MBC-11 strongly suppressed the proliferation of all three cell lines between 10-8 and 10-4 M, exhibiting similar activity patterns. KAS-6/1 cell growth was decreased by MBC-11 from roughly 56% at 10-8 M to 6% at 10-8 M. 10-5 M [1]

| ln Vivo |
In patients treated with PBS (90%) or 0.04 μg/day zoledronate (100%), the incidence of bone metastases was reduced by 40% by MBC-11 (0.04 μg/day, subcutaneous). In comparison to mice given PBS or zoledronate, MBC-11 also dramatically decreased the burden of bone tumors [1]. Mice given 500 μg/day of MBC-11 experienced weight increase comparable to the PBS-treated group [1]. These findings suggest that MBC-11 merits more research as a treatment for tumor-induced bone disease (TIBD) since it can lessen the burden of bone tumors, preserve bone structure, and possibly increase overall survival [1].

Cell proliferation assay[1]
Cell Types: human multiple myeloma cell lines (KAS-6/1, DP-6, KP-6). Tested Concentrations: between 10-8 and 10-4 M. Incubation Duration: 48 hrs (hours). Experimental Results: Significant inhibition of multiple myeloma cell proliferation across cell lines at most concentrations tested. |
| Animal Protocol |
Animal/Disease Models: Approximately 4weeks old female balb/c (Bagg ALBino) mouse are inoculated (subcutaneously (sc) (sc) into their mammary fat pad) with 500,000 4T1/luc cells (a mammary tumor model) on day 0 [1].
Doses: 0.04, 0.4 or 4.0 mcg/day. Route of Administration: Daily subcutaneous injection from days 7 to 21. Experimental Results: 47% of 17 mice treated with MBC-11 developed detectable bone metastases. |

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).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 1.7326 mL | 8.6631 mL | 17.3262 mL | |
| 5 mM | 0.3465 mL | 1.7326 mL | 3.4652 mL | |
| 10 mM | 0.1733 mL | 0.8663 mL | 1.7326 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. 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.
