Sm4 is a selective and orally active SOX18 inhibitor. Sm4 inhibits SOX18-DNA binding (IC50 = 97.5 μM); Sm4 disrupts the SOX18-RBPJ protein-protein interaction (IC50 = 42.3 μM). Sm4 blocks SOX18 DNA binding, disrupts multiple SOX18 protein-protein interactions with RBPJ, DDX1, DDX17, ILF3, SOX7 and STAT1, modulates SOX18 chromatin binding dynamics. Sm4 exerts anti‑angiogenic and anti‑lymphangiogenic effects, reduces tumor vascular density, triggers vascular defects in zebrafish, prolongs survival in mouse metastatic cancer models. Sm4 can be used for the research of breast cancer.

体外実験

Sm4 (0.2 μM-3 mM) inhibits full-length mouse SOX18-DNA binding with an IC50 of 97.5 μM in a FP competition assay, with no aggregation observed up to 1000 μM[1].
Sm4 (0.3-300 μM; 1 h) selectively disrupts SOX18-RBPJ interactions with IC50 values of 42.3 μM[1].
Sm4 inhibits DNA binding of multiple SOX family HMG-box fragments with IC50 values of 200-300 μM, showing a slight preference for SOX18 and SOX15[1].
Sm4 (24 h) inhibits SOX18-dependent Vcam-1 promoter transcriptional activity in COS-7 cells with an IC50 of 5.2 μM, with a CC50 of 117 μM[1].
Sm4 alters SOX18 chromatin binding dynamics in live cells, increasing the specific bound fraction and dwell time of specifically bound SOX18 in a concentration-dependent manner[1].
Sm4 (25 μM) can selectively dysregulate SOX18-mediated transcription in human umbilical vein endothelial cells (HUVECs)[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.

  • Protocol 1

    Solubility: ≥ 1.25 mg/mL (4.28 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

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.
