生化/生理作用
脱甲氧基姜黄素 (DMC) 是一种衍生物或姜黄素，是从 姜黄中分离得到的姜黄素产品的主要活性成分之一。DMC通过阻止NF-kB激活来抑制LPS诱导的一氧化氮（NO）产生以及RAW264.7细胞中iNOS和COX2的表达。在LPS处理的大鼠小胶质细胞中，DMC也抑制NF-kB对iNOS，TNFα和IL-1β的表达。DMC通过抑制NF-kB抑制MDA-MB-231人乳腺癌细胞中MMP和ICAM-1的表达。

Reactions of reactive oxygen species (ROS) with curcumin analogues: Structure-activity relationship.
Umang Singh et al.
Free radical research, 45(3), 317-325 (2010-11-03)
Three curcumin analogues viz., bisdemethoxy curcumin, monodemethoxy curcumin, and dimethoxycurcumin that differ at the phenolic substitution were synthesized. These compounds have been subjected for free radical reactions with DPPH radicals, superoxide radicals (O(2)(•-)), singlet oxygen ((1)O(2)) and peroxyl radicals (CCl(3)O(2)(•))
