S-63845

Research use only, not for human use.

S-63845 (S63845) is a highly potent, selective Mcl-1 inhibitor with Kd of 0.19 nM.

S-63845 (S63845) is a highly potent, selective Mcl-1 inhibitor with Kd of 0.19 nM, with no appreciable binding affinity to BCL-2 or BCL-XL (Ki>10 uM); binds to the BH3-binding groove of Mcl-1, potently kills MCL1-dependent cancer cells, including multiple myeloma (IC50<0.1 uM), leukaemia and lymphoma cells, by activating the BAX/BAK-dependent mitochondrial apoptotic pathway; is well tolerated and shopws high effectivity against mouse cancer models.Blood Cancer Preclinical.

The pro-survival protein myeloid cell leukemia 1 (MCL1) is over expressed in many cancers. S63845 is a small molecule that specifically binds with high affinity to the BH3-binding groove of MCL1. S63845 potently kills MCL1-dependent cancer cells, including multiple myeloma, leukaemia and lymphoma cells, by activating the BAX/BAK-dependent mitochondrial apoptotic pathway. The activity of S63845 is next evaluated in a panel of eight AML cell lines: all lines are sensitive to S63845 (IC50=4-233 nM).

S63845 shows potent anti-tumour activity with an acceptable safety margin as a single agent in several cancers. Intravenously injected (i.v.) S63845 exerts dose-dependent anti-tumour activity in human multiple myeloma (H929 and AMO1) xenografts in immunocompromised mice, with maximal tumour growth inhibition of 114% in the AMO1 model and 103% in the H929 model. At 25 mg/kg, S63845 induces complete regression in 7 out of 8 of the mice at 100 days after treatment in the AMO1 model.
