Unifiram
Based on 1 Customer Validation
Unifiram (DM232) is a AMPA receptor activator and cognitive enhancer. Unifiram activates the AMPA-mediated neurotransmission system. Unifiram reverses NBQX-induced amnesia in the passive avoidance test in mice. Unifiram reverses the antagonistic effect of kynurenic acid on NMDA-mediated [3H]NA release in rat hippocampal slices. Unifiram enhances excitatory synaptic transmission in the rat hippocampus in vitro. Unifiram can be used in studies related to amnesia and cognitive dysfunction, including age-related memory decline, neurodegenerative diseases such as Alzheimer's disease or Parkinson's disease, multiple sclerosis, schizophrenia, and attention deficit hyperactivity disorder.

AMPA Receptor |
NMDA Receptor |
Unifiram (0-1 µM; 30-95 min of superfusion) reverses the inhibitory effect of Kynurenic acid (HY-100806) on NMDA-evoked [3H]NA release in rat hippocampal slices via an AMPA receptor-dependent mechanism, with an EC50 ≤ 0.1 µM[1].
Unifiram (10 nM-1 µM; 15 min per concentration in a cumulative sequence) induces a persistent, concentration-dependent increase in fEPSP amplitude in the CA1 region of rat hippocampal slices, with an EC50 of 27 nM[1].

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 (8.38 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 (8.38 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 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.
