Some novel (phenyl-diazenyl)phenols (4a-m) were designed and synthesized to be evaluated for their antibacterial activity. Starting from an active previously-synthesized azobenzene chosen as lead compound, we introduced some modifications and optimization of the structure, in order to improve solubility and drug conveyance. Structures of all newly-synthesized compounds were confirmed by ¹H nuclear
设计并合成了一些新颖的(苯基-二氮烯基)苯酚(4a-m),以评估其抗菌活性。从活性的事先合成的偶氮苯(作为先导化合物)开始,我们引入了一些修饰和结构优化,以提高溶解度和药物传递性。通过1 H核磁共振(NMR),质谱法和UV-Vis光谱法确认了所有新合成的化合物的结构。用稀释法测试了新化合物对单核细胞增生李斯特菌,金黄色葡萄球菌,大肠杆菌和铜绿假单胞菌PAO1的抗菌活性。所有化合物对革兰氏阳性细菌均具有选择性活性。特别是化合物4d,4h和4i对S的活性最高。金黄色葡萄球菌和单核细胞增生李斯特菌,MIC4值分别达到4μg/ mL和8μg/ mL。抗菌活性与化合物结构之间的关系表明,羟基的存在似乎对酚类化合物的抗菌活性至关重要。
