tropodithietic acid

CHEBI:156455 EXACT SEEDED antibacterialcytotoxic

A monocarboxylic acid that is 8,9-dithiabicyclo[5.2.0]nona-1,3,6-triene substituted by a carboxy group at position 2 and an oxo group at position 3. It is a broad spectrum antibiotic produced by the marine bacterium Phaeobacter inhibens that also acts as a signalling molecule at lower concentrations.

Filing pathway

Shikimates and phenylpropanoids — 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 other, 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.
