Definitions
- the present invention relates to substituted Tetrahydropyrrolopyrazin- compounds, processes for their preparation, medicaments containing these compounds and the use of these compounds for the preparation of medicaments.
- K + channels of the molecular subtype KCNQ2 / 3 (Kv7.2 / 7.3) are expressed in neurons of different regions of the central (hippocampus, amygdala) and peripheral (dorsal root ganglia) nervous system and regulate their excitability. Activation of KCNQ2 / 3 K + channels leads to hyperpolarization of the cell membrane and concomitant decrease in the electrical excitability of these neurons.
- KCNQ2 / 3-expressing neurons of the dorsal root ganglia are involved in the transmission of nociceptive excitations from the periphery to the spinal cord (Passmore et al., J Neurosci., 2003; 23 (18) 7227-36). Accordingly, for the KCNQ2 / 3 agonist retigabine, analgesic efficacy has been demonstrated in preclinical neuropathy and inflammatory pain models (Blackbum-Munro and Jensen, Eur J Pharmacol., 2003; 460 (2-3): 109-16; Dost et al., Naunyn Schmiedeberg's Arch Pharmacol 2004; 369 (4): 382-390).
- the KCNQ2 / 3K + channel thus provides a suitable starting point for the treatment of pain; in particular pain selected from the group consisting of chronic pain, neuropathic pain, inflammatory pain and muscular pain (Nielsen et al., Eur J Pharmacol. 2004; 487 (1-3): 93-103), especially neuropathic and inflammatory pain represents.
- the KCNQ2 / 3 K + channel is a suitable target for the therapy of a variety of other diseases such as migraine (US2002 / 0128277), cognitive disorders (Gribkoff, Expert Opin Ther Targets 2003; 7 (6): 737-748), 2005, 14 (1): 282-92), epilepsy (Wickenden et al., Expert Opin Ther Pat 2004; 14 (4): 457-469), and urinary incontinence (Strictly et al., J Urol 2004; 172: 2054-2058).
- migraine US2002 / 0128277
- cognitive disorders Gribkoff, Expert Opin Ther Targets 2003; 7 (6): 737-748
- epilepsy Wickenden et al., Expert Opin Ther Pat 2004; 14 (4): 457-469
- urinary incontinence Strictly et al., J Urol 2004; 172: 2054-2058.
- substituted tetrahydropyrrolopyrazine compounds of the general formula I given below are suitable for the treatment of pain and also have an excellent affinity for the KCNQ2 / 3K + channel and are therefore suitable for the treatment of disorders or diseases which are at least partially KCNQ2 / 3 K + channels.

- Human CHO-K1 cells expressing KCNQ2 / 3 channels are transfected into cell culture flasks (eg 80 cm 2 TC flasks, Nunc) with MEM alpha medium (1x, liquid, Invitrogen, # 22571), 10% fetal calcium serum (FCS) (FCS). Invitrogen, # 10270-106, heat inactivated) and the necessary selection antibiotics are cultured adherently at 37 ° C, 5% CO 2 and 95% humidity.
- the cells are washed with a 1 ⁇ DPBS buffer without Ca 2 VMg 2+ (eg Invitrogen, # 14190-094) and detached from the bottom of the culture vessel by means of Accutase (PAA Laboratories, # L11-007) (incubation with Accutase for 15 min at 37 ° C).
- the number of cells then determined is determined using a CASY TM cell counter (Model TCC, Shurfe System) to subsequently transfer 20,000 cells / well / 100 ⁇ l of the described nutrient medium to the 96 well Corning TM CellBIND TM (Fiat Clear Bottom Black Polystyrene Microplates, # 3340). This is followed by a one-hour incubation at room temperature without fumigation or humidity control, followed by a 24 hour incubation at 37 ° C, 5% CO 2 and 95% humidity.
- the voltage-sensitive fluorescent dye from the Membrane Potential Assay Kit (Red TM BuIk format part R8123 for FLIPR, Molecular Devices TM) is prepared by adding the contents of one vessel of Membrane Potential Assay Kit Red Component A to 200 ml of Extracellular Buffer (ES buffer, 120 mM NaCl, 1mM KCl, 10mM HEPES, 2mM CaCl 2 , 2mM MgCl 2 , 10mM glucose, pH 7.4). After acceptance of the Nutrient media, the cells are washed with 200 ul ES buffer, then overlaid with 100 ul of the above dye solution and incubated for 45 min at room temperature under light.
- Extracellular Buffer ES buffer, 120 mM NaCl, 1mM KCl, 10mM HEPES, 2mM CaCl 2 , 2mM MgCl 2 , 10mM glucose, pH 7.4
- the fluorescence measurements are performed with a BMG Labtech FLUOstar TM or BMG Labtech POLARstar TM instrument (525 nm Exation, 560 nm emission, bottom read mode). After the dye incubation, 50 .mu.l of the substances to be tested in the desired concentrations or 50 .mu.l of ES buffer are placed in separate wells of the measuring plate for control and incubated for 30 min at room temperature with the shielding of light. The fluorescence intensity of the dye is then measured for 5 minutes and the fluorescence value Fi of each well is determined at a fixed and constant point in time. Subsequently, 15 ⁇ l of a 100 mM KCl solution (final concentration 92 mM) is added to each well. The change in fluorescence is then measured until all relevant measured values have been obtained (primarily 5-30 min). At a fixed time after KCI application, a fluorescence value F 2 is determined, in this case at the time of the fluorescence peak.
- the fluorescence intensity F 2 is compared with the fluorescence intensity Fi and from this the agonistic activity of the target compound on the potassium channel is determined.
- F 2 and Fi are charged as follows:
- F with - are compared by control cells. - is determined by IF) ⁇ VF) ⁇ to the reaction mixture instead of the substance to be tested only the buffer solution is added, determines the value F 1K of the fluorescence intensity, adding the potassium ions as described above and a value F 2K measures the fluorescence intensity. Then F 2 K and Fi «are calculated as follows: A substance has an agonistic activity on the potassium channel when
- AF target connection is an increase of - to observe.
- mice weighing 16-18g are treated with three loose ligatures of the right nervus ischiaticus under Ketavet-Rompun anesthesia.
- the animals develop hypersensitivity to the paw innervated by the damaged nerve, which is quantified after a recovery period of one week for about four weeks using a 4 ° C cold metal plate (cold allodynia). The animals will be for one
- Period of 2 min. observed on this plate and the number of pull-out reactions of the injured paw is measured. Based on the Preoperative value before substance application, the substance effect over a period of one hour at four time points (eg, 15, 30, 45, 60 minutes after application) determines and the resulting area under the curve (AUC) and the inhibition of cold allodynia to the individual Measurement points expressed in percent effect on vehicle control (AUC) or on the initial value (single measurement points).
- Example 2 the activity of Example 2 was tested in the Bennett model (i.v.- application). At a dosage of 10 mg / kg, 40% MPE was measured.
- mice Male Sprague Dawley rats (140-16Og) from a commercial breeder (Janvier, Genest St. Isle, France) were kept under a 12: 12h light-dark rhythm. The animals were kept ad libitum with food and tap water. Between the delivery of the animals and the operation a break of one week was kept. The animals were repeatedly tested after surgery for a period of 4-5 weeks, with a washout of at least one week was observed.
- Example 2 the activity of Example 2 was tested in the Chung model (iv application). ED 50 of 2.8 mg / kg was determined.
- the stationary phase used for the column chromatography was silica gel 60 (particle size 0.040-0.063 mm) from E. Merck, Darmstadt.
- PS diimide a polymer bound carbodiimide having the following structure Loading: 0.9-1.4 mmol / g particle size: 75-150 ⁇ m
