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.
Disclosed herein is an anti-inflammatory pharmaceutical composition comprising a benzopyranyl tetracycle compound represented by Chemical Formula 1 as an active ingredient. The compound exhibits excellent anti-inflammatory activity by perturbing the post-translational modification of the inflammation mediator HMGB, and thus finds applications in pharmaceutical compositions superior in the treatment or prevention of inflammation-related diseases.
