  Synthesis of biflavones having a 6-O-7’’ linkage and effects on cyclooxygenase-2 and inducible nitric oxide synthase

  摘要：

  In order to establish anti-inflammatory potential of biflavonoids, 17 biflavone derivatives having a 6-O-7 '' linkage were synthesized and their effects on cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) were evaluated. The basic molecule (6-O-7 '' biflavone) potently inhibited COX-2-mediated PGE(2) production (IC50: < 2 mu M), being less active on iNOS-mediated NO production (IC50: > 50 mu M) from lipopolysaccharide-treated RAW 264.7 cells, a mouse macrophage cell line. Generally, the hydroxyl/methoxyl substitution(s) on the basic biflavone (6-O-7 '') reduced the inhibitory activity of PGE(2) production, while the effects on NO production were varied. It is suggested that the basic biflavone (6-O-7 '') may have a potential for new anti-inflammatory agent. (C) 2008 Elsevier Ltd. All rights reserved.
