8-Substituted 2-morpholin-4-yl-quinolin-4-ones and 9-substituted 2-morpholin-4-yl-pyrido[1,2-a]pyrimidin-4-ones with selected aryl and heteroaryl groups as the substituent have been synthesised as potential inhibitors of DNA-dependent protein kinase. A multiple-parallel approach, employing Suzuki cross-coupling methodology, was utilised in the preparation of 8-substituted 2-morpholin-4-yl-quino...
