GB2095
Based on 1 Customer Validation
GB2095 is an orally active and selective galectin-3 inhibitor. GB2095 shows superior selectivity for both human (KD = 0.036 μM) and mouse galectin-3 (KD = 0.35 μM) over other galectins (such as h-Gal-1/4N/4C/8N/8C/9N/9C and m-galectin-1). GB2095 inhibits tumor growth in syngeneic mouse models of breast and melanoma cancers. GB2095 can be used for breast and melanoma cancer research.

GB2095 displays a 14-fold selectivity for human galectin-3 over the other tested human galectins (Gal-1, -4N, -4C, -8N, -8C, -9N, -9C) on average, and shows a more pronounced (100-fold) selectivity for mouse galectin-3 over mouse galectin-1[1].
GB2095 shows high permeability and no efflux over a CACO-2 cell monolayer, alongside good hepatic stability in both humans and mice, and exhibits moderate plasma protein binding in both human and mouse plasma[1].

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 (4.56 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.
