Lumpidin, a Novel Biomarker of Some Ochratoxin A Producing Penicillia
Abstract
The novel compound lumpidin (1) has been isolated as a major compound from an isolate of Penicillium nordicum. Compound 1 is a diketopiperazine with a unique ring system likely to be a condensate of one mole each of L-tryptophan, L-phenylalanine, and L-homo-proline. The fact that 1 has been detected from only three out of sixteen isolates of P. nordicum indicates that lumpidin-producing isolates might represent a separate and third ochratoxin A producing Penicillium species.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
