Zoledronic acid-d₅  (Synonyms: Zoledronate-d₅; CGP 42446-d₅; CGP42446A-d₅; ZOL 446-d₅)

Zoledronic acid-d₅ is deuterated labeled Zoledronic Acid (HY-13777). Zoledronic Acid (Zoledronate) is a third-generation bisphosphonate (BP), with potent anti-resorptive activity. Zoledronic Acid inhibits the differentiation and apoptosis of osteoclasts. Zoledronic Acid also has anti-cancer effects^[1].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
Zoledronic Acid (0.1-1 μM; 48 hours) increases receptor activator of nuclear factor kB ligand (RANKL) and sclerostin mRNA expressions in osteocyte-like MLO-Y4 cells^[3].
Zoledronic Acid increases the expression of osteoclastogenesis supporting factor from MLO-Y4 cells^[3].
Zoledronic Acid enhances the RANKL expression via IL-6/ JAK2/STAT3 pathway in MLO-Y4 cells^[3].
Zoledronic acid inhibits osteoclast differentiation and function through the regulation of NF-κB and JNK signalling pathways^[4].
Zoledronic Acid (10-100 μM; 1-7 days) markedly reduces the viability of MC3T3-E1 cells^[5].
Zoledronic Acid (10-100 μM; 1-7 days) induces apoptosis in MC3T3-E1 cells^[5].
Zoledronic Acid (10-100 μM; 4 days) inhibits cell viability due to the induction of apoptosis^[5].
Zoledronic Acid exerts inhibitory effects on the differentiation and maturation of MC3T3-E1 cells at concentrations <1 μM^[5].
