Alrestatin
Based on 1 publication(s) in Google Scholar
Alrestatin (AY-22284) is an aldose reductase inhibitor. Alrestatin reduces fructose levels in the uterine fluid of mice. Alrestatin interferes with sperm capacitation and impairs fertilization function in mice. Alrestatin decreases basal and tyramine-induced norepinephrine release in rat pancreatic specimens in vitro. Alrestatin enhances glucose- and arginine-stimulated insulin secretion in vivo. Alrestatin can be used in studies related to diabetes and reproductive diseases.

Biological Activity
Alrestatin (1-5 mg/mL; 15 min) dose-dependently inhibits basal and tyramine-stimulated 3H-norepinephrine release from rat splenic and pancreatic tissue samples in vitro[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Alrestatin (0.15 μg/μL; intrauterine infusion) significantly reduces fructose levels in mouse uterine fluid without altering glucose or sorbitol levels[2].
Alrestatin (1.5 mmol/L; intrauterine injection) significantly reduces sperm capacitation rate and fertilization rate in mice, while co-administration of fructose or sorbitol reverses these effects[2].

Solvent & Solubility
DMSO : 50 mg/mL (195.90 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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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 (9.80 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (9.80 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
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.
