Biological Activity

Description CNX-2006 is a novel irreversible mutant-selective EGFR inhibitor with IC50 of < 20 nM, with very weak inhibition at wild-type EGFR.
mutant EGFR [1]
<20 nM
In vitro

CNX-2006 is a novel irreversible EGFR tyrosine kinase inhibitor, specifically inhibits activating mutations of EGFR as well as the T790M mutation while having very weak inhibition at wild-type EGFR. In in vitro modeling of acquired resistance, continuous CNX-2006 treatment on drug-sensitive EGFR mutant cells leads to resistance more slowly than erlotinib. Dose escalation with CNX-2006 leads to differential effects in different lines, but does not select for T790M-mediated resistance. [1]CNX-2006 resistent cells shows increased expression of EMT markers and MMP9.[2]

In vivo CNX-2006 is effective in H1975 (EGFR L858R/T790M) xenograft model. [1] [2]

*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.
