Gliotoxin is an immunosuppressive mycotoxin produced by pathogenic strains of Aspergillus and other fungi with diverse biological activities.{21692,21695,21694,21690,21693,21689,43859,21714} It inhibits 20S proteasomal chymotrypsin activity (IC50 = 10 μM), blocking the degradation of IκBα and preventing the activation of NF-κB.{21695,21694} Gliotoxin induces apoptosis in monocytes and dendritic cells and reduces phagocytosis by neutrophils.{21690,21693} It suppresses viral infection by Nipah and Hendra virus in HEK293T cells (IC50s = 149 and 579 nM, respectively).{21689} Under reducing conditions, gliotoxin inhibits leukotriene A4 hydrolase (LTA4H; Item No. 10007817) epoxide hydrolase activity, but not aminopeptidase activity, and leukotriene B4 (LTB4; Item No. 20110) synthesis in neutrophils and monocytes.{43859} In vivo, gliotoxin (5 mg/kg) reduces LTB4 plasma levels and blocks peritoneal neutrophil infiltration in a mouse model of peritonitis induced by zymosan A (Item No. 21175). It also inhibits geranylgeranyltransferase I and farnesyltransferase (IC50s = 17 and 80 μM, respectively).{21714}
