Description

WO 01/55085 PCT/DKO1/00058 1 NEW COMPOUNDS, THEIR PREPARATION AND USE FIELD OF INVENTION 5 The present invention relates to novel compounds, pharmaceutical compositions containing them, methods for preparing the compounds and their use as medicaments. More specifi cally, compounds of the invention can be utilised in the treatment and/or prevention of condi tions mediated by nuclear receptors, in particular the Peroxisome Proliferator-Activated Re 10 ceptors (PPAR). BACKGROUND OF THE INVENTION Coronary artery disease (CAD) is the major cause of death in Type 2 diabetic and metabolic 15 syndrome patients (i.e. patients that fall within the 'deadly quartet' category of impaired glu cose tolerance, insulin resistance, hypertriglyceridaemia and/or obesity). The hypolipidaemic fibrates and antidiabetic thiazolidinediones separately display moderately effective triglyceride-lowering activities although they are neither potent nor efficacious 20 enough to be a single therapy of choice for the dyslipidaemia often observed in Type 2 dia betic or metabolic syndrome patients. The thiazolidinediones also potently lower circulating glucose levels of Type 2 diabetic animal models and humans. However, the fibrate class of compounds are without beneficial effects on glycaemia. Studies on the molecular actions of these compounds indicate that thiazolidinediones and fibrates exert their action by activating 25 distinct transcription factors of the peroxisome proliferator activated receptor (PPAR) family, resulting in increased and decreased expression of specific enzymes and apolipoproteins respectively, both key-players in regulation of plasma triglyceride content. Fibrates, on the one hand, are PPARa activators, acting primarily in the liver. Thiazolidinediones, on the other hand, are high affinity ligands for PPARy acting primarily on adipose tissue. 30 Adipose tissue plays a central role in lipid homeostasis and the maintenance of energy balance in vertebrates. Adipocytes store energy in the form of triglycerides during periods of nutritional affluence and release it in the form of free fatty acids at times of nutritional deprivation. The development of white adipose tissue is the result of a continuous WO 01/55085 PCT/DKO1/00058 2 differentiation process throughout life. Much evidence points to the central role of PPARy activation in initiating and regulating this cell differentiation. Several highly specialised proteins are induced during adipocyte differentiation, most of them being involved in lipid storage and metabolism. The exact link from activation of PPARy to changes in glucose 5 metabolism, most notably a decrease in insulin resistance in muscle, has not yet been clarified. A possible link is via free fatty acids such that activation of PPARy induces Lipoprotein Lipase (LPL), Fatty Acid Transport Protein (FATP) and Acyl-CoA Synthetase (ACS) in adipose tissue but not in muscle tissue. This, in turn, reduces the concentration of free fatty acids in plasma dramatically, and due to substrate competition at the cellular level, 10 skeletal muscle and other tissues with high metabolic rates eventually switch from fatty acid oxidation to glucose oxidation with decreased insulin resistance as a consequence. PPARa is involved in stimulating P-oxidation of fatty acids. In rodents, a PPARa-mediated change in the expression of genes involved in fatty acid metabolism lies at the basis of the 15 phenomenon of peroxisome proliferation, a pleiotropic cellular response, mainly limited to liver and kidney and which can lead to hepatocarcinogenesis in rodents. The phenomenon of peroxisome proliferation is not seen in man. In addition to its role in peroxisome proliferation in rodents, PPARa is also involved in the control of HDL cholesterol levels in rodents and humans. This effect is, at least partially, based on a PPARa-mediated transcrip 20 tional regulation of the major HDL apolipoproteins, apo A-I and apo A-Il. The hypotriglyceridemic action of fibrates and fatty acids also involves PPARa and can be summarised as follows: (1) an increased lipolysis and clearance of remnant particles, due to changes in lipoprotein lipase and apo, C-Ill levels, (II) a stimulation of cellular fatty acid uptake and their subsequent conversion to acyl-CoA derivatives by the induction of fatty acid 25 binding protein and acyl-CoA synthase, (Ill) an induction of fatty acid fl-oxidation pathways, (IV) a reduction in fatty acid and triglyceride synthesis, and finally (V) a decrease in VLDL production. Hence, both enhanced catabolism of triglyceride-rich particles as well as reduced secretion of VLDL particles constitutes mechanisms that contribute to the hypolipidemic effect of fibrates. 30 A number of compounds have been reported to be useful in the treatment of hyperglycemia, hyperlipidemia and hypercholesterolemia (U.S. Pat. 5,306,726, PCT Publications nos.
WO 01/55085 PCT/DKO1/00058 3 W091/19702, WO 95/03038, WO 96/04260, WO 94/13650, WO 94/01420, WO 97/36579, WO 97/25042, WO 95/17394, WO 99/08501, WO 99/19313 and WO 99/16758). SUMMARY OF THE INVENTION 5 Glucose lowering as a single approach does not overcome the macrovascular complications associated with Type 2 diabetes and metabolic syndrome. Novel treatments of Type 2 dia betes and metabolic syndrome must therefore aim at lowering both the overt hypertriglyceri daemia associated with these syndromes as well as alleviation of hyperglycaemia. 10 The clinical activity of fibrates and thiazolidinediones indicates that research for compounds displaying combined PPARa and PPARy activation should lead to the discovery of effica cious glucose and triglyceride lowering drugs that have great potential in the treatment of Type 2 diabetes and the metabolic syndrome (i.e. impaired glucose tolerance, insulin resis 15, tance, hypertriglyceridaemia and/or obesity).

PHARMACOLOGICAL METHODS WO 01/55085 PCT/DKO1/00058 45 In vitro PPAR alpha and PPAR gamma activation activity. Principle 5 The PPAR gene transcription activation assays were based on transient transfection into human HEK293 cells of two plasmids encoding a chimeric test protein and a reporter protein respectively. The chimeric test protein was a fusion of the DNA binding domain (DBD) from the yeast GAL4 transcription factor to the ligand binding domain (LBD) of the human PPAR 10 proteins. The PPAR LBD harbored in addition to the ligand binding pocket also the native activation domain (activating function 2 = AF2) allowing the fusion protein to function as a PPAR ligand dependent transcription factor. The GAL4 DBD will force the fusion protein to bind only to Gai4 enhancers (of which none existed in HEK293 cells). The reporter plasmid contained a Gal4 enhancer driving the expression of the firefly luciferase protein. After trans 15 fection, HEK293 cells expressed the GAL4-DBD-PPAR-LBD fusion protein. The fusion pro tein will in turn bind to the Gal4 enhancer controlling the luciferase expression, and do noth ing in the absence of ligand. Upon addition to the cells of a PPAR ligand, luciferase protein will be produced in amounts corresponding to the activation of the PPAR protein. The amount of luciferase protein is measured by light emission after addition of the appropriate 20 substrate. Methods 25 In vitro transactivation assays. Cell culture and transfection: HEK293 cells were grown in DMEM + 10% FCS. Cells were seeded in 96-well plates the day before transfection to give a confluency of 50-80 % at transfection. A total of 0,8 pg DNA containing 0,64 pg pMlca/yLBD, 0,1 jig pCMVPGal, 0,08 30 pig pGL2Gal4DBD and 0,02 gg pADVANTAGE was transfected per well using FuGene trans fection reagent according to the manufacturers instructions (Roche). Cells were allowed to express protein for 48 h followed by addition of compound.
WO 01/55085 PCT/DKO1/00058 46 Plasmids: Human PPAR a and y was obtained by PCR amplification using cDNA synthesized by reverse transcription of mRNA from liver and adipose tissue respectively. Amplified cDNAs were cloned into pCR2.1 and sequenced. The ligand binding domain (LBD) of each PPAR isoform was generated by PCR (PPARa: aa 167 - C-terminus; PPARy: aa 165 - C 5 terminus) and fused to the DNA binding domain (DBD) of the yeast transcription factor GAL4 by subcloning fragments in frame into the vector pM1 generating the plasmids pMlaLBD and pMlyLBD. Ensuing fusions were verified by sequencing. The reporter was constructed by inserting an oligonucleotide encoding five repeats of the GAL4 recognition sequence (5 x CGGAGTACTGTCCTCCG(AG)) into the vector pGL2 promotor (Promega) generating the 10 plasmid pGL2(GAL4). pCMVpGaI was purchased from Clontech and pADVANTAGE was purchased from Promega. Luciferase assay: Medium including test compound was aspirated and 100 pl PBS incl. 1mM Mg++ and Ca++ was added to each well. The luciferase assay was performed using the Lu 15 cLite kit according to the manufacturers instructions (Packard Instruments). Light emission was quantified by counting SPC mode on a Packard Instruments top-counter. To measure p galactosidase activity 25 id supernatant from each transfection lysate was transferred to a new microplate. p-galactosidase assays were performed in the microwell plates. using a kit from Promega and read in a microplate reader. The p-galactosidase data were used to nor 20 malize (transfection efficiency, cell growth etc.) the luciferase data. Compounds: All compounds were dissolved in DMSO and diluted 1:1000 upon addition to the cells. Compounds were tested in quadruple in five concentrations ranging form 0.01 to 30 pM. Cells were treated with compound for 24 h followed by luciferase assay. Each compound 25 was tested in three separate experiments. EC 5 0 values were calculated via non-linear regres sion using GraphPad PRISM 3.02 (GraphPad Software, San Diego, CA).The results were expressed as means. 30 WO 01/55085 PCT/DKO1/00058 47 Table 1.

It should be understood that any suitable combination of the compounds according to the in 20 vention with one or more of the above-mentioned compounds and optionally one or more-fur ther pharmacologically active substances are considered to be within the scope of the pre sent invention. Pharmaceutical compositions containing a compound of the present invention may be prepared 25 by conventional techniques, e.g. as described in Remington: The Science and Practise of Pharmacy, 1 9th Ed., 1995. The compositions may appear in conventional forms, for example capsules, tablets, aerosols, solutions, suspensions or topical applications. Typical compositions include a compound of formula I or a pharmaceutically acceptable acid 30 addition salt thereof, associated with a pharmaceutically acceptable excipient which may be a carrier or a diluent or be diluted by a carrier, or enclosed within a carrier which can be in the form of a capsule, sachet, paper or other container. In making the compositions, conventional techniques for the preparation of pharmaceutical compositions may be used. For example, the active compound will usually be mixed with a carrier, or diluted by a carrier, WO 01/55085 PCT/DKO1/00058 51 or enclosed within a carrier which may be in the form of a ampoule, capsule, sachet, paper, or other container. When the carrier serves as a diluent, it may be solid, semi-solid, or liquid material which acts as a vehicle, excipient, or medium for the active compound. The active compound can be adsorbed on a granular solid container for example in a sachet. Some 5 examples of suitable carriers are water, salt solutions, alcohols, polyethylene glycols, polyhydroxyethoxylated castor oil, peanut oil, olive oil, gelatine, lactose, terra alba, sucrose, cyclodextrin, amylose, magnesium stearate, talc, gelatin, agar, pectin, acacia, stearic acid or lower alkyl ethers of cellulose, silicic acid, fatty acids, fatty acid amines, fatty acid monoglycerides and diglycerides, pentaerythritol fatty acid esters, polyoxyethylene, 10 hydroxymethylcellulose and polyvinylpyrrolidone. Similarly, the carrier or diluent may include any sustained release material known in the art, such as glyceryl monostearate or glyceryl distearate, alone or mixed with a wax. The formulations may also include wetting agents, emulsifying and suspending agents, preserving agents, sweetening agents or flavouring agents. The formulations of the invention may be formulated so as to provide quick, 15 sustained, or delayed release of the active ingredient after administration to the patient by employing procedures well known in the art. The pharmaceutical compositions can be sterilized and mixed, if desired, with auxiliary agents, emulsifiers, salt for influencing osmotic pressure, buffers and/or colouring sub 20 stances and the like, which do not deleteriously react with the active compounds. The route of administration may be any route, which effectively transports the active com pound to the appropriate or desired site of action, such as oral, nasal, pulmonary, transdermal orparenteral e.g. rectal, depot, subcutaneous, intravenous, intraurethral, intramuscular, in 25 tranasal,.ophthalmic solution or an ointment, the oral route being preferred. If a solid carrier is used for oral administration, the preparation may be tabletted, placed in a hard gelatin capsule in powder or pellet form or it can be in the form of a troche or lozenge. If a liquid carrier is used, the preparation may be in the form of a syrup, emulsion, soft gelatin 30 capsule or sterile injectable liquid such as an aqueous or non-aqueous liquid suspension or solution. For nasal administration, the preparation may contain a compound of formula I dissolved or suspended in a liquid carrier, in particular an aqueous carrier, for aerosol application. The carrier WO 01/55085 PCT/DKO1/00058 52 may contain additives such as solubilizing agents, e.g. propylene glycol, surfactants, absorption enhancers such as lecithin (phosphatidylcholine) or cyclodextrin, or preservatives such as parabenes. 5 For parenteral application, particularly suitable are injectable solutions or suspensions, pref erably aqueous solutions with the active compound dissolved in polyhydroxylated castor oil. Tablets, dragees, or capsules having talc and/or a carbohydrate carrier or binder or the like are particularly suitable for oral application. Preferable carriers for tablets, dragees, or cap 10 sules include lactose, corn starch, and/or potato starch. A syrup or elixir can be used in cases where a sweetened vehicle can be employed. A typical tablet which may be prepared by conventional tabletting techniques may contain: 15 Core: Active compound (as free compound or salt thereof) 5 mg Colloidal silicon dioxide (Aerosil) 1.5 mg Cellulose, microcryst. (Avicel) 70 mg Modified cellulose gum (Ac-Di-Sol) 7.5 mg 20 Magnesium stearate Ad. Coating: HPMC approx. 9 mg *Mywaceft 9-40 T approx. 0.9 mg 25 *Acylated monoglyceride used as plasticizer for film coating. The compounds of the invention may be administered to a mammal, especially a human in need of such treatment, prevention, elimination, alleviation or amelioration of diseases 30 related to the regulation of blood sugar. Such mammals include also animals, both domestic animals, e.g. household pets, and non domestic animals such as wildlife.
WO 01/55085 PCT/DKO1/00058 53 The compounds of the invention are effective over a wide dosage range. For example, in the treatment of adult humans, dosages from about 0.05 to about 100 mg, preferably from about 0.1 to about 100 mg, per day may be used. A most preferable dosage is about 0.1 mg to about 70 mg per day. In choosing a regimen for patients it may frequently be necessary to 5 begin with a dosage of from about 2 to about 70 mg per day and when the condition is under control to reduce the dosage as low as from about 0.1 to about 10 mg per day. The exact dosage will depend upon the mode of administration, on the therapy desired, form in which administered, the subject to be treated and the body weight of the subject to be treated, and the preference and experience of the physician or veterinarian in charge. 10 Generally, the compounds of the present invention are dispensed in unit dosage form comprising from about 0.1 to about 100 mg of active ingredient together with a pharmaceutically acceptable carrier per unit dosage. 15 Usually, dosage forms suitable for oral, nasal, pulmonary or transdermal administration comprise from about 0.001 mg to about 100 mg, preferably from about 0.01 mg to about 50 mg of the compounds of formula I admixed with a pharmaceutically acceptable carrier or diluent. Any novel feature or combination of features described herein is considered essential to this 20 invention. EXAMPLES The process for preparing compounds of formula I, and preparations containing them, is 25 further illustrated in the following examples, which however, are not to be construed as limiting. The structures of the compounds are confirmed by either elemental analysis (MA) nuclear magnetic resonance (NMR) or mass spectrometry (MS). NMR shifts (8) are given in parts per million (ppm) and only selected peaks are given. Mp is melting point and is given in 0 C. Col 30 umn chromatography was carried out using the technique described by W.C. Still et al, J. Org. Chem. 1978, 43, 2923-2925 on Merck silica gel 60 (Art 9385). Compounds used as starting materials are either known compounds or compounds which can readily be prepared by methods known per se.
