derivatives have been synthesized by reaction of 1-(2,5-dimethyl-furan-3-yl)-ethanone with corresponding active aldehyde in ethanolic NaOH in microwave oven. The structure of these compounds was established by elemental analysis, IR, 1H NMR, 13C NMR, and EI-MS spectral analysis. The anti-bacterial activity of these compounds was first tested in vitro by the disc diffusion assay against two Gram-positive
查耳酮衍生物已通过 1-(2,5-二甲基-呋喃-3-基)-乙酮与相应的活性醛在 NaOH 乙醇中在微波炉中反应合成。这些化合物的结构通过元素分析、IR、1H NMR、13C NMR和EI-MS光谱分析确定。这些化合物的抗菌活性首先通过圆盘扩散试验对两种革兰氏阳性菌和两种革兰氏阴性菌进行体外试验,然后以标准药物氯霉素为参考确定最低抑菌浓度(MIC)。结果表明,含吡唑的查耳酮(化合物 8)对两种类型的细菌(革兰氏阳性和革兰氏阴性)的抑制效果都优于氯霉素。
