Ações bioquímicas/fisiológicas

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.

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

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)(•))
