CHEBI:232090 EXACT SEEDED

A pyrrolopyrazine that is pyrrolo[1,2-a]pyrazin-1(2H)-one substituted by methyl and 3-carbamimidamidopropyl groups at positions 2 and 3, respectively. It is isolated from perennial ryegrass infected with the endophytic fungus Acremonium lolia and exhibits antifeedant activity.

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, 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.
