evaluated for in vitro antimicrobial activity against a panel of reference strains of microorganisms, including Gram-positive bacteria, Gram-negative bacteria and fungi belonging to yeasts Candida spp. Our antimicrobial screening results indicated that some of the newly obtained compounds showed high antibacterial activity, especially against Gram-positive bacteria. Among them, the activity of compounds 1
摘要在本文中,我们描述了我们合成的十二种3-羟基-2-萘酰肼衍生物(六种硫代氨基脲和六种1,2,4-三唑-3-硫酮)。硫代氨基脲衍生物是通过3-羟基-2-萘肼与适当的异硫氰酸酯的缩合反应制备的。通过相应的硫代氨基脲衍生物在碱性介质中的环化反应合成1,2,4-三唑-3-硫酮。所有获得的化合物均已通过1 H NMR和13 C NMR光谱进行了分析,并评估了其对一系列参考微生物的体外抗菌活性,这些参考菌株包括革兰氏阳性细菌,革兰氏阴性细菌和属于酵母假丝酵母的真菌spp。我们的抗菌筛选结果表明,一些新获得的化合物显示出很高的抗菌活性,尤其是对革兰氏阳性细菌。其中,化合物的活性1,2和4是中等至强对葡萄球菌。除此之外,化合物1和2的抗蜡样芽孢杆菌ATCC 10876活性比头孢呋辛高两倍,比氨苄西林高四倍。 图形概要
