生物活性
Oenothein B is a dimeric macrocyclic ellagitannin and has widely pharmacological activities, including antioxidant, anti-inflammatory, antifungal, anti-HCV, and antitumor properties. Oenothein B is a potent and specific inhibitor of poly(ADP-ribose) glycohydrolase[1][2].
体外研究 (In Vitro)
Oenothein B (15-45 µM; 12-72 hours) has a dose- and time-dependent inhibition rate effect on A549 cells in the range of 12 hours, 24 hours, 36 hours, 48 hours, 60 hours and 72 hours of exposure[1]. Oenothein B (15-45 µM; 24 hours) effectively inhibits the proliferation of A549 cells by inducing apoptosis and arresting cells at G1 stage[1]. Oenothein B (15-45 µM; 24 hours) not only increases the level of intracellular reactive oxygen species (ROS), but also induces the upregulation of intracellular apoptotic triggers (cleavage caspase-3, PARP, cytochrome c level in the cytosol, Bax)[1]. A549 cells[1] 15 µM, 30 µM and 45 µM 24 hours Arrested cells in the G1 phase. A549 cells[1] 15 µM, 30 µM and 45 µM 24 hours BAX, p53, cytochrome c (cytoplasm) and PARP were unregulated significantly; Anti-apoptotic Bcl-2 was decreased significantly in a concentration-dependent manner.
