Perfusion of the TMN with ABT-239 (10 μM) increases histamine release from the TMN, NBM, and cortex, but not from the striatum or NAcc. TMN perfusion with ABT-239 activates c-Fos selectively in the NBM and cortex[4].

Solvant et solubilité
DMSO : ≥ 100 mg/mL (302.65 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
* "≥" means soluble, but saturation unknown.
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 (7.57 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (7.57 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

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.
Protocole
Solutions of KA, ABT-239 and SVP are prepared in pyrogen-free normal saline for injection except for TDZD-8, which is dissolved in 10% DMSO and are administered intraperitoneally in a volume not exceeding 10 mL/kg. The animals are divided into ten groups. The first group (CTRL) receive vehicle (0.9% sodium chloride) only whereas animals in the second group (VEH) are given vehicle followed by KA at a dose of 10 mg/kg, i.p. (pH 7.2±1), this being the dose that induces low-grade seizures (stage 0-4) in all the animals without any mortality in a range finding study. The KA dose employs to evoke SE in mice in various studies mostly varied from as low as 6-20 mg/kg to as high as 25-45 mg/kg. Animals in the next two groups are administered ABT-239 in increasing doses of 1 (AL) and 3 mg/kg (AH) 30 min before KA challenge. These doses ranging from 0.1 to 3 mg/kg of ABT-239 display disease modifying attributes in a mice model of Alzheimer׳s disease as well as improved cognitive functions. The fifth and sixth group receive graduated doses of 150 (SL) and 300 mg/kg (SH) of SVP 30 min prior to KA injection. The seventh and eight group receive combinations of subeffective dose (maximum possible dose at which there is no protection) of SVP at 150 mg/kg with ABT-239 at 1 (SLAL) and 3 mg/kg (SLAH) respectively followed 30 min later by KA. The remaining two groups receive low dose combination at 1 and 5 mg/kg (ALTL) and a high dose combination at 3 and 10 mg/kg (AHTH) of ABT-239 and TDZD-8, respectively before KA exposure. The doses of TDZD-8 chosen are based on previous studies where doses ranging from 1 to 10 mg/kg reduced inflammation and tissue injury as well as improve psychiatric conditions.
