The targeted compounds were prepared using both (9H-fluoren-9-ylidene)hydrazine (1) and 10H-phenothiazine (2) as starting materials. The treatment of 1 or 2 with different isocyanates afforded the title compounds 7a–d, 8a, and 8b in excellent yield. All compounds were characterized and ascertained by infrared, nuclear magnetic resonance, and elemental analyses as well as single-crystal X-ray diffraction
使用(9 H-芴-9-亚基)肼( 1 )和10 H-吩噻嗪( 2 )作为起始原料制备目标化合物。用不同的异氰酸酯处理1或2,以优异的收率得到标题化合物7a-d 、 8a和8b 。所有化合物均通过红外、核磁共振、元素分析以及单晶 X 射线衍射进行了表征和确定。体外测试了所有化合物的抗菌效果,化合物7a 、 7b 、 8a和8b对枯草芽孢杆菌、金黄色葡萄球菌、铜绿假单胞菌、肺炎克雷伯菌和白色念珠菌均具有显着的抑制活性。此外,化合物7b和8b对所有细菌病原体的生物膜机制活性均具有强烈抑制作用,抑制率超过55%。分子对接模拟结果表明,化合物7a 、 7b 、 8a和8b表现出良好的结合能,并与甾醇 14-去甲基酶、二氢叶酸合酶、促旋酶 B、LasR(铜绿假单胞菌主要转录激活因子)的活性位点有效相互作用。 ) 和碳青霉烯酶分别用于白色念珠菌、金黄色葡萄球菌、枯草芽孢杆菌、肺炎克雷伯菌和铜绿假单胞菌。
