ICEBERG Inhibitors

Chemical inhibitors of ICEBERG act by indirectly affecting the protein's role in inflammatory processes, particularly through the NF-κB signaling pathway and the regulation of inflammasome activity. VX-765 and YVAD-cmk are examples that target the upstream caspase-1, which is crucial for the cleavage of pro-inflammatory cytokines such as IL-1β that ICEBERG helps regulate. By inhibiting caspase-1, these chemicals prevent the activation of the inflammasome, thus indirectly inhibiting the functional role of ICEBERG in the maturation and release of these cytokines. Parthenolide, Bay 11-7082, PDTC, MG-132, QNZ, Wedelolactone, Andrographolide, TPCA-1, BMS-345541, and Sulforaphane constitute a group of chemicals that disrupt the NF-κB pathway at different junctures, which is integral to the expression of pro-inflammatory genes. By doing so, they modulate the activity of ICEBERG within the larger context of its role in immune response.

The specific mechanisms by which these chemicals act on the NF-κB pathway include the inhibition of IκBα phosphorylation (Bay 11-7082), proteasome activity (MG-132), nuclear translocation of NF-κB (QNZ), and IKK complex activity (Wedelolactone, TPCA-1, BMS-345541). Andrographolide and Sulforaphane exert their effects by directly inhibiting the activation of NF-κB. These inhibitors work at different stages of the NF-κB signaling cascade to ensure that the transcriptional activity of NF-κB is suppressed. Since ICEBERG is implicated in the regulation of this pathway, the inhibition of NF-κB by these chemicals results in a decrease in the pro-inflammatory activity that ICEBERG is associated with, thereby functionally inhibiting its role in the immune response.
