287194-40-5 用途與合成方法

(-)-DHMEQ (Dehydroxymethylepoxyquinomicin) 是一種有效,選擇性且不可逆的 NF-κB 抑制劑,與半胱氨酸殘基共價(jià)結(jié)合。(-)-DHMEQ 抑制 NF-κB 的核易位,并顯示抗炎和抗癌活性。

RelA

RelB

(-)-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.

Cell Proliferation Assay

Cell Line: TL-Om1, MT-1, KK-1, ST-1 and K562 cells
Concentration: 2 μg/mL, 5 μg/mL, 10 μg/mL
Incubation Time: 12 hours, 24 hours, 48 hours
Result: Significantly reduced the viability of all cell lines in a dose- and time-dependent manner.

Apoptosis Analysis

Cell Line: TL-Om1, MT-1 and K562 cells
Concentration: 10 μg/mL
Incubation Time: 0 hours, 24 hours, 48 hours
Result: Annexin V-positive cells were significantly increased after 24 to 48 hours.

Western Blot Analysis

Cell Line: MT-1 cells
Concentration: 10 μg/mL
Incubation Time: 4 hours, 8 hours, 16 hours
Result: Annexin V-positive cells were significantly increased after 24 to 48 hours.

(-)-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.

Animal Model: Male C.B17-scid/scid (5 weeks old) mice injected with MT-2 cells
Dosage: 4 mg/kg or 12 mg/kg
Administration: Intraperitoneal injection; on day 0 and 3 times a week; for one month
Result: Showed a significant increase in the survival rate in mice.
