chromans substituted at positions 2 or 5 by catechol derivatives were synthesized, and their activity against oxidative stress induced cellular damage was studied. Specifically, the ability of the new molecules to protect cultured cells from H(2)O(2)-induced DNA damage was evaluated using single cell gel electrophoresis (comet assay), while the neuroprotective activity of the new compounds against oxidative
合成了三类在邻苯二酚衍生物在2或5位取代的苯并二氢吡喃,并研究了它们对氧化应激诱导的细胞损伤的活性。具体来说,使用单细胞凝胶电泳(彗星试验)评估了新分子保护培养的细胞免受H(2)O(2)诱导的DNA损伤的能力,而新化合物针对氧化应激诱导的神经保护活性被编程使用谷氨酸-challanged海马HT22细胞研究了细胞死亡。大多数新化合物比槲皮素具有更强的神经保护作用。5-取代的苯并二氢吡喃类似物,例如咖啡酰胺12和16和二氢二苯乙烯类似物24,分别对Jurkat T细胞和HT22细胞中H(2)O(2)-和谷氨酸诱导的损伤最有效。
