Cholesterol hemisuccinate Tris salt (CHS-Tris) is a with hepatoprotective an 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. Thus, Cholesterol hemisuccinate Tris salt inhibits tumor growth[1][2].
