(-)-DHMEQ is a potent NF-κB inhibitor.
(-)-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 experiment: |
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]. |

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
