  also is a potent phytotoxin. Six 7,8‐benzoflavones and eight 5,6‐benzoflavones were synthesized in this study. The NMR data for a few of these compounds have been previously reported; however, the NMR data for most of them have not been reported. For reference purposes, the complete NMR data for the 14 benzoflavones are described. Copyright © 2012 John Wiley & Sons, Ltd.

  Naphthoflavones (benzoflavones) are synthetic flavonoids commonly used in drug metabolism studies as selective activators or inhibitors of cytochrome P-450 enzymes. Nowadays they are also used as a component of food supplements for body builders. There is no data regarding naphthoflavone microbial metabolism. In the present studies sixty-three fungal strains have been screened for their ability to transform alpha-naphthoflavone (7,8-benzoflavone) or beta-naphthoflavone (5,6-benzoflavone). Five strains belonging to the genera Penicillium, Cladosporium, Aspergillus and Verticillium transformed alpha-naphthoflavone and beta-naphthoflavone to the corresponding 4'-hydroxy derivatives. These selected fungi have been used in a further study on biotransformation of naphthoflavones with a differently substituted B-ring. Only 4'-methoxy derivatives have been transformed to the related 4'-hydroxy products. Selected strains are good biocatalysts to obtain 4'-hydroxy naphthoflavones in the one step reaction.

• β-Naphthoflavone analogs as potent and soluble aryl hydrocarbon receptor agonists: Improvement of solubility by disruption of molecular planarity

  The physiological role of aryl hydrocarbon receptor (AhR) is not yet fully understood, and investigation is hampered by the limited solubility of reported AhR ligands in aqueous media. To achieve improved solubility, we focused on our previous finding that planarity-disruption of molecules leads to less efficient crystal packing and greater aqueous solubility. Here, we describe chemical modification of an AhR agonist, beta-naphthoflavone, focusing on planarity-disruption. As expected, introduction of substituents at the ortho-positions of the phenyl group resulted in greater solubility. Among the compounds prepared, the fluoro analog showed more potent AhR agonistic activity and greater solubility than did b-naphthoflavone. Our results indicate that this strategy to improve aqueous solubility, that is, introduction of substituent(s) that disrupt planarity, may be generally applicable to bicyclic molecules.
