Compounds of formula (I) are ligands of the CRTH2 receptor, useful in the treatment of, for example, inflammatory respiratory disease: R1 is fluoro, chloro, CN or CF3; R2 is hydrogen, fluoro or chloro; X is -CH2-, or - S(O)n-; Ar1 is phenyl or 5- or 6-membered heteroaryl, wherein the phenyl or heteroaryl rings are optionally substituted with one substituent selected from fluoro, chloro, CN, -O(C1-C3alkyi) or C1-C3alkyl, the latter two groups being optionally substituted by one or more fluoro atoms; Y is -CR3R4-, -C(O)-, -O-, -S(O)2- or -NR3-; R3 and R4 independently represent hydrogen or C1-C3alkyl; Ar2 is phenyl or 5- or 6- membered heteroaryl, wherein the phenyl or heteroaryl rings are optionally substituted by one or more substituents independently selected from halogen, - CN, -S(O)nR5, -S(O)2NR6R7, -NR6S(O)2R5 -NR6R7, -NR6COR5, -CONR6R7, -COR5, -OR6, C1- C6alkyl or C3-C7cycloalkyl, the latter two groups being optionally substituted by one or more fluoro atoms; R5 is C1-C6alkyl or C3-C7cycloalkyl, optionally substituted by one or more fluoro atoms; R6 and R7 independently represent hydrogen, C1-C6alkyl or C3-C7cycloalkyl, the latter two groups being optionally substituted by one or more fluoro atoms; and n is O, 1 or 2.
化合物的结构式(I)是CRTH2受体的配体,在治疗例如炎症性呼吸道疾病方面很有用:R1是氟、氯、CN或CF3;R2是氢、氟或氯;X是-CH2-或-S(O)n-;Ar1是苯基或5-或6-成员杂环基,其中苯基或杂环基环可以选择性地用来自氟、氯、CN、-O(C1-C3烷基)或C1-C3烷基的一个取代基取代,后两个基可以选择性地用一个或多个氟原子取代;Y是-CR3R4-,-C(O)-,-O-,-S(O)2-或-NR3-;R3和R4独立地代表氢或C1-C3烷基;Ar2是苯基或5-或6-成员杂环基,其中苯基或杂环基环可以选择性地用一个或多个取代基独立地选自卤素、-CN、-S(O)nR5、-S(O)2NR6R7、-NR6S(O)2R5、-NR6R7、-NR6COR5、-CONR6R7、-COR5、-OR6、C1-C6烷基或C3-C7环烷基取代,后两个基可以选择性地用一个或多个氟原子取代;R5是C1-C6烷基或C3-C7环烷基,可以选择性地用一个或多个氟原子取代;R6和R7独立地代表氢、C1-C6烷基或C3-C7环烷基,后两个基可以选择性地用一个或多个氟原子取代;n是O、1或2。
