Biological Activity

EGFR Inhibitor is a cell-permeable, 4,6-disubstituted pyrimidine compound that acts as a potent inhibitor of epidermal growth factor receptor (EGFR) kinase. By targeting EGFR, it disrupts receptor tyrosine kinase signaling and downstream cascades, while directly depolymerizing microtubules to impair cytoskeletal organization. Consequently, this chemical probe inhibits downstream cell proliferation and microtubule dynamics in target cellular 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).
