Substituted heteroaromatic compounds, and in particular substituted bicyclic heteroaromatic compounds of formula (I), wherein X is N or CH; A represents a fused 5, 6 or 7-membered heterocyclic ring containing 1 to 5 heteroatoms which may be the same or different and which are selected from N, O or S(O)m, wherein m is as defined above, the heterocyclic ring containing a total of 1, 2 or 3 double bonds inclusive of the bond in the pyridine or pyrimidine ring to which it is fused, with the provisos that the heterocyclic ring does not form part of a purine and that the fused heterocyclic ring does not contain two adjacent O or S(O)m atoms. U represents a 5 to 10-membered mono or bicyclic ring system in which one or more of the carbon atoms is optionally replaced by a heteroatom independently selected from N, O and S(O)m, wherein m is 0,1 or 2 and wherein the ring system is substituted by at least one independently selected R6 group and is optionally substituted by at least one independently selected R4 group, with the proviso that U does not represent phenyl; are protein tyrosine kinase inhibitors. The compounds are described as are methods for their preparation, pharmaceutical compositions including such compounds and their use in medicine, for example in the treatment of cancer and psoriasis.
取代的杂环芳香化合物,特别是公式(I)中的取代双环杂环芳香化合物,其中X是N或CH;A代表融合的5、6或7个成员的杂环环,其中包含1到5个异原子,可以相同或不同,选择自N、O或S(O)m,其中m如上所定义,杂环环包含总共1、2或3个双键,包括与其融合的吡啶或嘧啶环中的键,但前提是杂环环不是嘌呤的一部分,并且融合的杂环环不包含两个相邻的O或S(O)m原子。U代表一个5到10个成员的单环或双环环系统,其中一个或多个碳原子可以被独立选择自N、O和S(O)m的杂原子替换,其中m为0、1或2,并且该环系统被至少一个独立选择的R6基团取代,并且可以被至少一个独立选择的R4基团取代,但前提是U不代表苯基;这些化合物是蛋白酪氨酸激酶抑制剂。描述了这些化合物的制备方法,包括这些化合物的制药组合物以及它们在医学上的使用,例如在癌症和牛皮癣的治疗中。
