methoxy (5o), were found to exhibit excellent to good antimicrobial activities (MIC value 9–18 μM) against Staphylococcus aureus MTCC 96, Staphylococcus aureus MLS-16 MTCC 2940 and Bacillus subtilis MTCC 121. The products were also screened for anti-biofilm and MBC (Minimum Bactericidal Concentration) activities which exhibited promising activities.
席夫碱类似物(5a - q)的新型文库是由12-氨基十八烷基-9-烯酸甲酯与不同取代的芳族醛缩合而合成的。通过光谱技术(FT-IR,1 H NMR,13 C NMR,ESI-MS和HRMS)对合成的化合物进行了全面表征。筛选具有不同取代基的席夫碱类似物对7种不同细菌菌株的体外抗菌活性。其中,具有吸电子取代基的化合物为氯(5a),具有给电子取代基的化合物为羟基(5n)和甲氧基(5o)。)对金黄色葡萄球菌MTCC 96,金黄色葡萄球菌MLS-16 MTCC 2940和枯草芽孢杆菌MTCC 121表现出优异的抗菌性能(MIC值为9-18μM)。还对产品进行了抗生物膜和MBC筛选(最低杀菌浓度)活动,表现出良好的发展前景。
