Biological Activity
Reversible, competitive inhibitor of sterol regulatory element-binding protein (SREBP) site 1 protease (IC50 = 0.175 μM). Selective for site 1 protease against a panel of serine proteases. Inhibits rate of cholesterol synthesis in CHO cells (IC50 = 0.53 μM). Also displays antiviral activity. Cell permeable.
