3]oxazin-3(4H)-yl)ethane derivatives was obtained through an eco-friendly Mannich type condensation–cyclization reaction of phenols or naphthols with formaldehyde and primary amines in water at ambient temperature. Preliminary in vitro antimicrobial activity of the synthesized compounds was assessed against six pathogenic fungi, two Gram-negative and two Gram-positive bacteria. Some of the screened compounds
一系列3,4-二氢-2 H-苯并[e]-,2,3-二氢-1 H-萘[1,2-e]-,3,4-二氢-2 H-萘[2,通过生态友好的Mannich获得了1-e] [1,3]恶嗪和1,2-双(3,4-二氢苯并[e] [1,3]恶嗪-3(4 H)-基)乙烷衍生物室温下水中的酚类或萘类与甲醛和伯胺的缩合型环化反应。评估了合成化合物对六种致病真菌,两种革兰氏阴性细菌和两种革兰氏阳性细菌的初步体外抗菌活性。一些筛选出的化合物显示出显着的体外抗菌作用。铅化合物的细胞毒活性(2m,通过MTT法测定针对小鼠成纤维细胞系(L929)的2n,3c和3d)。分析结果表明,这些分子以25μg/ mL的浓度提供了L929细胞显着的活力(> 90%)。
