3-Oxo-cinobufagin (compound 8) is a potential anticancer compound that can be isolated from the broth of M. spinosus by high-performance liquid chromatography. Compared to other isolated compounds, the hydroxyl group at the C-5 position of 3-Oxo-cinobufagin is further oxidized or isomerized, significantly reducing its cytotoxic activity against most cell lines (except HEL), while increasing its activity against the BEL cell line. The IC50 values of 3-Oxo-cinobufagin's cytotoxicity against cancer cells are: 71.3 μM (HepG2), 90.2 μM (SMMC-7221), 0.11 μM (BEL-7402), 72.5 μM (K562), 5.3 μM (HL-60), and 12 nM (HEL)[1]. | [References]
