A compound of formula I: and isomers, salts, solvates, chemically protected forms, and prodrugs thereof, wherein: Rand Rare independently selected from hydrogen, an optionally substituted Calkyl group, Cheterocyclyl group, or Caryl 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; Q is &#x2014;NH&#x2014;C(&#x2550;O)&#x2014; or &#x2014;O&#x2014;; Y is an optionally substituted Calkylene group; X is selected from SRor NRR, wherein, R, or Rand Rare independently selected from hydrogen, optionally substituted Calkyl, Caryl, or Cheterocyclyl groups, or Rand Rmay together form, along with the nitrogen atom to which they are attached, an optionally substituted heterocyclic ring having from 4 to 8 ring atoms; if Q is &#x2014;O&#x2014;, X is additionally selected from &#x2014;C(&#x2550;O)&#x2014;NRR, wherein Rand Rare independently selected from hydrogen, optionally substituted Calkyl, Caryl, or Cheterocyclyl groups, or Rand Rmay together form, along with the nitrogen atom to which they are attached, an optionally substituted heterocyclic ring having from 4 to 8 ring atoms; and if Q is &#x2014;NH&#x2014;C(&#x2550;O)&#x2014;, &#x2014;Y&#x2014;X may additionally be selected from Calkyl.

DNA-PK inhibitors

Compounds of formula I: wherein A, B and D are respectively selected from the group consisting of:

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 Rand Rare independently hydrogen, an optionally substituted Calkyl group, Cheterocyclyl group, or Caryl 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 CRand O, O and CR'and NR&#x2033;and N, where the unsaturation is in the appropriate place in the ring, and where one of Rand Ror R&#x2032;is an optionally substituted Cheteroaryl or Caryl group, and the other of Rand Ror R&#x2032;is H, or Rand Ror R&#x2033;together are &#x2014;A&#x2014;B&#x2014;, 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.

The compounds also selectively inhibit the activity of DNA-PK compared to PI 3-kinase and/or ATM.

The present invention provides compounds of formula (I) and isomers, salts, solvates, chemically protected forms, and prodrugs thereof, wherein Rand Rare independently hydrogen, an option ally substituted Calkyl group, Cheterocyclyl group, or Caryl 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; and Ris an optionally substituted Cheterocyclyl or Caryl group, and their use as pharmaceuticals, particularly in treating diseases which are retroviral mediated or ameliorated by the inhibition of DNA-PK,
