Biological Activity

Description Dequalinium Chloride is a PKC inhibitor with IC50 of 7-18 μM, and also a selective blocker of apamin-sensitive K+ channels with IC50 of 1.1 μM.

7 μM-18 μM
In vitro

Dequalinium chloride (DECA) is a cationic, lipophilic compound with structure similar to the dye rhodamine 123. DECA is selectively accumulated and retained within the mitochondria of carcinoma cells where it acts as a mitochondrial poison by blocking mitochondrial enzymes which can then disrupt cellular energy production, eventually resulting in cell death. Dequalinium Chloride is a blocker of ganglionic transmission (EC50 = 2 μM). [1] Dequalinium is a potent inhibitor of apamin-sensitive K+ channels in hepatocytes and of nicotinic responses in skeletal muscle. Dequalinium blocks angiotensin II-evoked K+ loss with an IC50 of 1.5 μM and also inhibited125I - monoiodoapamin binding with Ki of 1.1 μM. [2] Dequalinium produces a rapid and reversible inhibition of the slow apamin-sensitive component of the afterhyperpolarization (AHP) which follows a single action potential in cultured rat sympathetic neurones. [3] Dequalinium Chloride (DECA) is a dicationic lipophilic PKC inhibitor. When exposed to UV light, DECA covalently binds to and irreversibly inhibits PKCα and PKCβ. [4]

Molarity Calculator

Molarity Calculator

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).

Dilution Calculator

Dilution Calculator

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 )

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.
