Silybin B (Silibinin B) 是一种 Amyloid-β 聚集抑制剂及 ATR 通路激活剂,能透过血脑屏障。Silybin B 抑制 Aβ 原纤维形成并促进无定形聚集体生成,同时激活 ATR 介导的 DNA 损伤修复通路,抑制 JNK/p38 MAPK 信号。Silybin B 可减轻 Cisplatin 诱导的神经元 DNA 损伤与凋亡 (apoptosis)。Silybin B 具有抗氧化应激、调节细胞周期及神经保护活性。Silybin B 主要用于阿尔茨海默病及 Cisplatin 化疗相关神经毒性的研究。
Silybin B (Silibinin B) is an amyloid-β aggregation inhibitor and ATR pathway activator that can cross the blood-brain barrier. Silybin B inhibits Aβ fibril formation and promotes amorphous aggregate formation, while activating the ATR-mediated DNA damage repair pathway and inhibiting JNK/p38 MAPK signaling. Silybin B can reduce Cisplatin-induced neuronal DNA damage and apoptosis. Silybin B has anti-oxidative stress, cell cycle regulation and neuroprotective activities. Silybin B is mainly used in the study of Alzheimer's disease and Cisplatin chemotherapy-related neurotoxicity.
