In the previous paper, we reported the differentiation inducing activities of lignoids from Arctium Fructus (the fruits of Arctium lappa L., Compositae) against mouse myeloid leukemia cells (M1). We reinvestigated the active components of this extract and isolated three new dilignans. Furthermore, structure modifications were carried out using the most active lignan (arctigenin, 1) and its structure-activity relationship was investigated. Its aliphatic esters were more effective in inducing the differentiation of M1 cels than its aromatic esters. Especially, n-decanoate, which was the most active derivative, induced more than half of the M1 cells into phagocytic cells at a concentration of 2 μM.
在上一篇论文中,我们报道了从 Arctium Fructus(菊科植物 Arctium lappa L. 的果实)中提取的木犀草素对小鼠髓系白血病细胞(M1)的分化诱导活性。我们重新研究了这种提取物的活性成分,并分离出三种新的二木质素。此外,我们还对最具活性的木犀草素(arctigenin,1)进行了结构改造,并研究了其结构与活性之间的关系。在诱导 M1 细胞分化方面,其脂肪族酯类比芳香族酯类更有效。特别是正癸酸酯,它是活性最强的衍生物,在 2 μM 的浓度下可将一半以上的 M1 细胞诱导成吞噬细胞。
