23-hydroxyursolic acid Induces Apoptosis of human leukemia HL-60 cells

  • Published : 2002.10.01

Abstract

We found that 23-hydroxyursolic acid, triterpenoid was isolated from Cussonia bancoensis have a significant cytotoxic activity against HL -60 human promyelocytic leukemia cells. The IC of 23-hydroxyursolic acid was 32.83 $\mu$M. These anti-proliferative activity was due to induction of apoptosis. The effect of apoptosis was identified by DNA laddering, DAPI assay. PI staining, and Annerxin V-FITC binding assay. (omitted)
