IUPAC name: N-[(8S)-4-amino-6-methyl-5-quinolin-3-yl-8,9-dihydropyrimido[5,4-b]indolizin-8-yl]prop-2-enamide
ChEBI definition: A member of the class of acrylamides that is (8S)-6-methyl-5-(quinolin-3-yl)-8,9-dihydropyrimido[5,4-b]indolizine-4,8-diamine in which the amino group at position 8S is substituted by an acryloyl group. It a covalent epidermal growth factor receptor inhibitor that targets exon 20 insertion mutations.
Pharmacological roles (ChEBI): epidermal growth factor receptor antagonist, antineoplastic agent, apoptosis inducer.

Patent coverage: 123 distinct patent families (265 SureChEMBL compound mentions), from 4 matched compound structure(s). One matched structure accounts for 202 (76%) of the total. Mentions count patents naming the compound (not distinct inventions), so promiscuous / reference molecules inflate the mention figure — families are the dedup metric.

Molecules sharing ≥1 of this drug’s curated primary targets, merged from two biobtree sources and ranked by shared-target count, then clinical phase: ChEMBL clinical-stage candidates (development phase ≥2) and PubChem drug-class bioactivity (approved / known drugs acting on the target). Deduplicated by drug name; the drug’s own salt forms are excluded. Note: for a drug with few primary targets a shared-target match can reflect off-target / promiscuous binding rather than the same therapeutic mechanism — the phase ordering surfaces bona-fide therapeutics first.
