Biological Activity


ln Vitro In N2a cells, primary neurons, and brain lysates, Aftin-4 specifically and effectively raises Aβ1-42 with an EC50 value of about 30 μM [1].
ln Vivo Aftin-4 raises Aβ1-42 levels in mice and causes a fast onset of long-lasting toxicity that strongly resembles Alzheimer's disease (AD). The animals were killed between three and fourteen days after injecting varying doses of Aftin-4 (3 to 20 nmol/mouse) into the lateral ventricle. Using a mouse ELISA technique, the amount of Aβ1-42 or Aβ1-40 in the dissected hippocampus was determined. In a dose-dependent manner, Aftin-4 raises the content of Aβ1-42 to a maximum of +216% at the highest studied dose [1].

Solubility Data


Solubility (In Vitro) DMSO : ≥ 100 mg/mL (~271.39 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 2.5 mg/mL (6.78 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 25.0 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: ≥ 2.5 mg/mL (6.78 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 25.0 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: ≥ 2.5 mg/mL (6.78 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 25.0 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 2.7139 mL 13.5693 mL 27.1385 mL
5 mM 0.5428 mL 2.7139 mL 5.4277 mL
10 mM 0.2714 mL 1.3569 mL 2.7139 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.
