A series of 3-[3-(substituted phenyl)-1-phenyl-1H-pyrazol-5-yl]-2H-chromen-2-one (4a-k) were synthesized by reaction of 3-[2,3-dibromo-3-(substituted phenyl)propanoyl]-2H-chromen-2-one (3 a-k) with phenyl hydrazine in presence of triethylamine in absolute ethanol, characterized by spectral data and screened for their in vitro antibacterial activity against gram-positive and gram-negative bacteria.
通过3- [2,3-的反应合成了一系列的3- [3-(取代的苯基)-1-苯基-1H-吡唑-5-基] -2H-铬-2-(4-a-k)。在无水乙醇中三乙胺存在下,用苯基肼制备二溴-3-(取代的苯基)丙酰基] -2H-铬-2-酮(3 ak),其特征在于光谱数据,并筛选了它们对革兰氏阳性和克雷伯氏菌的体外抗菌活性。革兰氏阴性细菌。在该系列中,与参考标准药物环丙沙星相比,化合物4d,4h和4i对测试的细菌菌株显示出令人鼓舞的抗菌活性。
