Dentonin (AC-100) is a synthetic fragment derived from MEPE that enhances osteogenesis by promoting osteoprogenitor adhesion and facilitating the survival of immature adherent cells. It does not have a significant effect on mature osteoblasts. Dentonin is useful for research on phosphate homeostasis and bone metabolism.

Fz7-21 ((Ac)-LPSDDLEFWCHVMY-NH2) is a peptide antagonist of FZD7 . It antagonises WNT3A-induced Wnt-β-catenin signalling in HEK293 expressing FZD7. Fz7-21 impairs Wnt/β-catenin signaling in HEK293 cells stimulated with exogenous WNT3A (IC50=100 nM) or transfected with a construct expressing WNT3A or WNT1. Fz7-21 also blocks WNT3A-mediated stabilization of β-catenin in mouse L cells (IC50=50 nM).
