lps-induced bone resorption

(-)-Epigallocatechin Gallate (EGCG) is a phenolic antioxidant polyphenol flavonoid found in plants such as green and black tea, which inhibits telomerase and DNA methyltransferase, blocks the activation of EGF receptors and HER-2 receptors, inhibits cellular oxidation, and prevents free radical damage to cells.

Thonzonium bromide is a mono-cationic surfactant that is structurally similar to Farnesol as an antimicrobial agent. It inhibits proton transport in a dose-dependent manner (EC50=69 μM). It inhibits RANKL-induced osteoclast formation and bone resorption in vitro and prevents LPS-induced bone loss in vivo.
