ICG-001 (OP-724, PRI-724, CBP-beta catenin inhibitor) antagonizes Wnt/β-catenin/TCF-mediated transcription and specifically binds to CREB-binding protein (CBP) with IC50 of 3 μM, but is not the related transcriptional coactivator p300. ICG-001 induces apoptosis.

|Description||ICG-001 (OP-724, PRI-724, CBP-beta catenin inhibitor) antagonizes Wnt/β-catenin/TCF-mediated transcription and specifically binds to CREB-binding protein (CBP) with IC50 of 3 μM, but is not the related transcriptional coactivator p300. ICG-001 induces apoptosis.|
ICG-001 has no effect on the related reporter construct, FOPFLASH, which contains mutated TCF sites. After treatment with 25μM of ICG-001 for 8 hours, SW480 cell reduces the steady-state levels of Survivin and Cyclin D1 RNA and protein, both of which can be up-regulated by β-catenin. ICG-001 selectively induces apoptosis in transformed cells but not in normal colon cells, reduces in vitro growth of colon carcinoma cells.  ICG-001, can phenotypically rescue normal nerve growth factor (NGF) -induced neuronal differentiation and neurite outgrowth in the presenilin-1 mutant cells, emphasizing the importance of the TCF/β-catenin signaling pathway on neurite outgrowth and neuronal differentiation.  A recent study demonstrates that 5μM ICG-001 inhibits leptin-induced EMT, invasion and tumorsphere formation in MCF7 cells. 
|In vivo||Administration of a water-soluble analog of ICG-001 for 9 weeks reduces the formation of colon and small intestinal polyps by 42% as effectively as the nonsteroidal antiinflammatory agent Sulindac, which has consistently demonstrated efficacy in this model. No overt toxicity is detected throughout the course of treatment. In the SW620 nude mouse xenograft model of tumor regression, 150 mg/kg, i.v. of analog demonstrates a dramatic reduction in tumor volume over the 19-day course of treatment, with no mortality or weight loss.  ICG-001 (5 mg/kg per day) significantly inhibits beta-catenin signaling and attenuates bleomycin-induced lung fibrosis in mice, while concurrently preserving the epithelium. |
DUAL-Luciferase Reporter Assay:The Dual-Luciferase Reporter (DLR) Assay System provides an efficient means of performing dual reporter assays. In the DLRTM Assay, the activities of firefly (Photinus pyralis) and Renilla (Renilla reniformis, also known as sea pansy) luciferases are measured sequentially from a single sample. The firefly luciferase reporter is measured first by adding Luciferase Assay Reagent II (LAR II) to generate a “glow-type” luminescent signal. After quantifying the firefly luminescence, this reaction is quenched, and the Renilla luciferase reaction is initiated by simultaneously adding Stop & Glo® Reagent to the same tube. The Stop & Glo® Reagent also produces a “glow-type” signal from the Renilla luciferase, which decays slowly over the course of the measurement. In the DLRTM Assay System, both reporters yield linear assays with subattomole (<10-18) sensitivities and no endogenous activity of either reporter in the experimental host cells. Furthermore, the integrated format of the DLRTM Assay provides rapid quantitation of both reporters either in transfected cells or in cell-free transcription/translation reactions.
|In vitro||DMSO||100 mg/mL (182.27 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+50% PEG 300+5% Tween 80+ddH2O
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Frequently Asked Questions
If the compound is stored in DMSO at -80, how long would it be stable? For cell culture, how long should I change for the fresh medium with ICG-001?
The product in DMSO solution can be stored at 4 degree for 1 week and -20 degree for 1 month. The best storage condition is solid powder, even at -80 the solution is not stable enough for long term storage. For cell culture, you need change medium every 48h.
