ochrindole A
CHEBI:167043 EXACT SEEDED antibacterial
A bisindole alkaloid that is phenol bearing a 3,3-dimethylallyl group at position 4, two methoxy groups at positions 3 and 6, and two indol-3-yl groups at positions 2 and 5. It is a natural product isolated from the sclerotia of Aspergillus orbraceus, with moderate activity against some insects, as well as Gram-positive bacteria.

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.

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.
