CA 2227814

This invention provides a compound of formula (I) and its pharmaceutically acceptable salts, wherein R is halo C1-C8 alkyl, halo C2-C8 alkenyl, halo C2- C8 alkynyl or halo C1-C8 alkyl substituted by hydroxy or C1-C8 alkoxy; R1 is hydrogen, halo or C1-C6 alkoxy; or R and R1, together with the two carbon atoms shared between the benzene ring and the R and R1, complete a fused C4-C6 cycloalkyl wherein one carbon atom is optionally replaced by oxygen and wherein one or two of the carbon atoms are optionally substituted by up to five substituents selected from halo, C1-C6 alkyl and halo C1-C6 alkyl; X is C1-C6 alkoxy, halo C1-C6 alkoxy, phenoxy or halo; and Ar is phenyl optionally substituted by halo. These compounds are of use in treating a gastrointestinal disorder, a central nervous system (CNS) disorder, an inflammatory disease, emesis, urinary incontinence, pain, migraine, sunburn, diseases, disorders and adverse conditions caused by Helicobacter pylori, or angiogenesis especially CNS disorders in a mammalian subject, especially humans.

L'invention concerne un composé de la formule (I) ainsi que ses sels pharmaceutiquement acceptables, dans laquelle R représente haloalkyle C¿1?-C¿8?, haloalcényle C¿2?-C¿8?, haloalkynyle C¿2?-C¿8? ou haloalkyle C¿1?-C¿8? substitué par hydroxy ou alcoxy C¿1?-C¿8?; R?1¿ représente hydrogène, halo ou alcoxy C¿1?-C¿6?; ou R et R?1¿, avec les deux atomes de carbone partagés entre le noyau de benzène et les R et R?1¿, complètent un cycloalkyle C¿4?-C¿6? fusionné, dans lequel un atome de carbone est facultativement remplacé par de l'oxygène et dans lequel un ou deux des atomes de carbone sont facultativement substitués par un maximum de cinq substituants choisis entre halo, alkyle C¿1?-C¿6? et haloalkyle C¿1?-C¿6?; X représente alcoxy C¿1?-C¿6?, haloalcoxy C¿1?-C¿6?, phénoxy ou halo; et Ar représente phényle facultativement substitué par halo. Ces composés sont utiles dans le traitement de troubles gastrointestinaux, de troubles du système nerveux central, de maladies inflammatoires, des vomissements, de l'incontinence urinaire, de la douleur, de la migraine, de l'érythème solaire, de diverses maladies, de dysfonctionnements et d'états pathologiques provoqués par l'Helicobacter pylori, ou de l'angiogénèse, notamment de troubles du système nerveux central chez un sujet mammifère, notamment chez l'homme.
