Twenty-six enamines were synthesized to screen for the antimicrobial activity. Out of the compounds, 22 were reported for the first time. Their chemical structures including E/Z-configurations were clearly determined by 1H NMR, ESI mass spectra and elemental analyses, coupled with three selected single-crystal structures. In general, these synthetic compounds were shown to be more effective to inhibit
合成了二十六个烯胺以筛选抗微生物活性。在这些化合物中,首次报告了22种化合物。通过1H NMR,ESI质谱和元素分析清楚地确定了它们的化学结构,包括E / Z构型,以及三个选定的单晶结构。通常,这些合成化合物显示出比真菌更有效的抑制细菌生长。最具活性的化合物(E)-3-(4-羟基苯基氨基)-2-(4-氯苯基)丙烯酸乙酯(1b)对MIC为0.5 microg / mL的金黄色葡萄球菌ATCC 6538和荧光假单胞菌显示出显着的抗菌活性ATCC 13525的MIC为1.5 microg / mL,分别优于阳性对照青霉素和卡那霉素。构效关系分析表明:关于A环,在3,5-位取代的化合物比2,4-位取代的衍生物更具活性,并且在2-位的卤素取代的类似物具有与在4-位取代的衍生物基本相同的活性。氮原子周围空间位阻的增加导致无活性的化合物。
