S63845 is a small molecule MCL1 inhibitor with Ki < 1.2 nM [1].

Myeloid cell leukemia 1 (MCL1) is a pro-survival protein and belongs to BCL-2 family proteins. BCL-2 family proteins are key regulators of the mitochondrial apoptotic pathway. MCL1 is overexpressed in many cancers, so inhibitors targeting this protein may kills MCL1-dependent cancer cells [1].

S63845 is a highly selective and potent MCL1 inhibitor. S63845 bound human MCL1 with KD value of 0.19 nM. S63845 was approximately 1,000-fold more potent in killing MCL1-dependent H929 multiple myeloma cells than MCL1 inhibitor A-1210477. S63845 also induced caspase-dependent phosphatidyl-serine exposure, PARP cleavage and cytochrome c release from mitochondria. In HeLa cells, S63845 disrupted binding of BAK and BAX to MCL1. S63845 killed cancer cells through activation of the BAX/BAK-dependent mitochondrial apoptotic pathway by direct inhibition of MCL1 [1].

In immunocompromised mice with human multiple myeloma (H929 and AMO1) xenografts, intravenously injected (i.v.) S63845 showed dose-dependent anti-tumour activity with maximal tumour growth inhibition (TGImax) of 103% and 114% in the H929 and AMO1 model, respectively [1].

Applications	S63845 is a small molecule MCL1 inhibitor with Ki <1.2 nM. S63845 is effective against haematological cancer-derived cell lines. S63845 potently killed MCL1-dependent H929 multiple myeloma cells. S63845 disrupted binding of BAK and BAX to MCL1 in HeLa cells. Treatment with S63845 increased MCL1 protein levels in the HCT-116 colon carcinoma cell line. In the tested myeloma cell lines, some were highly sensitive to S63845 (IC50 <0.1 μM), six lines were moderately sensitive (0.1 μM <IC50 <1 μM) and two lines were insensitive (IC50 >1 μM). In a panel of human lymphomas and chronic myeloid leukaemia 11 cell lines: five lines were highly sensitive to S63845 (IC50 <0.1 μM), three were moderately sensitive (0.1 μM <IC50 <1 μM) and three were insensitive to S63845 (IC50 >1 μM). In a panel of eight AML cell lines: all lines were sensitive to S63845 (IC50 4–233 nM) [1].
Animal experiment [1]:
Animal models	Human multiple myeloma (H929 and AMO1) xenografted mice
Dosage form	Intravenously injected (i.v.), 25 mg/kg
Application	Intravenously injected (i.v.) S63845 exerted dose-dependent anti-tumour activity in human multiple myeloma (H929 and AMO1) xenografts in immunocompromised mice, with maximal tumour growth inhibition (TGImax) of 114% in the AMO1 model and 103% in the H929 model. S63845 (25 mg/kg) induced complete regression in 7 out of 8 of the mice at 100 days after treatment in the AMO1 model. S63845 (i.v., 25 mg/kg, 5 days) cured 70% of immuno-competent C57BL/6 mice bearing Eμ-Myc mouse lymphomas, with no side-effects evident in normal tissues. S63845 (12.5 mg/kg) showed potent activity in the MV4-11 human AML xenograft model, with a TGImax of 86%. S63845 (25 mg/kg) resulted in completeremission in 6 out of 8 mice after 80 days.
Other notes	Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
