Chemical Properties
Yellow crystalline powder, soluble in organic solvents such as methanol, ethanol, and DMSO, derived from turmeric rhizomes.
Uses
Demethoxycurcumin (DMC) is a natural demethoxy derivative of curcumin. More stable than curcumin in physiological media, DMC suppresses proliferation in cancer cells at 50-100 μM. It down-regulates the transcriptional coactivator p300, suppressing the Wnt/β-catenin pathway, and inhibits lipopolysaccharide induction of iNOS.
Uses
The demethoxy derivative of Curcumin (C838500) that regulates anti-inflammatory and anti-proliferative responses through a ROS-independent mechanism. It attenuates the Wnt/β-catenin pathway through do
wn-regulation of the transcriptional coactivator p300.
Definition
ChEBI: Demethoxycurcumin is a beta-diketone that is curcumin in which one of the methoxy groups is replaced by hydrogen. It is found in Curcuma zedoaria and Etlingera elatior. It has a role as a metabolite, an antineoplastic agent and an anti-inflammatory agent. It is a polyphenol, a beta-diketone, an enone and a diarylheptanoid.

Biochem/physiol Actions
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.
in vivo
Demethoxycurcumin (3-30 mg/kg/day for 5 days or 20 days, i.p.) regulates the expression of inflammatory and apoptotic genes in the hippocampus and frontal cortex of rat models infused with Aβ + Ibotenic acid (HY-N2311) and helps to improve Alzheimer's disease[3].
Demethoxycurcumin (10 mg/kg/day for 28 days, p.o.) can enhance cognition and enhance choline acetyltransferase (ChAT) activity in mice induced by Scopolamine (HY-N0296) [4].
| Animal Model: | Male ICR mice (6 weeks old) weighing 30–35 g, memory impairment induced by Scopolamine[5] |
| Dosage: | 10 mg/kg/day for 28 days |
| Administration: | Oral gavage (p.o.) |
| Result: | Significantly improved scopolamine induced passive avoidance task learning disabilities and memory impairments in Morris Water Maze.
The activity of choline acetyltransferase (ChAT) was significantly increased to 33.03%.
