potential antibacterial agents in the quinolones field, we have synthesized novel quinolone agents bearing N-[2-(thiophen-3-yl)ethyl] piperazinyl moiety in the 7-position of the quinolone ring. In vitro antibacterial evaluation of the target compounds showed that N-[2-(thiophen-3-yl)ethyl] group attached to piperazine ring served as promising C-7 substituent for piperazinyl quinolone antibacterials.

作为在喹诺酮类领域中不断寻找潜在抗菌剂的一部分,我们合成了在喹诺酮环的7位带有N- [2-(噻吩-3-基)乙基]哌嗪基部分的新型喹诺酮剂。对目标化合物的体外抗菌评估显示,与哌嗪环相连的N- [2-(噻吩-3-基)乙基]基团是哌嗪基喹诺酮类抗菌药物的有希望的C-7取代基。在这些衍生物中,含有N- [2-(噻吩-3-基)-2-羟基亚氨基乙基]或N- [2-(噻吩-3-基)-2-甲氧基亚氨基乙基]残基的环丙沙星类似物对所有化合物的抑制作用都很高。被测试的革兰氏阳性生物,包括耐甲氧西林的金黄色葡萄球菌,相对于参比药物诺氟沙星和环丙沙星而言相当或更好。
