What these status tags mean
Curation status describes a workflow state. SEEDED means the record entered through the source-seeding workflow; it does not imply that no later curation occurred. PROPOSED marks an addition awaiting review; REVIEWED records curator sign-off on identity, structure, filing class and producer claims; DEPRECATED retains a superseded or out-of-scope record. These are workflow decisions, not independently verified human review. Agent-assisted contributions may appear in the record history.
Grounding describes the identifier mapping: EXACT uses an ontology identity asserted by the source; MINTED keeps a local identifier when no defensible ontology identity is available; REVIEW_NEEDED flags an exact structure whose ontology identity needs adjudication. The grounding note retains any unresolved alternatives. These tags do not establish the strength of producer or activity evidence.
Structure
| Standard InChIKey | AQEGYTZKJNBFQS-KIMWIMGTSA-N |
|---|---|
| SMILES | NC(=O)\C=C\C=C\C1C=CC2C=CC3OC(\C=C\C=C\C=C\C(O)=O)C1C23 |
| Stereochemistry | undefined stereocentres — the InChIKey does not distinguish this compound from its stereoisomers |
Filing pathway
Polyketides — computed by NPClassifier npclassifier.gnps2.org@2026-09-07, which is why it is pinned rather than recomputed. The gene cluster's asserted class is pks, from MIBiG.
Producer organisms 0
None. The compound has a characterized gene cluster whose host NCBI does not name, which for an uncultured symbiont is the honest state — see the discussion below.
Occurrences 1
Somebody found the compound in this organism and cited it. That is not a claim that the organism makes it, and nothing here promotes one to the other.

A locus claim and a taxon claim are different questions. Heterologous expression settles the first and leaves the second where the isolation report left it.

unnamed-producer — No producer claim is written from BGC0001369, which gives NCBITaxon:77133 (uncultured bacterium — shared by every unplaced bacterium), because the taxon names no single organism. The cluster is kept: a characterized locus is an origin assertion whether or not its host has a name, and for a compound from an uncultured symbiont that is the honest state. Name the producer if the primary literature does.
