S63845 is a selective MCL-1 inhibitor (Kd = with no discernible binding to BCL-2 or BCL-XL. By specifically binding the BH3-binding groove of MCL-1, it disrupts anti-apoptotic signaling and restores pro-apoptotic BAK/BAX activity. This blockade triggers cytochrome c release and caspase activation, leading to the selective induction of apoptosis in MCL-1-dependent hematological and solid tumor cells. [1]

Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
