Biochem/physiol Actions

Pamidronate disodium has the ability to block Wnt and β-catenin signaling, which modulates the osteogenic differentiation in bone marrow mesenchymal stem cells (BMMSCs). It can also reduce bilirubin-impaired apoptosis and helps to develop dentinogenic dysfunction of stem cells from human deciduous teeth.
Bone resorption inhibitor; inhibitor of farnesyl diphosphate synthase (IC50 = 200 nM).
