Abstract: The application concerns a compound of formula I: wherein one of P and Q is O, and the other of P and Q is CH, where there is a double bond between whichever of Q and P is CH and the carbon atom bearing the R3 group; Y is either O or S; 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 an optionally substituted heterocyclic ring having from 4 to 8 ring atoms; R3 is a phenyl or pyridyl group, attached by a first bridge group selected from —S—, —S(?O)—, —S(?O)2—, —O—, —NRN— and CRC1RC2— to an optionally substituted C5-20 carboaryl group, the phenyl or pyridyl group and optionally substituted C5-20 carboaryl group being optionally further linked by a second bridge group, so as to form an optionally substituted C5-7 ring, the phenyl or pyridyl group being further optionally substituted.

Abstract: 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.
