Title Halenaquinone inhibits RANKL-induced osteoclastogenesis.
Journal Bioorg Med Chem Lett
Abstract Halenaquinone was isolated from the marine sponge Petrosia alfiani as an inhibitor of osteoclastogenic differentiation of murine RAW264 cells. It inhibited the RANKL (receptor activator of nuclear factor-κB ligand)-induced upregulation of TRAP (tartrate-resistant acid phosphatase) activity as well as the formation of multinuclear osteoclasts. In addition, halenaquinone substantially suppressed RANKL-induced IκB degradation and Akt phosphorylation. Thus, these results suggest that halenaquinone inhibits RANKL-induced osteoclastogenesis at least by suppressing the NF-κB and Akt signaling pathways.
