One new curcuminoid, 3'-demethoxycyclocurcumin (1), was isolated from Curcuma xanthorrhiza as an antibabesial compound, together with p-hydroxybenzaldehyde (2) and cleomiscosin A (3) from Brucea javanica and (+)-epiloliolide (4) from Excoecaria cochinchinensis. The antibabesial activities were examined in vitro, and compounds 1-4, and diminazene aceturate were studied with IC(50) values of 16.6...

Curcuminoids, natural products in the rhizome of turmeric, show various biological activities, including antioxidant and antitumor activities. For this reason, curcuminoids have been focused on as potential pharmaceuticals. Exogenous supplementation with various carboxylate precursors in genetically engineered Escherichia coli cells carrying an artificially assembled pathway for curcuminoid bio...

BACKGROUND Commercially available curcumin preparations contain a mixture of related polyphenols, collectively referred to as curcuminoids. These encompass the primary component curcumin along with its co-purified derivatives demethoxycurcumin and bisdemethoxycurcumin. Curcuminoids have numerous biological activities, including inhibition of cancer related cell proliferation and reduction of am...
