| Description | Gliotoxin-13C13 is intended for use as an internal standard for the quantification of gliotoxin (Item No. 11433) by GC- or LC-MS. Gliotoxin is an immunosuppressive mycotoxin produced by pathogenic strains of Aspergillus and other fungi with diverse biological activities.1,2,3,4,5,6,7,8 It inhibits 20S proteasomal chymotrypsin activity (IC50 = 10 μM), blocking the degradation of IκBα and preventing the activation of NF-κB.2,3 Gliotoxin induces apoptosis in monocytes and dendritic cells and reduces phagocytosis by neutrophils.4,5 It suppresses viral infection by Nipah and Hendra virus in HEK293T cells (IC50s = 149 and 579 nM, respectively).6 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.7 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).8WARNING This product is not for human or veterinary use. | | References | [1] KYUNG J KWON-CHUNG J A S.
