  Treatment of Sepsis Pathogenesis with High Mobility Group Box Protein 1-Regulating Anti-inflammatory Agents

  摘要：

  Sepsis is one of the major causes of death worldwide when associated with multiple organ failure. However, there is a critical lack of adequate sepsis therapies because of its diverse patterns of pathogenesis. The pro-inflammatory cytokine cascade mediates sepsis pathogenesis, and high mobility group box proteins (HMGBs) play an important role as late-stage cytokines. We previously reported the small-molecule modulator, inflachromene (1d), which inhibits the release of HMGBs and, thereby, reduces the production of pro-inflammatory cytokines. In this context, we intraperitoneally administered Id to a cecal ligation and puncture (CLP)-induced mouse model of sepsis and confirmed that it successfully ameliorated sepsis pathogenesis. On the basis of a structure activity relationship study, we discovered new candidate compounds, 2j and 21, with improved therapeutic efficacy in vivo. Therefore, our study clearly demonstrates that the regulation of HMGB1 release using small molecules is a promising strategy for the treatment of sepsis.

  Discovery of Novel Benzopyranyl Tetracycles that Act as Inhibitors of Osteoclastogenesis Induced by Receptor Activator of NF-κB Ligand

  摘要：

  A novel benzopyran-fused molecular framework 7ai was discovered as a specific inhibitor of RANKL-induced osteoclastogenesis using a cell-based TRAP activity assay from drug-like small-molecule libraries constructed by diversity-oriented synthesis. Its inhibitory activity was confirmed by in vitro evaluations including specific inhibition of RANKL-induced ERK phosphorylation and NF-kappa B transcriptional activation. 7ai can serve as a specific small-molecule modulator for mechanistic studies of RANKL-induced osteoclast differentiation as well as a potential lead for the development of antiresorptive drugs.
