Topovale 是一种有效的拓扑异构酶 I 抑制剂。Topovale 抑制缺氧介导的缺氧诱导因子 1alpha 的积累。 Topovale 对一组癌细胞表现出低 nM 细胞毒性。与 P388 细胞相比，在 CPT 抗性拓扑异构酶 I (TOP1) 缺陷的 P388/CPT45 细胞中，Topovale 细胞毒性和 Topovale 诱导的细胞凋亡减少了 >100 倍。

Topovale is a potent inhibitor of topoisomerase I. Topovale inhibits hypoxia-mediated accumulation of hypoxia-inducible factor-1alpha. Topovale exhibited low nM cytotoxicity against a panel of cancer cells. Topovale cytotoxicity as well as Topovale-induced apoptosis was reduced >100-fold in CPT-resistant topoisomerase I (TOP1)-deficient P388/CPT45 cells as compared with P388 cells.
