Biological Activity
STF-118804 is a highly specific inhibitor of nicotinamide phosphoribosyltransferase (NAMPT), a key rate-limiting enzyme in the NAD+ salvage pathway. Inhibition of NAMPT leads to intracellular NAD+ depletion, resulting in impairment of ATP synthesis and downstream activation of apoptotic pathways in target cells. Consequently, this target blockade suppresses cellular viability and metabolic function across cancer cell lines reliant on NAD+ salvage biosynthesis. [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).
Pre-aliquoted for Longevity: Solid-state aliquots offer longer shelf life compared to stock solutions.
