Superior anticancer activity of halogenated chalcones and flavonols over the natural flavonol quercetin

European Journal of Medicinal Chemistry, 2013
A series of chalcone and flavonol derivatives were synthesized in good yield by an eco-friendly approach. A pharmacological evaluation was performed with the human colorectal carcinoma cell line HCT116 and revealed that the anticancer activity of flavonols was higher when compared with that of the respective chalcone precursors.

Changes of flavonol synthase and flavonol contents during grape berry development

European Food Research and Technology, 2013
Flavonols as an important kind of flavonoids not only have many defense-related functions, but also play an important role as potent antioxidants. Flavonol synthase (FLS) as the key enzyme in flavonol synthesis determines the final contents of flavonols in plant materials.

The flavonols of Impatiens balsamina L

Archives of Biochemistry and Biophysics, 1958
Abstract The flavonols, kampherol, quercetin, and probably myricetin, are found in the flowers of Impatiens balsamina L. Kampherol is present in the petals and sepals of all genotypes; quercetin is found in the sepals only, but in all genotypes; and myricetin, found in both petals and sepals, is correlated with the presence of the gene L.

Flavonols drive plant microevolution

Nature Genetics, 2016
The idea that pollinators are in large part responsible for the diversity of flowering plants dates back more than 150 years to Darwin's work, but even modern scientists have struggled to identify specific 'speciation genes' and determine how they influenced flower-pollinator interactions.

Flavonol Regulation in Tumor Cells

Journal of Cellular Biochemistry, 2015
ABSTRACTFlavonols comprise a group of flavonoid molecules that are widely distributes in fruits and vegetables. There is epidemiological data to suggest that consumption of flavonols can be accompanied by decreased cancer incidence. The anti‐oxidant activity of flavonols may have an important role in preventing carcinogenesis.
