Rutaecarpine is a major alkaloid isolated from Evodia rutaecarpa. Here, we investigated the effects of rutaecarpine on osteoclast differentiation induced by macrophage colony stimulating factor (M-CSF) and receptor activator of nuclear factor κ-B ligand (RANKL) in bone marrow-derived macrophages (BMMs). Treatment with rutaecarpine significantly inhibited osteoclastogenesis and prevented bone resorption of BMM-derived osteoclasts. Mechanistically, rutaecarpine decreased the protein level of nuclear factor of activated T cells cytoplasmic-1 (NFATc1) and the phosphorylation of other signalling pathways during the osteoclast differentiation. Thus, rutaecarpine may be useful as a therapeutic agent for the treatment of bone diseases.
