DIMBOA
CHEBI:18048 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REVIEWED records curator sign-off on identity, structure, filing class and producer claims; DEPRECATED retains a superseded or out-of-scope record.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 lactol that is DIBOA in which the hydrogen at position 7 is replaced by a methoxy group. It has been isolated from the maize plants.
Structure
| Standard InChIKey | GDNZNIJPBQATCZ-UHFFFAOYSA-N |
|---|---|
| SMILES | COC1=CC2=C(C=C1)N(C(=O)C(O2)O)O |
| Stereochemistry | undefined stereocentres — the InChIKey does not distinguish this compound from its stereoisomers |
| Cross-references | pubchem:2358 |
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 other, 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.

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 'DIMBOA' and MIBiG calls it 'benzoxazinone DIMBOA'. They share a Standard InChIKey, so if the names denote different compounds then one upstream record has the wrong structure. Check which.
