| 1 | Novel azo dyes derived from 8-methyl-4-hydroxyl-2-quinolone:Synthesis,UV-vis studies and biological activity显示文摘In this study,N,N'-di-(2-methylphenyl)malonamide was synthesized and reacted with polyphosphoric acid to afford 8-methyl-4-hydroxyl-2-quinolone.Eight novel azo disperse dyes were then synthesized by linking diazotized p-substituted aniline derivatives with 8-methyl-4-hydroxyl-2-quinolone.The solvatochromism of these azo dyes in various solvents was evaluated.All the compounds were then evaluated for their antibacterial activity against four bacteria,namely.Bacillus subtilis.Micrococcus luteus, Salmonella enterica,and Pseudomonas aeruginosa.The results showed that some of these compounds have high levels of antibacterial activity. | E.O.Moradi Rufchahi H.Pouramir M.R.Yazdanbakhsh H.Yousefi M.Bagheri M.Rassa | 2013 | Chinese Chemical Letters2013，24，5： | 1 |
