产品介绍
Description: 4-oxo-27-TBDMS Withaferin A is a derivative of the steroidal lactone withaferin A that has anticancer activity. It is cytotoxic to A2780 ovarian cancer cells but not to carboplatin-resistant A2780 cells. It is selective for A2780 cells over non-cancerous ARPE19 cells. 4-oxo-27-TBDMS Withaferin A induces DNA fragmentation in A2780 cells.
