## Background
FIELD OF THE INVENTION
This invention relates to new compounds, in particular pyrrolidine derivatives, to processes for preparing such compounds, to their use as inhibitors of acetyl-CoA carboxylase(s), to methods for their therapeutic use, in particular in diseases and conditions mediated by the inhibition of acetyl-CoA carboxylase(s), and to pharmaceutical compositions comprising them.
BACKGROUND OF THE INVENTION
Obesity is a major public health issue not only for the EU, USA, Japan but also for the world in general. It is associated with a number of serious diseases including diabetes, dyslipidemia, hypertension, cardiovascular and cerebrovascular diseases. Although the underlying mechanisms are not yet fully understood, the impairement of insulin action in target tissues by accumulation of excess lipids is generally regarded as a key mechanism linking obesity to secondary pathologies (G. Wolf, Nutrition Reviews Vol. 66(10):597-600; D B Savage, K F Petersen, G I Shulman, Physiol Rev. 2007; 87:507-520). Therefore, understanding of cellular lipid metabolism in insulin target tissues is crucial in order to elucidate the development of diseases associated with obesity.
A central event in lipid metabolism is the generation of malonyl-CoA via carboxylation of acetyl-CoA by the two mammalian ACC isoforms ACC1 (ACC-alpha, also termed ACCA) and ACC2 (ACC-beta, also designated ACCB) (Saggerson D. Annu Rev Nutr. 2008; 28:253-72). The malonyl-CoA generated is used for de novo fatty acid synthesis and acts as inhibitor of CPT-1, thereby regulating mitochondrial fatty acid oxidation. Furthermore, malonyl-CoA is also described to act centrally to control food intake, and may play an important role in controlling insulin secretion from the pancreas (G D Lopaschuk, J R Ussher, J S Jaswal. Pharmacol Rev. 2010; 62(2):237-64; D Saggerson Annu Rev Nutr. 2008; 28:253-72), further coordinating the regulation of intermediary metabolism.
Therefore ACC1 and ACC2 have been shown to be major regulators of fatty acid metabolism and are presently considered as an attractive target to regulate the human diseases of obesity, diabetes and cardiovascular complications (S J Wakil and L A Abu-Elheiga, J. Lipid Res. 2009. 50: S138-S143; L. Tong, H J Harwood Jr. Journal of Cellular Biochemistry 99:1476-1488, 2006).
As a result of its unique position in intermediary metabolism, inhibition of ACC offers the ability to inhibit de novo fatty acid production in lipogenic tissues (liver and adipose) while at the same time stimulating fatty acid oxidation in oxidative tissues (liver, heart, and skeletal muscle) and therefore offers an attractive modality for favorably affecting, in a concerted manner, a multitude of cardiovascular risk factors associated with obesity, diabetes, insulin resistance, nonalcoholic steatohepatitis (NASH) and the metabolic syndrome (L. Tong, H J Harwood Jr. Journal of Cellular Biochemistry 99:1476-1488, 2006; Corbett J W, Harwood J H Jr., Recent Pat Cardiovasc Drug Discov. 2007 November; 2(3):162-80).
Furthermore recent data show that cellular toxicity mediated by lipids (lipotoxicity) is implicated in the susceptibitlity to diabetes associated nephropathy (for review see M Murea, B I Freedmann, J S Parks, P A Antinozzi, S C Elbein, L M Ma; Clin J Am Soc Nephrol. 2010; 5:2373-9). A large-scale genome-wide association study in japanese patients identified single nucleotide polymorphism in the ACC2 gene (ACACB) associated with diabetic nephropathy risk which was replicated in nine independent cohorts. In the kidney, dysregulation of fatty acid metabolism leading to increased fatty acid levels is believed to lead to glomerular and tubular dysfunction (M Murea, B I Freedmann, J S Parks, P A Antinozzi, S C Elbein, L M Ma; Clin J Am Soc Nephrol. 2010; 5:2373-9). Therefore inhibitors targeting ACC as key molecule involved in lipid oxidation have the potential to be beneficial for favorably affecting diabetic nephropathy.
Additionally, insulin resistance, deregulated lipid metabolism, lipotoxicity and increased intramuscular lipids have also been described to play a role in type 1 diabetes (I E Schauer, J K Snell-Bergeon, B C Bergman, D M Maahs, A Kretowski, R H Eckel, M Rewers Diabetes 2011; 60:306-14; P Ebeling, B Essén-Gustaysson, J A Tuominen and V A Koivisto Diabetologia 41: 111-115; K J Nadeau, J G Regensteiner, T A Bauer, M S Brown, J L Dorosz, A Hull, P Zeitler, B Draznin, J E B. Reusch J Clin Endocrinol Metab, 2010, 95:513-521). Therefore ACC inhibitors are also considered as interesting drugs for the treatment of type 1 diabetes.
In addition ACC inhibitors also have the potential to intervene in the progression of diseases that result from the rapid growth of malignant cells or invading organisms that are dependent on endogenous lipid synthesis to sustain their rapid proliferation. De novo lipogenesis is known to be required for growth of many tumor cells and ACC up-regulation has been recognized in multiple human cancers, promoting lipogenesis to meet the need of cancer cells for rapid growth and proliferation (C Wang, S Rajput, K Watabe, D F Liao, D Cao Front Biosci 2010; 2:515-26). This is further demonstrated in studies using ACC inhibitors which induced growth arrest and selective cytotoxicity in cancer cells and by RNA interference-mediated knock-down of ACC which inhibited growth and induced apoptosis in different types of cancer cells. Furthermore, ACC1 associates with and is regulated by the breast cancer susceptibility gene 1 (BRCA1). Commonly occurring BRCA1 mutations lead to ACC1 activation and breast cancer susceptibility (C Wang, S Rajput, K Watabe, D F Liao, D Cao Front Biosci 2010; 2:515-26).
Furthermore in central nervous system disorders including but not limited to Alzheimer's disease, Parkinson disease and epilepsy, impairements in neuronal energy metabolism have been described (Ogawa M, Fukuyama H, Ouchi Y, Yamauchi H, Kimura J, J Neurol Sci. 1996; 139(1):78-82). Interventions targeting this metabolic defect may prove beneficial to the patients. One promising intervention is therefore to provide the glucose-compromised neuronscerebral brain neurons with ketone bodies as an alternative substrate (S T Henderson Neurotherapeutics, 2008, 5:470-480; L C Costantini, L J Barr, J L Vogel, S T Henderson BMC Neurosci. 2008, 9 Suppl 2:S16; K W Baranano, A L Hartman. Curr Treat Options Neurol. 2008; 10:410-9). ACC inhibition leading to increased fatty acid oxidation may thereby result in increases in the blood levels of ketone bodies thereby providing an alternative energy substrate for the brain.
Preclinical and clinical evidence indicates that ketone bodies can provide neuroprotective effects in models of Parkinson's disease, A D, hypoxia, ischemia, amyotrophic lateral sclerosis and glioma (L C Costantini, L J Barr, J L Vogel, S T Henderson BMC Neurosci. 2008, 9 Suppl 2:S16) and improved cognitive scores in Alzheimers Diseases patients (M A Reger, S T Henderson, C Hale, B Cholerton, L D Baker, G S Watson, K Hydea, D Chapmana, S Craft Neurobiology of Aging 25 (2004) 311-314). The end result of increased ketone levels is an improvement in mitochondrial efficiency and reduction in the generation of reactive oxygen species (for reviews see L C Costantini, L J Barr, J L Vogel, S T Henderson BMC Neurosci. 2008, 9 Suppl 2:S16; K W Barahano, A L Hartman. Curr Treat Options Neurol. 2008; 10:410-9).
Furthermore, the potential of ACC inhibitors as antifungal agents and as antibacterial agents is well documented (L. Tong, H J Harwood Jr. Journal of Cellular Biochemistry 99:1476-1488, 2006). In addition, ACC inhibitors can be used to combat viral infections. It was discovered recently that viruses rely on the metabolic network of their cellular hosts to provide energy and building blocks for viral replication (Munger J, B D Bennett, A Parikh, X J Feng, J McArdle, H A Rabitz, T Shenk, J D Rabinowitz. Nat. Biotechnol. 2008; 26:1179-86). A flux measurement approach to quantify changes in metabolic activity induced by human cytomegalovirus (HCMV) elucidated that infection with HCMV markedly changed fluxes through much of the central carbon metabolism, including glycolysis, tricarboxylic acid cycle and fatty acid biosynthesis. Pharmacological inhibition of fatty acid biosynthesis suppressed the replication of two divergent enveloped viruses (HCMV and influenza A) indicating that fatty acid synthesis is essential for the replication. These examples show that acetyl-CoA fluxes and de novo fatty acid biosynthesis are critical to viral survival and propagation as the newly synthesized fatty acids and phospholipids are important for formation of viral envelopes. Changing the metabolic flux influences the absolute quantity of phospholipid available, the chemical composition and physical properties of the envelope negatively affect viral growth and replication. Hence, ACC inhibitors acting on key enzymes in the fatty acid metabolism, have the potential to be antiviral drugs.

The compounds according to the invention may be obtained using methods of synthesis which are known to the one skilled in the art and described in the literature of organic synthesis. Preferably, the compounds are obtained analogously to the methods of preparation explained more fully hereinafter, in particular as described in the experimental section.
Terms and Definitions
Terms not specifically defined herein should be given the meanings that would be given to them by one of skill in the art in light of the disclosure and the context. As used in the specification, however, unless specified to the contrary, the following terms have the meaning indicated and the following conventions are adhered to.
The terms “compound(s) according to this invention”, “compound(s) of formula (I)”, “compound(s) of the invention” and the like denote the compounds of the formula (I) according to the present invention including their tautomers, stereoisomers and mixtures thereof and the salts thereof, in particular the pharmaceutically acceptable salts thereof, and the solvates and hydrates of such compounds, including the solvates and hydrates of such tautomers, stereoisomers and salts thereof.
The terms “treatment” and “treating” embraces both preventative, i.e. prophylactic, or therapeutic, i.e. curative and/or palliative, treatment. Thus the terms “treatment” and “treating” comprise therapeutic treatment of patients having already developed said condition, in particular in manifest form. Therapeutic treatment may be symptomatic treatment in order to relieve the symptoms of the specific indication or causal treatment in order to reverse or partially reverse the conditions of the indication or to stop or slow down progression of the disease. Thus the compositions and methods of the present invention may be used for instance as therapeutic treatment over a period of time as well as for chronic therapy. In addition the terms “treatment” and “treating” comprise prophylactic treatment, i.e. a treatment of patients at risk to develop a condition mentioned hereinbefore, thus reducing said risk.
When this invention refers to patients requiring treatment, it relates primarily to treatment in mammals, in particular humans.
The term “therapeutically effective amount” means an amount of a compound of the present invention that (i) treats or prevents the particular disease or condition, (ii) attenuates, ameliorates, or eliminates one or more symptoms of the particular disease or condition, or (iii) prevents or delays the onset of one or more symptoms of the particular disease or condition described herein.
The terms “modulated” or “modulating”, or “modulate(s)”, as used herein, unless otherwise indicated, refers to the inhibition of acetyl-CoA carboxylase(s) (ACC) with one or more compounds of the present invention.
The terms “mediated” or “mediating” or “mediate”, as used herein, unless otherwise indicated, refers to the (i) treatment, including prevention the particular disease or condition, (ii) attenuation, amelioration, or elimination of one or more symptoms of the particular disease or condition, or (iii) prevention or delay of the onset of one or more symptoms of the particular disease or condition described herein.
The term “substituted” as used herein, means that any one or more hydrogens on the designated atom, radical or moiety is replaced with a selection from the indicated group, provided that the atom's normal valence is not exceeded, and that the substitution results in an acceptably stable compound.
In the groups, radicals, or moieties defined below, the number of carbon atoms is often specified preceding the group, for example, C1-6-alkyl means an alkyl group or radical having 1 to 6 carbon atoms. In general, for groups comprising two or more subgroups, the last named subgroup is the radical attachment point, for example, the substituent “aryl-C1-3-alkyl-” means an aryl group which is bound to a C1-3-alkyl-group, the latter of which is bound to the core or to the group to which the substituent is attached.
In case a compound of the present invention is depicted in form of a chemical name and as a formula in case of any discrepancy the formula shall prevail.
An asterisk is may be used in sub-formulas to indicate the bond which is connected to the core molecule as defined.
The numeration of the atoms of a substituent starts with the atom which is closest to the core or to the group to which the substituent is attached.
For example, the term “3-carboxypropyl-group” represents the following substituent:




wherein the carboxy group is attached to the third carbon atom of the propyl group. The terms “1-methylpropyl-”, “2,2-dimethylpropyl-” or “cyclopropylmethyl-” group represent the following groups:





The asterisk may be used in sub-formulas to indicate the bond which is connected to the core molecule as defined.
In a definition of a group the term “wherein each X, Y and Z group is optionally substituted with” and the like denotes that each group X, each group Y and each group Z either each as a separate group or each as part of a composed group may be substituted as defined. For example a definition “Rex denotes H, C1-3-alkyl, C3-6-cycloalkyl, C3-6-cycloalkyl-C1-3-alkyl or C1-3-alkyl-O—, wherein each alkyl group is optionally substituted with one or more Lex.” or the like means that in each of the beforementioned groups which comprise the term alkyl, i.e. in each of the groups C1-3-alkyl, C3-6-cycloalkyl-C1-3-alkyl and C1-3-alkyl-O—, the alkyl moiety may be substituted with Lex as defined.
In the following the term bicyclic includes spirocyclic.
Unless specifically indicated, throughout the specification and the appended claims, a given chemical formula or name shall encompass tautomers and all stereo, optical and geometrical isomers (e.g. enantiomers, diastereomers, E/Z isomers etc. . . . ) and racemates thereof as well as mixtures in different proportions of the separate enantiomers, mixtures of diastereomers, or mixtures of any of the foregoing forms where such isomers and enantiomers exist, as well as salts, including pharmaceutically acceptable salts thereof and solvates thereof such as for instance hydrates including solvates of the free compounds or solvates of a salt of the compound.
The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, and commensurate with a reasonable benefit/risk ratio.
As used herein, “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like.
The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a sufficient amount of the appropriate base or acid in water or in an organic diluent like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile, or a mixture thereof.
Salts of other acids than those mentioned above which for example are useful for purifying or isolating the compounds of the present invention also comprise a part of the invention.
The term halogen generally denotes fluorine, chlorine, bromine and iodine.

Pharmacological Activity
The activity of the compounds of the invention may be demonstrated using the following ACC2 assay:
Spectrophotometric 384 Well Assay
Malonyl CoA formation by acetyl CoA carboxylases is stoichometrically linked to the consumption of ATP. ACC2 activity is measured in a NADH-linked kinetic method measuring ADP generated during the ACC reaction using a coupled lactate dehydrogenase/pyruvate kinase reaction.
For biological testing, a human ACC2 construct which lacks the 128 amino acids at the N-terminus for increased solubility (nt 385-6966 in Genbank entry AJ575592) is cloned. The protein is then expressed in insect cells using a baculoviral expression system. Protein purification is performed by anion exchange.
All compounds are dissolved in dimethyl sulfoxide (DMSO) to a concentration of 10 mM.
Assay reactions are then carried out in 384-well plates, with hACC2 in an appropriate dilution and at final assay concentrations (f.c.) of 100 mM Tris (pH 7.5), 10 mM trisodium citrate, 25 mM KHCO3, 10 mM MgCl2, 0.5 mg/ml BSA, 3.75 mM reduced L-glutathione, 15 U/ml lactate dehydrogenase, 0.5 mM phosphoenolpyruvate, 15 U/ml pyruvate kinase, compounds at different concentrations at final DMSO concentrations of 1%.
The enzymatic reaction is then started by addition of a mixture of NADH, acetyl
Coenzyme A (both 2000 f.c.) and ATP (500 uM f.c.). The decrease of the optical density (slope S) is then determined at 25° C. at a wavelength of 340 nm over 15 minutes in a spectrophotometric reader.
Each assay microtiter plate contains wells with vehicle instead of compound as controls for the non-inhibited enzyme (100% CTL; ‘HIGH’) and wells without acetyl-CoA as controls for non-specific NADH degradation (0% CTL; ‘LOW’).
The slope S is used for calculation of % CTL=(S(compound)−S(‘LOW’))/(S(‘HIGH’)−S(‘LOW’))*100. Compounds will give values between 100% CTL (no inhibition) and 0% CTL (complete inhibition).
For IC50 value determination, the sample slope in the presence of the test compound after subtraction of the low controls (S(compound)−S(‘LOW’)) are used.
An IC50 value is derived from the compound slopes at different dosages after subtraction of the low controls (S(compound)−S(‘LOW’)) by non-linear regression curve fitting (equation y=(A+((B−A)/(1+((C/x)^D))))).
The compounds of general formula (I) according to the invention for example have IC50 values below 5000 nM, particularly below 1000 nM, preferably below 300 nM, most preferably below 100 nM.
In the following table the activity expressed as IC50 (μM) of compounds according to the invention is presented wherein the IC50 values are determined in the ACC2 assay as described hereinbefore. The term “Example” refers to the example numbers according to the following experimental section.

The synthetic routes presented may rely on the use of protecting groups. For example, reactive groups present, such as hydroxy, carbonyl, carboxy, amino, alkylamino or imino, may be protected during the reaction by conventional protecting groups which are cleaved again after the reaction. Suitable protecting groups for the respective functionalities and their removal are well known to the one skilled in the art and are described in the literature of organic synthesis.
The compounds of general formula I may be resolved into their enantiomers and/or diastereomers as mentioned before. Thus, for example, cis/trans mixtures may be resolved into their cis and trans isomers and racemic compounds may be separated into their enantiomers.
The cis/trans mixtures may be resolved, for example, by chromatography into the cis and trans isomers thereof. The compounds of general formula I which occur as racemates may be separated by methods known per se into their optical antipodes and diastereomeric mixtures of compounds of general formula I may be resolved into their diastereomers by taking advantage of their different physico-chemical properties using methods known per se, e.g. chromatography and/or fractional crystallization; if the compounds obtained thereafter are racemates, they may be resolved into the enantiomers as mentioned above.
The racemates are preferably resolved by column chromatography on chiral phases or by crystallization from an optically active solvent or by reacting with an optically active substance which forms salts or derivatives such as esters or amides with the racemic compound. Salts may be formed with enantiomerically pure acids for basic compounds and with enantiomerically pure bases for acidic compounds. Diastereomeric derivatives are formed with enantiomerically pure auxiliary compounds, e.g. acids, their activated derivatives, or alcohols. Separation of the diastereomeric mixture of salts or derivatives thus obtained may be achieved by taking advantage of their different physico-chemical properties, e.g. differences in solubility; the free antipodes may be released from the pure diastereomeric salts or derivatives by the action of suitable agents. Optically active acids commonly used for such a purpose as well as optically active alcohols applicable as auxiliary residues are known to those skilled in the art.
As mentioned above, the compounds of formula I may be converted into salts, particularly for pharmaceutical use into the pharmaceutically acceptable salts. As used herein, “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof.
