dihydrostemphyloxin I
CHEBI:145071 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REVIEWED records curator sign-off on identity, structure, filing class and producer claims; DEPRECATED retains a superseded or out-of-scope record.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.
An octahydronaphthalene that is stemphyloxin I in which the C=C bond of the enol moiety has been reduced to a C‒C bond.

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.

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.

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.

Open questions 1
name-disagreement — ChEBI calls this structure 'dihydrostemphyloxin I' and MIBiG calls it 'compound 9'. They share a Standard InChIKey, so if the names denote different compounds then one upstream record has the wrong structure. Check which.
