Biological Activity

KRAS-533 is a small-molecule KRAS agonist that targets the GTP/GDP-binding pocket of KRAS. By preventing GTP hydrolysis, KRAS-533 promotes the accumulation of active GTP-bound KRAS. This activation triggers apoptotic and autophagic cell death pathways, ultimately leading to the suppression of mutant KRAS lung cancer in both in vitro and animal models. [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).
