Interaction of curcumin with Zn(II) and Cu(II) ions based on experiment and theoretical calculation

Curcumin-conjugated magnetic nanoparticles for detecting amyloid plaques in Alzheimer's disease mice using magnetic resonance imaging (MRI)

“…In curcumin conjugated MNPs, however, the peaks at 1628, 1603, 1429 and 1376 cm À1 were diminished, and a strong peak at 1654 cm À1 appeared, representing a conjugated C]O bond [50,61,62]. The OeH peak broadened and shifted to 3422, meaning that more hydroxyl bonds formed in the conjugated product, while the enolic (COH) peaks were not found, consistent with the C]O 1752 cm À1 for PLA, and CeOeC at 1094 cm À1 for PEG.…”

Dual Effect of Curcumin–Zinc Complex in Controlling Diabetes Mellitus in Experimentally Induced Diabetic Rats

“…17) An equimolar mixture of Zn sulfate (10 mmol) in 50 mL absolute ethanol and curcumin extract (10 mmol) in 50 mL absolute ethanol separately were mixed and few drops of triethylamine were added. The mixture was heated under reflux at 60°C for 2 h with simultaneous stirring.…”

Facile synthesis of Curcuma longa tuber powder engineered metal nanoparticles for bioimaging applications

“…Much research has demonstrated that C. longa tuber powder has natural fluorescence due to the presence of curcumin, some studies have been carried out to investigate the interaction between metals and curcumin [21][22][23] to show that the curcumin keto and enol group oxygen lone pairs interact with acceptor orbital of metal ions, and may act as a strong reducing, encapsulating and stabilizing agent for the formation of fluorescent metal nanoparticles (Fig. 1).…”
