Design, synthesis, biological evaluation and molecular docking studies of new chalcone derivatives containing diaryl ether moiety as potential anticancer agents and tubulin polymerization inhibitors

A novel series of chalcone derivatives containing diaryl ether moiety (5a-5p) were designed, synthesized and evaluated their anti-tubulin polymerization activities and anticancer activities. Among them, compound 5b with 4-methoxy substitution on right aromatic ring was found to be most active on MCF-7, HepG2 and HCT116 cancer cell lines, with IC50 values of 3.44 ± 0.19, 4.64 ± 0.23, and 6.31 ± 0.27 μM, respectively. In vitro tubulin...
