Fucosterol is a sterol isolated from algae, seaweed or diatoms. Fucosterol exhibits various biological activities, including antioxidant, anti-adipogenic, blood cholesterol reducing, anti-diabetic and anti-cancer activities^[1][2]. Fucosterol regulates adipogenesis via inhibition of PPARα and C/EBPα expression and can be used for anti-obesity agents development research^[1].

Fucosterol (0-50 μM; 7 days) suppresses the expression of PPARα and C/EBPα when compared to fully differentiated control adipocytes^[1]. Fucosterol shows cytotoxicity against T47D and HT29 cell lines with IC₅₀ values of 27.94 and 70.41 μg/ml, respectively^[3].
Fucosterol decreases cell HEK293, MCF-7, and SiHa cells proliferation with IC₅₀ values of 185.4, 43.3, and 34.0 µg/ml, respectively^[4].
