Biochem/physiol Actions
Bisdemethoxycurcumin (BDMC) is a derivative or curcumin, and represents one of the major active components of curcumin products isolated from Curcumae sp. BDMC shares similar anti-inflammatory properties with demethoxycurcumin. It inhibits LPS-induced nitric oxide (NO) production and expression of iNOS and COX2 in RAW264.7 cells by blocking NF-kB activation. BDMC also displays unique properties in that it enhances Abeta clearance by upregulating expression MGAT3 and TLR genes. BDMC potently inhibits AKR1B10.
