Bisdemethoxycurcumin >98%
Odor: characteristic
Use: Bisdemethoxycurcumin is one of the three major forms of curcuminoids found in the rhizomes of turmeric. Bisdemethoxycurcumin displays antioxidant, anti-inflammatory as well as chemotherapeutic activity.
For experimental / research use only.
Bisdemethoxycurcumin from Plants ≥98%
Odor: characteristic
Use: Antiedemic, anti-inflammatory agent. Bile stimulant showing hepatoprotective props. Possesses bactericidal and fungicidal props. Antitumour agent functioning through apoptosis. Nutriceutical. Shows antioxidant activity. 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.
