Biological Activity


ln Vitro Q134R (1-10 μM) inhibits calcineurin activity but reduces NFAT signaling. In primary rat astrocytes, Q134R partially reduces NFAT activity, but neither in vivo nor in vitro, it stops calcineurin-mediated dephosphorylation of a non-NFAT target[1].
ln Vivo In mouse models of AD-like disease, Q134R (4 mg/kg; oral gavage; twice daily; for 7 days) therapy improves cognitive function[1].
Animal Protocol Animal/Disease Models: APP/PS1 mice (12‐month‐old) injected with oligomeric Aβ (oAβ) peptides[1]
Doses: 4 mg/kg
Route of Administration: Orally gavage; twice per day; for 7 days
Experimental Results: Led to improved Y maze performance.

Solubility Data


Solubility (In Vitro) DMSO: 100 mg/mL (243.67 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 2.08 mg/mL (5.07 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: 2.08 mg/mL (5.07 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Solubility in Formulation 3: ≥ 2.08 mg/mL (5.07 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 2.4367 mL 12.1835 mL 24.3671 mL

10 mM 0.2437 mL 1.2184 mL 2.4367 mL
*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.
