Silydianin
Based on 1 publication(s) in Google Scholar
Silydianin is a flavonolignan. Silydianin can be obtained from Silybum marianum. Silydianin inhibits PTP1B with an IC50 of 17.38 μM. Silydianin inhibits both monophenolase and diphenolase of tyrosinase significantly, with IC50s of 2.6 μM and 16.5 μM, respectively. Silydianin induces Apoptosis and reduces cytokines (IL-4 and IL-5). Silymarin has antioxidant, cytoprotective and immunomodulatory effects. Silydianin has antitumor activity against prostate cancer. Silymarin can be used in allergic asthma research.

Silydianin inhibits both monophenolase and diphenolase of tyrosinase significantly, with IC50s of 2.6 μM and 16.5 μM for monophenolase and diphenolase, respectively[1].
Silydianin (0.1-100 μM; 2-24 h) slightly induces apoptosis of stimulated and unstimulated neutrophils[2].
Silydianin (10-100 μM; 30 min) displays concentration-dependent cytoprotection against the toxic effects of Allyl alcohol and Carbon tetrachloride (HY-Y0298) in primary human hepatocytes[3].
Silydianin (30-90 μM; 72 h) is slightly growth inhibitory in DU145 and PC3 cells[4].

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 (4.31 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
