Ordering Information

Biological Activity

PS-48 is a selective, small-molecule allosteric activator of phosphoinositide-dependent protein kinase-1 (PDK1) that targets the regulatory PIF-binding pocket. By binding to this allosteric site, PS-48 stimulates PDK1 kinase activity independently of phosphoinositide binding. This selective activation promotes downstream phosphorylation and activation of target kinases within the PI3K/AKT pathway, driving cellular signaling and survival. [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).
