SMILES: CC(C)CN1C=NC2=C1C3=CC=CC=C3N=C2N

IUPAC name: 1-(2-methylpropyl)imidazo[4,5-c]quinolin-4-amine

ChEBI definition: An imidazoquinoline fused [4,5-c] carrying isobutyl and amino substituents at N-1 and C-4 respectively. A prescription medication, it acts as an immune response modifier and is used to treat genital warts, superficial basal cell carcinoma, and actinic keratosis.

Pharmacological roles (ChEBI): antineoplastic agent, interferon inducer.

Also known as: Aldara, Imiquimod, NSC-369100, NSC-759651, R-837, S-26308, S26308, Tmx-101, Zartra, Zyclara, imiquimod, SID865810

Patent coverage: 14,352 distinct patent families (56,604 SureChEMBL compound mentions), from 2 matched compound structure(s). One matched structure accounts for 55,317 (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 1 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.
