ergosterol

Ergosterol is the major sterol in fungi and has anti-inflammatory, antioxidant and antiproliferative properties.

Ergosterol peroxide (NSC 31324) is a derivative from mushrooms with anti-tumor, pro-apoptotic anti-mycobacterial and anti-proliferative activities.Ergosterol peroxide has anti-inflammatory and antioxidant activities and is toxic to parasites.

Ergosterol glucoside is a natural product from Rehmannia glutinosa.

Ergosterol peroxide exhibits anti-cancer, amoebicidal, anticomplementary, antibacterial, antiviral, anti-oxdiant, and anti-melanogenic activities. Ergosterol peroxide could as an anti-atherosclerosis agent, it exhibits hACAT-1 and Lp-PLA2 inhibitory effec

Ergosterol Acetate (Ergosta-5,7,22-trien-3-beta-yl acetate) is one of the acetate derivatives of Ergosterol from Monascus anka.

Dehydroergosterol (DHE) is a naturally occurring fluorescent sterol analog that is a compound for real-time detection elaboration of the sterol environment and intracellular sterol transport in organisms. Dehydroergosterol is a cholesterol mimetic that binds to cholesterol-binding proteins and can be used for real-time imaging of living cells. Dehydroergosterol is a cholesterol mimetic that binds to cholesterol-binding proteins and can be used for real-time imaging of living cells.

9,11-Dehydroergosterol peroxide is a useful organic compound for research related to life sciences. The catalog number is T124072 and the CAS number is 86363-50-0.

5,6-Epoxyergosterol is derived from the endophytic fungus Phyllosticta capitalensis.

22,23-Dihydroergosterol is an orally active natural product that can be isolated from *Flammulina velutipes* [1].

24(28)-Dehydroergosterol is a natural product that can be used in related research in the field of life sciences. Its product number is TN8672.

Amphotericin B (NSC-527017) is a polyene antifungal agent with broad-spectrum activity against many fungal species. Amphotericin B irreversibly binds to ergosterol and disrupts the integrity of cell membranes, resulting in antifungal activity.

Ergocalciferol (Vitamin D2 (Calciferol)) is a derivative of ergosterol formed by ultraviolet rays breaking of the C9-C10 bond with a strong inhibitory effect against bladder tumor promotion by sodium saccharin, and it induces cell differentiation in leukemia cells. Vitamin D2 is an inhibitor of DNA Polymerase.

Terbinafine (TDT 067) is a synthetic allylamine derivative with antifungal activity. Terbinafine exerts its effect through inhibition of squalene epoxidase, thereby blocking the biosynthesis of ergosterol, an important component of fungal cell membranes. As a result, this agent disrupts fungal cell membrane synthesis and inhibits fungal growth.

PF-1163B is an antifungal agent form Penicillium sp. II. PF-1163B inhibits ergosterol (ERG) synthesis with IC50 value of 34 ng/ml. PF-1163B showed potent growth inhibitory activity against pathogenic fungal strain Candida albicans but did not show cytotox

Lumisterol (9β,10α-Ergosterol), the (9β,10α)-stereoisomer of Ergosterol, is a steroid compound that acts as a photoprotective agent against UVB-induced DNA damage and demonstrates anti-proliferative activities[1].

Withaphysalin R (compound 5), a withanolide derived from the Solanaceae family, possesses an ergosterol-based steroid ester structure. This compound exhibits notable activities such as cytotoxic, immunosuppressive, antitumor, anti-inflammatory, anticonvulsive, and antioxidant effects [1].

PF-1163A, a depsipeptide antifungal compound isolated from Penicillium, blocks ergosterol synthesis with an IC50 of 12 ng/ml. This compound specifically inhibits the enzyme ERG25p, a C-4 methyl oxidase in the ergosterol biosynthetic pathway, leading to its antifungal activity. Notably, in Saccharomyces cerevisiae modified to express ERG biosynthesis genes, PF-1163A exhibits an inhibition concentration (MIC value) of 12.5 µg/ml against ERG25p, though strains overexpressing ERG25p show resistance. Additionally, PF-1163A effectively suppresses the growth of Candida albicans (MIC = 8 µg/ml), without affecting other Candida species, Aspergillus fumigatus, or HepG2 cells. Remarkably, it enhances the efficacy of fluconazole against azole-resistant C. albicans strains, showing a significant decrease in MICs (1 and 0.0078 µg/ml alone and in combination, respectively). PF-1163A distinguishes itself from PF-1163B by its more polar nature.

Nystatin A1, a polyene macrolide (antibiotic), is isolated from the Streptomyces noursei bacterium. It functions by binding with ergosterol on fungal cell membranes, enhancing membrane permeability, and consequently causing leakage of cellular contents, which inhibits fungal growth and reproduction.
