Biochem/physiol Actions

Filipin is a polyene macrolide antibiotic and antifungal. The antifungal mechanism of action is unclear but may be due to altering membrane permeability. Filipin binds to model crystalline phase lipid bilayers containing cholesterol, and to liquid phase bilayers with or without cholesterol, in an orientation that forms membrane pores.It both inhibits prion protein (PrP) endocytosis and causes the release of PrP from the plasma membrane.
