Synthesis and anticancer activities of 5,6,7-trimethoxy-N-phenyl(ethyl)-4-aminoquinazoline derivatives
چکیده انگلیسی


• New 5,6,7-trimethoxy-N-phenyl(ethyl)-4-aminoquinazoline derivatives are synthesized.
• Many of the new compounds well inhibit EGF-induced ERK1/2 phosphorylation.
• Some of the new compounds show good antiproliferation activities against tumor cells.
• Mechanism study indicates that compound 6x can induce cell apoptosis in PC3 cells.

A series of 5,6,7-trimethoxy-N-phenyl(ethyl)-4-aminoquinazoline compounds was prepared by microwave irradiation and conventional heating methods. Compounds 6p, 6q, and 6x strongly inhibited extracellular regulated kinase1/2 (ERK1/2) phosphorylation induced by epidermal growth factor (EGF) at 1.28 μM in PC3 cells. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay showed that all compounds had certain anticancer activities, and the IC50 values of 6x were 6.2 ± 0.9, 3.2 ± 0.1, and 3.1 ± 0.1 μM against PC3, BGC823, and Bcap37 cells, respectively. Acridine orange/ethidium bromide staining, Hoechst 33258 staining, DNA ladder, and flow cytometry analyses revealed that 6x induced cell apoptosis in PC3 cells, with apoptosis ratios of 11.6% at 1 μM and 31.8% at 10 μM after 72 h.

A series of new 5,6,7-trimethoxy-N-phenyl(ethyl)-4-aminoquinazoline derivatives was prepared and found to possess good antiphosphorylation, antiproliferation, and apoptosis-inducing effects on PC3 cells.Figure optionsDownload as PowerPoint slide
