A series of 4-anilinoquinazoline derivatives were designed and synthesized as novel c-myc promoter G-quadruplex binding ligands. Subsequent biophysical and biochemical evaluation demonstrated that the introduction of aniline group at 4-position of quinazoline ring and two side chains with terminal amino group improved their binding affinity and stabilizing ability to G-quadruplex DNA. RT-PCR assay and Western blot showed that compound 7a could down-regulate transcription and expression of c-myc gene in Hela cells, which was consistent with the behavior of an effective G-quadruplex ligand targeting c-myc oncogene. More importantly, RTCA and colony formation assays indicated that 7a obviously inhibited Hela cells proliferation, without influence on normal primary cultured mouse mesangial cells. Flow cytometric assays suggested that 7a induced Hela cells to arrest in G0/G1 phase both in a time-dependent and dose-dependent manner.
