Experientia, 1949
Die Erwagungen, welche die Autoren zu der Struktur I fur Patulin fuhrten, werden kurz beschrieben, und es wird gezeigt, das das chemische Verhalten des Naturstoffes in jeder Hinsicht durch diese Strukturformel zu erklaren ist.

Patulin: Mechanism of genotoxicity
Food and Chemical Toxicology, 2012Patulin is a frequently found food contaminant mainly produced by the fungi Aspergillus and Penicillium. Patulin is suspected to be clastogenic, mutagenic, teratogenic and in higher concentrations cytotoxic. Here, we investigate the mechanism of the patulin-induced genotoxicity.

Australian Journal of Chemistry, 2001
Two new derivatives of patulin (1), the dimer (2) arising from cycloaddition at the 3,4-double bond, and 3,4-dihydroxypatulin acetonide (4), from attempted epoxidation with dimethyldioxirane, have been characterized. The structure of (2) was established by a single-crystal low-temperature X-ray study, while that of (4) was deduced from spectroscopic ...

Production of patulin by Micromycetes
Mycopathologia, 1989In the context of the screening for antifungal and antibacterial molecules among the Micromycetes, we investigated the ability of 850 strains grown in liquid medium to produce patulin. The compound was produced by 58 fungi, most of which had not been mentioned in the literature, especially Mucorales and Fungi Imperfecti.

The spasmolytic effect of patulin
Experientia, 1958Patulin verhindert die Kontraktion des isolierten Meerschweinchenileums, verursacht durch Nikotin, Histamin, 5-Hydroxytryptamin, Pilokarpin, Acetylcholin und Prostaglandin. Die Kontraktion, verursacht durch Substanz P und Barium Chloride, wird nicht verhindert.

Antitumoral activity of patulin and patulin-cysteine adducts.
Die Pharmazie, 1994A comparison between the cytotoxicity and the anti-tumoral activity of patulin and patulin-cysteine adducts has been conducted. In vitro assays using L 1210 and P 388 cells showed that patulin-cysteine adducts had less cytotoxic activity than patulin (IC50 was 4 fold of IC50 patulin).

Current Opinion in Food Science, 2015
Patulin is produced by species of Penicillium, Aspergillus and Byssochlamys. It is a mycotoxin that primarily contaminates pome fruit products, but is being reported from other fruit and foods, for example shellfish and cheese. New findings reveal that patulin binds to the bases of DNA, in addition to its well-established ability to conjugate ...

Mikotoksinler, mantarlar tarafından sekonder metabolitler olarak üretilen güçlü toksinlerdir. Güçlü toksisitesinden dolayı besin güvenliği ve gıda sanayisi bu metabolitleri üzerinde durulması gereken bir konu olarak değerlendirmektedir. Bir mikotoksin türü olan patulin, Byssochlamys, Penicillium, Aspergillus gibi bazı mantarlar tarafından üretilen ve ...
