(-)-DHMEQ

CAS No. : 287194-40-5

MCE 国际站：(-)-DHMEQ

产品活性：(-)-DHMEQ (Dehydroxymethylepoxyquinomicin) 是一种有效，选择性且不可逆的 NF-κB 抑制剂，与半胱氨酸残基共价结合。(-)-DHMEQ 抑制 NF-κB 的核易位，并显示抗炎和抗癌活性。

研究领域：NF-κB

作用靶点：NF-κB

In Vitro: (-)-DHMEQ (Dehydroxymethylepoxyquinomicin; 2-10 μg/mL; 12-48 hours) treatment significantly reduces the viability of all cell lines in a dose- and time-dependent manner, whereas the effect is not significant in a control cell line K562 without constitutive NF-κB activity.
(-)-DHMEQ (10 μg/mL; 0-48 hours; TL-Om1, MT-1 and K562 cells) treatment significantly increases the Annexin V-positive cells in MT-1 and TL-Om1 cell lines.
(-)-DHMEQ (10 μg/mL; 4-16 hours; MT-1 cells) treatment down-regulates Bcl-xL, Bcl-2, c-myc, cyclin D1, Rb, and p53, and up-regulates proapoptotic genes such as caspase-3, -8, and-9.
(-)-DHMEQ treatment increases cells in G0 /G1 phase in a time-dependent manner, demonstrating antiproliferative effects of (-)-DHMEQ.
(-)-DHMEQ binds to p65, cRel, RelB, and p50, but not to p52 at specific cysteine residues. (-)-DHMEQ inhibits not only DNA-binding of RelB, but also its interaction to importin. (-)-DHMEQ also induces instability of RelB.

In Vivo: (-)-DHMEQ (Dehydroxymethylepoxyquinomicin; 4 mg/kg or 12 mg/kg; intraperitoneal injection; on day 0 and 3 times a week; for one month; SCID mice) treatment shows a significant increase in the survival rate in mice.
