Efficient syntheses of some new substituted pyrazoline derivatives linked to substituted benzimidazole scaffold were performed by multistep reaction sequences. All the synthesized compounds were characterized using elemental analysis and spectral studies (IR, 1D/2D NMR techniques and mass spectrometry). The synthesized compounds were screened for their antimicrobial activity against selected Gram-positive
通过多步反应序列可以高效合成一些与取代的苯并咪唑支架连接的新的取代的吡唑啉衍生物。使用元素分析和光谱研究(IR,1D / 2D NMR技术和质谱)对所有合成的化合物进行表征。筛选合成的化合物对所选革兰氏阳性和革兰氏阴性细菌以及真菌菌株的抗菌活性。在1-苯基吡唑啉环(15、16和17)的C5处带有卤素取代的苯基的化合物显示出显着的抗菌活性。在筛选的化合物中,有17种显示出对细菌菌株的最有效的抑制活性(MIC = 64 μgmL-1)。除吡唑啉-1-碳硫嘧啶21外,发现被测化合物对白色念珠菌菌株几乎没有活性,
