Thonzonium bromide is an antibacterial and monocationic surface-active agent. It inhibits RANKL-induced osteoclast formation and bone resorption in vitro, preventing LPS-induced bone loss in vivo. It also inhibits proton transport in a dose-dependent manner, blocking the activation of NF-κB, ERK, and c-Fos, and the induction of NFATc1. This compound disrupts F-actin ring formation in mature osteoclasts, and has shown protective effects in a murine model of LPS-induced calvarial osteolysis.
