| WEHI-539, has high affinity (subnanomolar) and selectivity for BCL-XL and potently kills cells by selectively antagonizing its prosurvival activity. WEHI-539 has a high affinity for BCL-XL (IC50 = 1.1 nM). | ||||||
| Targets | BCL-XL | |||||
| IC50 | 1.1 nM | |||||
| 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. |

WEHI-539 is a small-molecule inhibitor of BCL XLwith an IC50 value of 1.1 nM [1].
WEHI-539 was designed as a BCL-XLinhibitor with high affinity. It interacted the with the binding groove of BCL-XLwith a 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 cand caspase-3 processing. In BCL-XLoverexpressed 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-539can not kill MEF cells lacking BAK because the cell death mediator BAK is regulated by BCL-XLand MCL-1. [1].
