Ordering Information

Biological Activity

Z218484536 is a selective and brain-penetrant inhibitor of phosphoserine phosphatase (PSPH), a key enzyme in the L-serine biosynthesis pathway. Inhibition of PSPH blocks the enzymatic conversion of O-phospho-L-serine to L-serine, thereby suppressing de novo serine biosynthesis and disrupting downstream metabolic networks. This targeted blockade depletes essential biological precursors required for nucleotide synthesis and cellular homeostasis, ultimately impairing cancer cell survival and proliferation. [1]

FAQ
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).
