Dimethyl fumarate (Synonyms: 富馬酸二甲酯)
Dimethyl fumarate (DMF) 是一種具有口服活性且可透過血腦屏障的 Nrf2 激huo劑，可誘導抗氧化劑基因表達上調。Dimethyl fumarate 通過 GSH 耗竭/ROS 升高/MAPKs 激huo途徑誘導結腸癌細胞壞死，并誘導細胞自噬 (autophagy)。Dimethyl fumarate 可用于多發性硬化癥的研究。
生物活性
Dimethyl fumarate (DMF) is an orally active and brain-penetrant Nrf2 activator and induces upregulation of antioxidant gene expression. Dimethyl fumarate induces necroptosis in colon cancer cells through GSH depletion/ROS increase/MAPKs activation pathway, and also induces cell autophagy. Dimethyl fumarate can be used for multiple sclerosis research

體外研究(In Vitro)
Dimethyl fumarate (DMF; 20-200?μM; 24 hours) treatment dose-dependently reduces the viability of SGC-7901, HT29, HCT116 and CT26 cancer cells[1].
Dimethyl fumarate (DMF; 100?μM; 3-24 hours) significantly activates JNK, p38 and ERK in CT26 cells[1].
Dimethyl fumarate induces necroptosis in colon cancer cells and the mechanism involves GSH depletion, an increase in ROS and activation of MAPKs-mediated signalling[1].
Dimethyl fumarate inhibits dendritic cell (DC) maturation by reducing inflammatory cytokine production (IL-12 and IL-6) and the expression of MHC class II, CD80, and CD86. Dimethyl fumarate impairs NF-κB signaling via reduced p65 nuclear translocalization and phosphorylation. Dimethyl fumarate inhibits maturation of DCs and subsequently Th1 and Th17 cell differentiation by suppression of both NF-κB and ERK1/2-MSK1 signaling[2].
