pyripyropene A
CHEBI:64695 EXACT SEEDED
A sesquiterpenoid that consists of (3S,4R,4aR,6S,6aS,12R,12aS,12bS)-4-(acetoxymethyl)-12-hydroxy-4,6a,12b-trimethyl-11-oxo-9-(pyridin-3-yl)-1,3,4,4a,5,6,6a,12,12a,12b-decahydro-2H,11H-benzo[f]pyrano[4,3-b]chromene-3,6-diol in which the hydrogens of the 3- and 6-hydroxy functions are substituted by acetyl groups.

Filing pathway
Unclassified — 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.

SOURCE_ASSERTION | mibig:BGC0000129 | PMID:20861902 |
Occurrences 6
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.
