Fasoracetam
Based on 1 Customer Validation
Fasoracetam (NS105) is an orally active metabotropic glutamate receptor (mGluR) activator. Fasoracetam bidirectionally regulates adenylyl cyclase activity and cAMP levels by activating group I-III mGluRs, upregulating GABAB receptors, and enhancing cholinergic neurotransmission. Fasoracetam can be used in research on attention deficit hyperactivity disorder (ADHD), depression, dementia, Alzheimer's disease, and forebrain ischemia.

In Vitro
Fasoracetam (1 μM; 10-60 min) increases [35S]GTPγS binding in intact cell membranes of rat cerebral cortex[3].
Fasoracetam (10 nM-1 μM; 10 min) has activity in enhancing Isoproterenol (HY-B0468)-stimulated cAMP accumulation in rat cerebral cortex slices[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Fasoracetam (1-100 mg/kg; p.o.; single administration; 40 min before testing) ameliorates memory impairment in a Baclofen (HY-B0007)-induced passive avoidance memory disruption model in Wistar rats[4].
Fasoracetam (3-30 mg/kg; p.o.; single administration; immediately after electroconvulsive shock) prevents memory impairment in a Wistar rat model of electroconvulsive shock (ECS)-induced memory disruption[4].
Fasoracetam (10-100 mg/kg; p.o.; once daily; 14 days) reverses memory impairment in AF64A- or cerebral ischemia-induced radial arm maze Wistar rat models[4].
Fasoracetam (10 mg/kg; p.o.; single administration) increases cerebral cortical acetylcholine (ACh) release in awake, freely moving Wistar rats[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo:
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: ≥ 2.08 mg/mL (10.60 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 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: ≥ 2.08 mg/mL (10.60 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.
