BMS-345541 Usage And Synthesis

Uses

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

Biological Activity

bms-345541 is a highly selective inhibitor of ikk-1 and ikk-2 with ic50 values of 4μm and 0.3μm, respectively [1].bms-345541 is a highly selective inhibitor of ikk that inhibits nf-κb-dependent transcription of pro-inflammatory cytokines both in vitro and in vivo. this specificity is proved in the assay measuring the ikk-2-catalyzed phosphorylation of gst-iκb. in this assay, bms-345541 fails to inhibit other serine/threonine and tyrosine kinases. this selectivity is also evident in cells, only the stimulus-induced phosphorylation of iκb was inhibited by bms-345541 whereas other signal transduction cascades were unaffected [1].since the ikk/ nfκb pathway is important for viability of leukemic cells and is a predictor of relapse in t-all, bms-345541 is tested in some t-all cell lines. it is found that bms-345541 can induce apoptosis and an accumulation of cells in the g2/m phase of the cell cycle. bms-345541 can be used in combination with traditional therapies to overcome resistance to chemotherapeutic agents [2].

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.
