  • Effects of AVL-292, CNX-774 and dasatinib on IgE-mediated histamine release in human basophils. Basophils (BA) obtained from three nonallergic donors (A), three patients allergic to Der p 2, and three patients allergic to Phl p 5 (B and C) were preincubated in control medium (Co) or medium containing various concentrations of AVL-292, CNX-774, or dasatinib (0.001-1 μmol/L) at 37°C for 30 minutes. Then, cells were exposed to anti-IgE antibody E-124.2.8 (1 μg/mL; nonallergic donors) or recombinant allergens (1 μg/mL of rDer p 2 or rPhl p 5 in allergic patients) at 37°C for 30 minutes. After centrifugation, histamine concentrations were determined in cell-free supernatants and cell lysates. Histamine release is expressed as percentage of total histamine. Results show the percentage of control and represent mean SD from three independent experiments (three donors). Asterisk (*): P<0.05 by Student's t test with Bonferroni correction

Biological Activity

Description CNX-774 is an irreversible, orally active, and highly selective BTK inhibitor with IC50 of <1 nM.
Features Orally bioavailable BTK-selective inhibitor, binding covalently to target protein.
BTK [1]
<1 nM
In vitro

In cellular assays, CNX-774 demonstrates potent inhibitory activity towards BTK with IC50 of 1-10 nM by targeting Cys-481 residue within the ATP binding site of the enzyme. [1]


Solubility (25°C)

In vitro DMSO 100 mg/mL (200.2 mM)
Ethanol 2 mg/mL (4.0 mM)
Water Insoluble

* 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.

Bio Calculators

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)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / 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 )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / 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.
