Description

TPPB is a cell-permeable benzolactam-derived protein kinase C (PKC) activator with a Ki of 11.9 nM.

IC50 & Target[1]

PKC

11.9 nM (Ki)

In Vitro

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].

In Vivo:

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.

  • Protocol 1

    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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.25 mg/mL (4.49 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.25 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.5 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay
[2]

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration
[1]

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
