Compound class: Synthetic organic
Comment: The chemical structure for zipalertinib was revealed in WHO proposed INN list 126 (Jan 2022), in which it was described as a tyrosine kinase inhibitor and antineoplastic agent. Its SMILES matches it to the EGFR inhibitor TAS-6417 (now re-coded as CLN-081) [1] via PubChem. TAS-6417 was designed to selectively target EGFR with exon 20 insertion mutations, which are well defined drivers of non-small cell lung cancer. It is an orally available compound.
