Synthesis and biological activity of imidazo[4,5-c]quinoline derivatives as PI3K/mTOR inhibitors
A series of imidazo[4,5-c]quinoline derivatives(12a—12m) was synthesized with 2-amino-5-bromobenzoic acid and 4-nitrophenylacetonitrile as starting materials, 6-bromo-4-chloro-3-nitroquinoline as intermediate and Suzuki reaction and closure of the imidazolinone ring with triphosgene as key steps. The structures of the key intermediate and target compounds were confirmed by means of 1H NMR, 13C NMR and HRMS. These compounds show an interesting kinase profile as dual PI3K/mTOR tool compounds.
