Ordering Information

Biological Activity

Zipalertinib (TAS6417) is a selective, wild-type-sparing EGFR inhibitor that potently targets EGFR exon 20 insertion mutations with IC50 values ranging from 1.1 to 8.0 nmol/L. By suppressing mutant EGFR kinase activity, zipalertinib inhibits downstream auto-phosphorylation and blocks activation of AKT and ERK signaling pathways. This pathway blockade inhibits cell proliferation and induces apoptosis in non-small cell lung cancer models expressing EGFR exon 20 insertion mutations. [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).
