CHEBI:156298 EXACT SEEDED antifungal

A polyketide that is 2,3-dihydrofuran substituted by hydroxy, methyl, oxo, methyl and (2S,3Z,5E,7R,8R,9E)-2,8-dihydroxy-7,9,12-trimethyltrideca-3,5,9-trien-1-yl groups at positions 2, 2, 3, 4, and 5, respectively. It is a cytotoxic natural product found in several myxobacteria species and inhibits the growth of some filamentous fungi.

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.

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.
