Davunetide
Based on 1 publication(s) in Google Scholar
Davunetide is an eight amino acid snippet derived from activity-dependent neuroprotective protein (ADNP), a neurotrophic factor that exists in the mammalian CNS. Davunetide possesses neuroprotective, neurotrophic and cognitive protective roperties. Davunetide, a microtubule-stabilizing peptide, interacts with and stabilises neuron-specific βIII-tubulin in vitro. Davunetide penetrates the blood-brain barrier and is non-toxic. Davunetide inhibits Aβ aggregation and Aβ-induced neurotoxicity.

Animal Model:Male Sprague-Dawley rats (Induced by an i.p. streptozotocin (STZ) injection)[3]
-
Dosage:2 μg/kg
-
Administration:Intranasally beginning on the day following the STZ injection and were given daily, 5 days a week, for 16 weeks
-
Result:Impaired spatial memory of the diabetic rats was observed in the water maze by attenuated learning curve and worsened performance in the probe memory test. Davunetide treatment significantly improved both measurements.

Solvent & Solubility
DMSO : 125 mg/mL (151.53 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 100 mg/mL (121.22 mM; Need ultrasonic)
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.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (2.52 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
