In Vitro

YK-3-237 exhibits the anti-proliferative activities toward most of the breast cancer cell lines tested at submicromolar concentration. YK-3-237 preferentially inhibits the proliferation of breast cancer cell lines carrying mtp53[1].
YK-3-237 inhibits the proliferation of triple-negative breast cancer (TNBC) HS578T, MDA-MB-453, SUM1315MO2, SUM149PT, BT549, MDA-MB-231, MDA-MB-436, MDA-MB-468, HCC1937 with IC50s of 0.160±0.043, 0.241±0.086, 0.253±0.028, 0.289±0.066, 0.353±0.017, 0.431±0.136, 0.501±0.062, 1.436±0.754, 5.031±2.010 μM, respectively[1].
YK-3-237 inhibits the proliferation of Luminal T47D, MCF7, and ZR-75-1 with IC50s of 1.573±0.370, 2.402±0.256, 3.822±0.967 μM, respectively[1].
YK-3-237 inhibits the proliferation of HER2 BT474 and SK-BR-3 with IC50s of 1.249±0.372 and 0.346±0.066 μM, respectively[1].
YK-3-237 (0.01-10 μM; 24 hours) deacetylates mtp53 in TNBC cell lines[1].
YK-3-237 is a potent activator of Sirt1, on the activation of renal interstitial fibroblasts using NRK-49F cells[2].
Exposure of cells to YK-3-237 also significantly reduces expression of α-SMA and fibronectin in a dose-dependent manner, with the maximum inhibition occurring at 10 μM[2].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (6.72 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.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (6.72 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
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
