Abstract:
A compound as a vanilloid receptor antagonist is provided to obtain a high activity in preventing or treating pain, migraine, arthralgia, neuralgia, neural diseases, neural injury, skin diseases, irritable bowel syndrome, inflammatory diseases, cardiac diseases, etc. A compound as a vanilloid receptor antagonist is a compound represented by the following formula Ia or an isomer and/or pharmaceutically acceptable salt thereof. In formula Ia, X is CR11=CR12 or C=C, wherein each of R11 and R12 independently represents H, a halogen atom, C1-C5 alkyl or phenyl; each of R1 and R2 independently represents H, carboxyl, C1-C5 alkyl, halogen, nitro, C1-C5 alkoxy, halo(C1-C5)alkyl, C1-C5 alkylcarbonyl, C1-C5 alkylcarbonylamino, C1-C5 alkylsulfonylamino, phenylsulfonylamino, C1-C5 alkylthio, C1-C5 alkylsulfonyl or C1-C5 alkoxycarbonyl; R3 is H, C1-C5 alkyl, C1-C5 alkoxy or halo(C1-C5)alkyl; each of R4, R5, R6, R7 and R8 independently represents H, carboxyl, C1-C5 alkyl, nitro, C2-C5 alkenyl, C1-C5 alkoxy, C2-C5 alkynyl, halo(C1-C5)alkyl, C1-C5 alkylthio, C1-C5 alkylsulfonyl, C1-C5 alkylcarbonyl, C1-C5 alkoxycarbonyl, phenyl or halogen, wherein the phenyl is non-substituted or substituted with at least one substituent selected from carboxyl, C1-C5 alkyl, halogen, nitro, C2-C5 alkenyl, C1-C5 alkoxy, halo(C1-C5)alkyl, C1-C5 alkylcarbonyl, C1-C5 alkylthio, C1-C5 alkylsulfonyl and C1-C5 alkoxycarbonyl; R9 is C1-C5 alkylsulfonyl or C2-C5 alkenylsulfonyl; and R10 is H, with the proviso that when R3 is not H, R11 and R13 cannot represent H at the same time.
