  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.

  report a novel strategy for the design and construction of natural and natural product-like libraries based on the principle of privileged structures, a term originally introduced to describe structural motifs capable of interacting with a variety of unrelated molecular targets. The identification of such privileged structures in natural products is discussed, and subsequently the 2,2-dimethylbenzopyran

  24 derivatives (5a–x) derived from natural pyranochalcones (I and II) were designed and evaluated for their inhibitory potency on the production of nitric oxide (NO) in LPS-stimulated RAW264.7 cells. Among them, four compounds (5b, 5d, 5f, and 5h) exhibited more potent inhibitory effects on iNOS activity and iNOS-mediated NO production than a positive control indomethacin. Furthermore, 5b could significantly

  A series of novel STAT3 inhibitors consisting of Michael acceptor has been identified through assays of the focused in-house library. In addition, their mode of action and structural feature responsible for the STAT3 inhibition were investigated. In particular, analog 6 revealed promising STAT3 inhibitory activity in HeLa cell lines. The analog also exhibited selective inhibition of STAT3 phosphorylation without affecting STAT1 phosphorylation and cytostatic effect in human breast epithelial cells (MCF10A-ras), which supports cancer cell-specific inhibitory properties.
