The invention relates to quinazoline derivatives of formula (I), wherein m is an integer from 1 to 3; R
1
represents halogeno or C
1-3
alkyl; X
1
represents —O—; R
2
is selected from one of the following three groups: 1) C
1-5
alkylR
3
(wherein R
3
is piperidinyl-4-yl which may bear one or two substituents selected from hydroxy, halogeno, C
1-4
alkyl, C
1-4
hydroxyalkyl and C
1-4
alkoxy; 2) C
2-5
alkenylR
3
(wherein R
3
is as defined hereinbefore); 3) C
2-5
alkynylR
3
(wherein R
3
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)的喹唑啉衍生物,其中m是1到3的整数; R1代表卤素或C1-3烷基; X1代表—O—; R2从以下三个组中选择一个:1)C1-5烷基R3(其中R3是哌啶基-4-基,可以带有一个或两个从羟基,卤素,C1-4烷基,C1-4羟基烷基和C1-4烷氧基中选择的取代基; 2)C2-5烯基R3(其中R3如上所定义); 3)C2-5炔基R3(其中R3如上所定义); 其中任何烷基,烯基或炔基可以带有一个或多个从羟基,卤素和氨中选择的取代基;以及它们的盐;制备它们的过程,包含式(I)的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)的化合物和其药学上可接受的盐抑制VEGF的作用,在治疗包括癌症和类风湿性关节炎在内的多种疾病状态中具有价值的性质。
