(±)-Norcantharidin ((±)-NCTD) is a compound possessing anti-angiogenetic activity with potential use in anti-cancertherapy. (±)-Norcantharidin could prevent tumorigenesis by inhibiting cell proliferation, inducing apoptosis and the cell cycle arrest, and anti-angiogenic effects^[1]. In Vitro: (±)-Norcantharidin ((±)-NCTD) inhibits HMC cell proliferation, induces apoptosis, and affects the cell cycle^[1].
