Description

WEHI-539 hydrochloride is a small-molecule inhibitor of BCL XL with IC50 value of 1.1 nM [1].

WEHI-539 was designed as a BCL-XL inhibitor with high affinity. It interacted with the binding groove of BCL-XL with Kd value of 0.6 nM. In MEF cells lacking MCL-1, WEHI-539 induced apoptosis which was evidenced by the release of mitochondrial cytochrome c and caspase-3 processing. In BCL-XL overexpressed MEF cells, WEHI-539 showed EC50 value of 0.48 μM. WEHI-539 also significantly induced apoptosis of the platelets purified from mice. Besides that, WEHI-539 cannot kill MEF cells lacking BAK because the cell death mediator BAK is regulated by BCL-XL and MCL-1. [1].

Cell experiment[1]:

Cell lines

Human colon cancer cell

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.

Reaction Conditions

1 μM, 24h

Applications

Limiting dilution analysis with CSCs that were pre-treated with ABT-737, ABT-199 or WEHI-539 revealed that ABT-737 and WEHI-539 both were sufficient to decrease clonogenic capacity, whereas ABT-199 did not affect clonogenic growth. As WEHI-539 is selective for BCLXL, this points to a dependency of CSCs on BCLXL for survival. Importantly, ABT-737- or WEHI-539-induced loss of clonogenicity could be restored when BCLXL was ectopically overexpressed. When spheroid cultures were treated with ABT-737 or WEHI-539 compounds, CSCs were effectively sensitized toward oxaliplatin and other chemotherapeutic agents.

Conseils généraux
Choisissez un solvant adapté selon les données de solubilité du produit. Après préparation, répartissez la solution mère en aliquotes afin d’éviter les cycles répétés de congélation-décongélation.
Utilisez les solutions mères dans les 6 mois si elles sont conservées à -80°C, ou dans le mois si elles sont conservées à -20°C.
Pour améliorer la solubilité, réchauffez le tube à 37°C et soniquez-le pendant une durée appropriée.
Conditions d’expédition
Les échantillons d’évaluation sont expédiés avec des blocs réfrigérants. Les autres formats sont expédiés à température ambiante ou, sur demande, avec des blocs réfrigérants.
