Description

NOVEL COMPOUNDS DESCRIPTION OF THE INVENTION The present invention relates to novel compounds, to processes for their preparation, to pharmaceutical compositions containing them and to their use in therapy. Chemokines play an important role in immune and inflammatory responses in various diseases and disorders, including asthma and allergic diseases, as well as autoimmune pathologies, such as rheumatoid arthritis and atherosclerosis. These small, secreted molecules are a growing superfamily of 8-14 kDa proteins characterized by a conserved configuration of four cysteines. The chemokine superfamily can be divided into two main groups that exhibit structural configurations, characteristics, the Cys-X-Cys (C-X-C) and Cys-Cys (C-C) families. These differ on the basis of a single amino acid insertion between the pair close to NH of the cysteine residues and a sequence similarity. The C-X-C chemokines include several chemoattractants and potent activators of neutrophils, such as interleukin-8 (? L-8) and the activating peptide of REF: 172599 neutrophils 2 (NAP-2). CC chemokines include potent chemoattractants of monocytes and lymphocytes but not neutrophils, such as the human monocyte chemotactic proteins 1-3 (MCP-1, MCP-2 and MCP-3), RANTES (Normal, Expressed and Secreted T Cells, Regulated with Activation), eotaxin and the inflammatory proteins of macrophages la and lß (MlP-la and MlP-lß). Studies have shown that the actions of chemokines are mediated by sub-families of receptors coupled to the G protein, among which are the designated receptors CCR1, CCR2, CCR2A, CCR2B, CCR3, CCR4, CCR5, CCR6, CCR7, CCR8, CCR9, CCR10, CXCR1, CXCR2, CXCR3 and CXCR4. These receptors represent good targets for drug development since agents that modulate these receptors would be useful in the treatment of disorders and diseases, such as those mentioned above. According to the present invention, therefore, a compound of the formula is provided where m is O, 1, 2, 3 or 4; each R1 independently represents halogen, cyano, hydroxyl, alkyl of 1 to 6 carbon atoms, haloalkyl of 1 to 6 carbon atoms, alkoxy of 1 to 6 carbon atoms or sulfonamido; X represents a bond, -CH2- or -0-, Y represents a bond, -CH2- or -0- and Z represents a bond -0-, -NH- or -CH2-, with the condition that only one of X, Y and Z can represent a link at any time and with the proviso that X and Y do not represent both simultaneously -0-; n is 0, 1 or 2; each R2 independently represents halogen, alkyl of 1 to 6 carbon atoms or haloalkyl of 1 to 6 carbon atoms; q is 0 or 1; t is O, 1, 2, 3, 4 or 5; each R3 independently represents halogen, cyano, nitro, hydroxyl, -C (0) H, -NR9R10, -CH2C (O) NR ^ R12, -CH2NHC (0) R13, -NHS02R14, -S02NR15R16, -CH2-R17, alkylcarbonyl from 1 to 6 carbon atoms, phenylcarbonyl, cycloalkyl of 3 to 6 carbon atoms or a group selected from alkyl of 1 to 6 carbon atoms, alkenyl of 2 to 6 carbon atoms, alkynyl of 2 to 6 carbon atoms, C 1-6 alkoxy, phenyl and a 5- to 10-membered, saturated or unsaturated heterocyclic ring system comprising at least one ring heteroatom selected from nitrogen, oxygen and sulfur, each group is optionally substituted by at least one substituent selected from halogen, cyano, hydroxyl, carboxyl, alkyl of 1 to 6 carbon atoms, alkoxy of 1 to 6 carbon atoms and alkoxycarbonyl of 1 to 6 carbon atoms; R4, R5, Rd, R7 and R8 each independently represent hydrogen, halogen, alkyl of 1 to 6 carbon atoms or haloalkyl of 1 to 6 carbon atoms; R9 and R10 each independently represent hydrogen or alkyl of 1 to 6 carbon atoms; R11 and R12 each independently represent hydrogen or alkyl of 1 to 6 carbon atoms or R11 and R12 together with the nitrogen atom to which they are attached form a heterocyclic, saturated 4- to 7-membered ring, which may be optionally substituted by at least one substituent selected from hydroxyl; R 13 and R 14 each independently represent hydrogen or alkyl of 1 to 6 carbon atoms; and R15 and R16 each independently represent hydrogen or alkyl of 1 to 6 carbon atoms or R15 and R16 together with the nitrogen atom to which they are attached form a heterocyclic, saturated 4- to 7-membered ring, which may be optionally substituted by at least one substituent selected from hydroxyl; R17 is a 5- to 7-membered saturated heterocyclic ring containing at least one nitrogen atom, the ring which may be optionally substituted by one or more oxo groups; or a pharmaceutically acceptable salt or solvate thereof.

Methods Culture of THP-1 cells Cells are thawed rapidly at 37 ° C frozen aliquots and resuspended in a 25 cm flask containing 5 ml of RPMI-1640 medium supplemented with Glutamax ™ and 10% thermally inactivated fetal bovine serum. without antibiotics (RPMI + 10% HIFCS). On day 3, the medium is discarded and replaced by a fresh medium. THP-1 cells are cultured in a normal manner in RPMI-1640 medium supplemented with 10% thermal inactivated fetal bovine serum and Glutamax ™ but without antibiotics. The optimal growth of the cells requires that they be evacuated every 3 days and that the minimum density of the subculture be 4 x 105 cells / ml.
Chemotaxis Assay The cells are removed from the flask and washed by centrifugation in RPMI + 10% HIFCS + Glutamax ™. The cells are then resuspended at 2 × 10 7 cells / ml in fresh medium (RPMI + 10% HIFCS + Glutamax ™) to which calcein-AM (5 μl of stock solution at 1 ml is added to give a final concentration of 5 × 10_dM). After gentle mixing, the cells are incubated at 37 ° C in a CO 2 incubator for 30 minutes. The cells are then diluted to 50 ml with the medium and washed twice by centrifugation at 400 x g. The labeled cells are then resuspended at a cell concentration of 1 x 10 7 cells / ml and incubated with an equal volume of MlP-la antagonist (final concentration of 10"10M to 10_6M) for 30 minutes at 37 ° C in a humidified CO 2 incubator Chemotaxis is performed using 96-well chemotaxis plates Neuroprobe ™ using 8 μm filters (no of cat 101-8) Thirty microliters of the chemoattractant supplemented with various concentrations of antagonists or vehicle is added to the bottom wells of the plate in triplicate.The filter is then carefully placed on top and, then, 25 μl of cells previously incubated with the corresponding concentration of antagonist or vehicle are added to the filter surface. The plate is then incubated for 2 hours at 37 ° C in a humidified C02 incubator. The cells that remain on the surface are then removed by adsorption and the whole silver is centrifuged at 2000 rpm for 10 minutes. The filter is then removed and the cells that have migrated to the lower wells are quantified by the fluorescence of the calcein-AM associated with the cells. Cell migration is then expressed in fluorescence units after subtraction of the reagent model and the values are standardized at% migration by comparing the fluorescence values with that of a known number of labeled cells. The effect of the antagonists is calculated as% inhibition when the number of emigrated cells is compared with the vehicle.
It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
