The invention relates to quinazoline derivatives of formula (I), wherein m is an integer from 1 to 3; R1 represents halogeno or C¿1-3?alkyl; X?1¿ represents -O-; R2 is selected from one of the following three groups: 1) C¿1-5?alkylR?3¿ (wherein R3 is piperidin-4-yl which may bear one or two substituents selected from hydroxy, halogeno, C¿1-4?alkyl, C1-4hydroxyalkyl and C1-4alkoxy; 2) C2-5alkenylR?3¿ (wherein R3 is as defined hereinbefore); 3) C¿2-5?alkynylR?3¿ (wherein R3 is as defined hereinbefore); and wherein any alkyl, alkenyl or alkynyl group may bear one or more substituents selected from hydroxy, halogeno and amino; and salts thereof; processes for their preparation, pharmaceutical compositions containing a compound of formula (I) or a pharmaceutically acceptable salt thereof as active ingredient. The compounds of formula (I) and the pharmaceutically acceptable salts thereof inhibit the effects of VEGF, a property of value in the treatment of a number of disease states including cancer and rheumatoid arthritis.
本发明涉及式(I)的喹噁啉衍
生物,其中m为1至3的整数;R1代表卤素或C1-3烷基;X1代表-O-;R2从以下三组中选择一组:1)C1-5烷基R3(其中R3是
哌啶-4-基,可以带有一个或两个取自羟基、卤素、C1-4烷基、C1-4羟基烷基和C1-4烷氧基的取代基);2)C2-5烯基R3(其中R3如前所定义);3)C2-5炔基R3(其中R3如前所定义);其中任何烷基、烯基或炔基可以带有一个或多个取自羟基、卤素和
氨基的取代基;以及它们的盐;制备它们的过程,含有式(I)化合物或其药学上可接受的盐作为活性成分的制药组合物。式(I)化合物及其药学上可接受的盐抑制V
EGF的作用,这是治疗包括癌症和类风湿性关节炎在内的多种疾病状态的有价值的特性。
