Based on the observed biological activities of coumarins and chalcones, we have synthesized coumarinâchalcone hybrids with the aim of evaluating their antioxidant properties and trypanocidal activity against Trypanosoma cruzi, the parasite responsible for Chagas disease. All derivatives have been proved to be good antioxidants in spite of their moderate trypanocidal activity in the epimastigote stage (clone Dm28c). Based on these results, we can conclude that compounds 4 and 5 are potential candidates for in vitro studies of their antioxidant activity. These preliminary findings encourage us to the future structural optimization of these kinds of compounds.
根据对香豆素和查尔酮的生物活性的观察,我们合成了香豆素-查尔酮杂化物,旨在评估其抗氧化性质以及对导致查加斯病的寄生虫克鲁斯锥虫的杀虫活性。尽管所有衍生物在表裂体阶段(克隆Dm28c)的杀虫活性较为温和,但它们被证明是良好的抗氧化剂。基于这些结果,我们可以得出结论,化合物4和5是进行其抗氧化活性体外研究的潜在候选者。这些初步发现鼓励我们未来对这类化合物进行结构优化。
