TAK-778, a derivative of ipriflavone, has been shown to induce bone growth both in vitro and in vivo. Recently, it has been shown that TAK-778 can enhance osteoblast differentiation of human bone marrow cells via an estrogen receptor (ER)-dependent pathway. TAK-778 enhanced bone formation in OVX rats and that this effect was dependent on an ER-mediated pathway.
| ln Vitro |
It has been demonstrated that the isoflavone derivative TAK-778 stimulates bone formation in both in vitro and in vivo models. Increased mineralized nodule area was seen after 1 to 21 days of continuous treatment with TAK-778 (10 μM). Cellular alkaline phosphatase (ALP) activity is considerably stimulated by TAK-778 at doses of 1 μM or above. Confluent-stage cells' DNA content rose by TAK-778, albeit not very much. Additionally, from days 5 to 7, TAK-778 administration led to a dose-dependent increase in the amount of soluble collagen and osteocalcin secreted into the culture medium. TAK-778 increased the secretion of TGF-β and IGF-I at every stage of the treatment. 21 days devoted to culture. TAK-778 treatment of the cells increased the saturated cell density in a dose-dependent manner but did not cause ALP activity. Saturated cell density is dramatically reduced by TAK-778 at a dose of 10 μM [2].

| ln Vivo |
Following a single topical application of TAK-778/PLGA-MC (0.2 to 5 mg/site), the radiopaque area generated in the defect increased in a dose-dependent manner. According to histological investigations, a bony bridge filled the deficiency area, and the newly produced radiopaque area, which was encircled by cuboidal osteoblasts and thick osteoid seams, matched to calcified bone encompassing the medullary cavity. No discernible variations were observed in the indices between the skulls treated with TAK-778/PLGA-MC and placebo. TAK-778/PLGA-MC particles triggered radioactive bone repair across the defect two months post-surgery [2]. When OVX mice were given TAK-778 orally, their lumbar spine bone mineral density (BMD) increased more than that of vehicle controls [3].

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).

*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.
