  Synthesis and biological evaluation of pyranoisoflavone derivatives as anti-inflammatory agents

  摘要：

  In this paper, barbigerone (1a) and its twenty-seven related structural analogues were synthesized via complementary synthetic routes and their anti-inflammatory effects on the expression of TNF-α in LPS-stimulated splenocytes were evaluated. Among these compounds, 1a, 1d, 1f and 1g were found to remarkably inhibit TNF-α production. Furthermore, 1g showed the most potent and dose-dependent manner inhibitory effect on TNF-α release, with better IC50 value (3.58 μM) than barbigerone (8.46 μM). Oral administration of 1g at 20 mg/kg/day for two weeks obviously demonstrated protective effect in adjuvant-induced arthritis models as evaluated by clinical score of paws, and histological examination of joint tissues from rats. Mechanism studies on mRNA and protein level suggested that 1g inhibited the TNF-α production via depressing TNF-α converting enzyme (TACE) mRNA expression. In conclusion, these data show 1g with potential therapeutic effects as an anti-inflammatory agent.

  Synthesis of positional isomers is a commonly used technique in drug design. Accordingly, based on prior SAR studies of 3'R,4'R-di-O-(S)-camphanoyl-(+)-cis-khellactone (DCK, 1) analogues, a series of mono- and disubstituted chromone derivatives of 3'R,4'R-di-O-(-)-camphanoyl-2',2'-dimethyldihydropyrano[2,3-f]chromone (DCP, 4) were designed and synthesized. Together with 1 and 4-methyl DCK (2), all
