Gypsetin can inhibit acylcoenzyme A, cholesterol acyltransferase (ACAT) activity, inhibit rat liver microbody ACAT with an IC50 of 18 μM, and its action is competitive with oleoyl-COA substrate, Ki value is 5.5 μM. Gypsetin also inhibits Oleic acid from forming cholesterol esters with an IC50 of 0.65 μM[1].
