General description

Gliotoxin is the mycotoxin produced by Aspergillus fumigatus (AF). It is a hydrophobic metabolite of 326 Da.

Chemical structure: epipolythiodioxopiperazine

Application

Gliotoxin has been used for performing cytotoxicity tests in adenocarcinomic human alveolar basal epithelial (A549) cell lines.

Nicht-kompetitiver Hemmer der chymotrypsin-ähnlichen Aktivität des 20S Proteasoms in vitro.

Biochem/physiol Actions

Gliotoxin is associated with immunosuppression. It is an antiphagocytic and immunomodulating agent that acts by blocking membrane thiol groups. It is implicated in the pathophysiology of invasive aspergillosis (IA) and impacts functional T-cell responses. Gliotoxin in observed in the sera of cancer patients with IA infection.
