About this product
Product information from the supplier.
DC661 (CAS NO. 1872387-43-3) is a high-potency pharmacological probe and selective inhibitor of palmitoyl-protein thioesterase 1 (PPT1) and PPT2. Designed for advanced oncology and cell biology research, this dimeric chloroquine derivative effectively disrupts lysosomal function and inhibits autophagic flux, making it an indispensable tool for investigating nutrient recycling and organelle clearance in malignant cells.
By neutralizing lysosomal pH and blocking the fusion of autophagosomes with lysosomes, DC661 triggers the accumulation of LC3B-II markers and induces apoptotic cell death. It is particularly effective in overcoming resistance to targeted therapies, such as BRAF/MEK inhibitors in melanoma, pancreatic, and colorectal carcinomas, providing researchers with a superior alternative to traditional agents like hydroxychloroquine.

Frequently Asked Questions
Q: What is the primary application of DC661 in pharmaceutical research?
DC661 is primarily used as a pharmacological probe to study autophagy dependence in malignant cells, specifically for overcoming resistance to targeted therapies in melanoma and colorectal cancer research.
Q: How does DC661 differ from standard Hydroxychloroquine (HCQ)?
DC661 is significantly more potent, inhibiting autophagic flux at concentrations 100 times lower than HCQ and demonstrating superior efficacy in reducing cancer cell viability.
Q: What are the recommended storage conditions for this API?
For maximum stability, DC661 should be stored at -20°C, protected from light and moisture, in a tightly sealed container.
Q: Can DC661 be used for clinical human trials?
No, this compound is indicated strictly for non-clinical, in vitro, and in vivo research applications only.
Q: What quality certifications accompany the DC661 shipments?
Every batch comes with a Certificate of Analysis (COA), RP-HPLC purity reports, and mass spectrometry (MS) chromatograms to ensure pharmaceutical-grade quality.
Q: Which solvent is best for dissolving DC661?
DC661 is soluble in DMSO (at concentrations >10 mg/mL) and DMF, but it is insoluble in water.
