The daily dose is generally in the range of 0.3 mg to 100 mg (typically 3 mg to 50 mg) per day and per kilogram of body weight, eg, 3-10 mg / kg / day. An intravenous dose can be, for example, in the range of 0.3 mg to 1.0 mg / kg, which can be administered, suitably, as an infusion of 10 ng to 100 ng per kilogram per minute. Infusion solutions suitable for these purposes may contain, for example, 0.1 ng to 10 mg, typically 1 ng to 10 mg, per milliliter. The individual doses may contain, for example, from 1 mg to 10 g of the active ingredient. Thus, ampoules for injections may contain, for example, 1 mg to 100 mg, and single dose formulations that can be administered orally, such as, for example, tablets or capsules, may contain, for example, 0.05. to 1,000 mg, typically from 0.5 to 600 mg. In the case of therapy of the conditions mentioned above, the compounds of formula I or II can be used as the compound itself, but preferably they are in the form of a pharmaceutical composition with an acceptable carrier. Of course, the vehicle must be acceptable in the sense that it is compatible with the other ingredients of the composition and that it is not detrimental to the patient's health. The carrier may be a solid or a liquid or both and preferably is 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. Other active substances can also be present from a pharmaceutical point of view, which include other compounds of the invention. The pharmaceutical compositions of the invention can be produced by one of the known pharmaceutical methods, consisting essentially of mixing the ingredients with vehicles and / or excipients acceptable from a pharmacological point of view. Pharmaceutical compositions of the invention are those, suitable for oral, rectal, topical, peroral for example, sublingual) and parenteral (for example subcutaneous, intramuscular, intradermal or intravenous) administration, although the most appropriate administration route depends in each individual case of the nature and severity of the condition to be treated and the nature of the compound of formula I or II used in each case. Coated formulations and slow release coated formulations are also within the scope of the invention. Preference is given to formulations resistant to acids and gastric juices. Suitable coatings resistant to gastric juices comprise cellulose acetate phthalate, poly (vinyl acetate phthalate), hydroxypropylmethylcellulose phthalate and anionic polymers of methacrylic acid and methyl methacrylate. Pharmaceutical compounds suitable for oral administration may be in the form of individual units, such as, for example, capsules, tablets that are sucked or compressed, each of which contains a defined amount of the compound of formula I or II; as powders or granules; as a solution or suspension in an aqueous or non-aqueous liquid; or as an oil in water or water in oil emulsion. As mentioned above, these compositions can be prepared by any suitable pharmaceutical method which includes a step in which the active ingredient and the vehicle (which can consist of one or more additional ingredients) are brought into contact. Generally, the compositions are produced by a uniform and homogeneous mixture of the active ingredient with a liquid and / or finely divided solid carrier, after which the product is molded if necessary. Thus, for example, a tablet can be produced by compressing or molding a powder or granules of the compound, when appropriate, with one or more additional ingredients. Pressed tablets can be produced by pressing the soft flowing compound, for example, from a powder or granules, where appropriate mixed with a binder, inert diluent and / or one or more surfactants / dispersants in a suitable machine . The molded tablets can be produced by molding the compound, which is in powder form and moistened with an inert liquid diluent, in a suitable machine. Pharmaceutical compositions which are suitable for peroral (sublingual) administration comprise sucking tablets containing a compound of formula I or II with a flavoring, usually sucrose and gum arabic or tragacanth, and lozenges comprising the compound in an inert base such as gelatin and glycerol or sucrose and gum arabic. Pharmaceutical compositions suitable for parenteral administration preferably comprise sterile aqueous preparations of a compound of formula I or II, which are preferably isotonic with the blood of the recipient. These preparations are preferably administered intravenously, although they can also be administered by subcutaneous, intramuscular or intradermal injection. Preferably, these preparations can be produced by mixing the compound with water and sterilizing the resulting solution and making it isotonic with the blood. Generally, the injectable compositions of the invention contain from 0.1 to 5% by weight of the active compound. Pharmaceutical compositions suitable for rectal administration are preferably in the form of single dose suppositories. These can be produced by mixing a compound of the formula I or II with one or more conventional solid carriers, for example, cocoa butter, and by molding the resulting mixture. Pharmaceutical compositions suitable for topical use in the skin are preferably in the form of ointment, cream, lotion, paste, spray, aerosol or oil. Vehicles that can be used are petrolatum, lanolin, polyethylene glycols, alcohols and combinations of two or more of these substances. Generally, the active ingredient is 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. Pharmaceutical compositions suitable for transdermal uses may be in the form of individual patches that are suitable for close contact with the epidermis of the patient for a long period of time. Said patches suitably contain the active ingredient in an aqueous solution which is buffered when appropriate, dissolved and / or dispersed in an adhesive or dispersed in a polymer. A suitable concentration of the active ingredient is about 1% to 35%, preferably about 3% to 15%. A particular possibility is that the active ingredient is released by electrotransport or iontophoresis as described, for example, in Pharmaceutical Research, 2 (6): 318 (1986). The compounds of formulas I and II are characterized by having favorable effects on metabolic disorders. They have a beneficial effect on the metabolism of lipids and sugars, in particular, they lower the level of triglycerides and are suitable for the prevention and treatment of type II diabetes and arteriosclerosis and the various sequelae of these.
Combinations with other medications The compounds of the invention can be administered alone or in combination with one or more additional substances active from a pharmacological point of view which have, for example, favorable effects on alterations or metabolic disorders which are frequently associated with them. Examples of these medications are 1. drugs that lower blood glucose, antidiabetics, 2. active ingredients for the treatment of dyslipidemias, 3. anti-atherosclerotic drugs, 4. anti-obesity agents, 5. anti-inflammatory active ingredients 6. active ingredients for the treatment of malignant tumors 7. active ingredients antithrombotic 8. active ingredients for the treatment of high blood pressure 9. active ingredients for the treatment of heart failure and 10. active ingredients for the treatment and / or prevention of complications caused by diabetes or associated with diabetes. They can be combined with the compounds of the invention of the formula I or II, in particular, in order to achieve a synergistic improvement in the effect. Administration of the active ingredient combination can take place by separate administration to the patient of the active ingredients or in the form of combination products in which a plurality of active ingredients are present in a pharmaceutical preparation.

It should be appreciated that each suitable combination of the compounds of the invention with one or more of the compounds mentioned above and, optionally, with one or more other pharmaceutically active substances, is considered to be in the protection conferred by the present invention. The activity of the compounds of the invention of formulas I or II was tested in the following enzyme assay system: Substrate preparation: Preparation of the substrate NAG (NBD monoacyl glyceride): 6 mg of phosphatidylcholine and 6 mg of phosphatidylinositol were dissolved in 1 ml of chloroform, each. 10 mg of NAG was dissolved in 1 ml of chloroform. Two parts of the phosphatidylinositol solution (eg, 83.5 μl) and a portion of the phosphatidylcholine solution (eg, 41.5 μl) and 100 μl of the NAG solution in plastic scintillation containers were co-pipetted. (final concentration in the assay: 0.0375 mg phospholipid / ml, 0.05 mg / NAG / ml). Chloroform (total volume 225 μl) was completely removed by passing a stream of N2 over it. The dried substrate can be stored at 4 ° C for up to 3 days. To prepare the phospholipid vesicles / micelles with NAG intercalated (on the day of the assay), the dried substrate was dissolved in 20 ml of the assay buffer (25 mM Tris / HCl, pH 7.4, 150 mM NaCl) and with two ultrasound treatments with an ultrasonic probe (Branson Sonifier Type II, standard microtip): 1st treatment adjustment 2, 2 x 1 min, in between 1 min on ice every time; 2nd treatment adjustment 4, 2 x 1 min, in between 1 min on ice every time. During this procedure, the color of the substrate solution changes from yellow (maximum extinction 481 nm) to red (maximum extinction 550 nm) allowing the intercalation of NAG between the phospholipid molecules in the vesicles / micelles. Before being used as a substrate (in the next 2 h), the solution is incubated on ice for 15 min.
Indirect NAG test: The assay was carried out in 1.5 ml Eppendorf containers or in 96-well plates at 30 ° C for 60 min. In order to find inhibitors of HSL, 10 μl of the substance to be tested was introduced into the assay buffer (25 mM Tris / HCl, pH 7.4, 150 mM NaCl) in the presence of 16.6% DMSO. 180 μl of the substrate solution (20 μg / ml phosphatidylcholine, 10 μg / ml phosphatidylinositol, 50 μg / ml NAG in the assay buffer) was added. After preincubation at 30 ° C for 15 min, 20 μl of the enzyme solution was pipetted into the assay buffer (diluted 1 to 4 times), and the extinction was immediately measured at 480 nm in a photometer cuvette (cuvette). 0.5 ml) or in a microplate reader. After incubation at 30 ° C for 60 min, the extinction was measured again. The increase in the extinction at 480 nm is a measure of the enzymatic activity. Under standard conditions, 20 μg of partially purified HSL results in a change of 0.4 = 4,000 arb units. in the extinction.
Direct NAG test: As an alternative to the measurement of the change in the extinction of the substrate solution, the products of the HSL reaction were investigated by phase separation / thin layer chromatography. For this purpose, 1.3 ml of methanol / chloroform / heptane (10: 9: 7) and then 0.4 ml of 0.1 M NaOH were added to the incubation mixture (total volume 200 μl, see the Indirect NAG) in 2 ml Eppendorf containers. After mixing vigorously (10 s), phase separation was initiated by centrifugation (800 x g, 20 min, room temperature). Equivalent volumes (e.g., 0.4 ml) of the upper aqueous phase were taken, and the extinction was determined at 481 nm in a photometer. In the case of thin layer chromatography, the aqueous phase was dried (SpeedVac) and dissolved in 50 μl of tetrahydrofuran. 5 μl samples were loaded onto Si-60 silica gel plates (Merck). Chromatography was carried out with 78 ml of diethyl ether / 22 ml of petroleum ether / 1 ml of glacial acetic acid as the mobile phase. The amount of NBD-fluorescent fatty acid released was determined by Phosphorimaging (Molecular Dynamics, Storm 840 and ImageQuant Software) at an excitation wavelength of 460 nm and at an emission wavelength of 540-560 nm.
Preparation of the enzyme: Preparation of partially purified HSL: Rat adipose cells are obtained from epidimal adipose tissue of untreated male rats (Wistar, 220-250 g) by treatment with collagenase according to published methods (for example, S. Nilsson et al. , Anal, Biochem, 158, 1986, 399-407; G. Fredrikson et al., J. Biol. Chem. 256, 1981, 6311-6320; H. Tornquist et al., J. Biol. Chem. 251, 1976, 813-819). The fat cells of 10 rats are washed three times by flotation with 50 ml of homogenization buffer (25 ml Tris / HCl, pH 7.4, 0.25 M sucrose, 1 mM ETDA, 1 mM DTT, 10 μg / ml leupeptin , 10 μg / ml antipain, 20 μg / ml pepstatin) each time and finally resuspend in 10 ml of homogenization buffer. The fat cells are homogenized in a Teflon and glass homogenizer (Braun-Melsungen) by 10 strokes at 1,500 rpm at 15 ° C. The homogenate is centrifuged (SM24 Sorvall tubes, 5,000 rpm, 10 min, 4 ° C). The subnatant between the fat layer in the upper part and the sediment is collected and the centrifugation is repeated. The resulting subnatant is centrifuged again (SM24 Sorvall tubes, 20,000 rpm, 45 min, 4 ° C). The subnatant is collected and 1 g of Sepharose-heparin is added (Pharmacia-Biotech, CL-6B, washed 5x with 25 mM Tris / HCl, pH 7.4, 150 mM NaCl). After incubating at 4 ° C for 60 min (with shaking at 15 min intervals), the mixture is centrifuged (SM24 Sorvall tubes, 3,000 rpm, 10 min, 4 ° C). The supernatant is adjusted to pH 5.2 by the addition of glacial acetic acid and incubated at 4 ° C for 30 min. The precipitates are collected by centrifugation (Sorvall SS34, 12,000 rpm, 10 min, 4 ° C) and resuspended in 2.5 ml of 20 mM Tris / HCl, pH 7.0, 1 mM EDTA, 65 mM NaCl, 13% sucrose, 1 mM DTT, 10 μg / ml leupeptin / pepstatin / antipain. The suspension is dialyzed against 25 M Tris / HCl, pH 7.4, 50% glycerol, 1 mM DTT, 10 μg / ml leupeptin, pepstatin, antipain at 4 ° C overnight and then loaded onto a column of hydroxyapatite (0.1 g per 1 ml of suspension, equilibrated with 10 mM potassium phosphate, pH 7.0, 30% glycerol, 1 mM DTT). The column is washed with four volumes of equilibration buffer at a flow rate of 20 to 30 ml / h. The HSL is eluted with a volume of equilibration buffer containing 0.5 M potassium phosphate and then dialyzed (see above) and concentrated 5 to 10 times by ultrafiltration (Amicon Diaflo PM 10 Filter) at 4 ° C. Partially purified HSL can be stored at -70 ° C for 4 to 6 weeks.
Test: In order to prepare the substrate, 25-50 μCi of [3H] trioleoylglycerol (in toluene), 6.8 μmol of unlabeled trioleoylglycerol and 0.6 mg of phospholipids (phosphatidylcholine / phosphatidylinositol 3: 1 w / v) are mixed. , they are dried with N2 and then resuspended in 2 ml of 0.1 M KPi (pH 7.0) by means of ultrasonic treatment (Branson 250, microtip, adjustment 1-2, 2 x 1 min with an interval of 1 min) . After adding 1 ml of KPi and a new ultrasound treatment (4 x 30 sec on ice at 30 s intervals), 1 ml of 20% BSA is added > (in KPi) (final concentration of 1.7 mM trileoylglycerol). For this reaction, 100 μl of the substrate solution is pipetted into 100 μl of the HSL solution (HSL prepared as described above, diluted in 20 mM KPi, pH 7.0, 1 mM EDTA, 1 mM DTT, 0.02% BSA, 20 μg / ml pepstatin, 10 μg / ml leupeptin) and incubated at 37 ° C for 30 min. After the addition of 3.25 ml of methanol / chloroform / heptane (10: 9: 7) and 1.05 ml of 0.1 M K2CO3, 0.1 M boric acid (pH 10.5) is mixed thoroughly and centrifuged (800 xg, 20 min). After separation of the phases, an equivalent of the upper phase (1 ml) is collected and the radioactivity is determined by liquid scintillation determination.
Evaluation: Normally, the substances are tested in four independent mixtures. The inhibition of the enzymatic activity of HSL by a test substance is determined by comparison with a control reaction without inhibition. The IC50 is calculated from a representation of the inhibition with min. 10 concentrations of the substance to be tested. The GRAPHIT, Elsevier-BIOSOFT software package is used to analyze the data. The compounds of Examples 1 to 103 show inhibitions in the IC50 range of 1 nM-1 μM in this assay. The compounds of the invention of the general formulas I or II are prepared by methods known per se, for example by acylation of III indazoles substituted or unsubstituted with carbamoyl chlorides (method A), or in two steps by the reaction of indazoles III with phosphogen or equivalents such as trichloromethyl chlorocarbonate or dithrichloromethyl carbonate and further reaction of the resulting indazolecarbonyl chloride with amines or anilines (method B). In the case of the compounds in which R3 is hydrogen, the indazoles III can also be reacted with the appropriate isocyanates R2-N = C = O.
III IV As acids are normally released in these reactions, it is advisable to add bases such as pyridine, triethylamine, sodium hydroxide solution or alkali metal carbonates to accelerate them. The reactions can be carried out in wide temperature ranges. It has been found that it is usually advantageous to operate at 0 ° C to the boiling point of the solvent used. Examples of solvents used are methylene chloride, THF, DMF, toluene, ethyl acetate, n-heptane, dioxane, diethyl ether or pyridine. If anhydrous conditions are used, it has been shown that strong bases such as lithium hydride, sodium hydride or potassium t-butoxide in aprotic solvents such as THF or DMF are also suitable. The indazoles used as starting compounds III, or the corresponding aza-substituted derivatives, are commercially available or can be prepared by processes known from the literature (for example, L. Baiocchi, G. Corsi Syntesis (1978), 633-648, I. Sekikawa et al., J. Het. Chem. (1973), 931-932).
