The invention relates to substituted 4-aminobenzamides, to pharmaceutical compositions containing these compounds and also to these compounds for use in the treatment and/or prophylaxis of pain and further diseases and/or disorders.
The treatment of pain, in particular of neuropathic pain, is of great importance in medicine. There is a worldwide need for effective pain therapies. The urgent need for action for a target-orientated treatment of chronic and non-chronic states of pain appropriate for the patient, by which is to be understood the successful and satisfactory treatment of pain for the patient, is also documented in the large number of scientific works which have recently been published in the field of applied analgesics and of fundamental research into nociception.
A pathophysiological feature of chronic pain is the overexcitability of neurons. Neuronal excitability is influenced decisively by the activity of K+ channels, since these determine decisively the resting membrane potential of the cell and therefore the excitability threshold. Heteromeric K+ channels of the molecular subtype KCNQ2/3 (Kv7.2/7.3) are expressed in neurons of various regions of the central (hippocampus, amygdala) and peripheral (dorsal root ganglia) nervous system and regulate the excitability thereof. Activation of KCNQ2/3 K+ channels leads to a hyperpolarization of the cell membrane and, accompanying this, to a decrease in the electrical excitability of these neurons. KCNQ2/3-expressing neurons of the dorsal root ganglia are involved in the transmission of nociceptive stimuli from the periphery into the spinal marrow (Passmore et al., J. Neurosci. 2003; 23(18): 7227-36).
It has accordingly been possible to detect an analgesic activity in preclinical neuropathy and inflammatory pain models for the KCNQ2/3 agonist retigabine (Blackburn-Munro and Jensen, Eur J Pharmacol. 2003; 460(2-3); 109-16; Dost et al., Naunyn Schmiedebergs Arch Pharmacol 2004; 369(4): 382-390).
The KCNQ2/3 K+ channel thus represents a suitable starting point for the treatment of pain; in particular of pain selected from the group consisting of chronic pain, acute pain, neuropathic pain, inflammatory pain, visceral pain and muscular pain (Nielsen et al., Eur J Pharmacol. 2004; 487(1-3): 93-103), in particular of neuropathic and inflammatory pain. Moreover, the KCNQ2/3 K+ channel is a suitable target for therapy of a large number of further diseases, such as, for example, migraine (US2002/0128277), cognitive diseases (Gribkoff, Expert Opin Ther Targets 2003; 7(6): 737-748), anxiety (Korsgaard et al., J Pharmacol Exp Ther. 2005, 14(1): 282-92), epilepsy (Wickenden et al., Expert Opin Ther Pat 2004; 14(4): 457-469; Gribkoff, Expert Opin Ther Targets 2008, 12(5): 565-81; Miceli et al., Curr Opin Pharmacol 2008, 8(1): 65-74), urinary incontinence (Streng et al., J Urol 2004; 172: 2054-2058), dependency (Hansen et al., Eur J Pharmacol 2007, 570(1-3): 77-88), mania/bipolar disorders (Dencker et al., Epilepsy Behav 2008, 12(1): 49-53) and dystonia-associated dyskinesias (Richter et al., Br J Pharmacol 2006, 149(6): 747-53).
Substituted compounds that have an affinity for the KCNQ2/3 K+ channel are e.g. known from the prior art (WO 2008/046582, WO 2010/046108, WO 2002/066036).
There is a demand for further compounds having comparable or better properties, not only with regard to affinity to KCNQ2/3 K+ channels 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. A weak or non-existent interaction with transporter molecules, which are involved in the ingestion and the excretion of pharmaceutical compositions, is also to be regarded as an indication of improved bioavailability and at most low interactions of pharmaceutical compositions. Furthermore, the interactions with the enzymes involved in the decomposition and the excretion of pharmaceutical compositions should also be as low as possible, as such test results also suggest that at most low interactions, or no interactions at all, of pharmaceutical compositions are to be expected.
In addition, it may be advantageous if the compounds show a high selectivity towards other receptors of the KCNQ family (specificity), e.g. towards KCNQ1, KCNQ3/5 or KCNQ4. A high selectivity may have a positive effect on the side effects profile: for example it is known that compounds which (also) have an affinity to KCNQ1 are likely to have a potential for cardial side effects. Therefore, a high selectivity towards KCNQ1 may be desirable. However, it may also be advantageous for the compounds to show a high selectivity towards other receptors. For instance, it may be advantageous for the compounds to show a low affinity for the hERG ion channel or the L-type calcium ion channel (phenylalkylamine-, benzothiazepin-, dihydropyridine-binding site) since these receptors are known to possibly have a potential for cardial side effects. Further, an improved selectivity towards binding to other endogenic proteins (i.e. receptors or enzymes) may result in a better side effects profile and, consequently to an improved tolerance.
It was therefore an object of the invention to provide new compounds having advantages over the compounds of the prior art. These compounds should be suitable in particular as pharmacological active ingredients in pharmaceutical compositions, preferably in pharmaceutical compositions for the treatment and/or prophylaxis of disorders and/or diseases which are mediated, at least in part, by KCNQ2/3 K+ channels.
That object is achieved by the subject-matter described herein.
It has been found, surprisingly, that substituted compounds of the general formula (I) given below are suitable for the treatment of pain. It has also been found, surprisingly, that substituted compounds of the general formula (I) given below also have an excellent affinity for the KCNQ2/3 K+ channel and are therefore suitable for the prophylaxis and/or treatment of disorders and/or diseases that are mediated at least in part by KCNQ2/3 K+ channels. The substituted compounds thereby act as modulators, i.e. agonists or antagonists, of the KCNQ2/3 K+ channel.
The present invention therefore relates to a substituted compound of general formula (I),

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 substituted (2nd generation substituents). Depending on the definition, these substituents of the substituents can for their part be re-substituted (3rd generation substituents). If, for example, R1 is = a C1-10 aliphatic residue (1st generation substituent), then the C1-10 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═(C1-10 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═C1-10 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 R7 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.

Pharmacological Experiments
Method I. Fluorescence Assay Using a Voltage Sensitive Dye (Fluorimetry)
The modulation of the KCNQ opening state (and consequently the voltage potential of a cell) by test compounds such as compounds according to the present invention results in an increased or reduced amount of a voltage-sensitive dye in the cytoplasm of the cells tested. These voltage-sensitive dyes are fluorescent dyes and, therefore, are forming the link between cell potential influenced by KCNQ modulation and fluorescence intensity. A KCNQ agonist leads to an opening of the channel, potassium and dye efflux, a following hyperpolarization and a reduction of the inner fluorescence intensity in a kinetic protocol. If applying an ion jump by KCl depolarization, KCNQ agonists increase the ΔF/F value. An antagonist performs vice versa, respectively.
The ‘fluorimetry EC50’ is the half maximum effective concentration (EC50), where the concentration of a drug/compound induces a response halfway between the baseline and maximum plateau effect. In other words, said value represents the concentration of a compound, where 50% of its maximal effect in the fluorimetric assay is observed if the substance concentration is graphed against the corresponding ΔF/F values (for which the calculation method is described below). Therefore, ‘fluorimetry EC50’ is a measure for the compound potency. The compound efficacy is mirrored by ‘fluorimetry % efficacy’ (‘% Efficacy’) and refers to the maximum response achievable by the test compound, i.e. the plateau effect. This drug's plateau effect is related to the plateau effect, which can be achieved by applying a saturated concentration of a reference compound, e.g. Retigabine (50 μM), in independent wells of the same experimental plate or series. A compound showing 100% efficacy is as efficacious as the reference compound (Retigabine) with a saturated concentration. This calculation ‘% Efficacy’ method was introduced in order to normalize the ΔF/F values of different experiments to a common comparator compound, and make the test drug effects comparable.
Human CHO-K1 cells expressing KCNQ2/3 channels are cultivated adherently at 37° C., 5% CO2 and 95% humidity in cell culture bottles (e.g. 80 cm2 TC flasks, Nunc) with DMEM-high glucose (Sigma Aldrich, D7777) including 10% FCS (PAN Biotech, e.g. 3302-P270521) or alternatively MEM Alpha Medium (1×, liquid, Invitrogen, #22571), 10% fetal calf serum (FCS) (Invitrogen, #10270-106, heat-inactivated) and the necessary selection antibiotics.
Before being sown out for the measurements, the cells are washed with 1× DPBS buffer Ca2+/Mg2+-free (e.g. Invitrogen, #14190-094) and detached from the bottom of the culture vessel by using Accutase (PAA Laboratories, #L11-007) (incubation with Accutase for 15 min at 37° C.). The cell number is determined using a CASY™ cell counter (TCC, Schärfe System). Depending on the optimal density for each individual cell line, 20,000-30,000 cells/well/100 μl are seeded onto 96-well Corning™ CellBIND™ assay plates (Flat Clear Bottom Black Polystyrene Microplates, #3340). Freshly seeded cells are then left to settle for one hour at room temperature, followed by incubation for 24 hours at 37° C., 5% CO2 and 95% humidity.
The voltage-sensitive fluorescent dye from the Membrane Potential Assay Kit (Red™ Bulk format part R8123 for FLIPR, MDS Analytical Technologies™) is prepared by dissolving the contents of one vessel Membrane Potential Assay Kit Red Component A in 200 ml of extracellular buffer (ES buffer, 120 mM NaCl, 1 mM KCl, 10 mM HEPES, 2 mM CaCl2, 2 mM MgCl2, 10 mM glucose; pH 7.4). After removal of the nutrient medium, the cells are washed once with 200 μl of ES buffer, then loaded for 45 min at room temperature in 100 μl of dye solution in the dark.
Fluorescence measurements are carried out in a BMG Labtech FLUOstar™, BMG Labtech NOVOstar™ or BMG Labtech POLARstar™ instrument (525 nm excitation, 560 nm emission, Bottom Read mode). After incubation with the dye, 50 μl of the test substances in the desired concentrations, or 50 μl of ES buffer for control purposes, are applied to the wells of the assay plate and incubated for 30 min at room temperature while being shielded from light. The fluorescence intensity of the dye is then measured for 5 min and the fluorescence value F1 of each well is thus determined at a given, constant time. 15 μl of a KCl solution are then added to each well (final concentration of potassium ions 92 mM). The change in fluorescence intensity is subsequently monitored until all the relevant values have been obtained (mainly 5-30 min). At a given time post KCl application, a fluorescence value F2 is determined, in this case at the time of the fluorescence peak.
For calculation, the fluorescence intensity F2 is corrected for the fluorescence intensity F1, and the activity (ΔF/F) of the target compound on the potassium channel is determined as follows:

of control wells.
is determined by adding to the well only the buffer solution instead of the test substance, determining the value F1K of the fluorescence intensity, adding the potassium ions as described above, and measuring a value F2K of the fluorescence intensity. F2K and F1K are then calculated as follows:

Calculations of EC50 and IC50 values are carried out with the aid of ‘Prism v4.0’ software (GraphPad Software™)
Method II. Low-Intensity Tail Flick Test (Rat)
In the low-intensity tail flick test, the determination of the antinociceptive effect of the compounds according to the invention towards an acute noxious thermal stimulus is carried out by measuring the withdrawal reflex of the rat tail (tail flick) in response to a radiant heat beam (analgesia meter; model 2011 of the company Rhema Labortechnik, Hofheim, Germany) according to the method described by D'Amour and Smith (J. Pharm. Exp. Ther. 72, 74 79 (1941). To this end, the rats were placed in a plexiglas restrainer, and a low-intensity radiant heat beam (48° C.) was focused onto the dorsal surface of the tail root. The stimulus intensity was adjusted to result in a mean pre-drug control withdrawal latency of about 7 s, thus also allowing a supraspinal modulation of the spinally mediated acute nociceptive reflex. A cutoff time of 30 s was applied to avoid tissue damage. Male Sprague-Dawley rats (Janvier, Le Genest St. Isle, Frankreich) with weights of 200-250 g were used. 10 rats were used per group. Before administration of a compound according to the invention, the animals were pre-tested twice in the course of five minutes and the mean of these measurements was calculated as the pre-test mean. The antinociceptive effect was determined at 20, 40 and 60 min after peroral compound administration. The antinociceptive effect was calculated based on the increase in the tail withdrawal latency according to the following formula and is expressed as percentage of the maximum possible effect (MPE [%]):
MPE=[(T1−T0)/(T2−T0)]*100
In this, T0 is the control latency time before and T1 the latency time after administration of the compound, T2 is the cutoff time and MPE is the maximum possible effect. Employing variant analysis (repeated measures ANOVA) allowed testing of statistically significant differences between the compounds according to the invention and the vehicle group. The significance level was set to p≦0.05. To determine the dose dependency, the particular compound according to the invention was administered in 3-5 logarithmically increasing doses, including a threshold dose and a maximum effective dose, and the ED50 values were determined with the aid of regression analysis. The ED50 calculation was performed at the time of maximum efficacy (usually 20 min after administration of the compounds).
