ergosterol

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

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

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 peroxide is an inhibitor of osteoclast differentiation, which has antiviral, trypanocidal, antitumor, and antiangiogenic actions, it can stimulate Foxo3a activity by inhibiting pAKT and c-Myc and activating pro-apoptotic protein Puma and Bax to

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

Itraconazole (R51211) is a triazole antifungal agent that inhibits cytochrome P-450-dependent enzymes required for ERGOSTEROL synthesis.

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.

Lumisterol (9β,10α-Ergosterol), a steroid compound and the (9β,10α)-stereoisomer of Ergosterol, serves as a photoprotective agent shielding against UVB-induced DNA damage and exhibits 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.

Miconazole nitrate (R18134 nitrate), an imidazole antifungal agent, selectively affects the integrity of fungal cell membranes, high in ergosterol content and different in composition from mammalian cells membranes.

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.

Tioconazole (Vagistat) is a synthetic imidazole derivative, inhibits cell wall synthesis by inhibiting the biosynthesis of ergosterol or other sterols, damaging the fungal cell membrane, altering its permeability, and promoting loss of essential intracellular elements.

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
