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.
取代杂环芳香化合物,特别是式(I)的取代双环杂环芳香化合物,其中X为N或CH;A表示融合的含1至5个异原子的5、6或7元杂环,这些异原子可以相同或不同,并从N、O或S(O)m中选择,其中m如上所定义,杂环总共包含1、2或3个双键,包括与其融合的
吡啶或
嘧啶环中的键,但前提是杂环不是
嘌呤的一部分,并且融合的杂环不包含两个相邻的O或S(O)m原子。U表示5至10个成员的单环或双环环系,其中一个或多个碳原子可以选择性地由N、O和S(O)m中独立选择的异原子替换,其中m为0、1或2,并且该环系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。描述了这些化合物及其制备方法,包括这些化合物的制药组合物和它们在医药上的用途,例如用于癌症和牛皮癣的治疗。
