SMILES: CCCCOC1=CC=C(C=C1)CC(=O)NO

IUPAC name: 2-(4-butoxyphenyl)-N-hydroxyacetamide

ChEBI definition: A hydroxamic acid derived from phenylacetamide in which the benzene moiety is substituted at C-4 by a butoxy group. It has anti-inflammatory, analgesic, and antipyretic properties.

Pharmacological roles (ChEBI): non-narcotic analgesic, non-steroidal anti-inflammatory drug, antipyretic.

Also known as: Bufexamac, Bufexamaco, CP 1044 J3, Duradermal, NSC-758153, Parfenac, SID11112517, SID26746938, SID855633, SID56422414, SID124882428, SID124882430

Patent coverage: 1,839 distinct patent families (6,619 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.

Pharmacology

Pharmacogenomics

No PharmGKB pharmacogenomic data curated for this drug.

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.
