(S)-Oxiracetam (1, 10, 100 μM; 24 h) stimulates PI3K/Akt/GSK3β signaling that is reliant on α7 nAChR and shields the shell of fetal rat primary cortical neurons from OGD/R injury[1]. [1]

| ln Vivo |
(S)-Oxiracetam (IV once daily for seven days; 0.12, 0.24, and 0.48 g/kg) considerably minimizes the extent of the infarct and mildly modifies Sprague behavior-MACO/R model in solution caused by Dawson simulation Inhibitory and dysfunctional When administered intraperitoneally 60 minutes before to apomorphine, salted remoxipride (0.1-100 μM/kg) prevents vomiting in dogs and apomorphine-induced behavior in rats [1]. In striatal and extrastriatal areas, (S)-Remopride hydrochloride (0.1–10 mg/kg; intraperitoneally; 30 minutes prior to apomorphine) displaces [3H]spiperone [1].

Western Blot Analysis [1] Cell Types: fetal mouse primary cortical neurons Tested Concentrations: 1, 10, 100 μM Incubation Duration: 24 h Experimental Results: α7 nAChR expression increased (1 μM increased by 46.95%, 58 |
| Animal Protocol |
Animal/Disease Models: Swiss albino mouse scopolamine-induced amnesia model [1].
Doses: 0.12, 0.24, 0.48 g/kg, one time/day for 7 days Route of Administration: intravenous (iv) (iv)injection Experimental Results: Compared with the sham operation group, the infarct area of rats was diminished to 26.04 ± 1.07%, 21.66 ± 2.27% , 12.26 ± 5.59% group were 0.12 g/kg, 0.24 g/kg, and 0.48 g/kg respectively. Neurologic scores improved compared with the MCAO/R group. Neurons were protected from apoptosis compared with the sham group. Compared with the MCAO/R group, the phosphorylated expression of α7 nAChR, as well as PI3K, Akt and GSK3β was increased. GSH-PX concentrations increased (189.54 units, 193.07 units, and 203.98 units, respectively). |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
