Substituted heteroaromatic compounds of formula (I) and in particular substituted quinolines and quinazolines, 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, or a salt or solvate thereof; wherein X is N or CH; Y is a group W(CH2), (CH2)W, or W, in which W is O, S(O)m wherein m is 0, 1 or 2, or NRa wherein Ra is hydrogen or a C1-8 alkyl group; R1 represents a phenyl group or a 5- or 6-membered heterocyclic ring containing 1 to 4 heteroatoms selected from N, O or S(O)m, wherein m is as defined above, with the provisos that the ring does not contain two adjacent O or S(O)m atoms and that where the ring contains only N as heteroatom(s) the ring is C-linked to the quinazoline or quinoline ring, R1 being optionally substituted by one or more R3;groups; P=0 to 3; U, R2, R3 are as defined in the application.
代替的杂环芳烃化合物的化学式(I),特别是代替的喹啉和喹唑啉,是蛋白酪氨酸激酶抑制剂。这些化合物的制备方法被描述,包括含有这些化合物的药物组合物以及它们在医学上的用途,例如用于癌症和牛皮癣的治疗,或其盐或溶剂化合物;其中X为N或CH;Y为W(CH2)、(CH2)W或W的基团,其中W为O、S(O)m,其中m为0、1或2,或NRa,其中Ra为氢或C1-8烷基基团;R1代表苯基或含有1至4个来自N、O或S(O)m的杂原子的5-或6元杂环环,其中m如上定义,但环不含有两个相邻的O或S(O)m原子,并且当环仅含有N作为杂原子时,环与喹唑啉或喹啉环C键连接,R1可选择地被一个或多个R3基团取代;P = 0到3;U、R2、R3如申请中所定义。
