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).

Bacterial colonization of the denuded bone in bisphosphonate-related osteonecrosis of the jaw suggests that bisphosphonates increase bacterial adhesion and biofilm formation. This study evaluated the adhesion of gram-positive and gram-negative bacteria on hydroxyapatite coated with pamidronate, one of the most

Tight regulation of calcium levels is required for many critical biological functions. The Ca2+-sensing receptor (CaSR) expressed by parathyroid cells controls blood calcium concentration by regulating parathyroid hormone (PTH) secretion. However, CaSR is also expressed in other organs, such as
