The invention relates to quinazoline derivatives of the formula: ##STR1## \x9bwherein: Y.sup.1 represents --O--, --S--, --CH.sub.2 --, --SO--, --SO.sub.2 --, --NR.sup.5 CO--, --CONR.sup.6 -, --SO.sub.2 NR.sup.7 -, --NR.sup.8 SO.sub.2 -- or --NR.sup.9 - (wherein R.sup.5, R.sup.6, R.sup.7, R.sup.8 and R.sup.9 each independently represents hydrogen, alkyl or alkoxyalkyl); R.sup.1 represents hydrogen, hydroxy, halogeno, nitro, trifluoromethyl, cyano, alkyl, alkoxy, alkylthio, amino or alkylamino. R.sup.2 represents hydrogen, hydroxy, halogeno, alkyl, alkoxy, trifluoromethyl, cyano, amino or nitro; m is an integer from 1 to 5; R.sup.3 represents hydroxy, halogeno, alkyl, alkoxy, alkanoyloxy, trifluoromethyl, cyano, amino or nitro; R.sup.4 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.
该发明涉及以下式的喹唑啉衍生物:##STR1## 其中:Y.sup.1代表--O--,--S--,--CH.sub.2--,--SO--,--SO.sub.2--,--NR.sup.5 CO--,--CONR.sup.6-,--SO.sub.2 NR.sup.7-,--NR.sup.8 SO.sub.2--或--NR.sup.9-(其中R.sup.5,R.sup.6,R.sup.7,R.sup.8和R.sup.9分别独立地代表氢,烷基或烷氧基烷基);R.sup.1代表氢,羟基,卤素,硝基,三氟甲基,氰基,烷基,烷氧基,烷基硫基,氨基或烷基氨基。R.sup.2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至5的整数;R.sup.3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;R.sup.4代表一个含有或含有可选择替代的吡啶酮,苯基或芳香杂环基的基团!及其盐;它们的制备方法和含有式I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。式I化合物及其药学上可接受的盐抑制VEGF的作用,这是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特性。
