生物活性:
Zoledronic Acid (Zoledronate) disodium tetrahydrate is a third-generation bisphosphonate (BP), with potent anti-resorptive activity. Zoledronic Acid disodium tetrahydrate inhibits the differentiation and apoptosis of osteoclasts. Zoledronic Acid disodium tetrahydrate also has anti-cancer effects.

体内研究:
Zoledronic Acid disodium tetrahydrate (0.05 mg/kg; i.p.; weekly; for 3 weeks) increases bone mineral density and content.Zoledronic Acid disodium tetrahydrate (0.5-1 mg/kg; i.p.; weekly; for 3 weeks) inhibits both osteoclast and osteoblasts function and bone remodeling in vivo interfering with bone mechanical properties.Animal Model:Five-week-old C57BL6 mice
Dosage:0.05 mg/kg, 0.5 mg/kg, 1 mg/kg
Administration:Intraperitoneal injection, weekly, for 3 weeks
Result:Inhibited both osteoclast and osteoblasts function and bone remodeling at 0.5 mg/kg and 1 mg/kg.

体外研究:
Zoledronic Acid disodium tetrahydrate (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.Zoledronic Acid disodium tetrahydrate increases the expression of osteoclastogenesis supporting factor from MLO-Y4 cells.Zoledronic Acid disodium tetrahydrate enhances the RANKL expression via IL-6/ JAK2/STAT3 pathway in MLO-Y4 cells.Zoledronic acid disodium tetrahydrate inhibits osteoclast differentiation and function through the regulation of NF-κB and JNK signalling pathways.Zoledronic Acid disodium tetrahydrate (10-100 μM; 1-7 days) markedly reduces the viability of MC3T3-E1 cells and induces apoptosis in MC3T3-E1 cells.Zoledronic Acid disodium tetrahydrate (10-100 μM; 4 days) inhibits cell viability due to the induction of apoptosis.Zoledronic Acid disodium tetrahydrate exerts inhibitory effects on the differentiation and maturation of MC3T3-E1 cells at concentrations Zoledronic acid disodium tetrahydrate 相关抗体:Cell Viability AssayCell Line:MC3T3-E1 cells
