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.  (Please use freshly prepared in vivo formulations for optimal results.) |
