Cholesterol hemisuccinate (Cholesterol hydrogen succinate) Tris salt is a compound with hepatoprotective and anticancer activity. Cholesterol hemisuccinate Tris salt inhibits Acetaminophen (AAP) (HY-66005) hepatotoxicity, and prevents AAP-induced hepatic apoptosis and necrosis. Cholesterol hemisuccinate Tris salt inhibits DNA polymerase and DNA topoisomerase to inhibit DNA replication and repair and cell division. Cholesterol hemisuccinate Tris salt inhibits tumor growth. Cholesterol hemisuccinate Tris salt can be used for buffer preparation[1][2][3][4].
