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)的化合物及其同分异构体、盐、溶剂合物、化学保护形式和前药,在制备抑制DNA-PK活性的药物方面使用,其中R1和R2独立地为氢、C1-7烷基、C3-20杂环基或C5-20芳基,可选地被取代,或者与它们所连接的氮原子一起形成一个具有4到8个环原子的可选取代杂环环;X和Y从CR4和O、O和CR′4和NR″4和N中选择,其中不饱和度在合适的环中,其中R3和R4或R′4中的一个是可选的C3-20杂芳基或C5-20芳基,而另一个是氢,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芳香环。这些化合物相对于PI 3-激酶和/或ATM也具有选择性抑制DNA-PK活性的作用。
