SMILES: C1=CC=C(C=C1)NC(=O)CCCCCCC(=O)NO

IUPAC name: N’-hydroxy-N-phenyloctanediamide

ChEBI definition: A dicarboxylic acid diamide comprising suberic (octanedioic) acid coupled to aniline and hydroxylamine. A histone deacetylase inhibitor, it is marketed under the name Zolinza for the treatment of cutaneous T cell lymphoma (CTCL).

Pharmacological roles (ChEBI): EC 3.5.1.98 (histone deacetylase) inhibitor, apoptosis inducer, antineoplastic agent.

Also known as: MK-0683, MK0683, NSC-701852, NSC-748799, NSC-759852, Suberoylanilide hydroxamic acid, Vorinostat, Zolinza, suberoylanilide hydroxamic acid, suberoylanilidehydroxamic acid, vorinostat, Suberoylanilidehydroxamic acid

Patent coverage: 13,959 distinct patent families (50,361 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 CPIC/DPWG dosing guideline or drug-level clinical/variant annotations in PharmGKB for this molecule.

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.
