Eurycomanone stimulates bone mineralization in zebrafish larvae and promotes osteogenic differentiation of mesenchymal stem cells by upregulating AKT/GSK-3β/β-catenin signaling.

Background: Eurycomanone (EN) is a diterpenoid compound isolated from the roots of (). Previous studies have confirmed that can enhance bone regeneration and bone strength. We previously isolated and identified ten quassinoids from , and the result displayed that five aqueous extracts have the effects on promotion of bone formation, among whom EN showed the strongest activity.
