In a concentration-dependent manner, PE859 prevents full-length tau aggregation and 3RMBD caused by heparin. The last measurement cycle's estimated IC50 values for each assay were 2.23 μM and 0.81 μM, respectively. PE859 forms β-sheet structures that prevent tau aggregation [2].

PE859 has the ability to penetrate the blood-brain barrier and permeate into central nervous system tissues. PE859 reached its maximal concentrations in the blood at 2.005 μg/mL and the brain at 1.428 μg/g after three and six hours, respectively. In JNPL3 mice, PE859 postpones the onset and development of motor impairment. PE859 inhibits the aggregation of tau protein that is sarkosyl-insoluble, hence delaying the evolution of motor dysfunction. [2]

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.57 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 (5.57 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.) |

| 10 mM | 0.2230 mL | 1.1148 mL | 2.2295 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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
