This article presents the synthesis of a series of amides, based on the interaction of several 3-aminospirohydantoins with nalidixic acid. The target compounds were characterized by physicochemical parameters, IR, 1H and 13C NMR spectral data. The antimicrobial activity of the products obtained was determined against Gram-positive bacteria Staphylococcus aureus and Bacillus subtilis, Gram-negative
本文介绍了基于几种3-氨基螺乙胆苷与萘啶酸的相互作用的一系列酰胺的合成。通过理化参数,IR,1 H和13 C NMR光谱数据表征目标化合物。获得的产物的抗微生物活性物对革兰氏阳性细菌测定金黄色葡萄球菌和枯草芽孢杆菌,革兰氏阴性菌的大肠杆菌,绿脓杆菌和沙门氏菌奥博尼,酵母白色念珠菌和酿酒酵母和模具产黄青霉和黑曲霉。讨论了所得产物的结构与生物学活性之间的关系。发现最有效的化合物是四氢化萘(5f)和茚满(5g)衍生物,它们对测试的革兰氏阳性细菌和革兰氏阴性细菌均显示出显着的抗菌活性。
