TopoisomeraseIIinhibitor 3 (Compound 6 h) is an acridone derivative that acts as a Type II DNA topoisomerase (topo II) inhibitor. It specifically inhibits the topo IIα β subtypes, with an IC50 value of 0.17 μM for topo IIα and 0.23 μM for topo IIβ. This compound elicits significant DNA damage and induces apoptosis by triggering the loss of mitochondrial membrane potential [1].
Topoisomerase I IIinhibitor 3 (化合物7) 是拓扑异构酶 I (Topo I)和 II (Topo II)的有效双抑制剂。 通过抑制 PI3K Akt mTOR 信号通路,Topoisomerase I IIinhibitor 3抑制细胞增殖、侵袭和迁移,诱导细胞凋亡(apoptosis)。Topoisomerase I IIinhibitor 3 在肝癌中具有研究价值。
TopoisomeraseIIinhibitor 14 是一种有效的拓扑异构酶 II 抑制剂,具有抗癌活性和抗氧化活性。TopoisomeraseIIinhibitor 14 诱导细胞凋亡,并将细胞周期阻滞在 S 期。TopoisomeraseIIinhibitor 14 可降低 GSH、MDA 和 NO 的量。
