In this study, 16 new 4-pyrazolyl-N-arylquinoline-2,5-dione 4 have been synthesized by the multicomponent reaction of pyrazole-4-carbaldehyde 1, Meldrum’s acid 2 and 3-aryl-5,5-disubstitutedcyclohex-2-enone 3. The structures of compounds 4 were established by the combined use of 1H NMR, 13C NMR, FT-IR and mass spectra. All the 16 compounds were tested in vitro for their bacterial and fungal activity
在这项研究中,通过吡唑-4-甲醛1,麦德鲁姆酸2和3-芳基-5,5-二取代的环己基2的多组分反应合成了16个新的4-吡唑基-N-芳基喹啉-2,5-二酮4。 -烯酮3。通过结合使用1 H NMR,13 C NMR,FT-IR和质谱确定化合物4的结构。在体外测试了这16种化合物对一系列人类病原体的细菌和真菌活性,这些人类病原体包括枯草芽孢杆菌,破伤风梭菌,肺炎链球菌,鼠伤寒沙门氏菌,霍乱弧菌,大肠杆菌,烟曲霉和白色念珠菌,采用肉汤微量稀释MIC(最低抑菌浓度)方法。发现某些化合物是针对所测试的细菌和真菌菌株的最有效的类似物。
