Abstract

The present application relates to compounds of formula (I), wherein R1 to R5 are as defined in claim 1, a pharmaceutical composition thereof and said compounds for use in the treatment of diseases related with the activity of P2X7 receptor.

Description

FIELD OF THE INVENTION
The présent invention is directed to novel compounds which inliibit the P2X7 receptor. Separate aspects of the invention are directed to pharmaceutical compositions comprising said compounds and uses of the compounds to treat pain, inflammation, neurological disorders, or neuropsychiatrie disorders.
BACKGROUND ART
The purinergic 2X7 (P2X7) receptor is a ligand-gated ion channel which is activated by extracellular ATP and is présent on a variety of cell types, including microglia in the central nervous system and other cells involved in inflammation and immune system fonction. The P2X? receptor has been shown to hâve a rôle in cytolysis in the immune system (Surprenant, et al. Science, 272,735-41,1996), and is involved in activation of lymphocytes and monocyte/macrophages leading to the increased release of pro-inflammatory cytokines (e.g., TNFa and ILl β) from these cells (Ferrari, et al. Neurophannacol, 36,1295-301,1997).
Studies hâve shown that inhibiting P2X7 receptor activation in situations of inflammation (e.g., rheumatoid arthritis and other autoimmune diseases, osteoarthritis, astlima, clironic obstructive pulmonary disease and inflammatory bowel disease) or interstitial fibrosis results in a therapeutic effect (DiVirgilio, et al. Drug Dev Res, 45,207-13, 1998). These and other studies indicate that P2X7 receptor antagonîsts may find use in the treatment and prophylaxis of pain, including acute, chronic and neuropathie pain (Chessel, et al, Pain, 114,386-96,2005).
Inhibiting P2X7 activation may also diminish or reduce cell death caused by prolongation of activated P2X7 receptors, indicating a potential therapeutic intervention for said antagonîsts in nervous system injury or degeneration (Sperlagli, et al., Progress in Neurobiology, 7, 327-346, 2006). Vianna, et al. (Epîlepsia, 43, 27-229, 2002) also revealed a potential rôle for P2X7 receptors in the pathogenesis of epilepsy. Interestingly, because of the P2X7 receptor’s rôle in microglia activation and prolifération in the central nervous system (CNS), a self-propagating cycle of neuroinflammation and neurodegeneration results from P2X7 receptor activation in areas of the brain (Monif, et al, J Neurosci, 29,3781-91,2009).
Thus, P2X7 receptor antagonists, particularly small molécules with sufficient brain-penetrable properties, are désirable as useful agents for therapeutic intervention in the central nervous system for treating pain, inflammation, neurological and neurodegenerative disorders, neuropsychiatrie disorders, or other disorders for which the réduction or otherwise stabilization of pro-inflammatory cytokines is bénéficiai. The présent invention fulfills this need, and provides further related advantages.
SUMMARY QF THE INVENTION
An objective of the présent invention is to provide compounds that inhibit P2X7 receptors.
Accordingly, the présent invention relates to compounds of Formula I.

Example 5 P2 X7 binding ass ay
This example illustrâtes représentative assays for use in evaluating the test compounds for antagonist activity. Compounds of tlie présent invention were tested in vitro for their ability to act as antagonists to tlie P2X7 receptor.
Screening assays to détermine P2X7 receptor antagonism are well known to the person skilled in tlie art. Functional assays, such as second messenger assays, and cytokine measurement assays done in vitro are also well known În tlie art and may be used to assess tlie spécifie binding and cellular activity of P2X7 receptor compounds.
In vitro assay example
Cell culture: 293 HEK cells, stably transfected with plasmids capable of expressing human P2X7 receptor, were cultured by standard methods. Cells were plated to cell density of approximately 15,000 cells/well in 384-xvell assay plates (50 μΙ/well) with 1,5% low sérum media (DMEM, 1.5% BCS, 1% L-glut (2 mM), 1%P/S).
293 HEK cells, stably transfected with plasmids capable of expressing rat or mouse P2X7 receptor, were cultured by standard methods. Cells were plated to cell density of approximately 15,000 cells/well in 384-well assay plates (50 μΙ/well) with 1.5% low sérum media (DMEM, 1.5% FBS, 1% L-glut (2 mM), 10 mM HEPES, 1% P/S). Cells were plated 24 hours prior to assay. Cells expressing human, rat or mouse P2X7 receptor were assayed in the following manner.
Fluorescent Imaging Plate Reader (FLIPR) assay: Briefly, 293-human or mouse P2X7 stable cells were incubated in sucrose buifer, pH 7.4 [KC1 (5 mM), NaH2PO4.2H2O (9.6 mM), HEPES (25 mM), sucrose (280 mM), glucose (5 mM), CaCl2 (0.5 mM), and probenecid (0.1425 g in 3 mL IN NaOH was added for 500 mL solution)] in 384-well plates.
293-rat P2X7 stable cells were incubated in HHPB (pH 7.4) [consisting of Hank’s BSS (IX); HEPES (pH 7.4) (20 mM) (Sigma); probenecid (0.710 g/5 mL IN NaOH) (Sigma); and BSA (0.05%) (Roche) which was added after the pH had been adjusted] in 384-well plates. Fluo-4 NW dye mix (Molecular
Probes, Inc., Eugene, OR, USA) was prepared in buffer (see manufacturer^ instructions). Cell plates were removed from the 37 °C incubator, tlie media discarded and then 30 pL of dye was added to each
165 well. Plates were placed in the 37 °C, non-CÛ2 incubator for 30 minutes and then room température for 30 minutes.
Two sets of drug plates were prepared: A) Mixtures of compound plus agonist were prepared as follows, in order to déterminé dose response: BzATP: 11 point 1/2 log, diluted in buffer, starting from 1 mM. Testing compounds: 11 point 1/2 log, diluted in 2% DMSO buffer starting from 10 μΜ. B) Agonist only mixture was prepared with BzATP at a single concentration in buffer (concentration determined by dose response).
Compound mixtures (A) were added to assay plates containing cells and placed at room température for 30 minutes, then BzATP (B) was added. Fluorescence was rend using the Tetra FLIPR® (Molecular Devices, Inc., Sunnyvale, CA, USA) and IC50 values were calculated by standard methods to détermine antagonist activity.
Assay for stimulating IL!β release from THP-1 cells: THP-1 cells (The Global Bioresource Center, ATCC #: TIB-202™) were differentiated by incubation with 10 ng/mL IFN-gamma (Sigma, Cat#: 13265) in Tl 50 plates, at a cell density of 0.5 E6cells/mL, in RPMI1640 media (ATCC, Cat# 30-2001) with 10% FBS and 1% P/S for 48 hours. The cells then were stimulated with 100 ng/mL LPS (Sigma, Cat#: L4516) in sérum free CTL Test media (Sigma Cat#: CTLT-005), without L-glutamine and antibiotics, for 3 hours. Test compounds (antagonists) were added and incubated for 30 minutes. BzATP (at final concentration of 1 mM) was added and incubated for 30 minutes.
Cell plates were centrifuged at 3000 rpm for 5 minutes and the supematants were immediately collected for AlphaLISA® immunoassay (PerkinElmer Inc., Waltham, MA, USA; Catalog No. AL220C) or aliquoted and stored at < -20°C. The AlphaLISA® immunoassay was performed according to the manufacturées instructions.
