Description

General description

Chemical structure: epipolythiodioxopiperazine

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

Application

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

Noncompetitive inhibitor of the chymotrypsin-like activity of the 20S proteasome 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.
