The conversion of 5-hydroxyflavone by various microorganisms was studied. Among them, Streptomyces fulvissimus was the sole microbe which produced a new polar metabolite from 5-hydroxyflavone in addition to 5,4-dihydoxy- and 5,3,4-trihydroxyflavone. The structure of this polar metabolite was determined to

Potential energy (PE) curves for the intramolecular proton transfer in the ground (GSIPT) and excited (ESIPT) states of 3-hydroxy-flavone (3HF) and 5-hydroxy-flavone (5HF) were studied using DFT/B3LYP (6-31G (d,p)) and TD-DFT/B3LYP (6-31G (d,p)) level of theory respectively. Our calculations suggest

In a recent study of the collision-induced dissociation of protonated and deprotonated molecules of 3-, 5-, 6-, 7-, 2'-, 3'- and 4'-hydroxyflavone, it was observed that the ratio, gamma, of the propensities for cross-ring cleavage (CRC) to ring opening (RO)

5,7-Dihydroxyflavone (chrysin) (1) when fermented with fungal cultures, Aspergillus alliaceous (ATCC 10060), Beauveria bassiana (ATCC 13144) and Absidia glauco (ATCC 22752) gave mainly 4'-hydroxychrysin (4), chrysin 7-O-beta-D-4-O-methylglucopyranoside (5) and chrysin 7-sulfate (6), respectively. Mucore ramannianus (ATCC 9628), however, transformed chrysin

The structural changes occurring with the chelation of lead(II) to 3-hydroxyflavone, 5-hydroxyflavone, and 3',4'-dihydroxyflavone have been investigated by the density functional theory (DFT) method with the B3LYP functional and the 6-31G(d,p) basis set. The two effective core potentials Lanl2dz (Los
