Substituted 4-aminocyclohexanols

FIELD OF THE INVENTION

[0002] The present invention relates to substituted 4-aminocyclohexanols, to methods of producing them, to pharmaceuticals containing these compounds, to the use of substituted 4-aminocyclohexanols for producing pharmaceutical compositions for the treatment of various indications, in particular pain, and for related treatment methods.

BACKGROUND OF THE INVENTION

[0003] The heptadecapeptide nociceptin is an endogenous ligand of the ORL1 (Opioid-Receptor-Like) receptor (Meunier et al., Nature 377, 1995, pp. 532-535), which belongs to the family of opioid receptors and may be found in many regions of the brain and the spinal cord (Mollereau et al., FEBS Letters, 341, 1994, pp. 33-38, Darland et al., Trends in Neurosciences, 21, 1998, pp. 215-221). The peptide is characterized by a high affinity, with a Kd value of approximately 56 pM (Ardati et al., Mol. Pharmacol. 51, pp. 816-824), and by high selectivity for the ORL1 receptor. The ORL1 receptor is homologous to the μ, κ and δ opioid receptors and the amino acid sequence of the nociceptin peptide has a marked similarity to those of the known opioid peptides. The activation of the receptor induced by the nociceptin leads, via the coupling with Gi/o proteins to inhibition of the adenylate cyclase (Meunier et al., Nature 377, 1995, pp. 532-535). On the cellular plane also, there are functional similarities between the μ, κ and δ opioid receptors and the ORL1 receptor with respect to activation of the potassium channel (Matthes et al., Mol. Pharmacol. 50, 1996, pp. 447-450; Vaughan et al., Br. J. Pharmacol. 117, 1996, pp. 1609-1611) and inhibition of the L-, N- and P/Q-type calcium channels (Conner et al., Br. J. Pharmacol. 118, 1996, pp. 205-207; Knoflach et al., J. Neuroscience 16, 1996, pp. 6657-6664).

[0004] After intercerebroventicular application, the nociceptin peptide exhibits pronociceptive and hyperalgesic activity in various animal models (Reinscheid et al., Science 270, 1995, pp. 792-794; Hara et al., Br. J. Pharmacol. 121, 1997, pp. 401-408). These findings may be explained as inhibition of stress-induced analgesia (Mogil et al., Neurosci. Letters 214, 1996, pp. 131-134; and also Neuroscience 75, 1996, pp. 333-337). In this connection, anxiolytic activity of the nociceptin could also be demonstrated (Jenck et al., Proc. Natl. Acad. Sci. USA 94, 1997, 14854-14858).

[0005] On the other hand, an antinociceptive effect of nociceptin could be demonstrated in various animal models, in particular after intrathecal administration. Nociceptin inhibits the activity of kainate- or glutamate-stimulated dorsal root ganglion neurons (Shu et al., Neuropeptides, 32, 1998, 567-571) or glutamate-stimulated spinal cord neurons (Faber et al., Br. J. Pharmacol., 119, 1996, pp. 189-190); it has an antinociceptive effect in the tail flick test in mice (King et al., Neurosci. Lett., 223, 1997, 113-116), in the flexor-reflex model in rats (Xu et al., NeuroReport, 7, 1996, 2092-2094) and in the formalin test on rats (Yamamoto et al., Neuroscience, 81, 1997, pp. 249-254). In models of neuropathic pain, an antinociceptive effect of nociceptin, which is of interest in so far as the effectiveness of nociceptin increases after axotomy of spinal nerves, could be demonstrated (Yamamoto and Nozaki-Taguchi, Anesthesiology, 87, 1997). This is in contrast to conventional opioids, of which the effectiveness decreases under these conditions (Abdulla and Smith, J. Neurosci., 18, 1998, pp. 9685-9694).

[0006] The ORL1 receptor also participates in the regulation of further physiological and pathophysiological processes. These include learning and memory formation (Sa{dot over (n)}din et al., Eur. J. Neurosci., 9, 1997, pp. 194-197; Manabe et al., Nature, 394, 1997, pp. 577-581), hearing ability (Nishi et al., EMBO J., 16, 1997, pp. 1858-1864), assimilation of food (Pomonis et al., NeuroReport, 8, 1996, pp. 369-371), regulation of blood pressure (Gumusel et al., Life Sci., 60, 1997, pp. 141-145; Campion and Kadowitz, Biochem. Biophys. Rep. Comm., 234, 1997, pp. 309-312), epilepsy (Gutierrez et al. Abstract 536.18, Society for Neuroscience, Vol. 24, 28th Ann. Meeting, Los Angeles, 7-12 Nov. 1998) and diuresis (Kapisa et al., Life Sciences, 60, 1997, PL 15-21). In an article by Calo et al. (Br. J. Pharmacol., 129, 2000, 1261-1283) an overview is given of the indications or biological processes in which the ORL1 receptor plays a part or could very probably play a part. These include: analgesia, stimulation and regulation of food assimilation, influence on μ agonist such as morphine, treatment of withdrawal symptoms, reduction of addiction potential of morphines, anxiolysis, modulation of movement activity, memory defects, epilepsy; modulation of neurotransmitter discharge, in particular of glutamate, serotonin and dopamine, and therefore neurodegenerative diseases; influencing of the cardiovascular system, triggering of an erection, diuresis, antinatriuresis, electrolyte management, arterial blood pressure, water retention diseases, intestinal motility (diarrhea), relaxing effects on the respiratory tracts, micturation reflex (urinary incontinence). The use of agonist and antagonist as anoretics, analgesics (also in co-administration with opioids) or nootropics, but also as antitussives is also discussed.

[0007] The possible applications of compounds which bind to the ORL1 receptor and activate or inhibit it are correspondingly varied.

EXAMPLES

[0570] The following examples show compounds according to certain embodiments of the invention and the preparation thereof and efficacy tests carried out therewith.

[0571] In general the following details apply:

[0572] The chemicals and solvents used were acquired commercially from conventional suppliers (Acros, Avocado, Aldrich, Fluka, Lancaster, Maybridge, Merck, Sigma, TCI etc.) or synthesized.

[0573] Analyses were made by NMR spectroscopy, optionally combined with other methods of analysis such as thin-layer chromatography, mass spectrometry or HPLC.

Example 1

[0574] General Method of Producing Compounds According to the Invention

[0575] The compounds are produced, starting from a cyclohexane-1,4-dione corresponding to formula II suitably protected as, for example, monoacetal. A protected N-substituted 1-amino-4-oxo-cyclohexane carbonitrile compound corresponding to formula III is obtained by reaction with potassium cyanide in the presence of a secondary amine.

[0576] The reaction of the aminonitrile corresponding to formula III with organometallic reagents, preferably Grignard or organolithium reagents, results in substitution of the nitrile function, so a 4-substituted 4-aminocyclohexanone compound corresponding to formula IV is obtained after subsequently removing the carbonyl protective group.

[0577] Intermediates corresponding to formula IV may finally be converted into 4-aminocyclohexanols corresponding to formula I according to the invention by addition of organometallic reagents, preferably Grignard organolithium reagents.

Example 2

[0578] Measurement of the ORL1 Bond

[0579] The 4-aminocyclohexanols corresponding to formula I were investigated in a receptor binding assay with 3H-nociceptin/Orphanin FQ with membranes of recombinant CHO—ORL1 cells. This test system was carried out by the method presented by Ardati et al. (Mol. Pharmacol., 51, 1997, pp. 816-824). The concentration of 3H-nociceptin/Orphanin FQ was 0.5 nM in these tests.

[0580] The binding assays were carried out with 20 μg membrane protein per 200 μl mixture in 50 mM Hepes, pH 7.4, 10 mM MgCl2 and 1 mM EDTA respectively. Binding to the ORL1 receptor was determined using 1 mg WGA-SPA beads (Amersham-Pharmacia, Freiburg), respectively, by incubation of the mixture for one hour at ambient temperature and subsequent measurement in the Trilux scintillation counter (Wallac, Finland). The affinity is indicated as the Ki value.

[0581] The affinity to the ORL1 receptor was determined according to the specified molecular-pharmacological investigations in each of the following examples 4 to 12. The corresponding Ki values are given in the following table 1.

Example 3

[0582] Analgesia Test by the Tail-flick Test on Mice

[0583] The analgesic effectiveness of the compounds according to the invention was investigated in the focal ray (tail-flick) test on mice by D'Amour and Smith's method (J. Pharm. Exp. Ther. 72, 74 79 (1941)). NMRI mice weighing between 20 and 24 g were used for this purpose. The animals were placed individually in specific test cages and the tail base was exposed to a focused ray of heat from an electric lamp (Tail-flick Typ 55/12/10.f1, Labtec, Dr. Hess). The intensity of the lamp was adjusted such that the time from the switching on of the lamp to the sudden jerking away of the tail (latency of pain) was 3 to 5 seconds in untreated animals. Prior to administration of a compound according to the invention, the animals were pre-tested twice within five minutes and the average value of these measurements was calculated as the pre-test average. The pain was measured 20, 40 and 60 min after intravenous administration. The analgesic effect was determined as an increase in the latency of pain (% MPE) by the following formula:

[(T1−T0)/(T2−T0)]×100.

[0584] To is the latency time before application of the substance, T1 the latency time after application and T2 the maximum exposure time (12 sec).

[0585] To determine the dose dependency, the respective compound according to the invention was applied in 3 to 5 logarithmically increasing doses, which each concluded the threshold and the maximum active dose, and the ED50 values were determined by regression analysis. The ED50 was calculated at the peak of action 20 minutes after intravenous administration of the substance.

[0586] The investigated compounds according to the invention exhibited a pronounced analgesic effect. The results are compiled in the following table.
