ABSTRACT
Since elevated osteoclast formation and/or activity by inhibitory responses against pathogens leads to diverse osteolytic bone diseases including periodontitis, inhibition of osteoclast differentiation and bone resorption has been a primary therapeutic strategy. In this study, we investigated the therapeutic potential of a novel benzamide-linked molecule, OCLI-070, for preventing alveolar bone loss in mice with ligature-induced experimental periodontitis. OCLI-070 inhibited osteoclast formation by acting on both early and late stages of differentiation, and attenuated the induction of nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1) and the expression of osteoclast-specific genes. In addition, OCLI-070 significantly suppressed the formation of actin rings and resorption pits. Analysis of the inhibitory action of OCLI-070 showed that it markedly suppressed receptor activator of nuclear factor-κB ligand (RANKL)-induced extracellular signal-regulated kinase (ERK) and NF-κB signaling cascades. Moreover, OCLI-070 prevented ligature-induced alveolar bone erosion in mice by suppressing osteoclast formation. These findings demonstrate that OCLI-070 attenuated osteoclast differentiation and function as well as ligature-induced bone erosion by inhibiting RANKL-mediated ERK and NF-κB signaling pathways.
