CHEBI:156318 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REVIEWED records curator sign-off on identity, structure, filing class and producer claims; DEPRECATED retains a superseded or out-of-scope record.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 2-pyranones that is 2H-pyran-2-one in which the hydrogens at positions 3, 4, 5 and 6 are replaced by methyl, hydroxy, methyl and (4E,6E,12E)-4,6,8,12,14-pentamethylhexadeca-4,6,12-trien-2-yl groups, respectively. It is a decaketide that is anabolized by a type I polyketide synthase in Alternaria solani.

| SMILES | CCC(C)/C=C(\C)/CCCC(C)/C=C(\C)/C=C(\C)/CC(C)C1=C(C(=C(C(=O)O1)C)O)C |
| 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 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.

Occurrences 2
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.
