| Animal Protocol |
Six‑month‑old A53T α‑synuclein transgenic mice and wild‑type littermates were administered Chicago Sky Blue 6B by intraperitoneal injection at 20 mg/kg/day, once weekly for 3 months; control groups received PBS[4]
After treatment, mice underwent behavioral tests (open field, grip strength, balance beam) followed by perfusion, brain sectioning, and immunohistochemical analysis of pS129 α‑synuclein and GFAP[4] |

Interactions
Chicago Sky Blue (also known as Niagara Sky Blue) is an important dye that has been successfully used as a target for intravascular energy absorption in helium-neon lasers. This light/dye interaction leads to endothelial damage, the extent of which can be controlled by adjusting the laser irradiation time and the amount of dye injected intravenously. Endothelial damage is likely due to the heat generated by the dye absorbing energy at the plasma-endothelial cell interface. The mildest damage results in the selective loss of the vasodilatory effects normally produced by acetylcholine and bradykinin (two endothelium-dependent vasodilators). The vasodilatory effects produced by sodium nitroprusside (a vasodilator that acts directly on vascular smooth muscle) are preserved. More severe damage (e.g., longer light exposure time and/or more dye) can lead to localized platelet aggregation at the laser irradiation site. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 4.17 mg/mL (4.20 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 41.7 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: ≥ 4.17 mg/mL (4.20 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 41.7 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. View More
Solubility in Formulation 3: 5 mg/mL (5.04 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication. |

*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.
