ORGANOSILICON COMPOUNDS AND THEIR USE AS THE MODULATORS OF THE TRPV1 RECEPTOR

A compound having the Formula (1): wherein: X1, X2, X3 and X4 independently represent CH or N; R1, R2 and R3 independently represent C1-6 alkyl, C3-8 cycloalkyl or C3-8 cycloalky IC1-6alkyl, each of which groups may be optionally substituted with one or more substituents independently selected from halogen and haloC1-6 alkyl; R4, R5, R6, R7, R8 and R9 independently represent H, C1-6 alkyl, C3-8 cycloalkyl or -QI-OR14, or R4 and R9 may join to form a bridging C1-6 alkylene chain; R10 represents aryl or heteroaryl, each of which may be optionally substituted by one or more substituents, independently selected from halogen, C1-6 alkyl, haloC1-6 alkyl, hydroxyC1-6alkyl, haloC1-6 alkoxy, cyano, -Q2-CO2R12, -Q2-COR12, -Q2-CONR12R13, -Q2-OR12, -Q2-NR12Rn, -Q2-NR12SO2R13, -Q2- NR12COR13, -Q2-SO2NR12R13, -Q2-S(O)mR12, -Y-aryl, -Y-heteroaryl, -Y-C3-8 cycloalkyl and -Y-heterocyclyl; Q1 and Q2 independently represent a covalent bond, C1-6 alkylene, or 1-6 alkylene substituted with hydroxy; R12 and R13 independently represent a H atom, or a C1-6 alkyl or C3-8 cycloalkyl group, in which each group may be optionally substituted with one or more C1-6 alkoxy; or when R12 and R13 are attached to the same nitrogen atom they may join to form a nitrogen containing heterocyclyl ring, which may be optionally substituted with one or more substituents independently selected from C1-6 alkyl and C1-6 alkoxy; R14 represents a H atom, or a C1-6 alkyl or C3-8 cycloalkyl group, in which each group may be optionally substituted with one or more C1-6 alkoxy; Y represents a covalent bond, C1-6 alkylene, or -O-. m represents 0, 1 or 2; R11, which is optionally present and may be attached to any available carbon atom X1 to X4 instead of H, represents halogen, haloC1-6alkyl, C1-6alkoxy, haloC1-6alkoxy, cyano or C1-6 alkyl which may be optionally substituted with one or more substituents independently selected from halogen, haloC1-6 alkyl and OR16; q represents 0, 1 or 2; W represents -(CH2)n-, which may be optionally substituted with one or more substituents independently selected from C1-6 alkyl, C3-8 cycloalkyl and -Q3-OR15; n represents 1 or 2; Q3 represents a covalent bond or C1-6 alkylene; R15 represents H, C1-6 alkyl, or C3-8 cycloalkyl; R16 is as defined for R14; or a pharmaceutically acceptable salt or ester thereof. Uses of the compounds as modulators of the TrpVl receptor are also disclosed. L'invention porte sur un composé représenté par la formule (1) : dans laquelle : X1, X2, X3
