| Description | The oxygenated sterols( 26-oxygenosterols ganoderol A, ganoderol B, ganoderal A, and ganoderic acid Y) from G. lucidum can inhibit cholesterol biosynthesis via conversion of acetate or mevalonate as a precursor of cholesterol. |
| In vitro | We report the isolation and identification of the 26-oxygenosterols ganoderol A, ganoderol B, Ganoderal A, and ganoderic acid Y and their biological effects on cholesterol synthesis in a human hepatic cell line in vitro. We also investigated the site of inhibition in the cholesterol synthesis pathway. We found that these oxygenated sterols from G. lucidum inhibited cholesterol biosynthesis via conversion of acetate or mevalonate as a precursor of cholesterol. By incorporation of 24,25-dihydro-[24,25-3H2]lanosterol and [3-3H]lathosterol in the presence of ganoderol A, we determined that the point of inhibition of cholesterol synthesis is between lanosterol and lathosterol. |
