Dehydrocostus Lactone ((-)-Dehydrocostus lactone) is a natural sesquiterpene that can be isolated from Saussurea lappa. Dehydrocostus Lactone has multiple activities such as anti-inflammatory, antibacterial, anti-tumor, and immunomodulatory effects. Dehydrocostus Lactone has an MIC of 2 µg/mL against Mycobacterium tuberculosis. Dehydrocostus Lactone can also inhibit the killing activity of cytotoxic T lymphocytes and induce apoptosis in tumor cells.

In Vitro

Dehydrocostus lactone (0-2 mg/L; 48 h) can reduce the viability, induce apoptosis, inhibit the expression of anti-apoptotic proteins, and increase the expression of pro-apoptotic proteins in DU145 cells^[1].

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 3

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

Solubility: ≥ 2.08 mg/mL (9.03 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

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.
