synthesize a series of 2-(((2-ether)amino)methylene)-dimedone derivatives and evaluate the synthesized compounds for antimicrobial activity. Compound library was synthesized by reaction with alkyl, alkenyl, alkynyl and alicyclic bromo-compounds. Characterization of the synthesized compounds was performed by 1H NMR, 13C NMR and mass spectral techniques. The compounds were evaluated for their antibacterial
设计该研究的目的是合成一系列2-((((2-醚)氨基)亚甲基)二甲酮衍生物,并评估合成的化合物的抗菌活性。通过与烷基,烯基,炔基和脂环族溴化合物反应合成化合物库。合成的化合物的表征通过1 H NMR,13 C NMR和质谱技术进行。评价了这些化合物对革兰氏阳性(金黄色葡萄球菌,枯草芽孢杆菌,产孢梭菌)和革兰氏阴性细菌(铜绿假单胞菌,大肠杆菌)的抗菌活性。还评估了这些化合物对真菌(烟曲霉,产黄青霉,尖孢镰刀菌,白色念珠菌)和霉菌(黑曲霉和米曲霉)的活性。肉汤微稀释法和稍作修改的CLSI指南分别用于测定抗菌和抗真菌活性。尽管四种化合物(4i,4j,4k和4l)显示出良好的抗菌活性,但发现该化合物4k是该系列中最活跃的化学型。发现化合物4k对金黄色葡萄球菌,蜡状芽孢杆菌和枯草芽孢杆菌细菌菌株具有比对照环丙沙星低一个稀释度的活性。化合物4k的抗菌活性与环丙沙星对化脓性链球菌和黄褐肉芽胞杆菌相当。与
