A compound having structure (I) wherein (a) n is from 1 to about 3; (b) X is selected from the group consisting of O, S, SO, or SO2; (c) Y is independently hydrogen or straight, branched or cyclic alkyl having from 1 to about 4 carbon atoms, or the Y's are bonded together to form an alkanyl ring having from 3 to 7 atoms other than hydrogen; (d) Z is hydrogen or straight, branched or cyclic alkyl; Z having from 3 to about 10 atoms other than hydrogen; (e) R1 is hydrogen or straight, branched or cyclic alkyl, halo, carboxyl, carboxamido, alkoxycarbonyl or alkylcarbonyl; (f) T is O or S; (g) U is O, S, N or N-R2; (h) W is CR3R4, C=O, C=S, C=NR5, C-O-R6, C-S-R6, C-NH2, C-NH-R7, or C-NR6R7; (i) V is (CH2)n, O, S, or N-R2; (j) R2 is hydrogen, alkyl, hydroxy, alkoxy, alkoxycarbonyl, or alkylcarbonyl; (k) R3 and R4 are independently selected from the group consisting of hydrogen, alkyl, halo, hydroxy, alkoxy, mercapto, alkylthio, or cyano; (l) R5 is hydrogen, alkyl, hydroxy or alkoxy; (j) R6 is hydrogen or alkyl; and (k) R7 is hydrogen, alkyl or C(=NH)N(R6)2. Pharmaceutical compositions comprising such compounds, and methods of treating inflammation or pain using such compounds.

L'invention concerne un composé ayant la structure (I) dans laquelle (a) n vaut de 1 à environ 3; (b) X est sélectionné dans le groupe constitué par O, S, SO ou SO¿2?; (c) Y représente indépendamment hydrogène ou alkyle droit, ramifié ou cyclique possédant de 1 à environ 4 atomes de carbone; ou bien les Y sont liés afin de former un noyau alcanyle possédant de 3 à 7 atomes autres que l'hydrogène; (d) Z représente hydrogène ou alkyle droit, ramifié ou cyclique; Z possédant de 3 à environ 10 atomes autres que l'hydrogène; (e) R¿1? représente hydrogène, ou alkyle droit, ramifié ou cyclique, halo, carboxyle, carboxamido, alcoxycarbonyle ou alkylcarbonyle; (f) T représente O ou S; (g) U représente O, S, N ou N-R¿2?; (h) W représente CR¿3?R¿4?, C=O, C=S, C=NR¿5?, C-O-R¿6?, C-S-R¿6?, C-NH¿2?, C-NH-R¿7? ou C-NR¿6?R¿7?; (i) V représente (CH¿2?)¿n?, O, S ou N-R¿2?; (j) R¿2? représente hydrogène, alkyle, hydroxy, alcoxy, alcoxycarbonyl ou alkylcarbonyle; (k) R¿3? et R¿4? sont indépendamment sélectionnés dans le groupe constitué par hydrogène, alkyle, halo, hydroxy, alcoxy, mercapto, alkythio ou cyano; (l) R¿5? représente hydrogène, alkyle, hydroxy ou alcoxy; (j) R¿6? représente hydrogène ou alkyle; et (k) R¿7? représente hydrogène, alkyle ou C(=NH)N(R¿6?)¿2?. L'invention concerne également des compositions pharmaceutiques comprenant ces composés ainsi que des procédés de traitement de l'inflammation ou de la douleur au moyen de ces composés.
