Biologische Aktivität
Amyloid-β[1]
MDR-1339 is an Aβ-aggregation inhibitor, and shows no significant inhibition a panel of CYP isozymes, while it slightly inhibits CYP2C8 (IC50, 31.4 μM). MDR-1339 (3.1-50 μM) dose-dependently blocks the formation of Aβ aggregates, and disaggregates Aβ fibrils. MDR-1339 (1.5-10 μM) also protects cells from this Aβ-induced toxicity[1].

Lösungsmittel & Löslichkeit
DMSO : 100 mg/mL (306.38 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (7.66 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protokoll
HT22 cells, a murine cell line of hippocampal origin, are grown in Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal bovine serum and 5% penicillin/streptomycin. At the outset, 90% confluent cells are dissociated and plated at 5 × 103 cells/well in a 96-well plate. When the cells are attached to the plate, the medium is replaced with plain DMEM. The cells are treated with MDR-1339. One hour after MDR-1339 treatment, 4 μL of pre-diluted 25 μM Aβ42 is added to the media, and the cells are further incubated for 18 h. For the determination of cell viability, 15 μL of 5 mg/mL MTT is added to each well and incubated for 3 h. The formazan that formed is dissolved in DMSO, and the absorbance is measured at 570-630 nm using a plate reader[1].

For this study, a total of 24 (n = 8 for each group) APP/PS1 [B6C3-Tg (APPswe, PSEN1dE9) 85Dbo/J] Tg mice are utilized. The mice are housed in a controlled environment under standard room temperature, relative humidity and a 12 h light/dark cycle with free access to food and water. APP/PS1 treated groups are orally administered with MDR-1339 at a dose of 30 or 100 mg/kg body weight once daily. MDR-1339 treatment is at the age of 29 weeks, and the treatment is conducted for 8 weeks[1].
