demethoxycurcumin

1. Demethoxycurcumin (Desmethoxycurcumin) has antioxidant activity. 2. Demethoxycurcumin has anti-inflammatory activity. 3. Demethoxycurcumin has anti-proliferative activity. 4. Demethoxycurcumin has anti-acanthamoebic effect. 5. Demethoxycurcumin is a potential additive natural product in combination with chemotherapeutic agents in drug-resistant cancers. 6. Demethoxycurcumin inhibits energy metabolic and oncogenic signaling pathways through AMPK activation in triple-negative breast cancer cells.

Demethoxycurcumin is found in Curcuma zedoaria and Etlingera elatior. It has a role as a metabolite, an antineoplastic agent and an anti-inflammatory agent.

Bisdemethoxycurcumin (Curcumin III) is a natural demethoxy derivative of curcumin. It is a potent activator of macrophage phagocytosis, interacting with 1α, 25-dihydroxy vitamin D3 to stimulate amyloid-β clearance by macrophages (optimal stimulation at 100 nM BDMC) [1]. More stable than curcumin in physiological media, BDMC suppresses proliferation of cancer cells [2]. It down-regulates the transcriptional coactivator p300, suppressing the Wnt β-catenin pathway, and inhibits LPS induction of iNOS expression [3].

Di-O-methyldemethoxycurcumin is a Curcumin analog isolated from medicinal plant turmeric di-orthomethyldemethoxycurcumin, anti-inflammatory and antioxidant properties Inhibition of IL-6 production, EC50 is 16.20μg mL.

Cyclobisdemethoxycurcumin exhibits antioxidant properties, demonstrated by its half maximal inhibitory concentrations (IC50s) of approximately 250 μM in the DPPH radical scavenging assay and 15-20 μM in the 2-DR oxidation assay [1].
