After being treated for 24 hours at 0.5–5 μM, GW2974 (0.5–50 μM, 3 hours) can reduce the growth of U87MG and U251MG cells and has evident cytotoxicity at 10 μM or above [1]. GW2974 (0.001-100 μM, 24 hours): There is a dose-related relationship between GW2974's effects on GBM cells and migration [1]. GW2974 (0.001-100 μM, 24 hours) prevents HN5, N87, and BT474 cells from proliferating[2]. Results: Cell viability of U87MG and U251MG in 0.5 μM and 5 μM was reduced to 89.4% and 86.3%, respectively, compared to the control. Strain: U87MG, U251MG Concentration: 0.5-50 μM Incubation time: 3 hours. An experiment on cell proliferation [1]

Low doses of GW2974 (30 mg/kg, 100 mg/kg, model, once daily) have an effect on the growth of angiogenic tumor cells and intravascular tumor growth in GBM tumors; however, in the HN5 human tumor xenograft model, high doses of GW2974 (10 mg/kg, 30 mg/kg, facial dose, twice daily) and BT474 completely eliminated the tumor inhibition effect of low-dose GW2974 [1]. In human tumor xenograft mouse models, it dramatically and dose-dependently suppressed tumor growth [2].

| Animal Protocol |
Animal/Disease Models: GBM xenograft mouse model [1]
Doses: 30 mg/kg, 100 mg/kg Route of Administration: po (oral gavage) Experimental Results: Tumor growth slowed down at doses of 30 mg/kg and 100 mg/kg . The 30 mg/kg group inhibited the invasion of the area around the tumor, but the 100 mg/kg group demonstrated enhanced tumor invasion in the brain tissue. Doses of 30 mg/kg and 100 mg/kg inhibited angiogenesis. Animal/Disease Models: CD-1 nude mice (HN5), CB-17 SCID (severe combined immunodeficient) mouse (BT474) [2] Doses: 10 mg/kg, 30 mg/kg Route of Administration: po (oral gavage) Experimental Results: Inhibition of HN5 model The therapeutic dose for tumor growth is 30 mg/kg. A therapeutic dose of 10 mg/kg inhibited tumor growth by approximately 95% in the HN5 model and approximately 50% in the BT474 model. |

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).

| 5 mM | 0.5057 mL | 2.5286 mL | 5.0573 mL | |
| 10 mM | 0.2529 mL | 1.2643 mL | 2.5286 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.
