      Cinobufotalin is one of the bufadienolides prepared from toad venom; has anticancer activity.;IC50 value:;Target:;In vitro: Cinobufotalin(CB) caused significant DNA fragmentation, decrease of MMP, and an increase in the intracellular Ca(2+) ion and ROS production. In addition, CB induced upregulation of Fas protein, proteolytic activation of cytochrome c, caspase-2, -3, -8 and -9 together with the activation of Bid and Bax [1]. cinobufotalin displayed considerable cytotoxicity against lung cancer cells (A549, H460 and HTB-58 lines) without inducing significant cell apoptosis. cinobufotalin mainly induces Cyp-D-dependent non-apoptotic death in cultured lung cancer cells [2]. cinobufotalin (at nmol/L) significantly inhibited HCC cell growth and survival while inducing considerable cell apoptosis. Further, cinobufotalin inhibited sphingosine kinase 1 (SphK1) activity and induced pro-apoptotic ceramide production. cinobufotalin inactivated Akt-S6K1 signaling in HepG2 cells, which was a MedChem Express HY-N0880
