Biological Activity
4-Br-Bnlm (0-100 µM; 24 h) inhibits 1477N mutant myocilin in human embryonic kidney (HEK) cells expression[1].
4-Br-Bnlm (30 µM; 24 h) reduces mutant myocilin levels and toxicity in primary human trabecular meshwork (HTM) cells[1].
4-Br-Bnlm (3, 10 and 30 µM; 24 h) inhibits myocilin secretion with dose-dependent manner in myocilin cell[1].
4-Br-Bnlm (30 µM and 100 µM; 24 h) doesn’t induces a heat shock response in the HTM cells[2].

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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.37 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
