Triptophenolide (Hypolide) is a colorless crystal isolated from the ethyl acetate extract of Tripterygium wilfordii. Triptophenolide is an orally active pan‑antagonist of the androgen receptor (AR) with an IC₅₀ of 467 nM against human wild‑type AR. Triptophenolide reduces AR expression, inhibits AR nuclear translocation, downregulates prostate‑specific antigen mRNA levels, and suppresses the growth of AR‑positive prostate cancer cells. Triptophenolide shows anti-tumor effects against breast cancer by inhibiting cell proliferation and migration, inducing G1-phase arrest and apoptosis, repressing xenograft tumor growth. Triptophenolide inhibits pyroptosis, alleviates tissue inflammation, and ameliorates synovial injury. Triptophenolide can be used for the study of prostate cancer, rheumatoid arthritis and breast cancer.

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 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (8.00 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 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 (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
