摘 要:脱氢枞胺及降解脱氢枞胺分别与杂环甲醛在乙醇溶剂中缩合合成了6个松香基Schiff碱杂环衍生物(a1/a2、b1/b2、c1/c2),并对产物结构进行了IR、1H NMR光谱表征确证。通过体外最低抑菌活性测试,结果表明,化合物c1和c2对金黄色葡萄球菌(Staphylococcus aureus)、表皮葡萄球菌(Staphylococcus epidermidis)、绿脓杆菌(Pseudomonas aeruginosa)和产气杆菌(Bacterium aerogenes)具有显著效果,其最低抑菌浓度(the Minimum Inhibitory Concentration)均为32 μg·mL-1。

Abstract:Using ethanol as solvent six rosin-based heterocyclic Schiff bases were synthesized from the condensation reaction between dehydroabietylamine or nor-dehydroabietylamine and heterocyclic formaldehyde. Their structures were confirmed by IR and 1H NMR spectroscopy. The minimum antibacterial activities of six compounds were tested by extracorporeal experiment. The results showed that compounds (c1 and c2) were relatively ideal and their least MICs of Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa,and Bacterium aerogenes was 32 μg·mL-1.
