The invention relates to the use of compounds of formula (I) and isomers, salts, solvates, chemically protected forms, and prodrugs thereof, in the preparation of a medicament for inhibiting the activity of DNA-PK, wherein R
1
and R
2
are independently hydrogen, an optionally substituted C
1-7
alkyl group, C
3-20
heterocyclyl group, or C
5-20
aryl group, or may together form, along with the nitrogen atom to which they are attached, an optionally substituted heterocyclic ring having from 4 to 8 ring atoms; X and Y are selected from CR
4
and O, O and CR′
4
and NR″
4
and N, where the unsaturation is in the appropriate place in the ring, and where one of R
3
and R
4
or R′
4
is an optionally substituted C
3-20
heteroaryl or C
5-20
aryl group, and the other of R
3
and R
4
or R′
4
is H, or R
3
and R
4
or R″
4
together are -A-B—, which collectively represent a fused optionally substituted aromatic ring. The compounds also selectively inhibit the activity of DNA-PK compared to PI 3-kinase and/or ATM.
本发明涉及使用式(I)的化合物及其异构体、盐、溶剂合物、化学保护形式和前药,在制备抑制DNA-PK活性的药物方面有用。其中,R1和R2独立地表示氢、可选取代的C1-7烷基、C3-20杂环基或C5-20芳基,或者与它们连接的氮原子一起形成可选取代的含有4到8个环原子的杂环环;X和Y选自CR4和O,O和CR'4以及NR"4和N,其中不饱和度在环中适当位置,其中R3和R4或R'4中的一个为可选取代的C3-20杂芳基或C5-20芳基,而另一个为H,或者R3和R4或R"4在一起为-A-B-,代表一种融合的可选取代芳香环。这些化合物与PI 3-激酶和/或ATM相比,具有选择性地抑制DNA-PK的活性。
