Silybin B

• Description:

  Silybin B (Silibinin B) is an orally active 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 (HY-17394) -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[1][2][3].
