SMILES: CN1CCC2=CC3=C(C(=C2[C@@H]1[C@@H]4C5=C(C(=C(C=C5)OC)OC)C(=O)O4)OC)OCO3

IUPAC name: (3S)-6,7-dimethoxy-3-[(5R)-4-methoxy-6-methyl-7,8-dihydro-5H-[1,3]dioxolo[4,5-g]isoquinolin-5-yl]-3H-2-benzofuran-1-one

ChEBI definition: A benzylisoquinoline alkaloid that is 1,2,3,4-tetrahydroisoquinoline which is substituted by a 4,5-dimethoxy-3-oxo-1,3-dihydro-2-benzofuran-1-yl group at position 1, a methylenedioxy group at positions 6-7 and a methoxy group at position 8. Obtained from plants of the Papaveraceae family, it lacks significant painkilling properties and is primarily used for its antitussive (cough-suppressing) effects.

Pharmacological roles (ChEBI): antitussive, antineoplastic agent, apoptosis inducer.

Other ChEBI roles (chemical / environmental): plant metabolite.

Parent form; salt/anhydrous children: CHEMBL2106732

Patent coverage: 4,032 distinct patent families (14,987 SureChEMBL compound mentions), from 2 matched compound structure(s). One matched structure accounts for 14,756 (98%) 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.

Pharmacology

Pharmacogenomics

No CPIC/DPWG dosing guideline, but PharmGKB curates 0 clinical and 1 variant annotation(s) for this drug (gene-keyed; see PharmGKB).

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.
