Biological Activity for BMS 345541

BMS 345541 is a selective allosteric inhibitor of IKK (IC50 values are 0.3 and 4.0 μM for IKKβ and IKKα respectively). Exhibits no effect against a panel of 15 other kinases. Attenuates LPS-induced cytokine production in vitro and blocks NFκB dependent transcription in mice. Also suppresses joint destruction in a mouse model of arthritis.

BMS 345541 (Cat. No. 4806) in 3 D cultures.
By Clara Lubeseder-Martellato on 11/12/2021
Assay Type: Ex Vivo
Species: Mouse
Cell Line/Tissue: Acini

BMS 345541 was added to pancreatic acinar 3-dimensional cultures and differentiation of the cultures was monitored for 3 to 4 days. The concentration ranged between 1 and 10 uM.

Great, easy to store.
By Brian Englar on 02/06/2019
Assay Type: Ex Vivo
Species: Human
Cell Line/Tissue: MDA-231

This IKK inhibitor worked in our evaluation of TAK1 in MDA-231 cells. We compared the ability of this inhibitor to induce TNf mediated death to a TAK1 inhibitor.
