Biological Activity
Exposure to DBAA (5-40 μM) leads to significant reduction in thymocyte proliferation in vitro[1].
DBAA (5-40 μM; for 24 hours) treatment induced cell cycle arrest. The data showed at least 40% increase in the G0/G1 phase and 50% decrease in the S phase in thymocytes treated with different concentrations of DBAA[1].
DBAA (5-40 μM; for 24 hours) decreases the expression of Bcl-2 and increases the expression of Fas/FasL[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Thymocytes from BALB/c mice
-
Concentration:0, 5, 10, 20, and 40 μM
-
Incubation Time:6, 12, 24, 48, and 72 hours
-
Result:Led to a significantly decreased cell proliferative response to T-cell mitogen for 6 hr or longer. At 6 hr, significant inhibition was observed only at 40 μM, and significant inhibition was observed for all concentrations at 24, 48, and 72 hr.
-
Cell Line:Thymocytes
-
Concentration:0, 5, 10, 20, and 40 μM
-
Incubation Time:24 hours
-
Result:The expression of Fas/FasL increased significantly from 10 μM, and the expression of Bcl-2 decreased at all concentration.
There is some evidence of carcinogenic activity of Dibromoacetic acid in female rats based on an increased incidence and positive trend of mononuclear cell leukemia[2].
There is clear evidence of carcinogenic activity of Dibromoacetic acid in male and female mice based on increased incidences of hepatocellular neoplasms and hepatoblastoma (males only). Increased incidences of lung neoplasms in male mice were also considered to be exposure related[2].

-
Animal Model:Male and female F344/N rats and B6C3F1 mice[2]
-
Dosage:Groups of five male and five female rats/mice were exposed to 0, 125, 250, 500, 1,000, or 2,000 mg/L Dibromoacetic acid in drinking water for 2 weeks
Groups of 10 male and 10 female rats/mice were exposed to 0, 125, 250, 500, 1,000, or 2,000 mg/L Dibromoacetic acid in drinking water for 3 months
Groups of 50 male and 50 female rats/mice were exposed to drinking water containing 0, 50, 500, and 1,000 mg/L Dibromoacetic acid for 2 years -
Administration:Exposed to Dibromoacetic acid (greater than 99% pure) in drinking water for 2 weeks, 3 months, or 2 years.
-
Result:Exposure to Dibromoacetic acid for 2 years caused increased incidences of cystic degeneration of the liver in male rats, increased incidences of alveolar epithelial hyperplasia and nephropathy in female rats, and increased incidences of splenic hematopoiesis in male mice.

Solvent & Solubility
DMSO : 100 mg/mL (459.05 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (11.48 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.5 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
