Abstract

Novel salicylic anilides are chemical uncouplers useful e.g. for the treatment of obesity.

Description

NOVELTY SALICIICIAS ANILIDAS FIELD OF THE INVENTION The present invention relates to novel derivatives of salicylic anuide. The derivatives are effective chemical uncoupling and therefore are useful in the treatment, for example, of obesity.
BACKGROUND OF THE INVENTION Obesity is a well-known risk factor for the development of many very common diseases such as atherosclerosis, hypertension, type 2 diabetes, diabetes (non-insulin-dependent mellitus (NIDDM)), dyslipidemia, coronary heart disease and osteoarthritis and various cancers. It also causes considerable problems due to reduced mobility and a diminished quality of life. The number of obese people and the incidence of these diseases increases throughout the industrialized world. The term obesity indicates an excess of adipose tissue. In this context, obesity is best considered as any degree of excess of adiposity that produces a risk to health. The limit between normal and obese individuals can only be approximate, but the risk to health generated by obesity is probably continuous, as adiposity increases. In the context of Ref: 172567 present invention, persons with a body mass index (BMI) = body weight in kilograms divided by the square of their height in meters) greater than 25 are considered obese . Even moderate obesity increases the risk of premature death and diseases such as diabetes, dyslipidemia, hypertension, atherosclerosis, gallbladder disease and certain types of cancer. In the industrialized Western world the prevalence of obesity has increased significantly in recent decades. Due to the high prevalence of obesity and its consequences on health, its prevention and treatment should be a high priority for public health. With the exception of exercise, diet and limitation in foods, which is not feasible for a large number of patients, there is currently no convincing treatment to effectively and acceptable reduce body weight. However, not only in view of the considerable problems directly related to obesity such as those described above, but also due to the important effect of obesity as a risk factor in serious and even deadly and common diseases, they are important to find pharmaceutical compounds that are useful for the prevention and / or treatment of obesity.
When the energy intake exceeds the expenditure, the excess calories are stored predominantly in the adipose tissue and if this positive net balance is prolonged, it results in obesity, that is, there are components for weight balance and an anomaly. On either side (ingestion or expense) can lead to obesity. This process can be counteracted by increasing the energy expenditure (for example through exercise) or by decreasing the energy intake (for example with diets). The pharmacological treatment to date consists solely of Sibutramine (which acts on serotonergic mechanisms, Abbott) and Orlistat (which reduces the uptake of fat from the intestine, Roche Pharm), neither reduces body weight effectively or acceptably. Therefore, there is a need for pharmaceutical compounds which may be useful for the prevention and / or treatment of obesity, for example by increasing energy expenditure or by decreasing energy intake. One way to increase energy expenditure is by increasing the metabolic rate. Oxidative phosphorylation in the mitochondria, the energy of glucose metabolism and the oxidation of free fatty acids is used to activate the phosphorylation of ADP to ATP. When NADH and FADH2 are formed in the TCA cycle, they are oxidized back to NAD + and FAD, respectively, and protons are pumped out of the mitochondrial matrix. The resulting gradient of pH (the pH of the matrix -8 and the exterior pH -7) and the potential (~ -170 mV, negative interior) through the internal mitochondrial membrane constitute the electrochemical proton gradient. Taking into consideration that the effect of a difference of one pH unit corresponds to a potential of 61.5 mV, the proton electrochemical gradient exerts a proton motive force of approximately 230 mV, which is the driving force for the synthesis of mitochondrial ATP . When in this way the consumption of ATP, the cells respond by increasing the synthesis of ATP and consequently an influx of protons through ATP synthase, the enzyme responsible for the synthesis of ATP and therefore increases the metabolic rate. Chemical uncouplers are compounds which can transport protons through the membranes and when protons are transported through their inner mitochondrial membrane, ATP synthase is bypassed. On the side of the matrix (alkaline), the proton is released and the deprotonated uncoupling returns to the space between the membrane, where it captures another proton. The generation of the uncoupling cycle (or synthesis of ATP) and the resulting transport of protons generates an increased pumping out of protons through an increased oxidation of NADH and FADH2 by the respiratory chain. As a result, the concentration of NADH in the matrix will decrease.
Since the NADH feedback inhibits three stages in the TCA cycle (NADH is the main regulator of the TCA cycle), the flow through the TCA cycle will increase. Therefore, the metabolic rate will increase. Compounds such as chemical uncouplers, which act by increasing the metabolic rate in this way may be useful for treating obesity, but also for treating other diseases such as atherosclerosis, hypertension, diabetes, especially type 2 diabetes (NIDDM. English for non-insulin dependent diabetes mellitus), dyslipidemia, coronary heart disease, gallbladder disease, osteoarthritis and various types of cancer such as cancers of the endometrium, breast, prostate and colon as well as the risk of premature death and likewise other conditions such as diseases and disorders, conditions which improve by a reduced mitochondrial potential. In addition, chemical uncouplers can reduce reactive oxygen species (ROS) that are assumed (De Gray et al, Eur J. Biochem 269, 1995 ff (2002)) are involved in the aging process, in the damage of cardiac tissue as well as neuronal tissue. Therefore, it is also possible that the conditions affected by ROS are reversed or stopped by the intervention of chemical uncouplers. Examples of such conditions include diabetic microvascular diseases in the retina, glomerulrenal and peripheral nerve cells. The best-known chemical uncoupler "is 2,4-dinitrophenol (DNP), which has been shown to increase energy expenditure in humans as well as in animals.Side effects at high doses include increased perspiration , vasodilatation, skin flushes, cataracts, neuritis and death Two cases of deaths among the first and 100,000 people treated with DNP and the fact that the lowest dose can be fatal, given that only twice the average dose provides a desired increase 50% basal metabolic rate provides a very narrow safety interval combined with other factors, all this led to the withdrawal of DNP from the market.Since then nobody has tried to develop the market of uncoupling for the treatment of obesity.The DNP is the best known chemical uncoupling, but many other compounds that induce decoupling are known: DNP derivatives such as 4,6-dinitro-o-cresol (amar illo Victoria) and 2, -dinitro-l-naphthol (Martius yellow) also as structurally unrelated compounds such as 2,6-diterbutyl-4- (2 ', 2' -dicianovinyl) phenol) (SF6847) (also known as 2- (3, 5-diterbutyl-4-hydroxy-benzylidene) malonitrile), carbonylcyanide m-chlorophenylhydrazone (CCCP) and carbonylcyanide p-trifluoromethoxyphenylhydrazone (FCCP) (Miyoshi H et al. Quantitative releathionship between protenophoric and uncoupling activities of analogs of SF6847 (2, 6-di-t-butyl-4- (2 •, 2 '-dicyanovinyDphenol), Biochimica et Biophysica Acta 891, 293-299 (1987)) are uncoupling. Another class of chemical uncouplers are the salicylanilides of which S-13 is the most potent compound discovered so far (Terada H et al., Structural Requirements of Salicylanilides for Uncoupling Activity in Mitochondria, Quantitative Analysis of Structure, Uncoupling Relationships, Biochemistry and Biophysics, Acta 936). , 504-512 (1988)). WO00 / 06143 for Texas Pharmaceuticals Inc. is related to a method for inducing intracellular hyperthermia comprising a step of administering a mitochondrial uncoupling agent, such as 2,4-dinitrophenol. The document of E.U.A. 4,673,691 for Bachynsky is related to the use of 2,4-dinitrophenol to treat obesity. Various derivatives of salicylic anuide have been described in the literature. As an example, the document of E.U.A. 4,025,647 describes compounds of the formula: wherein R 1 can be hydrogen, X is the secondary or tertiary form of alkyl, R 2 alkanoyl, phenylsulfonynyl, phenylsulfonyl, etc., and Y is hydrogen or methyl. The compounds have anthelmintic activity, especially against hepatic atope. EP 322823 describes electrophotographic photoreceptors with the following formula halogen, etc. where A is a group of atoms necessary to condense the benzene ring with another ring. WO 01/44172 discloses compounds of the formula: wherein all X 'can be carbon, R1 can be hydroxyl, R2-R5 can be aryl, heteroaryl, alkylaryl, alkyl, ester, amide optionally substituted, etc. The compounds are inhibitors of serine proteases, urokinase, factor Xa, factor Vlla and have utility as anticancer and anticoagulant agents. R7 is amidine or guadinyl for all compounds specifically described in this application. WO 01/96944 describes compounds of the formula wherein R represents 0-4 substituents that are selected from alkyl, aryl, aralkyl, etc. The compounds are useful as components in colored photothermographic films. None of the specifically described compounds has an alkyl or branched phenyl as a substituent on the phenyl ring which is further to the left. WO 01/82924 describes compounds of the formula wherein R 1 -3 represents hydrogen, alkyl, halo, alkoxy, etc. The compounds are inhibitors of phosphate transport.

The compounds according to formula I can comprise chiral carbon atoms or carbon-carbon double bonds which can generate stereoisomeric forms, for example enantiomers, diastereoisomers and geometric isomers. The present invention relates to all of said isomers as either pure form or as mixtures thereof. The pure isomeric forms can be prepared from intermediates which in themselves are pure isomers, by purification of a mixture of isomers after synthesis or by combination of two methods. The purification of the isomeric forms is well known in the art, for example as described in Jaques in Enantiomers, Racemates and resolution, Wiley. 1981. The compounds of the present invention are useful in the treatment of diseases or conditions that benefit from an increase in mitochondrial respiration. The compounds of the present invention are considered to be particularly suitable for the treatment of obesity as such or to prevent weight gain for the treatment of diseases or disorders where obesity is involved in the etiology. In one embodiment, the invention in this manner provides a method for treating 1 metabolic syndrome, insulin resistance, dyslipidemia, hypertension, obesity, type 2 diabetes, type 1 diabetes, late diabetic complications that include cardiovascular diseases, cardiovascular disorders, lipid metabolism disorders, neurodegenerative and psychiatric disorders, lack of regulation of intraocular pressure that includes glaucoma, atherosclerosis, hypertension, coronary heart disease, gallbladder disease, osteoarthritis and cancer. More specifically, such conditions include the metabolic syndrome, type 2 diabetes (especially in obese patients), diabetes as a consequence of obesity, insulin resistance, hyperglycemia, prandial hyperglycemia, hyperinsulinemia, impaired glucose tolerance (IGT, by its acronym in English), glucose impaired fasting (IFG, for its acronym in English), increased production of hepatic glucose, type 1 diabetes, LADA, pediatric diabetes, dyslipidemia (especially in obese patients), diabetic dyslipidemia, hyperlipidemia , hypertriglyceridemia, hyperlipoproteinemia, micro- / macroalbuminuria, nephropathy, retinopathy,. neuropathy, diabetic ulcers, cardiovascular diseases, arteriosclerosis, coronary arthropathy, cardiac hypertrophy, myocardial ischemia, heart failure, congestive heart failure, stroke, myocardial infarction, arrhythmia, decreased blood flow, erectile dysfunction (male or female), myopathy, loss of muscle tissue, muscle wasting, muscle catabolism, osteoporosis, decreased linear growth, neurodegenerative and psychiatric disorders, Alzheimer's disease, neuronal death, impaired cognitive condition, depression, anxiety, eating disorders, appetite regulation, migraine, epilepsy, addiction to chemical substances, intraocular pressure disorders, bacterial infections, mycobacterial infections. In the present context it is intended that the cancer include forms such as hematological cancer such as leukemia, acute myeloid leukemia, chronic myeloid leukemia, chronic lymphatic leukemia, myelodysplasia, multiple myeloma, Hodking disease or forms of solid tumors such as fibrosarcoma, small or non-small cell lung carcinoma, gastric, intestinal or colorectal cancer, prostate, endometrial, ovarian or breast cancer, brain, head or neck cancer, cancer of the urinary tract such as kidney or bladder cancer , malignant melanoma, liver cancer, uterine and pancreatic cancer. In another embodiment, the invention relates to the use of a chemical decoupling according to the present invention to maintain a weight loss. The use of the compounds according to the present invention in the treatment of obesity in the same way can reduce or eliminate side effects such as skin irritation, glaucoma, etc., which are known from the treatment of obesity with DNP and Other chemical uncouplers with narrow safety intervals. Uncoupling can also reduce the release of insulin from the β-cells and therefore may be useful in providing rest to the β-cells. Rest induction of ß-cells may be useful in relation to ß-cell transplantation, and it has also been reported to induce ß-cells which may be useful in preventing diabetes. Anti-obesity drugs which regulate appetite and reduce food intake often have a lack of long-term efficacy in terms of body weight loss because the body, in response to treatment, slows down metabolism. In contrast, the compounds of the present invention increase metabolism and therefore are considered to be particularly suitable for maintaining weight loss. The compounds of the present invention are also considered to be particularly suitable for the treatment of diseases or disorders where reactive oxygen species are involved in the etiology, where a reduction in the amount of reactive oxygen species is beneficial. In a modality, the invention thus provides a method for treating, and in particular preventing, aging and damage to the heart, endothelial cells and neuronal tissue, diabetic microvascular diseases in the retina, renal glomeruli and peripheral nerve cells. The method comprises administering to a patient in need thereof a therapeutically effective amount of one or more compounds of the present invention to a patient in need thereof.

PHARMACOLOGICAL METHODS Assay (I): Use of glucose in a human epithelial cell line (FSK-4 cells) Description of the assay: The assay indirectly measures the activity of the respiratory chain in FSK-4 cells using D- (63- H (N) -glucose The 3H proton will first be released to the TCA cycle and transported to the respiratory chain where it will be incorporated into the water, then the water is separated from the D- (6-3H (N)) -glucose by evaporation Finally the radioactivity in the water is determined using a Topcounter equipment Method: FSK-4 cells obtained from ATCC (Maryland, USA) are grown in growth medium (McCoy's medium with the following addition: 100 units / ml of penicillin and streptomycin and fetal bovine serum ((FCS) 10%) at 37 ° C and 5% C02 All media are obtained from Gibco (Life Technologies, Maryland, USA) unless mentioned In another sense, on day zero, crops are harvested. cells using trypsin-EDTA and washed in assay medium (MEM medium with the following addition Ix of non-essential amino acids (M7145, 2 mM glutamine, 100 units / ml of penicillin and streptomycin, 0.0075% sodium bicarbonate, 1 mM sodium pyruvate and 2% horse serum) using centrifugation. Cells are plated in wells of single StripPlates vessels (Corning BV Life Sciences, The Netherlands) which are placed in 24 well plates (Corning BV Life Sciences, The Netherlands) with a concentration of 1.5 x 10 4 cells / 100 μl of assay medium / well. The cells are then incubated at 37 ° C and 5% C02 overnight. The next day the compounds to be tested are diluted to different concentrations in DMSO (Sigma, Missouri, E.U.A.) at 100 times the final concentration. They are then diluted to a final concentration in a test medium containing 10 μCi / ml of D- (6-3H (N)) -glucose (PerkinElmer Life Sciences Inc., Boston, E.U.A.). The medium is separated from the cells and 200 μl of the dilutions of the compound are added in duplicate. The cells are then incubated for a further 24 hours at 37 ° C and 5% C02. Finally, the cells are used when adding 50 μl of trichloroacetate (TCA, 10%). Subsequently, 300 μl of sterile water is added to the 24 wells surrounding the Strip-Plate wells. The plate is sealed with a Top-seal-tape top seal tape (Packard, PerkinElmer Life Sciences Inc., Boston, USA) and the plate is incubated in a 50 ° C heating cabinet at the equilibrium of the radioactive water formed in the Respiratory chain in the water in the 24-well plate by evaporation. The plates are incubated for 8 hours and then the cabinet heating is switched off. The upper seal is removed when the samples have reached room temperature. 1 ml of scintillation liquid (Packard Microscient, PerkinElmer Life Sciences Inc., Boston, U.S.A.) is added to all samples and the radioactivity is determined using a computer Topcounter (Packard, PerkinElmer Life Sciences Inc., Boston, U.S.A.). The non-specific activity is determined by evaporation of 200 μl of the dilution medium containing D- (6-3H (N)) -glucose in 300 μl of sterile water, and the total radioactivity is determined by making a count of 5 μl of assay medium with 10 μCi / ml of D- (6-3H (N)) -glucose. Calculations: The half-maximal concentration (EC50) and the maximum efficiency (Emax) are calculated using the Hill equation and the GraphPad Prism 3.0 program (GraphPad software, Inc.). In studies where the linear slope is determined, the following concentrations of the compounds are used: 5x, 3x, 2x, 1.5x, 1.25x, lx, 0.85x, 0.7x, 0.5x, 0.3x, 0.2x and Ox CE50. From the increase in the percentage in the utilization of glucose, the linear slope is calculated using the Michaelis-Menten equation.
Test (II). Effect of chemical uncouplers on mitochondrial respiration using isolated mitochondria. This test is used to investigate whether the increase in glucose utilization caused by the test compounds observed in the glucose utilization test is due to an increase in respiration of the mitochondria. This is done by determining the oxygen uptake in rat hepatic isolated mitochondria. A Clark oxygen electrode is used to determine oxygen consumption. The isolated mitochondria are added to assay medium (D-Mannitol, 220 mM, 5 mM magnesium chloride, 2 mM HEPES and 5 mM potassium phosphate, pH = 7.4) containing rotenone (a complex 1 inhibitor) and oligomycin ( an inhibitor of ATP-synthase) and the rate of oxygen consumption is measured when a stabilized nutrient (for example succinate) is added and the increase in the rate of oxygen consumption is measured. When the rate of oxygen consumption has stabilized again, the test compound is added and the oxygen consumption is measured. If the test compound stimulates the speed of oxygen consumption, it is considered to be a chemical uncoupling.
Test (III): Identification of chemical uncouplers that increase energy expenditure in vivo The effect of chemical uncouplers on energy expenditure (oxygen consumption) in vivo is determined by indirect calorimetry. Briefly, the animals are placed in air-tight chambers. Air is continuously administered and extracted from the chambers. The concentrations of oxygen gas (C02) and carbon dioxide in the air circulated in the chambers (inlet and outlet air) are recorded and the consumption of 02 and the production of CO2 are calculated. Based on the amount of 02 consumed and C0 produced, the energy expenditure is calculated. The compounds which, at a given dose, increase the total expenditure of body energy without obvious detrimental effects are considered to be chemical uncoupling which increases the expenditure of energy. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
