species, Saccharomyces cerevisiae and Candida albicans. Their toxicity was tested in mammal fibroblasts. Among the synthesised compounds, two presented dual antioxidant/antifungal activity without toxic effects in fibroblasts. The new compounds synthesized in this work are potential biochemical tools and/or therapeutic drugs.
合成了精选的 1-氨基-2-亚芳基胺-1,2-(二氰基)乙烯 3,并在存在下在乙酸乙酯/乙腈中回流时环化为 2-芳基-4,5-二氰基-1H-咪唑 4二氧化锰。通过循环伏安法、2,2-二苯基-1-三硝基苯肼 (DPPH) 自由基和脱氧核糖降解测定来测试这些化合物的抗氧化能力。针对两种酵母菌(酿酒酵母和白色念珠菌)评估了所有化合物的最低抑制浓度。它们的毒性在哺乳动物成纤维细胞中进行了测试。在合成的化合物中,有两种具有双重抗氧化/抗真菌活性,且对成纤维细胞没有毒性作用。这项工作中合成的新化合物是潜在的生化工具和/或治疗药物。
