Synthesis of new hybrid quinazoline compounds as antiproliferative agents for breast and colon cancer treatment

Purpose: To evaluate newly synthesized fuoryl quinazoline derivatives for antitumor efficacy. Methods: Fuoryl quinazoline derivatives were synthesized and the structures of the synthesized compounds were characterized using standard techniques. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) technique was used to assess the anti-proliferative properties of the synthesized derivatives in vitro. Results: All quinazoline compounds displayed cytotoxic activity against breast and colon cancer cell lines to varying degrees. Compound IXa with acetohydrazide moiety was the most effective on MCF7 and HCT116 cell lines, with half-maximal inhibitory concentration (IC50) values of 16.70 and 12.54 mu M, respectively. Conclusion: N'-benzylidene-2((2-(furan-2-yl) quinazolin-4-yl) oxy) acetohydrazide IXa showed the strongest anti-proliferative activity against MCF-7 and HCT116 human cancer cell lines.
