harziphilone

CHEBI:66006 EXACT SEEDED antiviral

A member of the class of isochromanes that is 1,5,6,7-tetrahydro-8H-isochromen-8-one substituted by hydroxy groups at positions 6 and 7, a methyl group at position 7 and a penta-1,3-dien-1-yl moiety at position 3. Isolated from the fermentation broth of Trichoderma harzianum, it exhibits anti-HIV activity.

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.
