Helichrysetin (0-100 μM, 48 h) inhibits the development of ductal carcinoma in situ (DCIS) by targeting DNA inhibitor 2 (ID2) [2].
Helichrysetin (5-20 μg/mL, 48 h) can block the cell cycle and induce apoptosis in A549 human lung cancer cells[2].
Helichrysetin (10-40 μM, 48 h) inhibits the growth of gastric cancer cells by targeting mTOR/p70S6K/c-Myc/ PDHK1-mediated energy metabolic reprogramming of cancer cells[3].

Cell Line:MGC803
-
Concentration:10, 20 40 μM
-
Incubation Time:24 h
-
Result:Reduced the mRNA and protein expression of PDHK1 and LDHA but only decreased the mRNA level of LDHB. Decreased the protein expression of pyruvate dehydrogenase phosphatase (PDP) 2 and the ratio of p-PDHA1/PDHA1. Increased the expression levels of Nrf2, HO-1, and NQO-1 and reduced Keap1. Inhibited the phosphorylation of PI3K, Akt, mTOR, and P70S6K.

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: ≥ 2.08 mg/mL (7.27 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
