Trans-chalcone is the precursor molecule to flavonoids and possesses antioxidant and anti-inflammatory properties. This study aimed to evaluate the effects of trans-chalcone on atheroma plaque formation and the relevant biochemical parameters in high cholesterol diet (HCD)-fed NMRI mice.Fifty male NMRI mice were divided into 5 groups (n=10 per group ...

Asymmetric Epoxidation of trans‐Chalcones Organocatalyzed by β‐Amino Alcohols
European Journal of Organic Chemistry, 2008AbstractCyclic and acyclic β‐amino alcohols were examined as organocatalysts in the epoxidation of trans‐chalcones with tert‐butyl hydroperoxide as the oxidant. Primary, secondary, and tertiary β‐amino alcohols are able to promote the reaction with variable activity and level of asymmetric induction.

The interaction between the network of chemical reactions of the compound 4',7-dihydroxyflavylium and β-cyclodextrin was studied by means of pH jumps, followed by UV-vis absorption, flash photolysis, stopped flow, and NMR. The trans-chalcone is the network species exhibiting the strongest interaction with the host.
