β-D-Galactose pentaacetate
Based on 1 Customer Validation
β-D-Galactose pentaacetate is a negative regulator of insulin with plasma membrane penetrating ability and can be hydrolyzed by intracellular esterases. β-D-Galactose pentaacetate inhibits Leucine (HY-N0486)-induced insulin release in Wistar rat islets, potentially preventing excessive insulin release in pathological conditions.

Biological Activity
β-D-Galactose pentaacetate (1.7 mM) significantly inhibits the insulin release induced by Lleucine but has no significant effect on insulin release induced by dimethyl ester of succinic acid in rat pancreatic islets[1][2][3].
β-D-Galactose pentaacetate (1.7 mM) significantly reduces the utilization of D-[5-³H] glucose and the production of ¹⁴C-labeled acidic metabolites, but does not affect the oxidation of D-glucose in rat pancreatic islets [2].
β-D-Galactose pentaacetate (1.7 mM) lightly reduces the ⁴⁵Ca uptake stimulated by leucine, but does not affect the calcium intake under basal conditions or glucose stimulation in rat pancreatic islets [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: ≥ 5 mg/mL (12.81 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 5 mg/mL (12.81 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
