Biological Activity

Inhibitor of TCF/β-catenin-mediated transcription. Selectively inhibits β-catenin/CBP interaction; displays no effect on β-catenin/p300 interaction. Exhibits growth inhibitory effects in colon carcinoma cell lines (SW480 and HCT-116 cells); also displays efficacy in Min mouse and nude mouse SW620 xenograft models.

Preparing Stock Solutions

The following data is based on the product molecular weight 548.63. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 1.82 mL 9.11 mL 18.23 mL
5 mM 0.36 mL 1.82 mL 3.65 mL
10 mM 0.18 mL 0.91 mL 1.82 mL
50 mM 0.04 mL 0.18 mL 0.36 mL
