ln Vitro |
Using Cl-NQTrp, pre-formed PHF6 peptide fibrils were effectively disassembled[1]. PHF6 peptide oligomers may undergo structural modifications as a result of Cl-NQTrp[1].

ln Vivo |
Since Cl-NQTrp targets both Aβ and tau aggregation, it may offer a novel therapeutic option for AD[2]. The shortened life span of htau-expressing flies is greatly reduced by Cl-NQTrp, resulting in 58% viability on day 29[2].

Animal Protocol |
Animal/Disease Models: Virgin females, carrying either the eye GMR -Gal4 driver or the pan-neuronal driver elavc155 -Gal4 on chromosome X, were collected and crossed with males carrying UAS-h tau on the 2nd chromosome or with wild-type Oregon- R (OR) males as a control[2].
Doses: 0.75 mg/mL. Route of Administration: Dripped every other day. Experimental Results: Inhibited PHF6 aggregation and ameliorates eye neurodegeneration Drosophila overexpressing the human tau protein (htau). |

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.27 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 (5.27 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 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.  (Please use freshly prepared in vivo formulations for optimal results.) |

10 mM | 0.2533 mL | 1.2664 mL | 2.5329 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.
