Target

RelA

RelB

In Vitro (–)-DHMEQ binds to cysteine 38 of RelA and cysteine 144 of RelB. (−)-DHMEQ at concentrations greater than 25 µM inhibits the LTβ-induced nuclear translocation of FLAG-RelB WT, whereas the inhibitory effect of (–)-DHMEQ on the nuclear translocation of FLAG-RelB (C144S) became weaker at the same concentrations[1].
Cell Assay A549 cells transfectants stably expressing RelB WT and RelB (C144S) are preincubated with various concentrations of (-)-DHMEQ (1, 5, 10, 25, and 50 μM) for 1h and then incubated with or without LTβ (25 ng/mL) for 2 h in the presence or absence of (-)-DHMEQ.Cytoplasmic and nuclear extracts are analyzed by Western blotting[1].
