Title: Novel Anthraquinone Compounds Induce Cancer Cell Death through Paraptosis.
Authors: Tian W, Li J, Su Z, Lan F, Li Z, Liang D, Wang C, Li D, Hou H.
Abstract: Novel anthraquinone compounds that induce ER stress and paraptosis-like cell death were designed and synthesized. Compound 4a is the first organic micromolecule to kill tumor cells by only paraptosis, and its mechanism of action has been further explored. Paraptosis does not appear to involve either phosphatidylserine translocation associated with apoptosis or cell cycle arrest. The bisbenzyloxy and N-(2-hydroxyethyl)formamide structures may be two critical pharmacophores for paraptosis. Bisbenzyloxy can induce ER stress, and the N-(2-hydroxyethyl)formamide structure can increase the ratio of LC3II/I and cytoplasmic vacuolization and facilitates paraptosis. Some antitumor drugs fail to eradicate malignant cell lines with impaired apoptotic pathways; paraptosis may be a route to kill such cells and provides a new potential strategy for cancer chemotherapy.
