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)[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (3.01 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
10 mM HEPES pH 7.4, 175 mM NaCl, 25 μM EDTA, 1 mM TCEP, 0.01% P20 and 1% DMSO is used as a running buffer. The ligand surface is generated using double His-tagged proteins. Serial dilutions of the compound in buffer are injected over the protein surface. All sample measurements are performed at a flow rate of 30 μL per min (injection time 120 s, dissociation time 360 s). The sensor surface is regenerated by consecutive injections of 0.35 M EDTA pH 8.0 with 0.1 mg/mL trypsin, 0.5 M imidazole and 45% DMSO (60 s, 15 μL per min)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Cells are treated with increasing doses of S63845 (typically 0.008, 0.025, 0.04, 0.2, 1, 5 μM) for 24 h. Cells are stained with Annexin V-FITC and propidium iodide, analysed on a FACS Calibur and live cells are recorded. Data are presented as per cent cell death induction relative to cells cultured in medium alone[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice: S63845 is formulated extemporaneously in 25 mM HCl, 20% 2-hydroxy propyl β -cyclo dextrin 20% and administrated at the 6.25, 12.5, 25 mg/kg for 0, 20, 40, 60, 80 days. Tumour growth inhibition (TGImax) is calculated[1].
