Anti-leukemic activity of semisynthetic derivatives of lupeol.

In our previous work, lupeol was isolated from aerial parts of and modified by semisynthetic approach. The purpose of this study was to investigate the cytotoxicity of lupeol and its derivatives previously prepared on the human K562 acute myeloid leukemia cell and human Jurkat acute lymphoid leukemia cell . Compounds 3β-hydroxylup-20(29)-en-30-al (), lup-20(30)-en-3β,29-diol (), 3β-acetoxylup-20(29)-en-30-al () and 3β-acetoxy-30-hydroxylup-20(29)-ene () presented cytotoxicity with IC ranging from 11.
