Three novel series of dihydrotriazine derivatives bearing 1,3-diaryl pyrazole moieties were designed, synthesized and evaluated in terms of their antibacterial and antifungal activities. Most of the synthesized compounds showed potent inhibition of several Gram-positive bacterial strains (including multidrug-resistant clinical isolates) and Gram-negative bacterial strains with minimum inhibitory concentration
设计,合成和评估了三个带有1,3-二芳基吡唑部分的二氢三嗪衍生物系列,并对其抗菌和抗真菌活性进行了评估。大多数合成的化合物均显示出对几种革兰氏阳性细菌菌株(包括耐多药临床分离株)和革兰氏阴性细菌菌株的有效抑制作用,其最低抑菌浓度值在1-64 µg / mL的范围内。化合物4b和4c对革兰氏阳性菌(金黄色葡萄球菌4220,MRSA 3167,QRSA 3519)和革兰氏阴性菌(大肠杆菌1924)表现出最强的抑制活性,最小抑菌浓度值为1或2 µg /毫升 与以前的研究相比,这些化合物表现出广谱的抑制活性。化合物4a,4b,在L02细胞中评估4c和11n。体外酶研究表明,化合物4c通过抑制DHFR发挥其抗菌活性。
