A selection of 1-amino-2-arylidenamine-1,2-(dicyano)ethenes was synthesized and cyclized to 2-aryl-4,5-dicyano-1-imidazoles upon reflux in ethyl acetate/acetonitrile, in the presence of manganese dioxide. These compounds were tested for their antioxidant capacity by cyclic voltammetry, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and deoxyribose degradation assays. The minimum inhibitory concentration of all compounds was evaluated against two yeast species, and . 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.
选择了一系列 1-氨基-2-芳基亚氨基-1,2-(二氰基)乙烯，并在乙酸乙酯/乙腈回流的条件下，在二氧化锰的存在下环化成 2-芳基-4,5-二氰基-1-咪唑。通过循环伏安法、2,2-二苯基-1-苦基肼（DPPH）自由基和脱氧核糖降解测定法，测试了这些化合物的抗氧化能力。用两种酵母，和，评估了所有化合物的最小抑菌浓度。在哺乳动物成纤维细胞中测试了它们的毒性。在所合成的化合物中，有两种表现出双重抗氧化/抗真菌活性，且对成纤维细胞没有毒性作用。本工作中合成的新化合物是潜在的生化工具和/或治疗药物。
