| | FILIPIN III Usage And Synthesis |
| Description | Cholesterol is both an important structural component of cell membranes and an early intermediate in hormone and bile acid biosynthesis. The localization and measurement of cholesterol in cells is therefore of great interest. Filipin is the collective name given to four isomeric polyene macrolides isolated from cultures of S. filipinensis; Filipin III is the predominant isomer and the one used in most studies. Filipin binds to cholesterol in membranes, forming ultrastructural aggregates and complexes which can be visualized by freeze-fracture electron microscopy. The binding of cholesterol also decreases the intrinsic fluorescence of Filipin, and this property has also been used to detect cholesterol in membrane fractions. | | Uses | Filipin III is the major component of the filipin complex, a family of pentaene antifungal metabolites first isolated from Streptomyces filipinensis and reported by researchers at Upjohn in 1955. Filipin III is a potent broad spectrum antifungal agent that also exhibits antitumor and antiviral activities. Filipin III acts by binding cell membrane sterols, disrupting membrane integrity. This sterol selectivity has led to the use of filipin III as a routine diagnostic probe for quantifying cholesterol in mammalian cells. | | Uses | Cholesterol is both an important structural component of cell membranes and an early intermediate in hormone and bile acid biosynthesis.

The antifungal mechanism of action may be due to altering membrane permeability and associated functions by binding to membrane sterols. Filipin inhibits prion protein (PrP) endocytosis and causes the release of PrP from the plasma membrane. | | storage | Store at -20°C | | References | [1] G B SMEJKAL H F H.
