Product Data Sheet
STX-721
Catalog No. A28549
STX-721 is an orally active, irreversible covalent inhibitor of the EGFR exon 20 insertion (ex20ins) mutants, specifically targeting their unique dynamic protein states. This compound effectively inhibits the kinase activity of ex20ins mutants, such as NPG, ASV, and SVD, leading to a reduction in phosphorylation of EGFR and downstream ERK signaling. In cellular assays, STX-721 suppresses the proliferation of ex20ins-mutant Ba/F3 cells and human non-small cell lung cancer (NSCLC) cell lines. Additionally, it demonstrates tumor regression in patient-derived xenograft models, making it a valuable tool for studying NSCLC with EGFR or HER2 ex20ins mutations.
