IKKβ 60 nM (IC50) |
MLB120B (0-20 μM; 90 minutes) inhibits phosphorylation and degradation of IκB in RPMI 8226 and INA6 cells; however, no significant inhibition is observed in MM.1S cells[1].MLB120B (1.25-20 μM; 90 minutes) completely abrogates TNF-a-induced phosphorylation and degradation of IκB in a dosedependent fashion. Phosphorylation of p65 NF-κB induced by TNF-a is also blocked by MLN120B[1].MLN120B inhibits proliferation of multiple myeloma cell lines. MM.1S, MM.1R, RPMI 8226, RPMI-LR5, RPMI-Dox40, U266, and INA6 cells. Five percent to fifty percent and 18% to 70% inhibition in proliferation is observed at doses >20 uM and [3H]thymidine uptake, respectively[1].MLN120B (1.25-40 μM; 72 hours) almost completely blocks stimulation of MM.1S, U266, and INA6 cell growth, as well as IL-6 secretion from BMSCs, induced by multiple myeloma cell adherence to BMSCs[1].MLN120B shows an inhibitory effect on LPS induced NF-κB activation in RAW267.4 cells. The IC50 values of MLN120B is 1.4 μM, 14.8 μM or 27.3 μM for NF-κB2-luc2, IL8-luc2 or TNF-AIP3-luc2 reporter transfected cells, respectively[3].
