Cucurbitacin B and E are a class of highly oxidized cucurbitane-type tetracyclic triterpenoids extracted from cucurbit plants such as melon, cucumber, watermelon, loofah, and so on. In anticancer studies, they have shown proliferation inhibition and antimetastatic activity against a variety of cancer cells, and their mechanisms may be related to the destruction of the cytoskeleton, interference with F-actin, induction of cell cycle arrest, induction of apoptosis and autophagy, promotion of DNA damage, induction of reactive oxygen species (ROS) formation, and induction of ferroptosis. This article provides a review of the antitumor effects and mechanisms of cucurbitacin B and E.展开更多
