CHEBI:64977 EXACT SEEDED
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REVIEWED records curator sign-off on identity, structure, filing class and producer claims; DEPRECATED retains a superseded or out-of-scope record.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.
A member of the class of isoindoles that is 6-hydroxy-4-methoxy-5-methyl-2,3-dihydro-1H-isoindol-1-one which is substituted at position 4, 5, and 6 by methoxy, methyl, and hydroxy groups, respectively. A secondary metabolite found in Aspergillus silvativus, Aspergillus nidulans and Alternaria cichorii, it is poisonous to Russian knapweed (Acroptilon repens).

Filing pathway
Alkaloids — 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 1
A claim that this taxon makes the compound. The basis says what the evidence addressed — a knockout and a database assertion are not the same claim.
| Taxon | Basis | Cluster | Evidence |

| Aspergillus nidulans FGSC A4 NCBITaxon:227321 |
SOURCE_ASSERTION | mibig:BGC0000037 | PMID:22510154 |
Occurrences 6
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.
