SMILES: CCCCC[C@@H](/C=C/[C@H]1[C@@H](C[C@@H]([C@@H]1C/C=C\CCCC(=O)O)O)O)O

IUPAC name: (Z)-7-[(1R,2R,3R,5S)-3,5-dihydroxy-2-[(E,3S)-3-hydroxyoct-1-enyl]cyclopentyl]hept-5-enoic acid

ChEBI definition: A prostaglandins Fα that is prosta-5,13-dien-1-oic acid substituted by hydroxy groups at positions 9, 11 and 15. It is a naturally occurring prostaglandin used to induce labor.

Other ChEBI roles (chemical / environmental): human metabolite, mouse metabolite.

Also known as: Dinoprost, Pgf2.alpha., Pgf2a, Pgf2alpha, Prosmon, Prostaglandin f2.alpha., Prostaglandin f2alpha, U-14,583, U-14583, SID29216066, Prostaglandin F2a, Prostaglandin F2alpha

Parent form; salt/anhydrous children: CHEMBL1200896

Patent coverage: 1,264 distinct patent families (3,118 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.

314 molecules share ≥1 primary target. Top 60 by shared-target count:
