The pharmacological activity of the substances according to the invention was assessed using the following test:

CETP Inhibition Test

Preparation of CETP

CETP is obtained in partially purified form from human plasma by differential centrifugation and column chromatography and used for the test. For this purpose, human plasma is adjusted to a density of 1.21 g per ml using NaBr and centrifuged at 50,000 rpm at 4° C. for 18 h. The bottom fraction (d>1.21 g/ml) is applied to a Sephadex®Phenyl-Sepharose 4B (Pharmacia) column, washed with 0.15 mM NaCl/0.001 M TrisHCl pH 7.4 and subsequently eluted using dist. water. The CETP-active fractions are pooled, dialysed against 50 mM Na-acetate pH 4.5 and applied to a CM-Sepharose® (Pharmacia) column. Elution is subsequently carried out using a linear gradient (0-1 M NaCl). The pooled CETP fractions are dialysed against 10 mM TrisHCl pH 7.4 and subsequently purified further by chromatography over a Mono Q® column (Pharmacia).

Preparation of Radioactively Labelled HDL

50 ml of fresh human EDTA plasma is adjusted to a density of 1.12 using NaBr and centrifuged at 4° C. in a Ty 65 rotor at 50,000 rpm for 18 h. The upper phase is used to obtain cold LDL. The lower phase is dialysed against 3*4 l of PDB buffer (10 mM Tris/HCl pH 7.4, 0.15 mM NaCl, 1 mM EDTA, 0.02% NaN 3 ). Per 10 ml volume of retained material, 20 μl of 3 H-cholesterol (Dupont NET-725; 1 μCi/ml, dissolved in ethanol!) are subsequently added, and the mixture is incubated at 37° C. under N 2 for 72 h.

The mixture is then adjusted to a density of 1.21 using NaBr and centrifuged in a Ty 65 rotor at 20° C. and 50,000 rpm for 18 h. The upper phase is collected and the lipoprotein fractions are purified by gradient centrifugation. To this end, the isolated labelled lipoprotein fraction is adjusted to a density of 1.26 using NaBr. In each case 4 ml of this solution are covered in centrifuge tubes (SW 40 rotor) with 4 ml of a solution of a density of 1.21 and 4.5 ml of a solution of 1.063 (density solutions of PDB buffer and NaBr), and the tubes are subsequently centrifuged in an SW 40 rotor at 38,000 rpm and 20° C. for 24 h. The intermediate layer which is found between a density of 1.063 and a density of 1.21 and which contains the labelled HDL is dialysed against 3*100 volume of PDB buffer at 4° C.

The retained material contains radioactively labelled 3 H-CE-HDL, which is used for the test adjusted to approximately 5×10 6 cmp.

CETP Test

To assess the CETP activity, the transfer of 3 H-cholesterol ester from human HD-lipoproteins to biotinylated LD-lipoproteins is measured.

The reaction is terminated by addition of Streptavidin-SPA® beads (Amersham) and the transferred radioactivity is directly measured in a liquid scintillation counter.

In the assay mixture, 10 μl of HDL- 3 H-cholesterol ester (˜50,000 cpm) with 10 μl of Biotin-LDL (Amersham) in 50 mM Hepes/0.15 m NaCl/0.1% bovine serum albumin/0.05% NaN 3 pH 7.4 are incubated with 10 μl of CETP (1 mg/ml) and 3 μl of a solution of the substance to be tested (dissolved in 10% DMSO/1% BSA) at 37° C. for 18 h. 200 μl of the SPA streptavidin bead solution (TRKQ 7005) are subsequently added, the mixture is incubated with shaking for another 1 h and subsequently measured in a scintillation counter. The controls used are corresponding incubations with 10 μl of buffer, 10 μl of CETP at 4° C. and 10 μl of CETP at 37° C.

The activity which is transferred in the control experiments with CETP at 37° C. is taken to be 100% transfer. The substance concentration at which this transfer is reduced by half is stated as the IC 50 value.

In Table A below, the IC 50 values (mol/l) for CETP inhibitors are given:

Ex vivo Activity of the Compounds According to the Invention

Syrian gold hamsters, which have been bred in our own laboratory, are anaesthetized after 24 hours of fasting (0.8 mg/kg of atropine, 0.8 mg/kg of Ketavet® s.c., 30′ later 50 mg/kg of nembutal i.p.). The jugular vein is subsequently exposed and cannulated. The test substance is dissolved in a suitable solvent (usually adalate placebo solution: 60 g of glycerol, 100 ml of H 2 O, ad 1000 ml PEG-400) and administered to the animals via a PE catheter, which is introduced into the jugular vein. The same volume of solvent without test substance is administered to the control animals. The vein is subsequently tied off and the wound is closed.

The test substances can also be administered p.o. by dissolving the substances in DMSO and suspending them in 0.5% tylose and administering them using a pharyngeal tube. Identical volumes of solvent without test substance are administered to the control animals.

At different intervals—up to 24 hours after the administration—blood samples are taken from the animals by puncture of the retro-orbital venous plexus (approximately 250 μl). Coagulation is completed by incubation at 4° C. overnight, and the samples are subsequently centrifuged at 6000×g for 10 minutes. The CETP activity is determined in the resulting serum using the modified CETP test. The transfer of 3 H-cholesterol ester from HD-lipoproteins to biotinylated LD-lipoproteins is measured as described above for the CETP test.

The reaction is terminated by addition of Streptavidin-SPA® beads (Amersham), and the transferred radioactivity is directly determined in a liquid scintillation counter.

The test protocol is carried out as described under “CETP test”. However, to test the sera, 10 μl of CETP are replaced by 10 μl of the appropriate serum samples. Corresponding incubations of sera of untreated animals serve as controls.

The activity that is transferred in the control experiments using control sera is classified as 100% transfer. The substance concentration at which this transfer is reduced by half is stated as the ED 50 value.

In vivo Activity of the Compounds According to the Invention

In experiments for assessing the oral activity on lipoproteins and triglycerides, test substance, dissolved in DMSO and suspended in 0.5% tylose, is administered perorally by means of a pharyngeal tube to Syrian gold hamsters which have been bred in our own laboratory. To determine the CETP activity, blood samples (approximately 250 μl) are taken by retro-orbital puncture prior to the start of the experiment. The test substances are subsequently administered perorally using a pharyngeal tube. Identical volumes of solvent without test substance are administered to the control animals. Subsequently, the animals have to fast and at different intervals—up to 24 hours after the administration of the substances—blood samples are taken by puncture of the retro-orbital venous plexus.

Coagulation is completed by incubation at 4° C. overnight, and the samples are subsequently centrifuged at 6000×g for 10 minutes. The content of cholesterol and triglycerides in the resulting serum is assessed using modified commercially available enzyme tests (cholesterol enzymatic 14366 Merck, triglycerides 14364 Merck). Serum is diluted in a suitable manner with normal saline solution.

100 μl of serum dilution and 100 μl of test substance are transferred into 96-well-plates and incubated at room temperature for 10 minutes. The optical density is subsequently determined at a wavelength of 492 nm using an automatic plate reader.

The triglyceride and cholesterol concentrations of the samples are determined with the aid of a standard curve measured in parallel.

The determination of the HDL-cholesterol content is carried out after precipitation of the ApoB-containing lipoproteins using a reagent mixture (Sigma 352-4 HDL cholesterol reagent) in accordance with the instructions of the manufacturer.

In vivo Activity in Transgenic hCETP Mice

The substances to be tested were administered to transgenic mice, which were bred in our own laboratory (Dinchuck, Hart, Gonzalez, Karmann, Schmidt, Wirak; BBA (1995), 1295, 301), via the feed. Prior to the beginning of the experiment, blood samples were taken retro-orbitally from the mice to determine cholesterol and triglycerides in the serum. The serum was obtained as described above for hamsters by incubation at 4° C. overnight and subsequent centrifugation at 6000×g. After one week, blood samples were again taken from the mice to determine lipoproteins and triglycerides. The change of the measured parameters are expressed as a change in percent based on the initial value.

The invention furthermore relates to the combination of substituted tetrahydro-naphthalenes of the general formula (I) with a glucosidase and/or amylase inhibitor for the treatment of familial hyperlipidaemias, of obesity (adipositas) and of diabetes mellitus. Glucosidase and/or amylase inhibitors in the context of the present invention are, for example, acarbose, adiposine, voglibose, miglitol, emiglitate, MDL-25637, camiglibose (MDL-73945), tendamistate, AI-3688, trestatin, pradimicin-Q and salbostatin.

Preference is given to the combination of acarbose, miglitol, emiglitate or voglibose with one of the abovementioned compounds of the general formula (I) according to the invention.

Furthermore, the compounds according to the invention can be combined with cholesterol-lowering vastatines or ApoB-lowering principles, in order to treat dyslipidaemias, combined hyperlipidaemias, hypercholesterolaemias or hypertriglyceridaemias.

The abovementioned combinations can also be used for primary or secondary prevention of coronary heart diseases (for example myocardial infarction).

Vastatines in the context of the present invention are, for example, lovastatin, simvastatin, pravastatin, fluvastatin, atorvastatin and cerivastatin. ApoB-lowering agents are, for example, MTP inhibitors.

Preference is given to the combination of cerivastatin or ApoB inhibitors with one of the abovementioned compounds of the general formulae (I) and (Ia) according to the invention.

The novel active compounds can be converted in a known manner into the customary formulations, such as tablets, coated tablets, pills, granules, aerosols, syrups, emulsions, suspensions and solutions, using inert, non-toxic, pharmaceutically suitable carriers or solvents. In this case the therapeutically active compound should in each case be present in a concentration from approximately 0.5 to 90% by weight of the total mixture, i.e. in amounts which are sufficient in order to achieve the dosage range indicated.

The formulations are prepared, for example, by extending the active compound using solvents and/or carriers, if appropriate using emulsifiers and/or dispersants, it optionally being possible, for example, to use organic solvents as auxiliary solvents if the diluent used is water.

Administration is carried out in a customary manner, intravenously, orally, parenterally or perlingually, in particular orally.

In the case of parenteral administration, solutions of the active compound can be used by employing suitable liquid carrier materials.

In general, it has proved advantageous, in the case of intravenous administration, to administer amounts from approximately 0.01 to 1 mg/kg, preferably approximately 0.01 to 0.5 mg/kg, of body weight to achieve effective results, and in the case of oral administration the dosage is approximately 0.01 to 20 mg/kg, preferably 0.1 to 10 mg/kg, of body weight.

In spite of this, if appropriate it may be necessary to depart from the amounts mentioned, namely depending on the body weight or on the type of administration route, on individual reaction towards the medicament, the manner of its formulation and the time at or interval during which administration takes place. Thus, in some cases it may be adequate to manage with less than the abovementioned minimum amounts, while in other cases the upper limit mentioned has to be exceeded. In the case of the administration of relatively large amounts, it may be advisable to divide these into several individual doses over the course of the day.
