were screened in vitro and evaluated for both their antibacterial and antifungal activities. MIC data of the novel dye systems and their respective precursors showed significant antimicrobial activity against most tested organisms. Some compounds exhibited comparable or even higher efficiency than selected standards. Dyes were applied at 5% depth for disperse dyeing of nylon, acetate and polyester fabrics
合成了一系列基于共轭烯胺酮和/或烯胺腈部分的新型多官能化无环和杂环染料前体及其各自的偶氮(腙)对应染料和染料前体。染料及其前体基于 2-氰基-N-(3-氰基-4,5,6,7-四氢苯并[b]噻吩-2-基)-乙酰胺、2-乙氧基羰基-N-(3-氰基) -4,5,6,7-四氢苯并[b]噻吩-2-基)-乙酰胺或2-苯基氨基甲酰基-N-(3-氰基-4,5,6,7-四氢苯并[b]噻吩-2-基)-乙酰胺系统作为前体。后一种化合物用于合成多官能噻吩-、噻唑-、吡唑、吡啶-、嘧啶-、恶嗪-以及无环部分。染料和染料前体通过元素分析和光谱方法表征。所有染料及其前体都在体外进行了筛选,并评估了它们的抗菌和抗真菌活性。新型染料系统及其各自前体的 MIC 数据显示对大多数测试生物具有显着的抗菌活性。一些化合物表现出与选定标准相当甚至更高的效率。染料以 5% 的深度用于尼龙、醋酸纤维和涤纶织物的分散染色。测量和评估了它们
