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.

MEPE is a a member of the SIBLING (Small Integrin-Binding Ligand, N-linked Glycoprotein) family of secreted glycophosphoproteins.? MEPE ?regulates bone mass and influence osteoblast activity.[1].Dentonin (3-30 μg/ml; 2-24 hours) significantly increases the numbers of cell and shows enhanced promotion of cell adhesion. However, it has no significant differences in terms of numbers of cells adhered[2].Dentonin (3-30 μg/ml; 2-24 hours) enhances osteoblast spreading, it exhibits significantly increased cell areas compared to all other treatment[2].
