Safety Data Sheet (SDS):
Biological target: Gliotoxin inhibits inducible NF-κB activity by preventing IκB degradation, which consequently induces host-cell apoptosis.
In vitro activity: Consistent with the literature, treatment with higher concentrations of GTX (gliotoxin) at 100 nM and 1 μM caused apoptosis and death of primary CD4+ and CD8+ T cells as well as B cells, natural killer (NK) cells, and monocytes, as shown by annexin V staining followed by flow cytometry (Figs. 2, D and E, and 3C and figs. S3B and S4, A to C). Reference: Sci Adv. 2020 Aug 12;6(33):eaba6617. https://pubmed.ncbi.nlm.nih.gov/32851167/
In vivo activity: The effect of GTX (gliotoxin) in the CNS was evaluated in lumbar spinal cord samples, seven days after its third dose, in both normal and EAE mice. No inflammation or demyelination was observed in normal mice, as illustrated in Figure 3(A1,B1). However, GTX caused inflammation (Figure 3(A2)) and demyelination (Figure 3(B2)) in this group. As expected, a clear process of inflammation (Figure 3(A3)) and demyelination (Figure 3(B3)) was present in the EAE mice. GTX inoculation in EAE mice resulted in a much more pronounced cell infiltration in the meningeal compartment and cortex (Figure 3(A4)), and demyelination (Figure 3(B4)).
