Uses
Zoledronic acid monohydrate is an anti-resorptive agent for cancer bone metasis, also used on studies in the environmental risk asseessment of drugs from view of excretion form to environment.
Uses
A highly potent bisphosphonate and activator of PKC.
brand name
Zometa (Novartis).
General Description
Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards
Biological Activity
Zoledronic acid (Zoledronate, CGP-4244) monohydrate is the monohydrate of Zoledronic acid (Zoledronic acid), a potent osteoclast inhibitor that inhibits small GTP-binding proteins by inhibiting enzymes of the mevalonate pathway Such as the prenylation of Ras and Rho to induce osteoclast apoptosis.
Biochem/physiol Actions
Zoledronic acid (zoledronate) is a bisphosphonate bone resorption inhibitor, an inhibitor of farnesyl diphosphate (FPP) synthase which results in downstream inhibition of osteoclast activity and reduced bone resorption and turnover. It has been used to treat postmenopausal osteoporosis, Paget′s disease, hypercalcemia, and along with cancer chemotherapy to treat bone damage caused by cancer that has spread to the bones.
in vitro
Zoledronic Acid monohydrate (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 monohydrate increases the expression of osteoclastogenesis supporting factor from MLO-Y4 cells.Zoledronic Acid monohydrate enhances the RANKL expression via IL-6/ JAK2/STAT3 pathway in MLO-Y4 cells.Zoledronic Acid monohydrate inhibits osteoclast differentiation and function through the regulation of NF-κB and JNK signalling pathways.Zoledronic Acid monohydrate (10-100 μM; 1-7 days) markedly reduces the viability of MC3T3-E1 cells.Zoledronic Acid monohydrate (10-100 μM; 1-7 days) induces apoptosis in MC3T3-E1 cells.Zoledronic Acid monohydrate (10-100 μM; 4 days) inhibits cell viability due to the induction of apoptosis.Zoledronic Acid monohydrate exerts inhibitory effects on the differentiation and maturation of MC3T3-E1 cells at concentrations <1 μM.
in vivo
Zoledronic Acid monohydrate (0.05 mg/kg; i.p.; weekly; for 3 weeks) increases bone mineral density and content.Zoledronic Acid monohydrate (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.
