Ordering Information

Biological Activity

VPS34 inhibitor 1 is a potent and selective inhibitor of vacuolar protein sorting 34 (VPS34), a class III phosphoinositide 3-kinase. By targeting VPS34 activity, it suppresses the synthesis of phosphatidylinositol 3-phosphate, thereby disrupting autophagosome formation and endosomal membrane trafficking. Blockade of this lipid kinase pathway inhibits autophagic flux and alters endolysosomal dynamics, leading to impaired cellular vesicle transport and altered degradation processes.

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).
