LLK203 (0-100 μM; 36 h) demonstrates high inhibitory activity on MCF-7 cells (IC50=3.4 μM) compared with ML364 (IC50=9.3 μM). LLK203 demonstrates a 4-fold increase in USP2 activity and a 9-fold increase in USP8 activity compared to ML364 (HY-100900)[1].
LLK203 (10-50 μM; 24 h) increases the ratio of apoptotic cells and remaines largely in G1 phas on MCF-7 cells[1].
LLK203 (2-50 μM; 24 h) can degrade various proteins (MDM2, Cyclin D1, Her2, ERα) in a dosedependent manner[1].
LLK203 (2-50 μM; for 7 days) shows a robust ability of inhibiting clone formation at the concentration of 10 μM[1].

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.
