On the basis of our recent findings that licochalcone A isolated from Xin-jiang licorice showed anti-inflammatory and anti-tumorigenic activities, we synthesized more than 40 chalcone derivatives to examine their anti-tumorigenic activities. In vitro inhibitory activity against phosphorylation of phospholipids promoted by tetradecanoylphorbol-13 ...

Stereoselectivity of chalcone isomerase with chalcone derivatives: a computational study
Journal of Molecular Modeling, 2013Chalcone isomerase (CHI) catalyzes the intramolecular cyclization of chalcones into flavonoids. The activity of CHI is essential for the biosynthesis of flavonoids precursors of floral pigments and phenylpropanoid plant defense compounds. In the present study, we explored the detailed binding structures and binding free energies for two different ...

Coupling–Isomerization Synthesis of Chalcones
Chemistry – A European Journal, 2006AbstractThe Sonogashira coupling of electron‐deficient (hetero)aryl halides 1 and (hetero)aryl or alkenyl 1‐propargyl alcohols 2 does not terminate at the stage of the expected internal propargyl alcohols, but rather gives rise to the formation of α,β‐unsaturated ketones 3 with a variety of acceptor substituents.

Expression of chalcone synthase and chalcone isomerase proteins in Arabidopsis seedlings
Plant Molecular Biology, 1997Antibodies have been developed against the first two enzymes of flavonoid biosynthesis in Arabidopsis thaliana. Chalcone synthase (CHS) and chalcone isomerase (CHI) were overexpressed and purified from Escherichia coli as fusion proteins with glutathione S-transferase from Schistosoma japonicum.

Chalcones XVI: infrared spectral studies of phenanthryl chalcones
Monatshefte f�r Chemie, 1977IR absorption spectra of ten phenanthryl chalcones have been studied with a view to see the effect on stretching frequencies of α, β-unsaturated carbonyl group when conjugated to the phenanthryl nucleus.
