acetyl, tert-butyl, benzyl or p-methoxybenzyl, or Y is a halogen radical, for example chlorine or bromine, and X is a (CH2)p—U moiety in which U may be defined as Cl, Br, I, O—SO2—C6H4-4-CH3, O—SO2—CH3 or O—SO2—CF3, with an amino acid ester of the formula E in which R and R′ are each as defined in formula I, under alkylating conditions. Alternatively, the compound of the formula C can be obtained by reductive amination of the aldehyde D (Z and Y as described above and X═(CH2)p—CHO) with the amino acid derivative E. The urea F can be ring-closed under basic or acidic conditions, preferably acidic conditions, to give the imidazolidine-2,4-dione of the formula G. A protected hydroxyl radical OR where R is, for example, acetyl, tert-butyl, benzyl or p-methoxybenzyl, in the compounds of the formula G can be converted to an —OH function by standard reactions. According to whether Y in the compound of the formula G is —OH or halogen (e.g. Cl or Br), reaction with compounds of the formula O in which W is either boronic acid (boronic ester) or —OH can prepare compounds of the formula H. Otherwise, the procedures described under “method A” for the reaction of G with O to give H apply.
Any protecting groups present in the compound H can be removed at the end of the reaction sequence.
The process described here can also be applied correspondingly to other chalcogen derivatives, for example diaryl thioethers.
The formula H shown here constitutes a special case of the formula I in which the Y″-R19 radical in formula I is in the ortho position; this radical may correspondingly also be in the meta or para position.
In a further method (method “C”),
p-methoxybenzyl isocyanate B′ is reacted with an amino acid ester, for example E in which R and R′ are each as defined in formula I, under basic conditions, to give the urea K′. The urea K′ can be ring-closed under basic or acidic conditions, preferably acidic conditions, to give the imidazolidine-2,4-dione of the formula L′. The compounds M′ are obtained by reacting the compounds L′ with the compounds Q under alkylating conditions. Z, V and Y of the compounds Q are each defined as specified in method “A”. The p-methoxybenzyl group in the compounds M′ can be eliminated oxidatively to obtain the compounds T. The N-arylation of the imide nitrogen atom in compounds of the formula T using arylboronic acids of the formula S by processes as described, for example, in J.-B. Lan et al.: SYNLETT 2004, 1095-1097 or D. M. T. Chan et al.: Tetrahedron Lett. 1998, 39, 2933-2936, affords compounds of the formula G′. After conversion by means of standard reactions of the Y radical to a Y′ radical defined as —OH or obtaining the Y radical ═Y′=halogen, the compounds of the formula H can be obtained by reaction with compounds of the formula O as described above for method “A”.
Any protecting groups present in the compound H can be removed at the end. The process described here can also be applied correspondingly to other chalcogen derivatives, for example diaryl thioethers.
The formula H shown here constitutes a special case of the formula I in which the Y″-R19 radical in formula I is in the ortho position; this radical may correspondingly also be in the meta or para position.
The examples which follow serve to illustrate the invention in detail, without limiting it to the products and embodiments described in the examples.

Pharmacological Testing:
In Vitro Tests:
In vitro functional assays with recombinant cells:
Function-testing assays were performed by means of the FLIPR technique (“Fluorometric Imaging Plate Reader”, Molecular Devices Corp.).
To this end, ligand-induced changes in the intracellular concentration of Ca2+ in recombinant HEK293 cells, which expressed both a cannabinoid receptor (CB1 or CB2) and G-protein Galpha16, were determined. For the studies, cells were sown into 96-well microtiter plates (60 000 cells/well) and left to grow overnight. The medium was removed and the cells were incubated in buffer which contained the fluorescent dye Fluo-4. After this loading with dye, the cells were washed, test substance was added dissolved in buffer, the mixture was incubated for 20 minutes, a known cannabinoid receptor agonist as a reference agonist was added in buffer and, finally, the changes in the intracellular Ca2+ concentration were measured in the FLIPR unit.
Results were presented as the percentage change relative to the control (0%: analogous experiment without test substance and without reference agonist, i.e. only with buffer; 100%: analogous experiment without test substance, but with reference agonist in excess), and used to calculate dose/action curves, and IC50 values were determined.
Results:
The values of the functional assay compared to the cannabinoid 1 receptor including illustrative selectivities compared to the cannabinoid 2 receptor can be taken from table 3 which follows.
Binding to the CB1 Receptor:
Test compounds: The compounds (3 μl, 10 mM, 100% DMSO), pipetted into 96-well PP microtiter plates, were diluted with 27 μl of 100% DMSO (dimethyl sulfoxide). Proceeding from this solution, further 3-fold dilution steps were undertaken by transferring 10 μl in each case to a new PP microtiter plate and adding a further 20 μl of 100% DMSO. In each case 6 μl of these solutions were transferred into new 96-well PP microtiter plates and made up with 144 μl of assay buffer. The end concentrations ranged from 10 μM to 0.005 μM.
Negative control: AM 251, dissolved in assay buffer with 1% DMSO, was added to the dilution series in the microtiter plates as a control. The end concentration was 1 μM.
Blank control: assay buffer with 1% DMSO was added to the dilution series of the microtiter plates as a blank control.
Summary of the Assay Parameters:
The values were calculated using the corrected raw data.
The values reported were obtained as average values of a double determination. The IC50 values were calculated from the measurements with the program Xlfit, formula 205. Ki values were obtained from the IC50 and Kd values utilizing the Cheng-Prusoff equation:
Literature: Cheng, Y.-C., and Prusoff, W. H. (1973) Biochem. Pharmacol 22, 3099-3108 Results: Ki values of example compounds;
It can be seen from the test data that the inventive compounds of the formula I act as CB1R antagonists and are therefore very suitable for treating metabolic syndrome, type II diabetes and obesity.
In Vivo Tests:
“Milk consumption in mice”
The test is used to study the anorexigenic potency of the test substances. Female NMRI mice, 25-35 g in weight, are used. The mice are accustomed to the housing conditions for at least one week and to the condensed milk supplied for 2 days.
The feed is removed from the mice for 24 hours, but they have constant access to water. On the day of the experiment, the animals are put in individual cages; the cage lids can accommodate the pipettes filled with milk. The test substances are administered orally, intraperitoneally or subcutaneously. After the administration, the mice are put in their cages and receive access to the milk 30 min later. The milk consumption is read off every 30 min over 7 hours; at the same time, obvious changes in behavior of the animals are noted.
“Antagonization of CB1-Mediated Hypothermia”
The test is used to measure the potency of cannabinoid CB1 receptor (CB1) antagonists. What is measured is the extent to which the CB1 antagonists to be tested are capable of preventing or of antagonizing hypothermia induced by a CB1 agonist.
Female NMRI mice, 25-35 g in weight, are used. The mice are accustomed to the housing conditions for at least one week.
At time 0 min, the animals are treated orally, intravenously or intraperitoneally with the CB1 antagonist to be tested. 30 min later, the CB1 agonist CP55.940, 1.25 mg/kg, is administered to the mice intraperitoneally. This brings about a fall in the body temperature by 5-6° C. within 30 min. The body temperature is measured rectally for the first time 30 min before the test substance administration and then every 30 min after this administration, if appropriate immediately before a substance administration, over 4 hours.
The potency of the test substances is reported as the percentage decrease in the area under the temperature-time curve which is formed firstly by the average basal temperature, and secondly by the temperature-time curve, of the animals treated exclusively with the CB1 antagonist.
“Intestinal Motility in Mice”
The method serves firstly to study the influence of test substances themselves on the small intestinal motility, and secondly to study to what extent specifically induced effects on the small intestinal motility can be prevented or antagonized, for example the delay in the intestinal passage by the cannabinoid CB1 agonist CP55.940.
Female NMRI mice with a weight of 25-35 g are used. The mice are accustomed to the housing conditions for at least one week.
The feed is removed from the mice for 24 hours, but they have constant access to water. The test substances are administered orally, intravenously, subcutaneously, but not intraperitoneally. If a specific effect is to be antagonized, the test substance is administered 30-120 min before the specific effector. 30 min after this administration, a defined amount of a dyed, non-caloric filler is introduced into the stomach by gavage. After a further 30 min (the dyed filler has about 80% filled the small intestine at this point), the animals are sacrificed and the small intestine is dissected. The intestinal motility is reported as the passage of the dyed filler compared to the total length of the small intestine in percent. A treatment effect is reported as the difference of this passage to the vehicle control, likewise in percent.
