PDK1 is an important regulator of the PI3K/Akt pathway, which has been found frequently activated in a large number of human cancers. Herein we described the preparation of novel substituted 3-anilino-quinolin-2(1H)-ones as PDK1 inhibitors. The synthesis is based around a Buchwald–Hartwig cross-coupling of various 3-bromo-6-substituted-quinolin-2(1H)-ones with three different functionalised anilines. The modular nature of the designed synthesis allowed access to a series of novel inhibitors through derivatisation of a late-stage intermediate. All compounds were screened against isolated PDK1 enzyme, with modest inhibition observed.
