The present invention relates to novel benzamide inhibitors of the P2X7 receptor, processes for their preparation, intermediates useful in their preparation, pharmaceutical compositions containing them, and their use in therapy. The active compounds of the present invention are useful in the treatment of inflammatory diseases such as osteoarthritis and rheumatoid arthritis; allergies, asthma, COPD, cancer, reperfusion or ischemia in stroke or heart attack, autoimmune diseases and other disorders. The active compounds are also antagonists of the P2X7 receptor.

The P2X7 receptor (previously known as P2Z receptor), which is a ligand-gated ion channel, is present on a variety of cell types, largely those known to be involved in inflammatory/immune process, specifically, macrophages, mast cells and lymphocytes (T and B). Activation of the P2X7 receptor by extracellular nucleotides, in particular adenosine triphosphate, leads to the release of interleukin-1 β (IL-Ιβ) and giant cell formation (macrophages/microglial cells), degranulation (mast cells) and proliferation (T cells), apoptosis, and L-selectin shedding (lymphocytes). P2X7 receptors are also located on antigen-presenting cells (APC), keratinocytes, salivary acinar cells (parotid cells), hepatocytes and mesangial cells. P2X7 antagonists are known in the art, such as those described in International Patent Publications WO 01/46200, WO 01/42194, WO 01/44213, WO99/29660, WO 00/61569, WO 99/29661, WO 99/29686, WO 00/71529, and WO 01/44170, as well as in USSN 60/336,781 (corresponding to International Patent Publication No. WO 03/042191).

Benzamides, heteroarylamides and reverse amides for uses other than inhibition of the P2X7 receptor are described in various publications, such as International Patent Publications WO 97/22600, EP 138,527, WO 00/71509, WO 98/28269, WO 99/17777 and WO 01/58883.

PHARMACOLOGICAL ANALYSIS

Certain compounds such as benzoyl benzoyl adenosine triphosphate (bbATP) are known to be agonists of the P2X7 receptor, effecting the formation of pores in the plasma membrane (Drug Development Research (1996), 37(3), p. 126). Consequently, when the 5 receptor is activated using bbATP in the presence of ethidium bromide (a fluorescent DNA probe), an increase in the fluorescence of intracellular DNA-bound ethidium bromide is observed. Alternatively, the propidium dye YOPRO-1 can be substituted for ethidium bromide so as to detect uptake of the dye. The increase in fluorescence can be used as a measure of P2X7 receptor activation and therefore to quantify the effect of a compound on the P2X7 10 receptor. in this manner, the compounds of the invention can be tested for antagonist activity at the P2X7 receptor. 96-Well flat bottomed microtitre plates are filled with 250 pi of test solution comprising 200 pi of a suspension of THP-1 cells (2.5 x 106 cells/ml, more preferably prestimulated as described in the literature with a combination of LPS and TNF to promote 15 receptor expression) containing lO^M ethidium bromide, 25 pi of a high potassium, low sodium buffer solution (10mM Hepes, 150 mM KCI, 5 mM D-glucose and 1.0% FBS at pH 7.5) containing 10'5M bbATP, and 25 pi of the high potassium'buffer solution containing 3 x 10'5M test compound (more preferably 5 x 10^M, more preferably 1 x lO^M.more preferably 1 x 1O^M). The plate is covered with a plastic sheet and incubated at 37°C for one hour. The 20 plate is then read in a Perkin-Elmer fluorescent plate reader, excitation 520 nm, emission 595 nm, slit widths: Ex 15 nm, Em 20 nm. For the purposes of comparison, bbATP (a P2X7 receptor agonist) and pyridoxal 5-phosphate (a P2X7 receptor antagonist) can be used separately in the test as controls. From the readings obtained, a plC50 figure can be calculated for each test compound, this figure being the negative logarithm of the 25 concentration of test compound necessary to reduce the bbATP agonist activity by 50%.

In like manner, the compounds of the invention can be tested for antagonist activity at the P2X7 receptor using the cytokine IL-1 β as the readout. Blood collected from normal volunteers in the presence of heparin is fractionated using lymphocyte separation medium obtained from Organon Technica (Westchester, PA). The region of the resulting gradient 30 containing banded mononuclear cells is harvested, diluted with 10 ml of Maintenance Medium (RPMI 1640, 5% FBS, 25 mM Hepes, pH 7.2, 1% penicillin/streptomycin), and cells are collected by centrifugation. The resulting cell pellet was suspended in 10 ml of Maintenance Medium and a cell count was performed. In an average experiment, 2 x 10s mononuclear cells are seeded into each well of 96-well plates in a total volume of 0.1 ml. Monocytes are 35 allowed to adhere for 2 hours, after which the supernatants are discarded and the attached cells are rinsed twice and then incubated in Maintenance Medium overnight at 37°C in a 5% CO2 environment.

The cultured monocytes can be activated with 10 ng/ml LPS (E. coli serotype 055:B5;

Sigma Chemicals, St. Louis, MO). Following a 2-hour incubation, the activation medium is removed, the cells are rinsed twice with 0.1 ml of Chase Medium (RPMI 1640, 1% FBS, 20 mM Hepes, 5 mM NaHCO3, pH 6.9), and then 0.1 ml of Chase Medium containing a test 5 agent is added and the plate is incubated for 30 minutes; each test agent concentration can be evaluated in triplicate wells. ATP then is introduced (from a 100 mM stock solution, pH 7) to achieve a final concentration of 2 mM and the plate is incubated at 37°C for an additional 3 hours. Media were harvested and clarified by centrifugation, and their IL-Ιβ content was determined by ELISA (R&amp;D Systems; Minneapolis, MN). 10 The compositions of the present invention may be formulated in a conventional manner using one or more pharmaceutically acceptable carriers. Thus, the active compounds of the invention may be formulated for oral, buccal, intranasal, parenteral (e.g., intravenous, intramuscular or subcutaneous), topical or rectal administration or in a form suitable for administration by inhalation or insufflation. 15 For oral administration, the pharmaceutical compositions may take the form of, for example, tablets or capsules prepared by conventional means with pharmaceutically acceptable excipients such as binding agents (e.g., pregelatinized maize starch, polyvinylpyrrolidone or hydroxypropyl methylcellulose); fillers (e.g., lactose, microcrystalline cellulose or calcium phosphate); lubricants (e.g., magnesium stearate, talc or silica); 20 disintegrants (e.g., potato starch or sodium starch glycolate); or wetting agents (e.g., sodium lauryl sulphate).
