GW406108X is a synthetic small-molecule inhibitor targeting Kif15 (Kinesin-12) and unc-51 like autophagy activating kinase 1 (ULK1). By selectively impairing ULK1 kinase function, GW406108X effectively blocks cellular autophagy pathways downstream without disrupting upstream AMPK or mTORC1 signaling cascades. This targeted inhibition suppresses autophagic flux in cell-based models, providing a useful pharmacological tool to study kinesin motor dynamics and autophagy regulation. [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).
