To expand an efficient strategy for the conversion of antibacterial activity of fluoroquinolones into an antitumor activity, utilizing pharmacophore bioelectronics isosteric and its flattening and skeleton migration medicinal molecule construction method, a series of fluoroquinolone-3-N-amide compounds were synthesized by using amide group as the bioisostere of the fluoroquinolone C-3 carboxyl group and fluoroquinolone skeleton as a functional modification group, and their structures are confirmed by elemental analysis and spectral data. The results of in vitro antitumor activity showed that the anti-proliferative activity of the target compounds against the two experimental tumor cells (Hep-3B、Capan-1) was significantly stronger than that of the raw material ciprofloxacin, suggesting that replacing the C-3 carboxyl group with an amide group is beneficial to improve the antitumor activity of the quinolones, which provides a new structural modification pathway for transforming antibacterial activity of fluoroquinolone to antitumor activity.
