|Description||DC661 is capable of deacidifying the lysosome and inhibiting autophagy significantly better than hydroxychloroquine (HCQ).|
Treatment of melanoma cells with DC661 results in a more striking accumulation of the autophagic vesicle marker LC3B-II at lower concentrations compared with either Lys05 or HCQ, reflecting more pronounced accumulation of autophagic vesicles at concentrations between 0.1 and 10 μmol/L. All cells die at concentrations above 10 μmol/L for DC661 in contrast to Lys05 and HCQ. Compared with HCQ or Lys05, DC661 treatment induces a significantly more potent inhibition of autophagic flux in melanoma cells expressing the mCherry-eGFP-LC3B reporter, and significantly higher levels of free GFP in melanoma cells expressing GFP-LC3B. DC661 treatment resulted in significantly greater lysosomal deacidification compared with either HCQ or Lys05. The IC50 of DC661 in 72-hour MTT assays is 100-fold lower than that of HCQ across multiple cancer cell lines including colon and pancreas cancer cell lines. DC661 suppresses long-term clonogenic growth of melanoma cells more effectively and induces significantly more apoptosis than Lys05, HCQ, or combined BRAF and MEK inhibition in BRAF-mutant melanoma cells.
Treatment with the reduced dose (3 mg/kg, i.p.) of DC661 in a HT29 xenograft results in a significant reduction in tumor volume and almost complete suppression of daily tumor growth rate compared with control mice without significantly affecting mouse weight.

* 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.
