IUPAC Name: (3R,5aS,6S,10aR)-6-hydroxy-3-(hydroxymethyl)-2-methyl-2,3,5a,6-tetrahydro-10H-3,10a-epidithiopyrazino[1,2-a]indole-1,4-dione
InChIKey: FIVPIPIDMRVLAY-RBJBARPLSA-N
SMILES: O=C1N([C@]2(C(N3[C@]1(CC4=CC=C[C@@H]([C@@]34[H])O)SS2)=O)CO)C
Biological Activity: Gliotoxin is a secondary metabolite, the most abundant mycotoxin secreted by A. fumigatus, inhibits the phagocytosis of macrophages and the immune functions of other immune cells [1]. Gliotoxin inhibits inducible NF-κB activity by preventing IκB degradation, which consequently induces host-cell apoptosis[2]. Gliotoxin activates PKA and increases intracellular cAMP concentration; modulates actin cytoskeleton rearrangement to facilitate A. fumigatus internalization into lung epithelial cells[3]. Gliotoxin is a potent NOTCH2 transactivation inhibitor, can effectively induce apoptosis of chronic lymphocytic leukemia (CLL) cells[4].
