A central part (amino-acid position 268-397 of 458 amino-acid residues) of the biphenyl dioxygenase large (alpha) subunit, BphA1, from Pseudomonas pseudoalcaligenes strain KF707 was exchanged with the corresponding part of BphA1 from another biphenyl-degrading bacterium, Pseudomonas putida strain KF715, to

Four flavones (flavone, 7-hydroxyflavone, chrysin, and baicalein) sharing the same B- and C-ring structure but a different numbers of hydroxyl groups on the A-ring were studied for their affinities for BSA and HSA. The hydroxylation on ring A of flavones

Previous studies have shown chrysin, 7-hydroxyflavone and 7,4'-dihydroxyflavone to be the most potent flavonoid inhibitors of aromatase. However, very poor oral bioavailability is a major limitation for the successful use of dietary flavonoids as chemopreventive agents. We have recently shown

A series of 4-aryl substituted 7-hydroxy-flavones were prepared using the three-step Baker-Venkataraman synthesis in good overall yields. The flavones were all evaluated in vitro for inhibitory activity against aromatase (P450AROM, CYP19), using human placental microsomes, and for inhibitory activity against

In a screening programme for inhibitors of human testis 17beta-hydroxysteroid dehydrogenase (17beta-HSD type 3), as potential agents for the treatment of hormone-dependent prostatic cancer, we have used crude human testis microsomal 17beta-hydroxysteroid dehydrogenase as a convenient source of the enzyme.
