Biological Activity

Description S63845 is a new, selective MCL-1 inhibitor with the Kd value of 0.19 nM and has no discernible binding to the other BCL-2 members, BCL-2 or BCL-XL.
Targets
human MCL-1 [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[1]. S63845 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[2].
In vivo In vivo, S63845 shows potent anti-tumour activity with an acceptable safety margin as a single agent in several cancers. S63845 is well tolerated by the mice with no significant weight loss observed. Some of solid tumour models shows sensitivity to S63845 monotherapy, while many others are only killed when treated with a combination of S63845 and inhibitors of oncogenic kinases[2].

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    HeLa cells

  • Concentrations

    0.1, 0.3, 1, 3 μM

  • Incubation Time

    4 h

  • Method

    HeLa cells transduced with Flag–BCL-XL, Flag–BCL-2 or Flag–MCL1 expression constructs are treated for 4 h with increasing concentrations of S63845, before immunopreciptation using anti-FLAG antibody. Immunoprecipitates and total inputs are analysed by immunoblotting for the FLAG-tagged proteins as well as the associated BAK and BAX proteins.
Animal Study:

[2]
  • Animal Models

    C57BL/6 mice

  • Dosages

    25 mg/kg

  • Administration

    i.v.
