Description
Schisandrol B is a lignan originally isolated from
S. chinensis that has hepatoprotective activity. It increases the expression of pregnane X receptor (PXR) target genes involved in bile acid metabolism, including
Cyp3a11,
Ugt1a1,
Oatp2, and
Mrp3 in mouse liver and
CYP3A4,
UGT1A1, and
OATP2 in HEK293T cells. It also protects against lithocholic acid-induced hepatic necrosis and intrahepatic cholestasis in wild-type, but not
Pxr-null, mice and decreases mortality in a mouse model of cholestasis when administered at a dose of 100 mg/kg twice per day. It also promotes liver regeneration following partial hepatectomy and protects against hepatotoxicity induced by acetaminophen .
Chemical Properties
White powder
Uses
Schizandrol B exhibits potent protective effects of on ET-1-induced dysfunctional human-induced pluripotent stem cell-derived cardiomyocytes (hiPS-CMs). Anti-cholestasis effect.
in vivo
Schisandrol B (12.5-200mg/kg; oral administration; seven times with an interval of 12hours) pretreatment significantly attenuates the increases in alanine aminotransferase and aspartate aminotransferase activity, and prevents elevated hepatic malondialdehyde formation and the depletion of GSH in a dose-dependent manner. Schisandrol B abrogates APAP-induced activation of p53 and p21, and increases expression of liver regeneration and antiapoptotic-related proteins such as cyclin D1 (CCND1), PCNA, and BCL-2[1].

| Administration: | Oral administration; seven times with an interval of 12hours |
| Result: | Showed a protective effect against APAP-induced liver injury in mice. |
