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. 查看全文查看/发表评论下载PDF阅读器 相关附件：附件1版权转让声明书 -->
