Photoreactions of Flavanones [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1976
Abstract On irradiation in benzene, 5,7-dimethyl-4′-methoxyflavanone gave a bis-flavanone V, while in 2-propanol it was largely recovered. Irradiation of 4′-methoxyflavanone in benzene and 2-propanol yielded the corresponding chalcone and pinacols, respectively.

The Nrf2/HO-1 Axis as Targets for Flavanones: Neuroprotection by Pinocembrin, Naringenin, and Eriodictyol

open access: yesOxidative Medicine and Cellular Longevity, 2019
Flavanones are a group of flavonoids that derive from their immediate chalcone precursors through the action of chalcone isomerase enzymes. The Aromatic A and B rings, C4-keto group, and the 15-carbon flavonoid skeleton are all evident in flavanones, but

Synthesis and Stereochemical Characterization of a Novel Chiral α-Tetrazole Binaphthylazepine Organocatalyst

open access: yesMolecules, 2022
A novel α-tetrazole-substituted 1,1′-binaphthylazepine chiral catalyst has been synthesized and its absolute configuration has been determined by DFT computational analysis of the vibrational circular dichroism (VCD) spectrum of its precursor.

Citrus flavanones upregulate thyrotroph Sirt1 and differently affect thyroid Nrf2 expressions in old-aged Wistar rats.

open access: yesJournal of Agricultural and Food Chemistry, 2020
Growing population of elderly consumes citrus flavanones, naringenin and hesperetin, in form of fruits or juices. Flavanones are bioactives with potent antioxidant properties and potential in slowing down the aging process.

Methoxy-Substituted γ-Oxa-ε-Lactones Derived from Flavanones—Comparison of Their Anti-Tumor Activity In Vitro

open access: yesMolecules, 2021
Background: The study investigated four flavanone-derived γ-oxa-ε-lactones: a parent unsubstituted compound and its three derivatives with the methoxy group in positions 2′, 4′ and 8. Our objective was to find out if the introduction of the methoxy group

Dietary flavonoid intake and incidence of erectile dysfunction [PDF]

open access: yes, 2016
Background: The predominant etiology for erectile dysfunction (ED) is vascular, however limited data are available on the role of diet. A higher intake of several flavonoids reduces diabetes and cardiovascular disease (CVD) risk but no studies have ...
