Tephrosin
Tephrosin is an anti-cancer rotenoid isolated from the plant, Tephrosia vogelii.
Natural rotenoids display a wide range of biological activities, from strong pesticidal and insecticidal activities to therapeutically intriguing anticancer properties. Tephrosin has been shown to induce caspase-independent apoptosis, and internalization and degradation of inactivated EGFR and ErB2 in human colon cancer cells.
