ilicicolin H

CHEBI:77772 EXACT SEEDED antifungalantimicrobial unspecifiedcytotoxicenzyme inhibitor

An aromatic ketone in which the ketone carbonyl group is attached to a (1R,2R,4aS,7S,8aR)-4,7-dimethyl-1-[(1E)-prop-1-en-1-yl]-1,2,4a,5,6,7,8,8a-octahydronaphthalen-2-yl group and a 4-hydroxy-5-(4-hydroxyphenyl)-2-oxo-1,2-dihydropyridin-3-yl group. Isolated from the from the "imperfect" fungus Cylindrocladium iliciola strain MFC-870.

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 nrps, pks, from MIBiG.

Producer organisms 2

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.
