Oenothein B 是聚 (ADP-核糖) 糖水解酶的特异性抑制剂。月见草素 B 具有抗氧化、抗炎、抗真菌、抗 HCV 和抗肿瘤特性。

Oenothein B is a specific inhibitor of poly(ADP-ribose) glycohydrolase. Oenothein B shows antioxidant, anti-inflammatory, antifungal, anti-HCV, and antitumor properties.(In Vitro):Oenothein B (15-45 μM; 24 hours) not only increased the level of intracellular reactive oxygen species (ROS) but also induced the upregulation of intracellular apoptotic triggers (cleavage caspase-3, PARP, cytochrome c level in the cytosol, Bax). Oenothein B (15-45 μM; 12-72 hours) had a dose- and time-dependent inhibition rate effect on A549 cells exposure. Oenothein B (15-45 μM; 24 hours) effectively inhibited the proliferation of A549 cells by inducing apoptosis and arresting cells at the G1 stage.(In Vivo):In ICR mice, Oenothein B (100-300 mg/kg; p.o.) reduced neuroinflammation in the brain during systemic inflammation.

Oenothein B (15-45 μM; 12-72 hours) has a dose- and time-dependent inhibition rate effect on A549 cells in the range of 12hours, 24hours, 36hours, 48hours, 60hours and 72 hours of exposure.Oenothein B (15-45 μM; 24 hours) effectively inhibits the proliferation of A549 cells by inducing apoptosis and arresting cells at G1 stage. 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).Concentration:15 μM, 30 μM and 45 μMIncubation Time:24hoursResult:Induced apoptosis in A549 cells.Cell Cycle AnalysisCell Line:A549 cells.Concentration:15 μM, 30 μM and 45 μMIncubation Time:24hoursResult:Arrested cells in the G1 phase.Western Blot AnalysisCell Line:A549 cells.Concentration:15 μM, 30 μM and 45 μMIncubation Time:24hoursResult:BAX, p53, cytochrome c (cytoplasm) and PARP were unregulated significantly; Anti-apoptotic Bcl-2 was decreased significantly in a concentration-dependent manner.

Oenothein B (100-300 mg/kg; p.o.) has the ability to reduce neuroinflammation in the brain during systemic inflammation in ICR mice.
