Demethoxycurcumin (DMC) is a derivative or curcumin, and represents one of the major active components of curcumin products isolated from Curcumae sp. DMC inhibits LPS-induced nitric oxide (NO) production, and expression of iNOS and COX2 in RAW264.7 cells by blocking NF-kB activation. DMC also inhibits NF-kB dependent iNOS, TNFα and IL-1β expression in LPS-treated rat microglial cells. DMC suppresses expression of MMPs and ICAM-1 in MDA-MB-231 human breast cancer cells by inhibition of NF-kB.

Matrix metalloproteinase-3 (MMP-3) is a key enzyme with important implications in the invasion and metastasis of breast cancer cells. Curcumin (Cur), demethoxycurcumin (DMC), and bisdemethoxycurcumin (BDMC) are major forms of curcuminoids found in turmeric powder with reported anticancer activity. This
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)(•))

Our previous report has showed that demethoxycurcumin (DMC), a natural derivative of curcumin (Cur), exhibited stronger inhibitory activity on nitric oxide (NO) and tumor necrosis factor-alpha (TNF-alpha) production compared with Cur in lipopolysaccharide (LPS) activated rat primary microglia. In the
Alzheimer's disease (AD) is a neurodegenerative disease. There are a limited number of therapeutic options available for the treatment of AD. Curcuminoids (a mixture of bisdemethoxycurcumin, demethoxycurcumin and curcumin) is the main chemical constituent found in turmeric, a well known

Demethoxycurcumin (DMC) is one of the main active compounds of curcuminoids found in turmeric powder, which is used as a spice in Asian cooking and traditional medicine. Recent studies reveal that DMC has several biological activities including anti-inflammation and anti-cancer
