SMILES: C1CN2C(=CC=C2C(=O)C3=CC=CC=C3)C1C(=O)O
IUPAC name: 5-benzoyl-2,3-dihydro-1H-pyrrolizine-1-carboxylic acid
ChEBI definition: A racemate comprising equimolar amounts of (R)-(+)- and (S)-(−)-5-benzoyl-2,3-dihydro-1H-pyrrolizine-1-carboxylic acid. While only the (S)-(−) enantiomer is a COX1 and COX2 inhibitor, the (R)-(+) enantiomer exhibits potent analgesic activity. A non-steroidal anti-inflammatory drug, ketorolac is mainly used (generally as the tromethamine salt) for its potent analgesic properties in the short-term management of post-operative pain, and in eye drops to relieve the ocular itching associated with seasonal allergic conjunctivitis. It was withdrawn from the market in many countries in 1993 following association with haemorrhage and renal failure.
Pharmacological roles (ChEBI): cyclooxygenase 2 inhibitor, cyclooxygenase 1 inhibitor, non-steroidal anti-inflammatory drug, analgesic.

Patent coverage: 13,219 distinct patent families (53,920 SureChEMBL compound mentions), from 1 matched compound structure(s). 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.
