Stemcell, 73572, Zoledronic Acid

Zoledronic acid is a nitrogen-containing bisphosphonate that inhibits farnesyl diphosphate (FPP) synthase (IC₅₀ = 5 nM), thereby preventing protein prenylation and osteoclast-mediated bone resorption (Dunford et al.). In addition, it has a high affinity for hydroxyapatite (Ki = 3.5 μM) which allows it to bind directly to mineralized bone (Nancollas et al.). This product is supplied as the hydrate form of the molecule.
