Aspergillius janus, Aspergillus niger and Pencillium glabrum, respectively. The antimicrobial behaviour of the bispyrazolines 3a–3h is found to be dependent on the length of internal spacer unit. Synthesis and antimicrobial behaviour of the bispyrazolines built around the aliphatic chains have been described. The antimicrobial behaviour of these bisheterocyclic compounds is found to be dependent on the
双吡唑啉3a - 3h围绕不同长度的烷基链构建,是由比沙可康烯与苯基肼的环化反应合成的。从苯乙酮与各种双醛1a - 1h的Claisen-Schmidt反应中获得了Bischalcones 2a - 2h。通过IR,1 H-NMR,13 C-NMR,质量(ESI)和元素分析来表征中间的双缩水锥和最终的双杂环化合物。还评估了合成化合物的抗细菌和抗真菌活性,对肺炎克氏杆菌,铜绿假单胞菌,大肠埃希菌,金黄色葡萄球菌,枯草芽孢杆菌和janjan曲霉,黑曲霉和延寿草。发现双吡唑啉3a – 3h的抗菌性能取决于内部间隔单元的长度。 已经描述了围绕脂族链构建的双吡唑啉的合成和抗菌性能。发现这些双杂环化合物的抗微生物行为取决于内部间隔单元的长度。
