4-Chromanone has been used to study the substrate specificity and catalytic ability of 4-hydroxyacetophenone monooxygenase isolated from Pseudomonasfluorescens ACB[1].
A new series of tacrine-coumarin hybrids linked to 1,2,3-triazole were designed, synthesized, and tested as potent dual binding site cholinesterase inhibitors (ChEIs) for the treatment of Alzheimer's disease (AD). Among them, compound 8e was the most potent anti-AChE derivative (IC50 = 27 nM)
The aim of this study was to examine the anabolic and anticatabolic functions of bavachin in primary rat chondrocytes. With bavachin treatment, chondrocytes survived for 21 d without cell proliferation, and the proteoglycan content and extracellular matrix increased. Short-term monolayer culture
A number of unsubstituted aromatic hydrocarbons, azaheterocycles, oxaheterocycles and cyclic ketones were screened for their inhibitory potency towards monoamine oxidases (MAO; EC 1.4.3.4.) A and B. Fair activities (IC50 10-100 microM) and selectivities were found for, e.g. naphthalene, anthracene, phenanthrene

Microbial transformation of chromone, chromanone, and 3 ring A hydroxyflavones (5-hydroxy-, 6-hydroxy-, and 7-hydroxyflavones) was attempted using thirty-two microorganisms. While chromone was not biotransformed, chromanone was transformed to chromone and chromanol by Aspergillus niger in 2% yield. Ring A hydroxylated

Alanine-scanning mutagenesis was performed on amino acid residues 210-216 of cytochrome P450 3A4, the major drug-metabolizing enzyme of human liver. Mutagenesis of this region, which has been proposed to align with the C-terminal ends of F-helices from cytochromes P450BM-3, P450terp
