Mechanism of Action

Targets/IC₅₀/Ki	human MCL-1 0.19 nM(Kd)
In vitro	S63845 induces death of cancer cell lines with known reliance on MCL-1, displaying classical hallmarks of apoptosis that are dependent on caspases and BAX/BAK-mediated mitochondrial outer membrane permeabilisation. It has a 6 fold higher affinity for human MCL-1 over mouse MCL-1. This compound is effective against haematological cancer-derived cell lines in vitro and in vivo and also AML samples, but does not readily kill normal human haematopoietic progenitor cells.
In vivo	In vivo, S63845 shows potent anti-tumour activity with an acceptable safety margin as a single agent in several cancers. This compound is well tolerated by the mice with no significant weight loss observed. Some of solid tumour models shows sensitivity to this compound monotherapy, while many others are only killed when treated with a combination of this compound and inhibitors of oncogenic kinases.
