There are described compounds of formula I ##STR1## wherein R.sub.1 and R.sub.2 are as defined in the description, Q is heterocyclyl boned via a ring nitrogen atom and having the formula IA ##STR2## wherein R.sub.3 and R.sub.4 and m and n are as defined in the description, the ring marked A is a heterocyclyl having 5 to 9 ring atoms and having at least one saturated bond, it being possible for a further ring hetero atom selected from O and S to be present in addition to the bonding nitrogen atom, the ring system marked B is a free or benzo-, thieno-, furo-, pyrrolo- or dihydropyrrolo-fused carbocyclic ring having from 5 to 9 carbon atoms that is fused to the ring A and may be unsaturated, partially saturated or fully saturated, and the bond marked by a parallel dotted line between the ring systems marked A and B is either a single bond or a double bond, and a salt thereof where at least one salt-forming group is present. The compounds are inhibitors of protein kinases and have, for example, antitumour activity.
描述了式I的化合物##STR1##其中R.sub.1和R.sub.2如描述中所定义,Q是通过一个环氮原子连接的杂环基,具有式IA的结构##STR2##其中R.sub.3和R.sub.4和m和n如描述中所定义,标记为A的环是具有5到9个环原子的杂环基,并且至少有一个饱和键,除了连接氮原子外,还可以存在另外选择的一个氧或硫的环杂原子,标记为B的环系统是与环A融合的自由或苯并、噻吩、呋喃、吡咯或二氢吡咯融合的碳环,含有5到9个碳原子,可以是不饱和、部分饱和或完全饱和的,并且标记为平行虚线的环A和B之间的键要么是单键要么是双键,以及其盐,其中至少存在一个形成盐的基团。这些化合物是蛋白激酶的抑制剂,具有例如抗肿瘤活性。
