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 R1 and R2 are independently hydrogen, an optionally substituted C1-7 alkyl group, C3-20 heterocyclyl group, or C5-20 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 CR4 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 R3 and R4 or R′4 is an optionally substituted C3-20 heteroaryl or C5-20 aryl group, and the other of R3 and R4 or R′4 is H, or R3 and R4 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、溶剂和化学保护形式以及其前药,在制备用于抑制DNA-PK活性的药物中使用,其中R1和R2分别是氢、可选取代的C1-7烷基、C3-20杂环基或C5-20芳基,或者与它们附着的氮原子一起形成可选取代的含有4-8个环原子的杂环环;X和Y从CR4和O、O和CR′4和NR″4和N中选择,其中不饱和性在环中适当的位置,其中R3和R4或R′4中的一个是可选取代的C3-20杂芳基或C5-20芳基,另一个是氢,或者R3和R4或R″4一起是-A-B-,其共同代表一个融合的可选取代的芳香环。这些化合物相对于PI 3-激酶和/或ATM选择性地抑制DNA-PK的活性。
