CMC2.24 (TRB-N0224), an oral active tricarbonylmethane agent that inhibits Ras activation and the downstream effector pathway ERK1/2 to effectively treat pancreatic tumors in mice. The zinc-dependent MMPs are also effectively inhibited by CMC2.24, whose IC50 values range from 2.0 to 69 μM. By reestablishing cartilage homeostasis and preventing chondrocyte apoptosis through the NF-κB/HIF-2α axis, CMC2.24 slows the progression of osteoarthritis.

ln Vitro	CMC2.24 (0-60 μM; 24 hours) inhibits the growth of pancreatic cancer in vitro[1]. In pancreatic cancer cells, CMC2.24 lowers the phosphorylation levels of STAT3Ser727, causes mitochondrial reactive oxygen species, and causes mitochondrial cell death. CMC2.24 causes intrinsic apoptosis and mitochondrial reactive oxygen species to be produced[1].
ln Vivo	CMC2.24 (50 mg/kg; p.o.; five times weekly for 17 days) prevents pancreatic cancer xenografts from growing[1]. CMC2.24 has a potent cytokinetic effect that prevents human PC from growing. In PC cells and xenografts, CMC2.24 inhibits the ERK signaling pathway[1].

Solubility (In Vivo)

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 (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *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)] *Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Oral Formulation 3: Dissolved in PEG400 Oral Formulation 4: Suspend in 0.2% Carboxymethyl cellulose Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose Oral Formulation 6: Mixing with food powders Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.  (Please use freshly prepared in vivo formulations for optimal results.)

*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.
