## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims priority from co-pending U.S. provisional patent application No. 61/511/769, filed Jul. 26, 2011, the entire disclosure of which is incorporated herein by reference. Priority is also claimed based on European patent application no. EP 11 001 113.2, filed Jul. 26, 2011, the entire disclosure of which is likewise incorporated herein by reference.


BACKGROUND OF THE INVENTION
The invention relates to substituted bicyclic aromatic carboxamide and urea derivatives as vanilloid receptor ligands, to pharmaceutical compositions containing these compounds and also to these compounds for use in the treatment and/or inhibition of pain and further diseases and/or disorders.
The treatment of pain, in particular of neuropathic pain, is very important in medicine. There is a worldwide demand for effective pain therapies. The urgent need for action for a patient-focused and target-oriented treatment of chronic and non-chronic states of pain, this being understood to mean the successful and satisfactory treatment of pain for the patient, is also documented in the large number of scientific studies which have recently appeared in the field of applied analgesics or basic research on nociception.
The subtype 1 vanilloid receptor (VR1/TRPV1), which is often also referred to as the capsaicin receptor, is a suitable starting point for the treatment of pain, in particular of pain selected from the group consisting of acute pain, chronic pain, neuropathic pain and visceral pain. This receptor is stimulated inter alia by vanilloids such as capsaicin, heat and protons and plays a central role in the formation of pain. In addition, it is important for a large number of further physiological and pathophysiological processes and is a suitable target for the therapy of a large number of further disorders such as, for example, migraine, depression, neurodegenerative diseases, cognitive disorders, states of anxiety, epilepsy, coughs, diarrhoea, pruritus, inflammations, disorders of the cardiovascular system, eating disorders, medication dependency, misuse of medication and urinary incontinence.
There is a demand for further compounds having comparable or better properties, not only with regard to affinity to vanilloid receptors 1 (VR1/TRPV1 receptors) per se (potency, efficacy).
Thus, it may be advantageous to improve the metabolic stability, the solubility in aqueous media or the permeability of the compounds. These factors can have a beneficial effect on oral bioavailability or can alter the PK/PD (pharmacokinetic/pharmacodynamic) profile; this can lead to a more beneficial period of effectiveness, for example.
SUMMARY OF THE INVENTION
It was therefore an object of the invention to provide novel compounds, preferably having advantages over the prior-art compounds.
Another object of the invention was to provide new compounds which are suitable in particular as pharmacological active ingredients in pharmaceutical compositions.
It was also a particular object of the invention to provide new compounds useful for the treatment and/or inhibition of disorders or diseases which are at least partially mediated by vanilloid receptors 1 (VR1/TRPV1 receptors).
These and other objects have been achieved in accordance with the present invention by the compounds, compositions and methods as described and claimed hereinafter.
It has surprisingly been found that the substituted compounds of general formula (I), as given below, display outstanding affinity to the subtype 1 vanilloid receptor (VR1/TRPV1 receptor) and are therefore particularly suitable for the inhibition and/or treatment of disorders or diseases which are at least partially mediated by vanilloid receptors 1 (VR1/TRPV1).
The present invention therefore relates to a substituted compound of general formula (I),

Particularly preferred substituents of “aryl” and “heteroaryl” are selected from the group consisting of F; Cl; Br; I; NO2; CF3; CN; C1-8 aliphatic residue; aryl; heteroaryl; C3-6 cycloaliphatic residue; 3 to 6 membered heterocycloaliphatic residue; aryl, heteroaryl, C3-6 cycloaliphatic residue or 3 to 6 membered heterocycloaliphatic bridged via a C1-4 aliphatic group; CHO; C(═O)—C1-8 aliphatic residue; C(═O)aryl; C(═O)heteroaryl; CO2H; C(═O)O—C1-8 aliphatic residue; C(═O)O-aryl; C(═O)O-heteroaryl; CONH2; C(═O)NH—C1-8 aliphatic residue; C(═O)N(C1-8 aliphatic residue)2; C(═O)NH-aryl; C(═O)N(aryl)2; C(═O)NH-heteroaryl; C(═O)N(heteroaryl)2; C(═O)N(C1-8 aliphatic residue)(aryl); C(═O)N(C1-8 aliphatic residue)(heteroaryl); C(═O)N(heteroaryl)(aryl); OH; O—C1-8 aliphatic residue; OCF3; O—(C1-8 aliphatic group)-OH; O—(C1-8 aliphatic group)-O—C1-8 aliphatic residue; O-benzyl; O-aryl; O-heteroaryl; O—C(═O)—C1-3 aliphatic residue; O—C(═O)aryl; O—C(═O)heteroaryl; NH2, NH—C1-8 aliphatic residue; N(C1-8 aliphatic residue)2; NH—C(═O)—C1-8 aliphatic residue; NH—C(═O)-aryl; NH—C(═O)-heteroaryl; SH; S—C1-8 aliphatic residue; SCF3; S-benzyl; S-aryl; S-heteroaryl; S(═O)2—C1-8 aliphatic residue; S(═O)2 aryl; S(═O)2 heteroaryl; S(═O)2OH; S(═O)2O—C1-8 aliphatic residue; S(═O)2O-aryl; S(═O)2O-heteroaryl; S(═O)2—NH—C1-8 aliphatic residue; S(═O)2—NH-aryl; and S(═O)2—NH-heteroaryl.
The compounds according to the invention are defined by substituents, for example by R1, R2 and R3 (1st generation substituents) which are for their part if appropriate themselves substituted (2nd generation substituents). Depending on the definition, these substituents of the substituents can for their part be resubstituted (3rd generation substituents). If, for example, R1=a C1-4 aliphatic residue (1st generation substituent), then the C1-4 aliphatic residue can for its part be substituted, for example with a NH—C1-4 aliphatic residue (2nd generation substituent). This produces the functional group R1=(C1-4 aliphatic residue-NH—C1-4 aliphatic residue). The NH—C1-4 aliphatic residue can then for its part be resubstituted, for example with Cl (3rd generation substituent). Overall, this produces the functional group R1=C1-4 aliphatic residue-NH—C1-4 aliphatic residue, wherein the C1-4 aliphatic residue of the NH—C1-4 aliphatic residue is substituted by Cl.
However, in a preferred embodiment, the 3rd generation substituents may not be resubstituted, i.e. there are then no 4th generation substituents.
In another preferred embodiment, the 2nd generation substituents may not be resubstituted, i.e. there are then not even any 3rd generation substituents. In other words, in this embodiment, in the case of general formula (I), for example, the functional groups for R1 to R9 can each if appropriate be substituted; however, the respective substituents may then for their part not be resubstituted.
In some cases, the compounds according to the invention are defined by substituents which are or carry an aryl or heteroaryl residue, respectively unsubstituted or mono- or polysubstituted, or which form together with the carbon atom(s) or heteroatom(s) connecting them, as the ring member or as the ring members, a ring, for example an aryl or heteroaryl, in each case unsubstituted or mono- or polysubstituted. Both these aryl or heteroaryl residues and the (hetero)aromatic ring systems formed in this way can if appropriate be condensed with a cycloaliphatic, preferably a C3-6 cycloaliphatic residue, or heterocycloaliphatic residue, preferably a 3 to 6 membered heterocycloaliphatic residue, or with aryl or heteroaryl, e.g. with a C3-6 cycloaliphatic residue such as cyclopentyl, or a 3 to 6 membered heterocycloaliphatic residue such as morpholinyl, or an aryl such as phenyl, or a heteroaryl such as pyridyl, wherein the cycloaliphatic or heterocycloaliphatic residues, aryl or heteroaryl residues condensed in this way can for their part be respectively unsubstituted or mono- or polysubstituted.
In some cases, the compounds according to the invention are defined by substituents which are or carry a cycloaliphatic residue or a heterocycloaliphatic residue, respectively, in each case unsubstituted or mono- or polysubstituted, or which form together with the carbon atom(s) or heteroatom(s) connecting them, as the ring member or as the ring members, a ring, for example a cycloaliphatic or a heterocycloaliphatic ring system. Both these cycloaliphatic or heterocycloaliphatic ring systems and the (hetero)cycloaliphatic ring systems formed in this manner can if appropriate be condensed with aryl or heteroaryl, preferably selected from the group consisting of phenyl, pyridyl and thienyl, or with a cycloaliphatic residue, preferably a C3-6 cycloaliphatic residue, or a heterocycloaliphatic residue, preferably a 3 to 6 membered heterocycloaliphatic residue, e.g. with an aryl such as phenyl, or a heteroaryl such as pyridyl, or a cycloaliphatic residue such as cyclohexyl, or a heterocycloaliphatic residue such as morpholinyl, wherein the aryl or heteroaryl residues or cycloaliphatic or heterocycloaliphatic residues condensed in this way can for their part be respectively unsubstituted or mono- or polysubstituted.
Within the scope of the present invention, the symbol




used in the formulas denotes a link of a corresponding residue to the respective superordinate general structure.

If a residue occurs multiple times within a molecule, then this residue can have respectively different meanings for various substituents: if, for example, both R1 and R2 denote a 3 to 6 membered heterocycloaliphatic residue, then the 3 to 6 membered heterocycloaliphatic residue can e.g. represent morpholinyl for R1 and can represent piperazinyl for R2.
If a residue occurs multiply within a molecule, such as for example the residue R0, then this residue can have respectively different meanings for various substituents.
The term “(R0 or H)” within a residue means that R0 and H can occur within this residue in any possible combination. Thus, for example, the residue “N(R0 or H)2” can represent “NH2”, “NHR0” and “N(R0)2”. If, as in the case of “N(R0)2”, R0 occurs multiply within a residue, then R0 can respectively have the same or different meanings: in the present example of “N(R0)2”, R0 can for example represent aryl twice, thus producing the functional group “N(aryl)2”, or R0 can represent once aryl and once a C1-10 aliphatic residue, thus producing the functional group “N(aryl)(C1-10 aliphatic residue)”.
The terms “salt formed with a physiologically compatible acid” or “salt of physiologically acceptable acids” refers in the sense of this invention to salts of the respective active ingredient with inorganic or organic acids which are physiologically compatible—in particular when used in human beings and/or other mammals. Examples of physiologically acceptable acids are: hydrochloric acid, hydrobromic acid, sulfuric acid, methanesulfonic acid, p-toluenesulfonic acid, carbonic acid, formic acid, acetic acid, oxalic acid, succinic acid, tartaric acid, mandelic acid, fumaric acid, maleic acid, lactic acid, citric acid, glutamic acid, saccharic acid, monomethylsebacic acid, 5-oxoproline, hexane-1-sulfonic acid, nicotinic acid, 2, 3 or 4-aminobenzoic acid, 2,4,6-trimethylbenzoic acid, α-lipoic acid, acetyl glycine, hippuric acid, phosphoric acid, aspartic acid. Citric acid and hydrochloric acid are particularly preferred.
The terms “salt formed with a physiologically compatible base” or “salt of physiologically acceptable bases” refers in the sense of this invention to salts of the respective compound according to the invention—as an anion, e.g. upon deprotonation of a suitable functional group—with at least one cation or base—preferably with at least one inorganic cation—which are physiologically acceptable—in particular when used in human beings and/or other mammals. Particularly preferred are the salts of the alkali and alkaline earth metals, in particular (mono-) or (di)sodium, (mono-) or (di)potassium, magnesium or calcium salts, but also ammonium salts [NHxR4-x]+, in which x=0, 1, 2, 3 or 4 and R represents a branched or unbranched C1-4 aliphatic residue.

If appropriate, the person skilled in the art can determine the optimum procedure under the respective conditions by carrying out simple preliminary tests. The intermediate and end products obtained using the reactions described hereinbefore can each be purified and/or isolated, if desired and/or required, using conventional methods known to the person skilled in the art. Suitable purifying processes are for example extraction processes and chromatographic processes such as column chromatography or preparative chromatography. All of the process steps of the reaction sequences which can be applied for synthesizing the compounds according to the present invention as well as the respective purification and/or isolation of intermediate or end products, can be carried out partly or completely under an inert gas atmosphere, preferably under a nitrogen atmosphere.
The substituted compounds according to the invention can be isolated both in the form of their free bases, their free acids and also in the form of corresponding salts, in particular physiologically compatible salts, i.e. physiologically acceptable salts.
The free bases of the respective substituted compounds according to the invention can be converted into the corresponding salts, preferably physiologically compatible salts, for example by reaction with an inorganic or organic acid, preferably with hydrochloric acid, hydrobromic acid, sulfuric acid, methanesulfonic acid, p-toluenesulfonic acid, carbonic acid, formic acid, acetic acid, oxalic acid, succinic acid, tartaric acid, mandelic acid, fumaric acid, maleic acid, lactic acid, citric acid, glutamic acid, saccharic acid, monomethylsebacic acid, 5-oxoproline, hexane-1-sulfonic acid, nicotinic acid, 2, 3 or 4-aminobenzoic acid, 2,4,6-trimethylbenzoic acid, α-lipoic acid, acetyl glycine, hippuric acid, phosphoric acid and/or aspartic acid. The free bases of the respective substituted compounds of the aforementioned general formula (I) and of corresponding stereoisomers can likewise be converted into the corresponding physiologically compatible salts using the free acid or a salt of a sugar additive, such as for example saccharin, cyclamate or acesulfame.
Accordingly, the free acids of the substituted compounds according to the invention can be converted into the corresponding physiologically compatible salts by reaction with a suitable base. Examples include the alkali metal salts, alkaline earth metals salts or ammonium salts [NHxR4-x]+, in which x=0, 1, 2, 3 or 4 and R represents a branched or unbranched C1-4 aliphatic residue.

Pharmacological Methods

I. Functional Testing Carried Out on the Vanilloid Receptor 1 (VR1/TRPV1 Receptor)

The agonistic or antagonistic effect of the substances to be tested on the rat-species vanilloid receptor 1 (VR1/TRPV1) can be determined using the following assay. In this assay, the influx of Ca2+ through the receptor channel is quantified with the aid of a Ca2+-sensitive dye (type Fluo-4, Molecular Probes Europe BV, Leiden, the Netherlands) in a fluorescent imaging plate reader (FLIPR, Molecular Devices, Sunnyvale, USA).
Method:
Complete medium: 50 mL HAMS F12 nutrient mixture (Gibco Invitrogen GmbH, Karlsruhe, Germany) with 10% by volume of FCS (foetal calf serum, Gibco Invitrogen GmbH, Karlsruhe, Germany, heat-inactivated); 2 mM L-glutamine (Sigma, Munich, Germany); 1% by weight of AA solution (antibiotic/antimyotic solution, PAA, Pasching, Austria) and 25 ng/mL NGF medium (2.5 S, Gibco Invitrogen GmbH, Karlsruhe, Germany)
Cell culture plate: Poly-D-lysine-coated, black 96-well plates having a clear base (96-well black/clear plate, BD Biosciences, Heidelberg, Germany) are additionally coated with laminin (Gibco Invitrogen GmbH, Karlsruhe, Germany), the laminin being diluted with PBS (Ca—Mg-free PBS, Gibco Invitrogen GmbH, Karlsruhe, Germany) to a concentration of 100 μg/mL. Aliquots having a laminin concentration of 100 μg/mL are removed and stored at −20° C. The aliquots are diluted with PBS in a ratio of 1:10 to 10 μg/mL of laminin and respectively 50 μL of the solution are pipetted into a recess in the cell culture plate. The cell culture plates are incubated for at least two hours at 37° C., the excess solution is removed by suction and the recesses are each washed twice with PBS. The coated cell culture plates are stored with excess PBS which is not removed until just before the feeding of the cells.
Preparation of the Cells:
The vertebral column is removed from decapitated rats and placed immediately into cold HBSS buffer (Hank's buffered saline solution, Gibco Invitrogen GmbH, Karlsruhe, Germany), i.e. buffer located in an ice bath, mixed with 1% by volume (percent by volume) of an AA solution (antibiotic/antimyotic solution, PAA, Pasching, Austria). The vertebral column is cut longitudinally and removed together with fasciae from the vertebral canal. Subsequently, the dorsal root ganglia (DRG) are removed and again stored in cold HBSS buffer mixed with 1% by volume of an AA solution. The DRG, from which all blood remnants and spinal nerves have been removed, are transferred in each case to 500 μL of cold type 2 collagenase (PAA, Pasching, Austria) and incubated for 35 minutes at 37° C. After the addition of 2.5% by volume of trypsin (PAA, Pasching, Austria), incubation is continued for 10 minutes at 37° C. After complete incubation, the enzyme solution is carefully pipetted off and 500 μL of complete medium are added to each of the remaining DRG. The DRG are respectively suspended several times, drawn through cannulae No. 1, No. 12 and No. 16 using a syringe and transferred to a 50 mL Falcon tube which is filled up to 15 mL with complete medium. The contents of each Falcon tube are respectively filtered through a 70 μm Falcon filter element and centrifuged for 10 minutes at 1,200 rpm and room temperature. The resulting pellet is respectively taken up in 250 μL of complete medium and the cell count is determined.
The number of cells in the suspension is set to 3×105 per mL and 150 μL of this suspension are in each case introduced into a recess in the cell culture plates coated as described hereinbefore. In the incubator the plates are left for two to three days at 37° C., 5% by volume of CO2 and 95% relative humidity. Subsequently, the cells are loaded with 2 μM of Fluo-4 and 0.01% by volume of Pluronic F127 (Molecular Probes Europe BV, Leiden, the Netherlands) in HBSS buffer (Hank's buffered saline solution, Gibco Invitrogen GmbH, Karlsruhe, Germany) for 30 min at 37° C., washed 3 times with HBSS buffer and after further incubation for 15 minutes at room temperature used for Ca2+ measurement in a FLIPR assay. The Ca2+-dependent fluorescence is in this case measured before and after the addition of substances (λex=488 nm, λem=540 nm). Quantification is carried out by measuring the highest fluorescence intensity (FC, fluorescence counts) over time.
FLIPR Assay:
The FLIPR protocol consists of 2 substance additions. First the compounds to be tested (10 μM) are pipetted onto the cells and the Ca2+ influx is compared with the control (capsaicin 10 μM). This provides the result in % activation based on the Ca2+ signal after the addition of 10 μM of capsaicin (CP). After 5 minutes' incubation, 100 nM of capsaicin are applied and the Ca2+ influx is also determined.
Desensitising agonists and antagonists lead to suppression of the Ca2+ influx. The % inhibition is calculated compared to the maximum achievable inhibition with 10 μM of capsazepine. Triple analyses (n=3) are carried out and repeated in at least 3 independent experiments (N=4). Starting from the percentage displacement caused by different concentrations of the compounds to be tested of general formula I, IC50 inhibitory concentrations which cause a 50-percent displacement of capsaicin were calculated. Ki values for the test substances were obtained by conversion by means of the Cheng-Prusoff equation (Cheng, Prusoff; Biochem. Pharmacol. 22, 3099-3108, 1973).
Pharmacological Data
The affinity of the compounds of to the invention for the vanilloid receptor 1 (VR1/TRPV1 receptor) was determined as described hereinbefore (pharmacological method I). The compounds of the invention display outstanding affinity to the VR1/TRPV1 receptor (Table 2). In Table 2 the abbreviations below have the following meanings:

    
    
        Cap=capsaicin
        AG=agonist
        NE=no effect
    
    


The value after the “@” symbol indicates the concentration at which the inhibition (as a percentage) was respectively determined.
