In 4T1 cells, antitumor agent-115 (SS-12) (1.25 μM, 10 μm, 40 μM, 24 hours) mostly causes apoptosis by stopping the cell cycle in the G0/G1 phase [1]. 4T1 cell migration and invasion are inhibited by antitumor agent-115 (15 μM, 30 μM, 60 μM, 24 hours) [1]. 4T1 cells undergo apoptosis when exposed to antitumor agent-115 (10 μM) for a full day [1].

ln Vivo |
Antitumor agent-115 (SS-12) exhibits a good bioavailability in rats when administered orally (10 mg stachydrine/kg equivalency, 200 μL) [1]. In breast cancer model mice, antitumor agent-115 (0.1 mL/10 g, oral treatment) exhibits antitumor effects and enhances the morphological structure of the spleen [1].

Western Blot Analysis[1] Cell Types: 4T1 cell Tested Concentrations: 10 μM Incubation Duration: 24 h Experimental Results: Improved the cleaved caspase-3 expression and and Bax expression, but inhibited the anti-apoptosis protein Bcl2 expression in 4T1 cells. |
Animal Protocol |
Animal/Disease Models: Rats[1]
Doses: 10 mg stachydrine/kg equivale, 200 μL Route of Administration: Oral administration (po) Experimental Results: demonstrated high systemic exposure with 6.10 μg/mL of Cmax value and 14.75 h μg/mL of AUC0-t value. Animal/Disease Models: Tumor-bearing mice[1] Doses: 0.2 mmol/kg Route of Administration: Oral administration (po) Experimental Results: Inhibitory rate was 51.47% ( P < 0.01) Displayed significant tumor cell shrinkage and larger void areas in tumor tissues demonstrated more weight loss than the model group and other treatment groups, increased of both AST and ALT levels and diminished spleen index of the tumor-bearing mice |

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
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).

5 mM | 0.5748 mL | 2.8739 mL | 5.7478 mL | |
10 mM | 0.2874 mL | 1.4369 mL | 2.8739 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.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
