An ent-kaurene diterpene enhances apoptosis induced by tumor necrosis factor in human leukemia cells.
Some antitumor agents, including tumor necrosis factor-alpha (TNF-alpha) and camptothecin (CPT), often cause resistance of tumor cells to antitumor agents through activation of the nuclearExpand

A comparison of apoptosis and necrosis induced by ent-kaurene-type diterpenoids in HL-60 cells.
We previously reported that ent-11alpha-hydroxy-16-kauren-15-one (KD) induces apoptosis through a caspase-dependent pathway and the induction of apoptosis is dependent on its enone group in humanExpand
