A novel series of 3‐[3‐(substituted phenyl)‐1‐isonicotinoyl‐1H‐pyrazol‐5‐yl]‐2H‐chromen‐2‐one derivatives 4a–k have been synthesized by the reaction of 3‐[2,3‐dibromo‐3‐(substituted phenyl) propanoyl]‐2H‐chromen‐2‐one 3a–k and isonicotinic acid hydrazide in the presence of triethylamine in absolute ethanol, characterized by spectral data and screened for their in‐vitro antibacterial activity against
通过 3-[2, 3-二溴-3-(取代苯基)丙酰基]-2H-chromen-2-one 3a-k 和异烟酸酰肼在无水乙醇中的三乙胺存在下,通过光谱数据表征并筛选它们的体外抗菌活性革兰氏阳性菌和革兰氏阴性菌。在该系列中,与参比药物氨苄西林相比,化合物 4e、4i 和 4k 显示出令人鼓舞的抗菌活性谱。
