Selank
Based on 1 Customer Validation
Selank (Selanc; TP-7) is a GABAA receptor modulator with anxiolytic activity. Selank allosterically modulates the specific binding of GABA to GABAA receptors and alters the affinity of endogenous ligands for these receptors. Selank reduces elevated anxiety levels, attenuates stress-induced exacerbation of anxiety, and produces a synergistic anxiolytic effect with diazepam. Selank can be used in the research of anxiety disorders.

Biological Activity
Selank (300 μg/kg; i.n.; once daily; 14 days) significantly mitigates stress-induced anxiety-related behavioral deterioration in UCMS-exposed rats compared to saline-treated controls[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Wistar rats (male, average weight 400 g)[1]
-
Dosage:300 μg/kg
-
Administration:i.n.; once daily; 14 days
-
Result:Decreased median time spent in open arms from 40.2 s to 12.2 s.
Increased median time spent in closed arms from 124.9 s to 147.7 s.
Decreased median number of hanging events from open arms from 7 to 5.
Decreased median number of squares crossed minimally from 36 to 30.
Maintained median number of rears at 9.5.
-
Animal Model:Wistar rats (male, average weight 400 g, UCMS-induced anxiety)[1]
-
Dosage:300 μg/kg
-
Administration:i.n.; once daily; 14 days (concurrent with UCMS exposure)
-
Result:Decreased median time spent in open arms from 64.7 s (41.7-79.4 s IQR) to 15.5 s (7-26.6 s IQR).
Increased median time spent in closed arms from 104.7 s to 139.9 s.
Decreased median number of hanging events from open arms from 9 to 4.5.
Decreased median number of squares crossed from 39 to 22.
Decreased median number of rears from 6.5 to 5.5.
Exhibited magnitude of anxiety indicator changes similar to non-stressed rats administered Selank, and significantly less severe than changes observed in UCMS-exposed rats administered saline.

Solvent & Solubility
DMSO : 50 mg/mL (66.50 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 (sealed storage, away from moisture). 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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 5 mg/mL (6.65 mM); Clear solution
