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 ...

Toxicity Assessments of Chalcone and Some Synthetic Chalcone Analogues in a Zebrafish Model [PDF]
Molecules, 2014 The aim of this study was to investigate the in vivo toxicities of some novel synthetic chalcones. Chalcone and four chalcone analogues 1a–d were evaluated using zebrafish embryos following antibody staining to visualize their morphological changes and ...

Abstract 2′-hydroxychalcone dibromides substituted by OMe in the 6′-position are found to yield little or no aurone in dilute aqueous ethanolic potassium hydroxide. The proportion of aurone to flavone in their products parallels increasing hydroxide concentration.

Chemical sensing of chalcones by voltammetry: trans-Chalcone, cardamonin and xanthohumol
Electrochimica Acta, 2013Abstract Xanthohumol (XN) and cardamonin (CD) belong to the chemical class of chalcones which are phenolic compounds of large interest due to their health promoting properties. In the present work, their electrochemical behavior on a hanging mercury drop electrode (HMDE) is compared to trans -chalcone by means of cyclic voltammetry (CV).

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.

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 ...
