Fungal Sterols

Fungal sterols, such as ergosterol and lanosterol, are essential components of fungal cell membranes, playing an irreplaceable role in maintaining the structure and function of the cell membrane. Creative Biolabs focuses on addressing challenges in drug delivery, with fungal sterol liposomes being one of our specialized research areas.

Fungal Sterols as Substitutes for Cholesterol in Liposomes

Cholesterol, a derivative of perhydrocyclopentanophenanthrene, is an important component of animal cell membranes. To improve membrane stability in liposomes, cholesterol is frequently utilized as a membrane structure modulator because of its capacity to decrease the fluidity of phospholipid bilayers. However, high cholesterol utilization can raise the risk of atherosclerosis, coronary heart disease, and other cardiovascular diseases.

Fungal sterols, structurally similar to cholesterol, are believed to modulate cell membranes like cholesterol, exerting anti-inflammatory, antimicrobial, immunomodulatory, and cholesterol-lowering effects. Substituting fungal sterols for cholesterol in liposomes can not only reduce the health risks associated with cholesterol but also confer therapeutic properties to the liposomes themselves. Furthermore, encapsulating drugs within fungal sterol-containing liposomes may result in a synergistic interaction between the drugs and fungal sterols, potentially improving the therapeutic efficacy of the original liposomes (without fungal sterols). Fungal sterols have already replaced cholesterol and are widely employed in the development of liposomes used in pharmaceuticals, cosmetics, and related fields.

Ergosterol

The most abundant sterol in fungal cell membranes, such as those of yeast and mushrooms, is ergosterol, which is essential for preserving membrane fluidity, integrity, and cellular viability. It has a similar structure to sterols like cholesterol, but its ring structure has two double bonds, whereas cholesterol and other sterols only have one. Liposomes containing ergosterol have higher stability than conventional liposomes, which protects drugs from degradation in the gastrointestinal system. This impact is affected by the amount of ergosterol present, and Creative Biolabs will help you locate the best ergosterol content to advance your research.

Lanosterol

Lanosterol is also a primary sterol present in fungal cell membranes. Substituting it for cholesterol in liposomes provides properties similar to cholesterol without the associated health risks of cholesterol.
