Monascuspiloin (Monascinol), a compound extracted from rice fermented with Rhodobacter sphaeroides, exhibits antiandrogenic and antitumor activity and inhibits the proliferation of PC-3 and LNCaP.Monascuspiloin improves lipid metabolism and hepatic function in over-alcohol-addicted mice by decreasing hepatic MDA levels and increasing hepatic CAT, SOD and GSH levels.Monascuspiloin has been shown to improve lipid metabolism and hepatic function in over-alcoholized mice. Monascuspiloin regulates the transcription and protein expression of genes related to hepatic lipid metabolism and oxidative stress, and can be used to study alcohol-induced liver injury.
