IUPAC name: 2-acetyloxybenzoic acid
ChEBI definition: A member of the class of benzoic acids that is salicylic acid in which the hydrogen that is attached to the phenolic hydroxy group has been replaced by an acetoxy group. A non-steroidal anti-inflammatory drug with cyclooxygenase inhibitor activity.
Pharmacological roles (ChEBI): non-steroidal anti-inflammatory drug, non-narcotic analgesic, platelet aggregation inhibitor, antipyretic, cyclooxygenase 2 inhibitor, cyclooxygenase 1 inhibitor, prostaglandin antagonist, teratogenic agent, anticoagulant, EC 1.1.1.188 (prostaglandin-F synthase) inhibitor, drug allergen, geroprotector.
Other ChEBI roles (chemical / environmental): plant activator.

Parent form; salt/anhydrous children: CHEMBL1697753, CHEMBL2296002
Patent coverage: 238,647 distinct patent families (694,602 SureChEMBL compound mentions), from 2 matched compound structure(s). One matched structure accounts for 692,813 (100%) 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.
