Very particular preference is given to compounds of the formula I in which one or more radicals have the following meaning: 25 R7, R8, R9 and R10 are, independently of each other, H, F, CI or

CH

3 ; R1, R2, R4, R5 and R6 are H; 30 R3 is F, CI, OF 3 , O-R11 or O-phenyl; R11 is H, (CO-Cs)-alkyl, (Ci-Cs)-alkylene-O-(C 1 -Cs)-alkyl or (C1 C8)-alkyl-OH; 35 and the physiologically tolerated salts thereof.

6 If radicals or substituents can occur more than once in the compounds of the formula I, such as -O-R 1, they can then all, independently of each other, have the given meanings and be identical or different. 5 The invention relates to compounds of the formula I, in the form of their racemates, racemic mixtures and pure enantiomers, and to their diastereomers and mixtures thereof. The alkyl radicals in the substituents R1, R2, R3, R4, R5, R6, R7, R8, R9, 10 R10, R11, R12, R13, R14, R15, R16 and R17 can be either straight-chain or branched. Because of their higher solubility in water as compared with the starting compounds or basal compounds, pharmaceutically tolerated salts are 15 particularly suitable for medical applications. These salts must possess a pharmaceutically tolerated anion or cation. Suitable pharmaceutically tolerated acid addition salts of the compounds according to the invention are salts of inorganic acids, such as hydrochloric acid, hydrobromic acid, phosphoric acid, metaphosphoric acid, nitric acid and sulfuric acid, and also 20 of organic acids, such as acetic acid, benzenesulfonic acid, benzoic acid, citric acid, ethanesulfonic acid, fumaric acid, gluconic acid, glycolic acid, isethionic acid, lactic acid, lactobionic acid, maleic acid, malic acid, methanesulfonic acid, succinic acid, p-toluenesulfonic acid and tartaric acid. Suitable pharmaceutically tolerated basic salts are ammonium salts, 25 alkali metal salts (such as sodium salts and potassium salts), alkaline earth metal salts (such as magnesium salts and calcium salts), trometamol (2 amino-2-hydroxymethyl-1,3-propanediol), diethanolamine, lysine or ethylenediamine. 30 Salts which contain an anion which is not pharmaceutically tolerated, such as trifluoroacetate, also belong within the scope of the invention as useful intermediates for preparing or purifying pharmaceutically tolerated salts and/or for use in nontherapeutic, for example in-vitro, applications. 35 The term "physiologically functional derivative" which is used here denotes any physiologically tolerated derivative of a compound according to the invention of the formula I, e.g. an ester which is able, on being administered to a mammal, such as a human, to form (directly or indirectly) a compound of the formula I or an active metabolite thereof.

7 The physiologically functional derivatives also include prodrugs of the compounds according to the invention, as described, for example, in H. Okada et al., Chem. Pharm. Bull, 1994, 42, 57-61. Such prodrugs can be 5 metabolized in vivo to give a compound according to the invention. These prodrugs may or may not themselves be active. The compounds according to the invention can also be present in different polymorphic forms, e.g. as amorphous and crystalline polymorphous forms. 10 All polymorphous forms of the compounds according to the invention belong within the scope of the invention and are another aspect of the invention. In that which follows, all references to "compound(s) according to formula I" 15 refer to compound(s) of the formula I as described above and to their salts, solvates and physiologically functional derivatives as described herein. The compound(s) of the formula (I) can also be administered in combination with other active compounds. 20 The quantity of a compound according to Formula I which is required in order to achieve the desired biological effect depends on a number of factors, e.g. the specific compound which is selected, the intended use, the nature of administration and the clinical condition of the patient. In general, 25 the daily dose is in the range from 0.3 mg to 100 mg (typically from 3 mg and 50 mg) per day per kilogram of bodyweight, e.g. 3-10 mg/kg/day. An intravenous dose can, for example, be in the range from 0.3 mg to 1.0 mg/kg, which dose can expediently be administered as an infusion of from 10 ng to 100 ng per kilogram per minute. Infusion solutions which are 30 suitable for these purposes can, for example, contain from 0.1 ng to 10 mg, typically from 1 ng to 10 mg, per milliliter. Individual doses can, for example, contain from 1 mg to 10 g of the active compound. Thus, ampoules for injections can, for example, contain from 1 mg to 100 mg, and orally administrable individual dose formulations, such as tablets or 35 capsules, can, for example, contain from 1.0 to 1000 mg, typically from 10 to 600 mg. While, for the therapy of the abovementioned conditions, the compounds according to formula I can be used themselves as compounds, they are preferably present, together with a tolerated excipient, in the form of a pharmaceutical composition. The excipient naturally has to be 8 tolerated in the sense that it is compatible with the other components of the composition and is not harmful to the health of the patient. The excipient can be a solid or a liquid or both and is preferably formulated together with the compound as an individual dose, for example as a tablet, which can 5 contain from 0.05% to 95% by weight of the active compound. Other pharmaceutically active substances can also be present, including other compounds according to formula I. The pharmaceutical compositions according to the invention can be prepared using one of the known pharmaceutical methods, which essentially consist in the constituents being 10 mixed with pharmacologically tolerated excipients and/or auxiliary substances. Pharmaceutical compositions according to the invention are those which are suitable for oral, rectal, topical, peroral (e.g. sublingual) and parenteral 15 (e.g. subcutaneous, intramuscular, intradermal or intravenous) administration, even though 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 nature of the compound according to formula I which is employed in each case. Coated formulations and coated 20 delayed-release formulations also belong within the scope of the invention. Preference is given to formulations which are acid-resistant and gastric juice-resistant. Suitable gastric juice-resistant coatings include cellulose acetate phthalate, polyvinyl acetate phthalate, hydroxypropylmethyl cellulose phthalate and anionic polymers of methacrylic acid and methyl 25 methacrylate. Suitable pharmaceutical compounds for oral administration can be present in separate units, such as capsules, cachets, sucking tablets or tablets which in each case contain a defined quantity of the compound according 30 to formula I; as powders or granules; as a solution or suspension in an aqueous or nonaqueous liquid; or as an oil-in-water or water-in-oil emulsion. As already mentioned, these compositions can be prepared using any suitable pharmaceutical method which comprises a step in which the active compound and the excipient (which can be composed of one or 35 more additional constituents) are brought into contact. In general, the compositions are prepared by uniformly and homogeneously mixing the active compound with a liquid and/or finely divided solid excipient, after which the product is molded, if required. Thus, a tablet, for example, can be prepared by pressing or molding a powder or granulate of the compound, 9 where appropriate together with one or more additional constituents. Pressed tablets can be prepared by tableting the compound in freely flowing form, such as a powder or granulate, where appropriate mixed with a binding agent, lubricant, inert diluent and/or a (several) surface 5 active/dispersing agent(s) in a suitable machine. Molded tablets can be prepared by molding the pulverulent compound, which is moistened with an inert liquid diluent, in a suitable machine. Pharmaceutical compositions which are suitable for peroral (sublingual) 10 administration include sucking tablets, which contain a compound according to formula I together with a flavoring agent, usually sucrose and gum arabic or tragacanth, and lozenges, which comprise the compound in an inert base such as gelatin and glycerol or sucrose and gum arabic. 15 Suitable pharmaceutical compositions for parenteral administration preferably include sterile aqueous preparations of a compound according to formula I which are preferably isotonic with the blood of the intended recipient. These preparations are preferably administered intravenously, even though the administration can also take place as an injection 20 subcutaneously, intramuscularly or intradermally. These preparations can preferably be prepared by mixing the compound with water and making the resulting solution sterile and isotonic with the blood. In general, injectable compositions according to the invention comprise from 0.1 to 5% by weight of the active compound. 25 Suitable pharmaceutical compositions for rectal administration are preferably present as individual dose suppositories. These can be prepared by mixing a compound according to formula I with one or more conventional solid excipients, for example cocoa butter, and molding the 30 resulting mixture. Suitable pharmaceutical compositions for topical use on the skin are preferably present as an ointment, cream, lotion, paste, spray, aerosol or oil. Excipients which can be used are vaseline, lanolin, polyethylene 35 glycols, alcohols and combinations of two or more of these substances. The active compound is generally present at a concentration of from 0.1 to 15% by weight of the composition, for example from 0.5 to 2%.

10 Transdermal administration is also possible. Suitable pharmaceutical compositions for transdermal uses can be present as individual plasters which are suitable for long-term intimate contact with the epidermis of the patient. Such plasters expediently contain the active compound in an 5 aqueous solution, which is, where appropriate, buffered, dissolved and/or dispersed in an adhesive or dispersed in a polymer. A suitable active compound concentration is from approx. 1% to 35%, preferably from approx. 3% to 15%. As a particular possibility, the active compound can, as described, for example, in Pharmaceutical Research, 2(6): 318 (1986), be 10 released by means of electrotransport or iontophoresis. The following are suitable for use as additional active compounds for the combination preparations: All antidiabetics which are named in the Roten Liste [Red List] 2001, 15 Chapter 12. They can be combined with the compounds according to the invention of the formula I, particularly for improving the effect synergistically. The active compound combination can be administered either by administering the active compounds separately to the patient or in the form of combination preparations in which several active compounds 20 are present in one pharmaceutical preparation. Most of the active compounds which are listed below are disclosed in USP Dictionary of USAN and International Drug Names, US Pharmacopeia, Rockville 2001. Antidiabetics include insulin and insulin derivatives, such as Lantus® (see www.lantus.com) or HMR 1964, rapidly acting insulins (see US 6,221,633), 25 GLP-1 derivatives, such as those which were disclosed in WO 98/08871 by Novo Nordisk A/S, and hypoglycemic active compounds which are effective orally. The hypoglycemic active compounds which are effective orally preferably include sulfonylureas, biguanidines, meglitinides, oxadiazolidinediones, 30 thiazolidinediones, glucosidase inhibitors, glucagon antagonists, GLP-1 agonists, calcium channel openers, such as those which were disclosed by Novo Nordisk A/S in WO 97/26265 and WO 99/03861, insulin sensitizers, inhibitors of liver enzymes which are involved in stimulating gluconeogenesis and/or glycogenolysis, modulators of glucose uptake, 35 compounds, such as antihyperlipidemic active compounds and antilipidemic active compounds, which alter fat metabolism, compounds which decrease the intake of foodstuffs, agonists of PPAR and PXR, and active compounds which act on the ATP-dependent potassium channel of the beta cells.

Example A has the structure: O0 F 0 0 F H H F 5 The compounds of the formula I are characterized by advantageous effects on sugar metabolism; in particular, they lower the blood sugar level and are suitable for treating type 2 diabetes. The compounds can therefore be used on their own or in combination with other blood sugar-lowering active 10 compounds (antidiabetics). The compounds of formula I are furthermore suitable for treating late damage in diabetes, such as nephropathy, retinopathy, neuropathy and cardiac infarction, myocardial infarction, peripheral arterial occlusion 15 diseases, thromboses, arteriosclerosis, syndrome X, obesity, inflammations, immune diseases, autoimmune diseases, such as AIDS, asthma, osteoporosis, cancer, psoriasis, Alzheimer's disease, schizophrenia and infectious diseases. 20 The activity of the compounds was tested as follows: Glycogen phosphorylase a activity test The effect of compounds on the activity of the active form of glycogen 25 phosphorylase (GPa) was measured in the reverse direction by monitoring the synthesis of glycogen from glucose 1-phosphate by determining the release of inorganic phosphate. All the reactions were carried out as duplicate determinations in 96-well microtiter plates (Half Area Plates, Costar No. 3696), with the change in absorption due to the formation of the 30 reaction product being measured, at the wavelength specified below, in a Multiscan Ascent Elisa Reader (Lab Systems, Finland). In order to measure the enzymic activity of GPa in the reverse direction, the conversion of glucose 1-phosphate into glycogen and inorganic phosphate was measured in accordance with the general method of Engers et al. (Engers 20 HD, Shechosky S, Madsen NB, Can J Biochem 1970 Jul;48(7): 746-754) but with the following modifications: Human glycogen phosphorylase a (for example containing 0.76 mg of protein/mi (Aventis Pharma Deutschland GmbH), dissolved in buffer solution E (25 mM P-glycerophosphate, pH 7.0, 5 1 mM EDTA and 1 mM dithiothreitol), was diluted with buffer T (50 mM Hepes, pH 7.0, 100 mM KCI, 2.5 mM EDTA, 2.5 mM MgCI 2 .6H 2 0), and addition of 5 mg of glycogen/ml, to a concentration of 10 pg of protein/ml. Test substances were prepared as a 10 mM solution in DMSO and diluted down to 50 pM with buffer solution T. 10 pl of 37.5 mM glucose, dissolved 10 in buffer solution T and 5 mg/ml of glycogen, and also 10 pl of a solution of human glycogen phosphorylase a (10 pg of protein/ml) and 20 pl of glucose 1-phosphate, 2.5 mM, were added to 10 ml of the solution. The basal value of the activity of the glycogen phosphorylase a in the absence of test substance was determined by adding 10 pl of buffer solution T 15 (0.1% DMSO). The mixture was incubated at room temperature for 40 minutes and the inorganic phosphate which was released was measured using the general method of Drueckes et al. (Drueckes P, Schinzel R, Palm D, Anal Biochem 1955 Sep 1;230(10):173-177) but with the following modifications: 50 pl of a stop solution of 7.3 mM ammonium molybdate, 20 10.9 mM zinc acetate, 3.6% ascorbic acid, 0.9% SDS are added to 50 pl of the enzyme mixture. After 60 minutes of incubation at 450C, the absorption was measured at 820 nm. In order to determine the background absorption, the stop solution was added immediately after adding the glucose 1-phosphate solution in a separate assay. This test was carried out 25 using a 10 pM concentration of the test substance in order to determine the respective inhibition of glycogen phosphorylase a by the test substance in vitro.

In particular, the compounds of formula I exhibit an effect which is from 14- to 32-fold higher than that of comparative example A. 10 The preparation of one example is described in detail below; The remaining compounds of formula I were obtained in an analogous manner: 15 Experimental section: Example 1: a) 2,4-Dichlorobenzoyl isocyanate 20 2,4-Dichlorobenzamide was dissolved in dichloromethane, after which 1.5 eq. of oxalyl chloride were added and the mixture was heated to reflux for 22 16 hours. The reaction mixture was then concentrated under high vacuum and reacted in step b without any further purification. b) 3-[3-(2,4-Dichlorobenzoyl)ureido]-4-methoxybenzoic acid 5 20 g (120 mmol) of 3-amino-4-methoxybenzoic acid were reacted with 36 g (168 mmol) of 2,4-dichlorobenzoyl isocyanate from step a in 400 ml of acetonitrile and reacted at reflux for 2 hours. After the mixture has cooled down to room temperature, the precipitate is filtered off with suction, 10 washed twice with in each case 20 ml of acetonitrile, sucked dry and dried under high vacuum. 44 g (96%) of the desired product are obtained. m.p.: 2900C
