Biological Activity
|
PKC 11.9 nM (Ki) |
By use of a cell line derived from an Alzheimer’s disease patient, significant enhancement of sAPPα secretion is achieved at 1 μM concentration for TPPB (Compound 5e)[1]. TPPB has a role against Aβ25-35-induced neurotoxicity in PC12 cells. TPPB at concentration of 1 μM could antagonize Aβ25-35 induced cell damage. TPPB could increase the phosphorylation of Akt, PKC, MARCKS and MAPK, which are inhibited by Aβ25-35 treatment. TPPB inhibits the activation of caspase-3 induced by Aβ25-35[2].

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: ≥ 2.25 mg/mL (4.49 mM); Clear solution
This protocol yields a clear solution of ≥ 2.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.5 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.
Protocol
24 h after plating 2×104 pheochromocytoma PC12 cells in each well of a 96 well plate, cells are incubated with TPPB at a series of concentration (0.1, 0.5, 1, 5, 10, 20 μM). Twelve to 24 h later, the original media is replaced with media containing MTT at a final concentration of 0.5 g/L for 4 h. Cell viability is evaluated with MTT assays[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice: Mice are 7 weeks old at the beginning of the treatments and are in the resting phase of the hair cycle. TPPB is applied once or else are applied twice weekly for a total of four applications. Two animals are treated at each dose of compound, and 72 h after the last application, the animals are euthanized. Two portions of treated skin are removed from each animal, fixed in neutral buffered formalin, and stained with hematoxylin and eosin for histological analysis[1].
