|Description||Zoledronic acid (ZA), a potent osteoclast inhibitor, induces apoptosis in osteoclasts by inhibiting enzymes of the mevalonate pathway and preventing the isoprenylation of small GTP-binding proteins such as Ras and Rho.|
Zoledronic acid (10 µM and 100 µM) causes a significant reduction in the proportions of MCF-7 cells (49.54% and 23.55% of control, respectively) (P < 0.05). Zoledronic acid has little effect on MDA-MB-231 cells at concentrations of 0.1–10 µM, whereas the 100 µM concentration results in a significant reduction in cell number. Zoledronic acid (100 µM) results in a 63.5% reduction in MCF-7 cell number at 72 hours and an 87.1% reduction at 96 hours. Zoledronic acid (10 µM) results in a greater than 4-fold increase in MCF-7 cell apoptosis whereas the 100 µM concentration induces a 6-fold increase in the proportion of apoptotic cells. Zoledronic acid (10 µM) and paclitaxel (2 µM) results in a 5-fold increase in apoptosis (774.8% of control) compared to zoledronic acid alone (155.71%) and a 4-fold increase compared to paclitaxel alone (189.68%). Zoledronic acid-induced apoptosis of MCF-7 breast cancer cells can be inhibited by addition of intermediates of the mevalonate pathway, which is consistent with observations in osteoclasts, macrophages and myeloma cells.  Zoledronic acid enhances OPG gene expression and protein secretion by human osteoblasts (hOB) in a dose-dependent fashion with a maximum effect at 10 nM after 72 hours, consistent with the higher biological potency of Zoledronic acid. Zoledronic acid prevents the inhibitory effects of the glucocorticoid dexamethasone on OPG mRNA and protein production in human osteoblasts. Zoledronic acid induces type I collagen secretion and alkaline phosphatase activity by 2- and 4-fold, respectively, in human osteoblasts. 
|In vivo||Zoledronic acid (120 mg/kg, s.c.) prevents the formation of lesions, prevents cancellous bone loss and loss of bone mineral density, and reduces osteoclast perimeter in 5T2MM-bearing mice. Zoledronic acid (120 mg/kg, s.c.) also decreases paraprotein concentration, decreases tumor burden, and reduces angiogenesis in 5T2MM-bearing mice. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
