antibacterial activity against both Gram-positive and Gram-negative bacteria. Evaluation of the synthesized scaffolds revealed a good to excellent antioxidant activities (25.1–87.8 %) using ABTS inhibitory potency. Among these compounds, 3a, 3b, 8b and 11 displayed higher antioxidant activities (83.5–87.8 %) comparing with (Ascorbic acid, 88.0%). The obtained results showed that imidazole, pyrazole and
本研究涉及合成含有茚并[1,2- d ]咪唑、茚并[1,2- e ]三嗪、茚并[1,2- c ]吡唑和茚并[1,2- b]吡咯化合物。合成策略基于茚三酮与各种含氮亲核试剂(即:二芳基硫脲、4-芳基氨基硫脲、苯肼/杂芳基醛和烯胺试剂)的反应。通过考虑元素和光谱分析的数据,阐明了合成的基于稠合茚酮的杂环。针对两种革兰氏阳性(枯草芽孢杆菌和金黄色葡萄球菌)和两种革兰氏阴性(铜绿假单胞菌和大肠杆菌)细菌检查了合成支架的抗菌活性。在合成的杂环中,3a、3b、8b和11对革兰氏阳性菌和革兰氏阴性菌均表现出优异的抗菌活性。使用 ABTS 抑制效力,对合成支架的评估显示出良好到极好的抗氧化活性 (25.1–87.8 %)。在这些化合物中,3a、3b、8b和11显示出比(抗坏血酸,88.0%)更高的抗氧化活性(83.5-87.8%)。所得结果表明,咪唑、吡唑和吡咯环以及苯环上的甲氧基和酰胺取代基增加了相关杂
