The invention relates to quinazoline derivatives of the formula:
[wherein:
Y1 represents —O—, —S—, —CH2—, —SO—, —SO2—, —NR5CO—, —CONR6—, —SO2NR7—, —NR8SO2— or —NR9— (wherein R5, R6, R8 and R9 each independently represents hydrogen, alkyl or alkoxyalkyl);
R1 represents hydrogen, hydroxy, halogeno, nitro, trifluoromethyl, cyano, alkyl, alkoxy, alkylthio, amino or alkylamino.
R2 represents hydrogen, hydroxy, halogeno, alkyl, alkoxy, trifluoromethyl, cyano, amino or nitro;
m is an integer from 1 to 5;
R3 represents hydroxy, halogeno, alkyl, alkoxy, alkanoyloxy, trifluoromethyl, cyano, amino or nitro;
R4 represents a group which is or which contains an optionally substituted pyridone, phenyl or aromatic heterocyclic group] and salts thereof; processes for their preparation and 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.
该发明涉及以下结构的喹唑啉衍生物:[其中:Y1代表—O—、—S—、—CH2—、—SO—、—SO2—、—NR5CO—、—CONR6—、—SO2NR7—、—NR8SO2—或—NR9—(其中R5、R6、R8和R9分别独立代表氢、烷基或烷氧基烷基);R1代表氢、羟基、卤素、硝基、三氟甲基、氰基、烷基、烷氧基、烷硫基、氨基或烷基氨基。R2代表氢、羟基、卤素、烷基、烷氧基、三氟甲基、氰基、氨基或硝基;m为1到5的整数;R3代表羟基、卤素、烷基、烷氧基、烷酰氧基、三氟甲基、氰基、氨基或硝基;R4代表一个或含有一个可选择取代的吡啶酮、苯基或芳香杂环基团的基团]及其盐;其制备方法以及含有I式化合物或其药学上可接受的盐作为活性成分的药物组合物。I式化合物及其药学上可接受的盐抑制VEGF的作用,这在治疗包括癌症和类风湿关节炎在内的多种疾病状态中具有价值。
