- the parenteral application can be bypassing a resorption step (e.g. intravenous, intraarterial, intracardial, intraspinal or intralumbal) or by switching on absorption (e.g. intramuscular, subcutaneous, intracutaneous or intraperitoneal).
- Suitable forms of application for parenteral administration include: Injection and infusion preparations in the form of solutions, suspensions, emulsions, lyophilisates and sterile powders.
- L inhalation drug forms including powder inhalers, nebulizers
- nasal drops / solutions sprays, lingual, sublingual or buccal tablets or capsules to be applied
- suppositories e.g., suppositories, ear and eye preparations
- vaginal capsules e.g., aqueous suspensions (lotions, shake mixes), lipophilic suspensions , Ointments, creams, milk, pastes, powder, implants or stents.
- the active compounds can be converted into the administration forms mentioned in a manner known per se. This is done using inert, non-toxic, pharmaceutically suitable excipients. These include carriers (e.g. microcrystalline cellulose), solvents (e.g. liquid polyethylene glycols), emulsifiers (e.g. sodium dodecyl sulfate), dispersants (e.g. polyvinylpyrrolidone), synthetic and / or natural biopolymers (e.g. albumin), stabilizers (e.g. antioxidants such as ascorbic acid), colorants (e.g. inorganic pigments such as iron oxides) or flavorings and / or odors.
- carriers e.g. microcrystalline cellulose
- solvents e.g. liquid polyethylene glycols
- emulsifiers e.g. sodium dodecyl sulfate
- dispersants e.g. polyvinylpyrrolidone
- synthetic and / or natural biopolymers
- the amount is about 0.001 to 100 mg kg, preferably about 0.005 to 30 mg / kg body weight.
- Device type MS Micromass ZQ
- Device type HPLC Waters Alliance 2790; Column: Uptisphere C 18, 50 mm x 2.0 mm, 3.0 ⁇ m; Eluent B: acetonitrile + 0.05% formic acid, eluent A: water + 0.05% formic acid; Gradient: 0.0 min 5% B ⁇ 2.0 min 40% B ⁇ 4.5 min 90% B ⁇ 5.5 min 90% B; Oven: 45 ° C; Flow: 0.0 min 0.75 ml / min - »4.5 min 0.75 ml / min ⁇ 5.5 min 1.25 ml / min; UV detection: 210 nm.
- the P2X receptor is a ligand-activated ion channel. Binding of the agonist ATP leads to activation of the P2X receptor, opening of the ion channel and influx of extracellular calcium into the cell. This calcium influx is measured using the calcium-sensitive photoprotein aequorin.
- a recombinant CHO cell line Choinese hamster ovary cells with constitutive expression of the human P2X 4 receptor and of apoaequorin was produced.
- the CHO cells are sown 1-2 days beforehand on microtiter plates in 96-, 384- or 1536-well format, depending on the used microtiter plate format with 5000 (96 format), 2000 (384- Format) or 500 (1536 format) cells per well.
- the cell culture medium is removed and the cells are incubated for 4 hours in physiological saline (Tyrode buffer) with 5 ⁇ g / ml coelenterazine. Test substances are added 5 minutes before the actual experiment.
- ATP is then added in a concentration of 1-2 ⁇ M and the ATP-induced calcium signal is measured in a luminometer as aequorin luminescence.
- Substances with antagonistic activity at the P2X receptor can inhibit the ATP-induced calcium signal either by interference with the binding of ATP to the P2X 4 receptor, by preventing the opening of the channel or by blocking the influx of calcium through the opened channel.
- Embodiments 1-3 show ICsn values of 0.5, 2 and 0.6 ⁇ M in this test.
- ROS oxygen radical formation
- the assay is performed in Hank's Balanced Salt Solution (HBSS) to which 10 mM glucose is added.
- Monocytes are e.g. isolated using the "Becton Dickinson Vacutainer System” as described by the manufacturer and suspended in HBSS.
- HRPO Horse Radish Peroxidase
- luminol 50 ⁇ M final concentration
- HRPO 10 U / ml final concentration
- Test batch ATP (100 ⁇ M final concentration) added. The final volume in the test batch is 200 ul. Immediately after adding ATP, the ROS formation is monitored with a microplate lumino meter over a period of 120 seconds.
- Monocytes are isolated from blood using standard methods. The chemotaxis of the monocytes is observed in a Transwell system [CC Bleul et al., J. Exp. Med. 184: 1101-1109 (1996)].
- the membrane used (3 ⁇ m pore size, polyethylene terephthalate, Falcon) is first coated with fibronectin. 10 5 monocytes in RPMI 1640 medium are added to the upper chamber.
- the lower chamber contains varying concentrations of stimulus or constant stimulus concentration (500 ⁇ M ATP or 10 nM MCP-1) and varying concentrations of the test substance.
- the substances to be examined are in both chambers.
- the test mixture is incubated for 3 h at 37 ° C. and 5% CO 2 [W. Falk et al., J. Immunol. Methods 38: 239-247 (1980)]. After the incubation, the cells that have migrated to the lower chamber are determined.
- the compounds according to the invention can be converted into pharmaceutical preparations as follows:
- Example 1 100 mg of the compound from Example 1, 50 mg lactose (monohydrate), 50 mg corn starch (native), 10 mg polyvinylpyrrolidone (PVP 25) and 2 mg magnesium stearate.
- a single dose of 100 mg of the compound according to the invention corresponds to 10 ml of oral suspension.
- Rhodigel is suspended in ethanol, the active ingredient is added to the suspension. The water is added with stirring. The swelling of the Rhodigel is stopped for about 6 hours.
