Application

BMS-345541 has been used:
  • as an IκB kinase (IKK) complex inhibitor to study its effects on the interferon-γ (IFN-γ) production by natural killer (NK) cells
  • as an IKK inhibitor to study its effects on the expression of eotaxin and monocyte chemoattractant protein-1 (MCP-1) mRNA in gingival fibroblasts
  • as nuclear factor κB (NF-κB) pathway inhibitor to study its effects on tumor necrosis factor α (TNFα) production in human oral squamous carcinoma cells

Biochem/physiol Actions

BMS-345541 possesses anti-inflammatory properties. It also blocks the nuclear factor κB (NF-κB)-dependent transcription of pro-inflammatory cytokines. BMS-345541 possesses anti-inflammatory activity and plays a role in arresting bone erosion in certain animal models.
BMS-345541 is an IKB kinase (IKK) allosteric site inhibitor.
