Ordering Information

Biological Activity

Perifosine is an oral alkylphospholipid that acts as an Akt inhibitor by targeting the pleckstrin homology domain of Akt. By interacting with cellular membranes, perifosine modulates membrane permeability, lipid composition, and phospholipid metabolism. These membrane-targeted effects block downstream mitogenic signal transduction and inhibit anti-apoptotic MAPK signaling while modulating pro-apoptotic SAPK/JNK pathways, ultimately promoting cell differentiation, antiproliferative activity, and apoptosis in cancer cells.

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).
