In osteocyte-like MLO-Y4 cells, zoledronic acid disodium tetrahydrate (0.1–1 µM; 48 hours) enhances the expression of sclerostin and receptor activator of nuclear factor kB ligand (RANKL) mRNA [2]. In MLO-Y4 cells, zoledronic acid disodium tetrahydrate can upregulate the expression of factors supporting osteoclastogenesis [2]. Through the IL-6/JAK2/STAT3 pathway, zoledronic acid disodium tetrahydrate increases RANKL expression in MLO-Y4 cells [2]. By controlling the NF-κB and JNK signaling pathways, zoledronic acid disodium tetrahydrate suppresses osteoclast differentiation and function [3]. Zoledronic Acid disodium tetrahydrate (10-100 µM; 1-7 days) dramatically lowers the viability of MC3T3-E1 cells and causes them to undergo apoptosis [4]. Because it induces apoptosis, zoledronic acid disodium tetrahydrate (10–100 µM; 4 days) reduces cell viability [4]. At concentrations less than 1 µM, zoledronic acid disodium tetrahydrate prevents MC3T3-E1 cells from differentiating and maturing [4].

ln Vivo |
Zoledronic acid disodium tetrahydrate (0.05 mg/kg; intraperitoneally; weekly; for 3 weeks) improves bone mineral density and content [5]. Zoledronic acid disodium tetrahydrate (0.5-1 mg/kg; i.p.; weekly; for 3 weeks) suppresses osteoclast and osteoblast function and bone remodeling in vivo, interfering with bone mechanical characteristics [5].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
