TPCK (L-1-Tosylamido-2-phenylethyl chloromethyl ketone; L-TPCK) is an effective serine protease inhibitor and also a blocker of the PDK1/Akt pathway. TPCK can modify the E7 protein in actively keratinocyte cells. TPCK can induce cellular apoptosis, suppress tumor growth, reduce hypoxic-ischemic brain injury in rat pups, and affect vascular permeability in inflamed rats.

In Vitro

TPCK shows slight toxicity to mammalian cells (CC₅₀ = 138.8 µM), but it significantly inhibits the pre-flagellate morphology of L. amazonensis PH8 and Josefa strains (IC₅₀ values of 14.6 µM and 31.7 µM, respectively), with an IC₅₀ value of 11.3 µM for the pre-flagellate morphology of L. infantum. Additionally, TPCK is also effective against the intracellular amastigote form, showing IC₅₀ values of 14.2 µM and 16.6 µM for L. amazonensis PH8 and Josefa strains, and 21.7 µM for the amastigote form of L. infantum^[2].
TPCK (40 μM, 1 h) enhances wortmannin-dependent caspase activity in LNCaP cells but inhibits TRAIL-dependent caspase activity^[3].
TPCK (40 μM, 1 h) inhibits the formation of TRAIL-DISC in PC3 cells but does not inhibit the formation of Fas-DISC and reduces caspase2 levels^[3].
TPCK (0-40 μM, 24 h) kills PC3 cells in a dose-dependent manner, inducing apoptosis^[3].
TPCK (40 μM, 3 h) reduces the level of BAD-ser136 in LNCaP cells and eliminates AR in the cytoplasm and granules^[3].

Stock Solution Working Solution

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: ≥ 2.5 mg/mL (7.11 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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
