    • The present invention relates to compounds of formula (I), wherein R is C1-6alkyl, C2-6alkenyl, C2-6alkynyl, C3-7cycloalkyl, C3-7cycloalyklC1-4alkyl, which groups are optionally substituted by hydroxy, C1-4alkoxy or NR R , where R and R each independently represent hydrogen or C1-4alkyl; or R is C1-4alkyl substituted by Ar, and optionally further substituted by one or both of R and R ; R , R and R represent a variety of substituents; R and R are each hydrogen, halogen, C1-6alkyl, CH2OR , oxo, CO2R or CONR R where R represents hydrogen, C1-6alkyl or phenyl; X is -CH2, or -CH2CH2-; Y is -CH=, -CH2-, -CH2CH= or -CH2CH2-, with the proviso that the sum total of carbon atoms in X+Y is 2 or 3; and when Y is -CH= or -CH2CH=, the broken line is a double bond; or a pharmaceutically acceptable salt thereof. The compounds are of particular use in the treatment or prevention of pain, inflammation, migraine, emesis and postherpetic neuralgia.
    • 本发明涉及式(I)化合物,其中R为C 1-6烷基,C 2-6烯基,C 2-6炔基,C 3-7环烷基,C 3-7环烷基C 1-4烷基,该基团任选被羟基,C 1-4烷氧基或NR 其中R a和R b各自独立地表示氢或C 1-4烷基; 或R为被Ar取代的C 1-4烷基,且任选进一步被R 4和R 5中的一个或两个取代; R 1,R 2和R 3代表各种取代基; R 9和R 10各自为氢,卤素,C 1-6烷基,CH 2 OH,氧代,CO 2 R a或CONR a R b,其中R e表示氢,C 1-6烷基 或苯基; X是-CH 2或-CH 2 CH 2 - ; Y是-CH =,-CH 2 - , - CH 2 CH =或-CH 2 CH 2 - ,条件是X + Y中的碳原子总数为2或3; 当Y为-CH =或-CH 2 CH =时,虚线为双键; 或其药学上可接受的盐。 该化合物特别用于治疗或预防疼痛,炎症,偏头痛,呕吐和带状疱疹后神经痛。
